0.42.53

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.

Changes

Behavior Changes

• 85fd41b - Do not cancel subscription on BlockingIterable#hasNext(long, TimeUnit) (#3128, #3154)
  • BlockingIterable#hasNext(long, TimeUnit) no longer cancels the subscription if the operation times out. This makes it consistent with the behavior of java.util.concurrent.Future.get(long, TimeUnit) and helps to preserve the stream for future use. However, this could result in resource leaks if the stream is not closed. We recommend using the try-with-resources pattern with blocking API's to avoid leaks.
• We've started using the dependency analysis plugin (#3158) which highlighted a number of dependency cleanups we could do. Some of those involved lowering dependency scope from api to implementation. Those shouldn't affect most users but in limited cases you may have been inadvertently getting a compile time dependency on a module transiently that didn't belong. In those cases you'll need to include the relevant module in your build.
