1 Drupal 8.4.5, 2018-02-20
2 ------------------------
3 - Fixed security issues. See SA-CORE-2018-001.
5 Drupal 8.4.0, 2017-10-04
6 ------------------------
7 ### Drush users: Update to Drush 8.1.12+ or higher
9 [Versions of Drush earlier than 8.1.12 will not work with Drupal
10 8.4.x](https://www.drupal.org/node/2874827). Update Drush to 8.1.12 or higher
11 **before using it to update to Drupal core 8.4.x** or you will encounter fatal
12 errors that prevent updates from running.
14 * If Drush is installed globally (i.e., generally available on the web host),
15 Drush 8.1.12 and higher will successfully update Drupal 8.3.x to 8.4.0, but
16 users may still see [other error messages after updates have
17 run](https://github.com/drush-ops/drush/issues/2933).)
18 * If the site is built with Composer and includes Drush as a local dependency
19 (less common), you should update your `composer.json` file to require at
20 least [Drush 8.1.15](https://github.com/drush-ops/drush/releases/tag/8.1.15).
21 Drush 8.1.14 will not work in the same composer project as Drupal 8.4.
23 ### Updated browser requirements: Internet Explorer 9 and 10 no longer supported
25 In April 2017, Microsoft discontinued all support for Internet Explorer 9 and
26 10. Therefore, [Drupal 8.4 has as well](https://www.drupal.org/node/2842298).
27 Drupal 8.4 still mostly works in these browser versions, but bugs that affect
28 them only will no longer be fixed, and existing workarounds for them will
29 be removed beginning in Drupal 8.5.
31 Additionally, Drupal 8's [browser requirements documentation
32 page](https://www.drupal.org/docs/8/system-requirements/browser-requirements)
33 currently lists incorrect information regarding very outdated browser versions
34 such as Safari 5 and Firefox 5. [Clarifications to the browser policy and
35 documentation](https://www.drupal.org/node/2390621) are underway.
39 Drupal 8.4.0 includes major version updates for two dependencies:
40 Symfony 3.2 and jQuery 3. Both updates may introduce backwards compatibility
41 issues for some sites or modules, so test carefully. For more information, see
42 the "Third-party library updates" section below. Known issues related to the
43 Symfony update include:
46 * [Incompatibility with Drush 8.1.11 and earlier](https://www.drupal.org/node/2874827).
47 * [Other error messages with Drush 8.1.12 and higher](https://github.com/drush-ops/drush/issues/2933).
48 * [Incompatibility with Drush 8.1.14 and earlier for Composer-built sites](https://github.com/drupal-composer/drupal-project/issues/305).
49 * [Certain file uploads may fail
50 silently](https://www.drupal.org/node/2906030) due to a Symfony 3 backwards
51 compatibility break if they used the `$deep` parameter (which was already
52 deprecated in Symfony 2.8 and is removed in Symfony 3.0. *Check any custom
53 file upload code* that may have used the deprecated parameter and [update
54 it according to the API change record](https://www.drupal.org/node/2743809).
56 See the ['8.4.0 update' tag for a list of known issues across
57 projects](https://www.drupal.org/project/issues/search?issue_tags=8.4.0%20update).
59 [Search the issue queue for known
60 issues](https://www.drupal.org/project/issues/search/drupal?project_issue_followers=&status%5B%5D=Open&version%5B%5D=8.x&issue_tags_op=%3D).
62 ### Important fixes since 8.3.x
64 Translators should take note of several [string additions and changes since the
65 last release](https://www.drupal.org/project/issues/search/drupal?project_issue_followers=&issue_tags_op=%3D&issue_tags=String+change+in+8.4.0).
67 #### File usage tracking
69 Drupal 8 has several longstanding [file usage tracking
70 bugs](https://www.drupal.org/node/2821423). To prevent further data loss,
71 Drupal 8.4 has [disabled the automatic deletion of files with no known
72 remaining usages](https://www.drupal.org/node/2801777). This will result of the
73 accumulation of unused files on sites, but ensures that files erroneously
74 reporting 0 usages are not deleted while in use. Additionally, an issue with
75 [validation errors when saving content referencing these
76 files](https://www.drupal.org/node/2896480) has also been resolved.
78 [The change record explains how sites can opt back into marking files
79 temporary](https://www.drupal.org/node/2891902). If you choose to enable the
80 setting, you can also set "Delete orphaned files" to "Never" on
81 `/admin/config/media/file-system` to avoid permanent deletion of the affected
84 While the files will no longer be deleted by default, file usage is still not
85 tracked correctly in several scenarios, regardless of the setting. Discussion
86 on [how to evolve the file usage tracking
87 system](https://www.drupal.org/node/2821423) is underway.
89 #### Configuration export sorting
91 * [#2361539: Config export key order is not predictable for sequences, add
92 orderby property to config schema](https://www.drupal.org/node/2361539)
93 resolves an issue where sequences in configuration were not sorted unless
94 the code responsible for saving configuration explicitly performed a sort.
