The engineering team is busy working on the deployment of the 1.17 branch of MediaWiki. We plan to roll this out next week to all languages and projects, Tuesday, February 8, with work starting at 07:00 UTC (which is 11pm on Monday, February 7 for San Francisco).
If all goes well, you should only notice the improvement. If it doesn’t go well, that’s because there’s something we missed, and that’s where we’d love your help. Please help us test this release! We have a test instance of the software we plan to deploy available at prototype.wikimedia.org. If you find issues, please report them in Bugzilla.
Note that this isn’t a release for download, yet. On and after February 8, the “latest” version of MediaWiki will still be 1.16 as listed on mediawiki.org. We plan to update this to 1.17 sometime after the deployment of the 1.17 branch, after we’ve had time to run it in production for a while and fix the issues we’re likely to find.
So please, help us test this release, and if you find bugs, please report them in Bugzilla. Thanks!
