Hey all,
This is a quick note that the "Your edit was saved" confimration message ( http://www.mediawiki.org/wiki/Confirmation_message) was added to MediaWiki core. We plan to deploy it later this week.
This message was previously contained in Extension:PostEdit, and was deployed to several dozen projects. For projects that already have it, nothing should change. For those that don't, you may need to localize the one message string.
For context: this feature was merged in to core in order to support delivery of an identical message for those using VisualEditor, per bug 48276.
