- The new Chef Server uses SOLR4 for faster search and reduced services for improved performance.
- Chef Client 12 adds SSL key verification by default, AIX support, and easier encrypted data bags among other features.
- The unified permissions system in Chef Server 12 breaks the ability to pre-seed nodes or inherit configurations that was possible in prior open source versions.