95 This resulted in unpredictable changes in configuration ordering and
96 confusing diffs even when nothing had changed. To resolve this issue, we've
97 [added an `orderby` key to the config schema](https://www.drupal.org/node/2852566)
98 that allows it to be sorted either by key or by value. Adding a preferred
99 sort is strongly recommended.
100 * Two related issues remain open:
101 * [#2860531: Add orderby key to third-party
102 settings](https://www.drupal.org/node/2860531) relates to unsorted
103 sequences which result in unexpected discrepancies in configuration
104 during a configuration import.
105 * [#2885368: Config export key order for sequences: "orderedby" does not
106 support cases where the order actually
107 matters](https://www.drupal.org/node/2885368) relates to various
108 sequences in core and contributed modules in which the source order is
111 #### Revision data integrity fixes
113 * Previously, data from draft revisions for
114 [path aliases](https://www.drupal.org/node/2856363),
115 [menus](https://www.drupal.org/node/2858434),
116 and [books](https://www.drupal.org/node/2858431) could leak into the live
117 site. Drupal 8.4.0 hotfixes all three issues by preventing changes to
118 this data from being saved on any revision that is not the default revision.
119 These fixes improve revision support for both stable features and the
120 experimental Content Moderation module.
121 * Correspondingly, [Content Moderation now avoids such scenarios with
122 non-default revisions](https://www.drupal.org/node/2883868) by setting the
123 'default revision' flag earlier.
124 * Previously, [saving a revision of an entity translation could cause draft
125 revisions to go "missing"](https://www.drupal.org/node/2766957). Drupal 8.4.0
126 prevents this by preventing the moderation state from being set to anything
127 that would make the revision go "missing". Going forward, the entity system
128 will also [provide the 'revision_translation_affected' base field by default
129 for all revisionable and translatable entity
130 types](https://www.drupal.org/node/2896845) for tracking such revisions.
131 * [A similar but unrelated bug in
132 Content Moderation](https://www.drupal.org/node/2862988) has also been fixed
135 #### Other critical improvements
137 * When nodes were deleted, Menu UI module deleted their menu items. However,
138 menu items may exist even whenm Menu UI module is not enabled and can also be
139 attached to entities other than nodes. Therefore, menu item cleanup on entity
140 deletetion [is now performed by the Custom Menu Links
141 module](https://www.drupal.org/node/2350797) instead, covering the previously
142 missing cases. A related issue that [broke module uninstallation for some
143 modules providing menu items for certain entity
144 forms](https://www.drupal.org/node/2907654) has also been resolved.
145 * A race condition occured in the Batch API when using fastcgi. The Batch API
146 now ensures that [the current batch state is written completely to the
147 database before starting the next
148 batch](https://www.drupal.org/node/2851111).
149 * When uninstalling modules, empty fields were left behind to be purged.
150 However, without the field definitions from the module, it was not possible
151 to purge them any more. [Empty field deletion is now performed
152 immediately](https://www.drupal.org/node/2884202) instead to avoid this
154 * When clearing caches in a translated interface, the field labels would
155 [return to the default language](https://www.drupal.org/node/2650434).
157 ### New stable modules
159 The following modules, previously considered experimental, are now stable and
160 safe for use on production sites, with full backwards compatibility and upgrade
161 paths from 8.4.0 to future releases:
165 The [Datetime Range module](https://www.drupal.org/node/2893128) provides a
166 field type that allows end dates to support contributed modules like
167 [Calendar](https://www.drupal.org/project/calendar). This stable release is
168 backwards-compatible with the 8.3.x experimental version and shares a
169 consistent API with other Datetime fields.
171 Future releases may improve Views support, usability, Datetime Range field
172 validation, and REST support. For bugs or feature requests for this module,
173 [see the core Datetime issue
174 queue](https://www.drupal.org/project/issues/search/drupal?project_issue_followers=&status%5B%5D=Open&version%5B%5D=8.x&component%5B%5D=datetime.module&issue_tags_op=%3D).
176 #### Layout Discovery
178 The [Layout Discovery module](https://www.drupal.org/node/2834025) provides
179 an API for modules or themes to register layouts as well as five common
180 layouts. Providing this API in core enables core and contributed layout
181 solutions to be compatible with each other. This stable release is
182 backwards-compatible with the 8.3.x experimental version and introduces
183 [support for per-region attributes](https://www.drupal.org/node/2885877).
187 The new core [Media module](https://www.drupal.org/node/2831274) provides an
188 API for reusable media entities and references. It is based on the contributed
189 [Media Entity module](https://www.drupal.org/project/media_entity).
191 Since there is a rich ecosystem of Drupal contributed modules built on Media
192 Entity, the top priority for this release is to [provide a stable core API and
193 data model](https://www.drupal.org/node/2895059) for a smoother transition for
194 these modules. Developers and expert site builders can now add Media as a
195 dependency. Work is underway to [provide an update path for existing sites'
196 Media Entity data](https://www.drupal.org/node/2880334) and to [port existing
197 contributed modules to the improved core
198 API](https://www.drupal.org/node/2860796). Both versions cannot be used at the
199 same time, so we also [prevent the 1.x version of the contributed Media Entity
200 module from being enabled at the same time as the core Media
201 module](https://www.drupal.org/node/2896427).
