[chef] Where to go for Chef release notes?

[< >]

I googled for "chef release notes" and the first result that came up doesn't
appear to have been updated in awhile:

https://wiki.opscode.com/display/chef/Release+Notes

The next link on the search results seems to have more up to date information,
but I don't see anything about previous releases on this page:

http://docs.opscode.com/release_notes.html

I also found some other links on github:

https://github.com/opscode/chef/blob/11-stable/CHANGELOG.md
https://github.com/opscode/chef/blob/master/CHANGELOG.md
https://github.com/opscode/chef/blob/master/RELEASE_NOTES.md

Where's the right place to go to find out what changes went into a release? 
For
example, how can I find out what changed between 11.10.0-1, 11.10.2-1, and
11.10.4-1?
