Recent changes

On Wikidata, the "save" button when you edit is now called "publish". This means all Wikimedia wikis have now changed from "Save page" to "Publish changes". This is to help new editors understand what it does. [1][2]
Some edits will get an automatic tag on all wikis. This will happen when making a page a redirect, blanking a page, removing almost all content, undoing an edit, or rolling back an edit. You can see the tags for example in the recent changes feed, article history, user contributions or on your watchlist. Some wikis had already marked edits like these in other ways. [3]
Special:UnusedFiles shows files that have been uploaded but are not used. It will show a file that is not used on the wiki it has been uploaded to, even if the file is used on another wiki. The new Special:GloballyUnusedFiles page on Commons only shows files that are not used on any wiki. [4]
Structured discussions now uses the 2017 wikitext editor instead of its old custom one. This will work with your preference for wikitext or visual editor. The documentation has been updated. [5][6]

Problems

Older versions of the Chrome web browser on mobile devices may see the PDF download button, but it does not work. The developers are looking into the problem. [7]
With the new filters in the recent changes, "Exclude selected" in "Namespaces" did not work for "Saved filters" between 13 December and 2 January. When you loaded the saved filter all other namespaces were excluded instead. This has now been fixed. If you made any changes to your saved filters between 13 December and 2 January, you need to save your filters with excluded namespaces again. [8]
The latest version of Google Chrome broke how section links are shown in the address bar. You now see #R%C3%A9sum%C3%A9 instead of #Résumé even if MediaWiki did not encode it that way. This happened in early December. This problem has been solved. The fix will be in Chrome 64 (23 January) or Chrome 65 (6 March). [9]
Some POST requests to the API took longer than usual in parts of December. This affected the Wikidata UI and some gadgets the most. It has now been fixed. [10]

Changes later this week

Wikidata will be moved to its own database servers. This is because it is growing and needs more resources. Because of this you will be able to read but not editWikidata and the German Wikipedia between 06:00 and 06:30 UTC on 9 January. You might lose edits if you try to save during this time. This includes editing the language links on other wikis. [11]
The font size in the editing window will change slightly for some users. It will now look the same on all browsers and operating systems. [12][13]
The new version of MediaWiki will be on test wikis and MediaWiki.org from 9 January. It will be on non-Wikipedia wikis and some Wikipedias from 10 January. It will be on all wikis from 11 January (calendar).
WikiEditor's ResourceLoader modules have been simplified to one: ext.wikiEditor. All the other modules are now deprecated aliases and should be removed. [14]