203 Note that **the core Media module is currently marked hidden** and will not
204 appear on the 'Extend' (module administration) page. (Enabling a contributed
205 module that depends on the core Media module will also enable Media
206 automatically.) The module will be displayed to site builders normally once
207 user experience issues with it are resolved. Similarly, the REST API and
208 normalizations for Media is not final and support for decoupled applications
209 will also be improved in a future release.
211 #### Inline Form Errors
213 The [Inline Form Errors module](https://www.drupal.org/node/2897652) provides a
214 summary of any validation errors at the top of a form and places the individual
215 error messages next to the form elements themselves. This helps users
216 understand which entries need to be fixed, and how. Inline Form Errors was
217 provided as an experimental module from Drupal 8.0.0 on, but it is now stable
218 and polished enough for production use. See the core [Inline Form Errors module
219 issue queue](https://www.drupal.org/project/issues/drupal?text=&status=Open&priorities=All&categories=All&version=All&component=inline_form_errors.module)
220 for outstanding issues.
224 The Workflows module provides an abstract system of states (like Draft,
225 Archived, and Published) and transitions between them. Workflows can be used by
226 modules that implement non-publishing workflows (such as for users or products)
227 as well as content publishing workflows.
229 Drupal 8.4 introduces a final significant backwards compatibility and data
230 model break for this module, [moving responsibility for workflow states and
231 transitions from the Workflow entity to the Workflow type
232 plugin](https://www.drupal.org/node/2849827). Read [Workflow type plugins are
233 now responsible for state and transition
234 schema](https://www.drupal.org/node/2897706) for full details on the API and
235 data model changes related to this fix. Now that this change is complete, [the
236 Workflows module became stable](https://www.drupal.org/node/2897130)!
238 While the module can be installed as-is, it is not useful in itself without
239 either Content Moderation and/or some other module that requires it.
241 ### Content authoring and site administration improvements
243 * The "Save and keep (un)published" dropbutton has been replaced with [a
244 "Published" checkbox and single "Save"
245 button](https://www.drupal.org/node/2068063). The "Save and..." dropbutton
246 was a new design in Drupal 8, but users found it confusing, so we have
247 restored a design that is more similar to the user interface for Drupal 7 and
249 * Previously, deleting a field on a content type would also delete any views
250 depending on the field. While the confirmation form did indicate that the
251 view would be deleted, users did not expect the behavior and often missed the
252 message, leading to data loss. [Now, the view is disabled
253 instead](https://www.drupal.org/node/2468045). In the future, we intend to
254 [notify users that configuration has been
255 disabled](https://www.drupal.org/node/2832558) (as in this fix) as well as
256 [give users clearer warnings for other highly destructive
257 operations](https://www.drupal.org/node/2773205).
258 * The [Drupal toolbar no longer flickers](https://www.drupal.org/node/2542050)
259 during page rendering, thus improving perceived front-end performance.
260 * Options in [timezones selector are now grouped by
261 regions](https://www.drupal.org/node/2847651) and labeled by cities instead
262 of timezone names, making it much easier for users to find and select the
263 specific timezone they need.
264 * Both the ["Comments" administration page at
265 `/admin/content/comment`](https://www.drupal.org/node/1986606) and the
266 ["Recent log messages" report provided by
267 dblog](https://www.drupal.org/node/2015149) are now configurable views. The
268 "Comments" administration page also [has some default filters
269 added](https://www.drupal.org/node/2898344).
270 * Useful meta information about a node's status is typically displayed at the
271 top of the node sidebar. Previously, this meta information was provided by
272 the Seven theme, so it was not available in other administrative themes.
273 [This meta information is now provided by node.module
274 itself](https://www.drupal.org/node/2803875) so other administration themes
276 * [Views now supports rendering computed
277 fields](https://www.drupal.org/node/2852067).
279 ### REST and API-first improvements
281 * Authenticated REST API performance increased by 15% by [utilizing the Dynamic
282 Page Cache](https://www.drupal.org/node/2827797).
283 * POSTing entities [can now happen at `/node`, `/taxonomy/term` and so
284 on](https://www.drupal.org/node/2293697), instead of `/entity/node`,
285 `/entity/taxonomy_term`. Instead of confusingly different URLs, they therefore
286 now use the URLs you'd expect. Backwards compatibility is maintained.
287 * There is now a dedicated resource for [resetting a user's
288 password](https://www.drupal.org/node/2847708).
289 * Time fields now are [normalized to RFC3339 timestamps by
290 default](https://www.drupal.org/node/2768651), fixing time ambiguity.
291 Existing sites continue to receive UNIX timestamps, but can opt in. [See the
292 change record for more information about backwards compatibility and on how
293 to opt in](https://www.drupal.org/node/2859657).
294 * [Path alias fields are now normalized as
295 well](https://www.drupal.org/node/2846554). [See the change record for
296 information about how this impacts API-first modules and other features
297 relying on serialized entities](https://www.drupal.org/node/2856220).
