Summarized list of changes:
Bryan McLellan added FreeBSD package and service providers, making Chef available to FreeBSD users!
Because he is a machine, Bryan also added Cron and Route support.
Gentoo Portage support was dramatically improved, thanks to Ezra and Tim Dysinger.
Because it confused everyone who used it, we changed the way you specify Link resources. The new syntax is:
link "/tmp/somefile" do to "/etc/passwd" end
Make sure you update any recipes that are using Link before the 0.5.2 upgrade!
We fixed an irritating bug where badly behaved children would force Chef to block forever trying to read their STDOUT or STDERR – if you’ve been having issues with Chef hanging (particularly calling things like Red Hat init scripts) they are no longer an issue with 0.5.2.
Speaking of Init Scripts, Lee Jensen added support for Gentoo services management, and I added one for Red Hat (and its derivatives).
AJ wrangled the Group Provider in to shape – you can now add group members properly. He also did a huge number of bug fixes. Thanks AJ!
All this and more are in Chef 0.5.2! Take a look at the Changelog for full details.
EC2 meta-data is now available through Ohai. Thanks to Ben Black, Tim Dysinger, and Ezra.
Paul Nasrat helped track down a bug in our test suite that was causing false errors. Thanks, Paul – your a life-saver.
FreeBSD attributes are now available in Ohai (Bryan McLellan).
OpenSolaris attributes are now available in Ohai.
Per-Interface ARP tables are now available in Ohai.
