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 at MediaWiki core deployments starting in April, and how that might work. 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.