298 * When denormalization fails, a [422 response is now
299 returned](https://www.drupal.org/node/2827084) instead of a 400, per the HTTP
301 * With CORS enabled to allow origins besides the site's own host, [submitting
302 forms was broken](https://www.drupal.org/node/2853201) unless the site's own
303 host was also explicitly allowed. This is now resolved.
304 * Fatal errors and exceptions [now show a
305 backtrace](https://www.drupal.org/node/2853300) for all non-HTML requests as
306 well as HTML requests, which makes for easier debugging and better bug
308 * Massive expansion of test coverage.
310 ### Performance and scalability improvements
312 * Drupal 8 caches at various different levels for more effective caching.
313 However, this resulted in exessively growing cache tables with tens or
314 hundreds of thousands of entries, and gigabytes in size. [A new limit of 5000
315 rows per cache bin was introduced to limit this
316 growth](https://www.drupal.org/node/2526150).
317 * The internal page cache now [has a dedicated cache
318 bin](https://www.drupal.org/node/2889603) distinct from the rest of the
319 render cache for improved scalability.
320 * The service collector pattern instantiates all services it collects, which is
321 expensive, and unnecessary for some use cases. For those use cases, a [new
322 service ID collector](https://www.drupal.org/node/2472337) pattern has been
323 added and the theme negotiator updated to use it. [See the change record for
324 information about how to use the service ID
325 collector](https://www.drupal.org/node/2598944) for improved performance.
326 * The maximum time in-progress forms are cached [is now
327 customizable](https://www.drupal.org/node/1286154) rather than being limited
328 to a default cache lifetime of 6 hours. Sites can decrease the lifetime to
329 reduce cache footprint, or increase it if needed for a particular site's
330 usecase. [See the change record to learn how to access this new
331 setting](https://www.drupal.org/node/2886836).
332 * If there are no status messages, the corresponding rendering [is now
333 skipped](https://www.drupal.org/node/2853509). On simple sites that use the
334 Dynamic Page Cache (the default), this can result in a 10% improvement when
335 there are no messages!
336 * [Optimized the early Drupal installer](https://www.drupal.org/node/2872611)
337 to check whether any themes are installed first before invoking an
338 unnecessary function, which improves Drupal install time measurably for both
339 sites and automated tests.
341 ### Developer experience improvements
343 * [Adopted Airbnb JavaScript style guide
344 14.1](https://www.drupal.org/node/2815077) as the new baseline set of coding
345 standards for Drupal core and contributed modules. [See the change record for
346 information about how to configure your project for
347 eslint](https://www.drupal.org/node/2873849).
348 * Field type definitions can now [enforce the cardinality of the
349 field](https://www.drupal.org/node/2403703). [See the change record for
350 information about how to specify a cardinality via the
351 annotation](https://www.drupal.org/node/2869873).
352 * [Added new methods](https://www.drupal.org/node/2869809) to make getting
353 typed configuration entity representations easier. [See the change record for
354 more information about how to invoke these
355 methods](https://www.drupal.org/node/2877282).
356 * The `html_tag` render element now [supports nested render
357 arrays](https://www.drupal.org/node/2694535), enabling the creation of
358 dynamic SVGs. [See the change record for information about how you can use
359 this in your theme](https://www.drupal.org/node/2887146).
360 * [Added more helpful errors](https://www.drupal.org/node/2705037) when CSS
361 is not properly nested under an existing category in asset libraries.
362 * Also see the [change records for the 8.4.x
363 branch](https://www.drupal.org/list-changes/drupal/published?keywords_description=&to_branch=8.4.x&version=&created_op=%3E%3D&created%5Bvalue%5D=&created%5Bmin%5D=&created%5Bmax%5D=)
364 for other changes for developers.
366 ### Automated testing improvements
368 * [PHPUnit has been updated from 4.8.28 to
369 4.8.35](https://www.drupal.org/node/2850797) in order to incorporate a
370 forward-compatibility layer for PHPUnit 4.8, which will be useful during a
371 future migration to PHPUnit 5 or PHPUnit 6.
372 * Many former WebTestBase tests were converted to BrowserTestBase. [Track
373 current progress](http://simpletest-countdown.org/).
374 * The default approach for testing deprecated code has changed to [require use
375 of the Drupal core deprecation policy](https://www.drupal.org/node/2488860)
376 (`@trigger_error()`) to mark code deprecated; otherwise a test error will
377 be thrown. [See the change record for information about how to update
378 `phpunit.xml` and how to test deprecated
379 code](https://www.drupal.org/node/2811561).
380 * BrowserTestBase is [no longer dependent on traits from
381 Simpletest](https://www.drupal.org/node/2803621). Backwards
382 compatibility is preserved.
