Is there public ST2 changelog provided? I would like to stay up to date with all new , cool features implemented in PR2 and upcoming releases.
EDIT: Ohh... Release notes are sticked on the top :/ I've searched everywhere, but not there.
Inside every Sencha product release there is a file called "release-notes.html".
You can find a complete change log inside that file.
Hope this helps.
The next release will also provide a clear link on the main page.
