Recent software changes
(Not all changes will affect you.)
The latest version of MediaWiki (1.22/wmf5) was added to non-Wikipedia wikis on May 29. It will be enabled on the English Wikipedia on June 3, and on all other Wikipedias on June 5. 
The Tamil Wikipedia shared a Lua module they created to automate their Main Page. 
There is now a test wiki to test new features in right-to-left languages. 
The Thanks feature was added to the English Wikipedia; users can now thank others for individual edits. 
The new interface for account creation and log-in is now the default on 30 wikis, including the English Wikipedia, Commons, Meta, and Wikidata. The feature will be added to all wikis after June 5. Users can return to the old look by adding ?useNew=0 to the web address. 
Videos are now played in pop-up windows if their size on the page is smaller than 200 pixels (800 pixels on the English Wikipedia). 
The new Disambiguator extension, which was previously part of MediaWiki itself, was enabled on test wikis. It adds the magic word __DISAMBIG__ to mark disambiguation pages. 
The newly enabled Campaigns extension allows Wikimedia Foundation data analysts to track account creations that result from a specific outreach campaign.
Future software changes
Universal Language Selector will be added to the Catalan (ca), Cebuano (ceb), Persian (fa), Finnish (fi), Norwegian Bokmål (no), Portuguese (pt), Ukrainian (uk), Vietnamese (vi), Waray-Waray (war) and Chinese (zh) Wikipedias on June 18. 
Starting on June 18, VisualEditor will be randomly enabled by default for half of newly created accounts on the English Wikipedia to test stability, performance and features. 
Two new webfonts (UnifrakturMaguntia and Linux Libertine) will be added to wikis that use Universal Language Selector. 
It will now be possible to hide the sidebar while using the Translate extension to reduce distractions (bug #45836).