383 * [Resolved random test failures](https://www.drupal.org/node/2866056) due to
384 ResourceTestBase's HTTP client timeout of 30 seconds.
386 ### Third-party library updates
388 * [Drupal's Symfony dependency has been updated from Symfony 2.8 to Symfony
389 3.2](https://www.drupal.org/node/2712647). This major version update is
390 necessary because Symfony 2.8 support will end around the release of Drupal
391 8.6.0 next year. See the change record for information about [Symfony 3
392 backwards compatibility breaks that affected Drupal
393 core](https://www.drupal.org/node/2743809). [Drupal 8 also requires Symfony
394 3.2.8](https://www.drupal.org/node/2871253) because of a bug in Symfony
396 * [#2533498: Update jQuery to version 3](https://www.drupal.org/node/2533498).
397 Now that jQuery 3.0 has been released, jQuery 2.x will only be receiving
398 security updates, so Drupal 8.4.0 ships with this library update. jQuery 3
399 features numerous improvements, including better error reporting. See the
400 [jQuery Core 3.0 Upgrade Guide](https://jquery.com/upgrade-guide/3.0/) for
401 information on jQuery 3 backwards compatibility breaks that might affect the
402 JavaScript code in your modules, themes, and sites.
403 * The zurb/joyride library (used by the Tour module) has been [updated to a
404 development version higher than 2.1.0.1](https://www.drupal.org/node/2898808)
405 to resolve an upstream incompatibility with jQuery 3. We will update to
406 Joyride 2.1.1 once it is available with the needed fix.
407 * [zendframework/zend-diactoros has been updated from 1.3.10 to 1.4.1](https://www.drupal.org/node/2874817).
408 * [jQuery UI has been updated from 1.11.4 to 1.12.1](https://www.drupal.org/node/2809427).
409 * [jQuery Once has been updated from 2.1.1 to 2.2.0](https://www.drupal.org/node/2899156).
410 * [CKEditor has been updated from 4.6.2 to 4.7.2](https://www.drupal.org/node/2904142).

421 ### Experimental modules
423 #### Migrate ([beta stability](https://www.drupal.org/core/experimental#beta))
425 Migrate provides a general API for migrations. It will be considered completely
426 stable once all issues tagged [Migrate
427 critical](https://www.drupal.org/project/issues/search/drupal?project_issue_followers=&status%5B%5D=Open&version%5B%5D=8.x&issue_tags_op=%3D&issue_tags=Migrate+critical)
430 * This release includes numerous developer experience improvements for Migrate
431 and Migrate Drupal, including [deprecating outdated references to
432 "CCK"](https://www.drupal.org/node/2751897), [simplifying field type
433 mapping](https://www.drupal.org/node/2896507), renaming several plugins to
434 better capture their and many other API and documentation improvements.
435 (Backwards compatibility is provided in each case Migrate is in beta.)
436 * Added the ability to [provide the source
437 module](https://www.drupal.org/node/2569805) to migrations to help site
438 owners review what data is being migrating, especially for cases where the
439 source and destination module are not the same (for example if a new Drupal 8
440 module replaces old functionality.
443 #### Migrate Drupal and Migrate Drupal UI ([alpha stability](https://www.drupal.org/core/experimental#alpha))
445 Migrate Drupal module provides API support for Drupal-to-Drupal migrations, and
446 Migrate Drupal UI offers a simple user interface to run migrations from older
449 * This release adds [date](https://www.drupal.org/node/2566779) and
450 [node reference](https://www.drupal.org/node/2814949) support for Drupal 6 to
452 * Core provides migrations for most Drupal 6 data and can be used for migrating
453 Drupal 6 sites to Drupal 8, and the Drupal 6 to 8 migration path is nearing
454 beta stability. Some gaps remain, such as for some internationalization data.
455 ([Outstanding issues for the Drupal 6 to Drupal 8
456 migration](https://www.drupal.org/project/issues/search/drupal?project_issue_followers=&status%5B%5D=1&status%5B%5D=13&status%5B%5D=8&status%5B%5D=14&status%5B%5D=15&status%5B%5D=4&issue_tags_op=%3D&issue_tags=migrate-d6-d8).)
457 * The Drupal 7 to Drupal 8 migration is incomplete but is suitable for
458 developers who would like to help improve the migration and can be used to
459 test upgrades especially for simple Drupal 7 sites. Most high-priority
460 migrations are available. ([Outstanding issues for the Drupal 7 to Drupal 8
461 migration](https://www.drupal.org/node/2456259).)
462 * Drush support for Migrate is currently only available in the
463 [Drupal Upgrade](https://www.drupal.org/project/migrate_upgrade) contributed
464 module. (See the [pull request to add support to
465 Drush](https://github.com/drush-ops/drush/issues/2140).)
466 * Conflicting text field processing settings [are now identified and
467 logged](https://www.drupal.org/node/2842222) to avoid security or data
468 integrity issues with the migration of plain and formatted text fields.
469 * Automatic redirects are now [added for translation node paths that are no
470 longer valid](https://www.drupal.org/node/2850085) after migration has merged
471 translations into a single node.
472 * A data integrity bug that resulted in [duplicate comment types and incorrect
473 comment_entity_statistics](https://www.drupal.org/node/2853872) for node and
474 forum comment migrations has been resolved.
