This is a minor maintenance release appropriate for all ServiceTalk users that contains several useful improvements and bug fixes. This release is expected to be a "drop-in" replacement for all prior 0.42.X releases.

As the ServiceTalk API advances towards a 1.0 release all users are strongly encouraged to update their applications to eliminate all use of deprecated APIs. Existing deprecated APIs will be removed in a future ServiceTalk release without further additional notice. If you encounter problems replacing deprecated usages please create a support issue.
