 * Run client/maintenance/populateEntityUsage.php for all clients (not done, will do in ~january)

Changes

Changes

 * breaking change Changes to JavaScript data model. To access the main snak of a statement, it is now done with statement.getClaim.getMainSnak and qualifiers are accessed with statement.getClaim.getQualifiers.
 * Improved performance of lua (mw.wikibase.label and mw.wikibase.sitelink should not load the whole entity into memory)
 * Added irc url schema support for the url data type. (72924)
 * Allow submitting linkItem site link widget (in client) form with enter (72712) and move the linkItem dialog to the top (72687)
 * Use back-end parser for "commons" and "url".
 * Always show link to wikibase item in toolbox (e.g. in edit mode) in the client.
 * Adding Special:MergeItem as convenience alias for Special:MergeItems (68434)

Bug fixes

 * Fixed /re-added highlighting to siteselector and pagesuggester. (66433)

Deployment notes

 * Authority Control gadget needs updating and probably other gadgets.
 * need to bump $wgCacheEpoch (for parser cache)

Bug fixes

 * Check label/description constraint for new items 43734, 72085 and fix conflict detection. 71915

Bug fixes

 * Removed all usages of "class_alias" php method which were causing problems with hhvm. We should be able to re-enable the hhvm beta feature on Wikidata.
 * Various performance optimizations.
 * Don't show dead edit links in diff/old revisions. 72177
 * Display full year if precision is to high. 67604, 71289, 71956
 * Fix for edit conflict issue when editing multiple things in the "other languages" section. 72020
 * Fix entity deletion updates for properties, which cause problems like labels to not be removed from the wb_terms table, thus not allowing to create another property with that label. 71914

Other

 * Initial usage tracking code introduced (but not used yet). This includes a new table for client wikis, which can be created.

Deployment notes

 * We can create usage tracking table on client wikis. It is not used yet so no issue for it to be there and will be nice to have it there when we do introduce code that uses it.

Changes

 * Section editing for site link groups and "in other languages" instead of [edit] link for each individual site link, etc.

Bug fixes

 * Removed many usages of "class_alias" php method which doesn't work well in hhvm.

Other

 * Performance improvements for badges. (caching them in parser output)
 * Use Wikibase Data Model 1.0 in Wikibase. (should be nothing noticeable for users, but significant change in backend)
 * Refactoring and changes to javascript RepoApi.

Deployment notes

 * bump cache epoch for everywhere! (slow and gradually) and purge pages that use badges
 * bump cache epoch for wikidata