475 * A bug that [stopped public files from being migrated from D6 to D8 if the
476 user first selected Drupal 7 in the UI](https://www.drupal.org/node/2907233)
477 has also been resolved.
479 #### Content Moderation ([beta stability](https://www.drupal.org/core/experimental#beta))
481 Content Moderation allows workflows from the Workflows module to be applied to
482 content. Content Moderation has beta stability in 8.4.0-alpha1. Notable improvements in this release:
484 * Workflow states are now [selected from a select list, rather than under a drop-button](https://www.drupal.org/node/2753717), which represents a significant
485 usability improvement.
486 * Now that workflows can be applied to any revisionable entity type, Content
487 Moderation [adds entity type checkboxes to the workflow form](https://www.drupal.org/node/2843083).
488 This allows site administrators to configure which entity types should have
489 the workflow at the same time as they configure the workflow itself, for a
490 more intuitive user experience.
491 * Content Moderation now [prevents the deletion of workflows that are currently in use](https://www.drupal.org/node/2830740)
492 to prevent fatal errors and data integrity problems.
493 * The confusing terminology of
494 ["forward revisions" has been replaced with that of "pending revisions"](https://www.drupal.org/node/2890364).
495 If your contributed module refers to revisions that are not yet published, it
496 should use this new term.
497 * [The 'Latest revision' views filter has been rewritten to avoid relying on a
498 custom {revision_tracker}](https://www.drupal.org/node/2865579), and that
499 table has been removed from the database schema.
501 As per the experimental module process, there were some backwards-incompatible
502 changes since Drupal 8.3.x. Experimental modules do not offer a supported
503 upgrade path, but [an unofficial upgrade path is
504 available](https://www.drupal.org/node/2896630).
506 #### Field Layout ([alpha stability](https://www.drupal.org/core/experimental#alpha))
508 This module provides the ability for site builders to rearrange fields on
509 content types, block types, etc. into new regions, for both the form and
510 display, on the same forms provided by the normal field user interface. Field
511 Layout has had several bugfixes since 8.3.0, but no significant changes. See
512 the [entity display layout roadmap](https://www.drupal.org/node/2795833) for
513 the next steps for this module, which needs to become stable by 8.5.0 to remain
516 #### Settings Tray ([beta stability](https://www.drupal.org/core/experimental#beta))
518 The Settings Tray module allows configuring page elements such as blocks and
519 menus from the frontend of your site. Settings Tray has improved significantly
520 since Drupal 8.3.0, including numerous user interaction and accessibility
521 fixes, better compatibility with stable core modules like Quick Edit and
522 Contextual Links, added documentation, and [a CSS
523 reset](https://www.drupal.org/node/2826722) for better themer experience.
525 The module reached beta stability following completion of [moving the
526 off-canvas dialog renderer into a core
527 component](https://www.drupal.org/node/2784443), and [renaming the machine name
528 of the module to settings_tray](https://www.drupal.org/node/2803375), to match
529 its user-facing name. We hope to make Settings Tray stable by 8.5.0. To track
530 progress, see the ["outside in" roadmap issue](https://www.drupal.org/node/2762505).
532 #### Place Blocks ([alpha stability](https://www.drupal.org/core/experimental#alpha))
534 This feature allows the user to place a block on any page and see the region
535 where it will be displayed, without having to navigate to a backend
536 administration form. [8.4.0-alpha1 was the deadline for Place Blocks to
537 stabilize](https://www.drupal.org/core/experimental#versions), but the module's
538 roadmap was not completed. Furthermore, the module is not intended as a
539 standalone feature and should instead be a built-in part of the Block system.
540 For these reasons, [Place Blocks module has been marked hidden in this
541 release](https://www.drupal.org/node/2898267) (it can still be enabled with
542 Drush). The Place Blocks module itself will be turned into an empty module in
543 Drupal 8.5.x, since ideally the core Block system will offer the same
544 functionality in 8.5.0 (though this depends on completion of a [core patch for
545 the feature](https://www.drupal.org/node/2739075).)
547 Drupal 8.3.0, 2017-04-05

585 - Improved site building and administration:
586 * Redesigned status report.
587 * Standardized display of Views overview page to more closely match that of
588 other administrative overview pages.
589 * Views filter order now matches the table column order below in Content
590 and People overview pages.

627 - Improved developer APIs:
628 * Deprecated several routing services in favor of two more unified services.
629 * Replaced the deprecated Symfony ExecutionContextInterface by subclassing
630 from ConstraintValidator to prepare for an update to Symfony 3.
631 * EntityPublishedInterface and EntityPublishedTrait have been added to give
632 a generic publishing API, and are being used by Node and Comment entity
634 * Added a collection label to EntityType. This is a plural uppercase label
635 for a collection of entities - e.g. "Workflows".
636 - Changed coding standards:
637 * Officially adopted short array syntax and updated all of core accordingly.
638 * PHP CodeSniffer and Drupal Coder have been added as composer dev
639 requirements, so they can be installed automatically with
640 `composer install --dev` rather than requiring separate installation. (Do
641 not use `composer install --dev` for production sites.)
