This patch release fixes a bug when using default values that was introduced by 3.3.0 and adds some missing labels. People who haven't already upgraded to 3.3.0 should go directly to this release when they are ready to upgrade, and we recommend upgrading to 3.3.1 if you have already upgraded to 3.3.0 and use or plan to use default values for record creation.
See the 3.3.0 release notes for the full listing of new functionality and fixes in the 3.3 releases.
