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/2017/16 are available.

*Recent changes*

- You can add ?safemode=1 to the end of the URL on Wikimedia wikis to disable your personal CSS https://en.wikipedia.org/wiki/en:Cascading_Style_Sheets and JavaScript https://en.wikipedia.org/wiki/en:JavaScript. Example: https://en.wikipedia.org/wiki/Literature?safemode=1. This means you can test if a problem is because of your user scripts or gadgets without uninstalling them. [1] https://phabricator.wikimedia.org/T152169 - You can now see a list of all autoblocks on Special:AutoblockList https://meta.wikimedia.org/wiki/Special:AutoblockList. [2] https://phabricator.wikimedia.org/T146414 - [image: Octicons-tools.svg] The Wikiversity and Wikinews logos are now shown directly from the configuration and not from [[File:Wiki.png]]. If you want to change logo or have an anniversary logo, see how to request a configuration change https://meta.wikimedia.org/wiki/Special:MyLanguage/Requesting_wiki_configuration_changes. This is how it already works for other projects. They can request logo changes the same way. [3] https://phabricator.wikimedia.org/T161980

*Problems*

- 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. 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. This will also happen on 3 May.

*Changes this week*

- There is no new Mediawiki version this week. This is because of the data centre test.

*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 18 April at 19:00 (UTC) http://www.timeanddate.com/worldclock/fixedtime.html?hour=19&min=00&sec=0&day=18&month=04&year=2017. See how to join https://www.mediawiki.org/wiki/VisualEditor/Weekly_triage_meetings.

*Future changes*

- stats.wikimedia.org will be replaced. You can see the new prototype https://analytics-prototype.wmflabs.org/#/. You can leave feedback on this change https://www.mediawiki.org/wiki/Talk:Wikistats_2.0_Design_Project/RequestforFeedback/Round2 . - Page Previews https://www.mediawiki.org/wiki/Beta_Features/Hovercards will be turned on for logged-out users on a large number of wikis in May. It could be postponed and happen later. Page Previews shows readers a short part of a linked article when they rest their mouse pointer on the link. This is to help them understand what it is about without leaving the article they are reading. Page Previews used to be called Hovercards. Users who have tested the feature can give feedback https://www.mediawiki.org/wiki/Talk:Beta_Features/Hovercards. [4] https://meta.wikimedia.org/wiki/Special:MyLanguage/User:CKoerner_%28WMF%29/Enable_Hovercards/Phase_1 - [image: Octicons-tools.svg] From next week, user scripts using very old deprecated https://en.wikipedia.org/wiki/en:Deprecation#Software_deprecation wikibits functions will show errors. These functions have not worked since 2013. You should fix or disable broken scripts. You can see examples of how to upgrade scripts https://www.mediawiki.org/wiki/Special:MyLanguage/ResourceLoader/Legacy_JavaScript#wikibits.js.