642 * Most global constants in Drupal 8 have been deprecated in favor of class
643 constants. As a best practice, use appropriate class constants rather than

1062 * Implemented a pluggable password system and much stronger password hashes
1063 that are compatible with the Portable PHP password hashing framework.
1064 * Rate limited login attempts to prevent brute-force password guessing, and
1065 improved the flood control API to allow variable time windows and
1066 identifiers for limiting user access to resources.
1067 * Transformed the "Update status" module into the "Update manager" which
1068 can securely install or update modules and themes via a web interface.
1070 * Added contextual links (a.k.a. local tasks) to page elements, such as
1071 blocks, nodes, or comments, which allows to perform the most common tasks
1072 with a single click only.
1073 * Improved installer requirements check.
1074 * Improved support for integration of WYSIWYG editors.
1075 * Implemented drag-and-drop positioning for input format listings.

1085 implemented a "slimmed down" profile designed for developers.
1086 * Added a built-in, automated cron run feature, which is triggered by site
1088 * Added an administrator role which is assigned all permissions for
1089 installed modules automatically.

1124 * Drupal now uses PHP's time zone database when rendering dates in local
1125 time. Site-wide and user-configured time zone offsets have been converted
1126 to time zone names; for example, Africa/Abidjan.
1127 * In some cases the upgrade and install scripts do not choose the preferred
1128 site default time zone. The automatically-selected time zone can be
1129 corrected at admin/config/regional/settings.
1130 * If your site is being upgraded from Drupal 6 and you do not have the
1131 contributed date or event modules installed, user time zone settings will
1132 fallback to the system time zone and will have to be reconfigured by each user.

1144 previous functionality in the user module for restricting certain email
1145 addresses and usernames is now available as a contributed module. Further,
1146 IP address range blocking is no longer supported and should be implemented
1147 at the operating system level.
1148 * Removed per-user themes: Contributed modules with similar functionality
1151 * Added support for Gmail and Google Apps for Domain identifiers. Users can
1152 now log in with their user@example.com identifier when example.com is
1154 * Made the OpenID module more pluggable.
1155 - Added code registry:
1156 * Using the registry, modules declare their includable files via their .info file,
1157 allowing Drupal to lazy-load classes and interfaces as needed.
1159 * Removed the Bluemarine, Chameleon and Pushbutton themes. These themes live
1160 on as contributed themes (https://www.drupal.org/project/bluemarine,
1161 https://www.drupal.org/project/chameleon and
1162 https://www.drupal.org/project/pushbutton).
1163 * Added Stark theme to make analyzing Drupal's default HTML and CSS easier.
1164 * Added Seven as the default administration theme.
1165 * Variable preprocessing of theme hooks prior to template rendering now goes
1166 through two phases: a 'preprocess' phase and a new 'process' phase. See
1167 http://api.drupal.org/api/function/theme/7 for details.
1168 * Theme hooks implemented as functions (rather than as templates) can now
1169 also have preprocess (and process) functions. See
1170 http://api.drupal.org/api/function/theme/7 for details.
1171 * Added Bartik as the default theme.
1173 * Files are now first class Drupal objects with file_load(), file_save(),
1174 and file_validate() functions and corresponding hooks.
1175 * The file_move(), file_copy() and file_delete() functions now operate on
1176 file objects and invoke file hooks so that modules are notified and can
1178 * For the occasions when only basic file manipulation are needed--such as
1179 uploading a site logo--that don't require the overhead of databases and
1180 hooks, the current unmanaged copy, move and delete operations have been
1181 preserved but renamed to file_unmanaged_*().
1182 * Rewrote file handling to use PHP stream wrappers to enable support for
1183 both public and private files and to support pluggable storage mechanisms
1184 and access to remote resources (for example, S3 storage or Flickr photos).
1185 * The mime_extension_mapping variable has been removed. Modules that need to
1186 alter the default MIME type extension mappings should implement
1187 hook_file_mimetype_mapping_alter().
1188 * Added the hook_file_url_alter() hook, which makes it possible to serve
1190 * Added a field specifically for uploading files, previously provided by
1191 the contributed module FileField.

1205 * Added support for RDFa export of nodes, comments, terms, users, etc. and
1207 - Search engine optimization and web linking:
1208 * Added a rel="canonical" link on node and comment pages to prevent
1209 duplicate content indexing by search engines.
1210 * Added a default rel="shortlink" link on node and comment pages that
1211 advertises a short link as an alternative URL to third-party services.
1212 * Meta information is now alterable by all modules before rendering.
1214 * Custom data fields may be attached to nodes, users, comments and taxonomy
1216 * Node bodies and teasers are now Field API fields instead of
1217 being a hard-coded property of node objects.
1218 * In addition, any other object type may register with Field API
1219 and allow custom data fields to be attached to itself.
1220 * Provides most of the features of the former Content Construction
1222 * Taxonomy terms are now Field API fields that can be added to any fieldable
1225 * Refactored the installer into an API that allows Drupal to be installed
1226 via a command line script.

