Automated section suggestions for the article Amedei in the recommendations testing tool (B). Also shown are the lead, existing sections (A), feedback form (C), and a template for providing specific feedback on-wiki (D).
The Wikimedia Research team is creating a new tool to suggest sections to add to articles. This could be useful for suggesting improvements new editors could make to stub articles. Machine learning would be used to recommend sections to add, based on what sections other similar articles have.
Before actually building the tool, the developers need to test the quality of the suggestions. Experienced editors can help by evaluating recommendations and providing feedback using the testing tool (instructions).
When you use rollback you will be able to get a confirmation prompt on most wikis. It asks you if you wanted to do the rollback. This is to avoid misclicks. You will have to opt in to get it. On German Wikipedia it will be an opt-out feature from 28 March. 
Admins will be able to block someone from editing a page or a namespace. This already works on a few Wikimedia wikis. You can read more. If your wiki wants to be an early tester of this, you can tell the developers. 
Toolforge will shut down the Ubuntu Trusty job grid. This will happen the week of 25 March. Tools that use this grid needs to be moved to the new Debian Stretch job grid. If they haven't, they will be taken offline. Maintainers can restart the tools later. Users may not be able to use them in the meanwhile. You can see a list of affected tools.
The new version of the content translation tool will be used for all new translations. The older version will still be used for translations that were started with it. Most users won’t see any change. More than 80% of the published translations are already using the new version. 
Editors who use Firefox to edit with the visual editor had a problem with copying text. When they tried to select text that included footnotes, templates or block images in the middle they would often only get part of the text. This has now been fixed. 
Wikis can over-ride interface messages on-wiki. A problem meant that sometimes an old versions of any changed messages were shown instead. This included the sitenotice and other important parts of the interface. This was fixed at around 2019-03-22 16:00 (UTC). Logged-out users may still get the wrong message. Purging the page should fix it for them. 
You can join the technical advice meeting on IRC. During the meeting, volunteer developers can ask for advice. The meeting takes place every Wednesday from 4:00–5:00 p.m. UTC. See how to join here.
