Latest *tech news https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News* from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/2017/15 are available.

*Recent changes*

- [image: Octicons-tools.svg] Tidy https://en.wikipedia.org/wiki/en:HTML_Tidy is going to be replaced with an HTML5 parsing algorithm. Bad HTML in wikitext would cause problems https://www.mediawiki.org/wiki/Parsing/Replacing_Tidy on a number of wikis. There is now a ParserMigration extension https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:ParserMigration on all wikis that you can use to help clean this up. You can read more about how you can use it https://www.mediawiki.org/wiki/Special:MyLanguage/Parsing/Replacing_Tidy#What_this_means_for_editors . [1] https://phabricator.wikimedia.org/T141586

*Changes this week*

- Some older web browsers https://en.wikipedia.org/wiki/en:Web_browser will not be able to use JavaScript https://en.wikipedia.org/wiki/en:JavaScript on Wikimedia wikis from this week. If you have an old web browser on your computer you can upgrade to a newer version. [2] https://phabricator.wikimedia.org/T128115 - New filters for Recent changes https://www.mediawiki.org/wiki/Special:MyLanguage/Edit_Review_Improvements/New_filters_for_edit_review will come to Wikidata and Persian, Russian, Turkish and French Wikipedia on 11 April. The schedule has been changed to fix the user intent prediction filters https://www.mediawiki.org/wiki/Special:MyLanguage/Help:New_filters_for_edit_review/Quality_and_Intent_Filters for some wikis. User intent prediction means the filter tries to make it easier for editors to determine if the edit was made in good faith or not. Other wikis will get it later https://phabricator.wikimedia.org/T146972. [3] https://phabricator.wikimedia.org/T158332 - The list of special characters in the wikitext editor and the visual editor will now have a group of Canadian Aboriginal characters. [4] https://phabricator.wikimedia.org/T108626 - [image: Octicons-sync.svg] The new version https://www.mediawiki.org/wiki/MediaWiki_1.29/wmf.20 of MediaWiki will be on test wikis and MediaWiki.org from 11 April. It will be on non-Wikipedia wikis and some Wikipedias from 12 April. It will be on all wikis from 13 April (calendar https://www.mediawiki.org/wiki/MediaWiki_1.29/Roadmap).

*Meetings*

- [image: Octicons-sync.svg] You can join the next meeting with the VisualEditor team. During the meeting, you can tell developers which bugs you think are the most important. The meeting will be on 11 April at 19:00 (UTC) http://www.timeanddate.com/worldclock/fixedtime.html?hour=19&min=00&sec=0&day=11&month=04&year=2017. See how to join https://www.mediawiki.org/wiki/VisualEditor/Weekly_triage_meetings.

*Future changes*

- Because of a data centre test you will be able to read but not edit the wikis for 20 to 30 minutes on 19 April and 3 May. This will start at 14:00 (UTC) http://www.timeanddate.com/worldclock/fixedtime.html?hour=14&min=00&sec=0&day=19&month=04&year=2017. You might lose edits if you try to save during this time. You can read more about this https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/Server_switch_2017 . - RevisionSlider https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:RevisionSlider will change how you move between revisions. This will be available on the test wiki https://test.wikipedia.org/wiki/Main_Page from 11 April. It will come to other wikis later if users like the change. You can test it and give feedback https://www.mediawiki.org/wiki/Extension_talk:RevisionSlider.