1248 modules with similar functionality are available:
1252 - Improved node access control system.
1253 * All modules may now influence the access to a node at runtime, not just
1254 the module that defined a node.
1255 * Users may now be allowed to bypass node access restrictions without giving
1256 them complete access to the site.
1257 * Access control affects both published and unpublished nodes.

1987 Drupal 3.0.0, 2001-09-15
1988 ------------------------
1989 - Major overhaul of the entire underlying design:
1990 * Everything is based on nodes: nodes are a conceptual "black box" to couple and manage different types of content and that promotes reusing existing code, thus reducing the complexity and size of Drupal as well as improving long-term stability.
1991 - Rewrote submission/moderation queue and renamed it to queue.module.
1992 - Removed FAQ and documentation module and merged them into a "book module".
1993 - Removed ban module and integrated it into account.module as "access control":
1994 * Access control is based on much more powerful regular expressions (regex) now rather than on MySQL pattern matching.
1995 - Rewrote watchdog and submission throttle:
1996 * Improved watchdog messages and added watchdog filter.
1997 - Rewrote headline code and renamed it to import.module and export.module:
1998 * Added various improvements, including a better parser, bundles and better control over individual feeds.
1999 - Rewrote section code and renamed it to meta.module:
2000 * Supports unlimited amount of nested topics. Topics can be nested to create a multi-level hierarchy.
2001 - Rewrote configuration file resolving:
2002 * Drupal tries to locate a configuration file that matches your domain name or uses conf.php if the former failed. Note also that the configuration files got renamed from .conf to .php for security's sake on mal-configured Drupal sites.
2003 - Added caching support which makes Drupal extremely scalable.
2004 - Added access.module:
2005 * Allows you to set up 'roles' (groups) and to bind a set of permissions to each group.
2006 - Added blog.module.
2007 - Added poll.module.
2008 - Added system.module:
2009 * Moved most of the configuration options from hostname.conf to the new administration section.

2011 - Added statistics.module
2012 - Added moderate.module:
2013 * Allows to assign users editorial/moderator rights to certain nodes or topics.
2014 - Added page.module:
2015 * Allows creation of static (and dynamic) pages through the administration interface.
2016 - Added help.module:
2017 * Groups all available module documentation on a single page.
2018 - Added forum.module:
2019 * Added an integrated forum.
2020 - Added cvs.module and cvs-to-sql.pl:
2021 * Allows to display and mail CVS log messages as daily digests.
2022 - Added book.module:

2030 * Made the administration section only show those links a user has access to.
2031 * Made all modules use specific form_* functions to guarantee a rock-solid forms and more consistent layout.
2032 * Improved scheduler:
2033 + Content can be scheduled to be 'posted', 'queued' and 'hidden'.
2034 * Improved account module:
2035 + Added "access control" to allow/deny certain usernames/email addresses/hostnames.
2036 * Improved locale module:
2037 + Added new overview to easy the translation process.
2038 * Improved comment module:
2039 + Made it possible to permanently delete comments.

2050 Drupal 2.0.0, 2001-03-15
2051 ------------------------
2052 - Rewrote the comment/discussion code:
2053 * Comment navigation should be less confusing now.
2054 * Additional/alternative display and order methods have been added.
2055 * Modules can be extended with a "comment system": modules can embed the existing comment system without having to write their own, duplicate comment system.
2056 - Added sections and section manager:
2057 * Story sections can be maintained from the administration pages.
2058 * Story sections make the open submission more adaptive in that you can set individual post, dump and expiration thresholds for each section according to the story type and urgency level: stories in certain sections do not "expire" and might stay interesting and active as time passes by, whereas news-related stories are only considered "hot" over a short period of time.
2059 - Multiple vhosts + multiple directories:
2060 * You can set up multiple Drupal sites on top of the same physical source tree either by using vhosts or sub-directories.
2061 - Added "user ratings" similar to SlashCode's Karma or Scoop's Mojo:
2062 * All rating logic is packed into a module to ease experimenting with different rating heuristics/algorithms.
2063 - Added "search infrastructure":
2064 * Improved search page and integrated search functionality in the administration pages.
2065 - Added translation / localization / internationalization support:
2066 * Because many people would love to see their website showing a lot less of English, and far more of their own language, Drupal provides a framework to set up a multi-lingual website or to overwrite the default English text in English.
2067 - Added fine-grained user permission (or group) system:
2068 * Users can be granted access to specific administration sections. Example: a FAQ maintainer can be given access to maintain the FAQ and translators can be given access to the translation pages.
2070 - Changed the "open submission queue" into a (optional) module.
2072 * Improved account module:
2073 + User accounts can be deleted.
2074 + Added fine-grained permission support.
2075 * Improved block module
2076 * Improved diary module:
2077 + Diary entries can be deleted
2078 * Improved headline module:
2079 + Improved parser to support more "generic" RDF/RSS/XML backend.
2080 * Improved module module
2081 * Improved watchdog module
2082 * Improved database abstraction layer
2084 + W3C validation on a best effort basis
2085 + Added theme "example" (alias "Stone Age")
