MediaWiki 1.20/Roadmap

Deployments of 1.20 versions were very different from past deployments. We started deploying very regularly (targeting 2-week cycles), with longer stretches (e.g. 6 months) between publishing releases of the installer for third-party users. Read more. Deployment of 1.20 is now finished as we've moved on to 1.21, and volunteers are now leading the way on the tarball release.
