Known issues

• This release has a known issue while setting -Ddd.logs.injection=true which was resolved in 0.61.0. We recommend users using this feature to update at least this version

Improvements

• Added support for new 0.5 endpoint included in the 7.22.0 datadog-agent release #1679
  • Add config to disable reporting to v0.5 endpoint. #1762

Changes

• Disable Hystrix tags by default to reduce data volume #1743
  • If you still want these tags, use -Ddd.hystrix.tags.enabled=true
• Add a config to disable thread pool executor instrumentation for all wrapped tasks #1752
• Out-of-Order Scope Close Handling #1739
• Move Config to internal-api #1734
  • This means Config is no longer published in dd-trace-api, but still available in dd-trace-ot. It should no longer be used though as it will be removed in a future release.
• Better linking for Haystack propagated traces #1691 #1728 (Thanks @aantono for the contribution!)

Fixes

• Make sure payloads are flushed on heavy volume of small traces #1766
• Add synchronization while adding dd tags to thread context(MDC) map #1758
• Fix grizzly host/port identification #1756
• allow context propagation for kafka tombstones #1754
• PrintingWriter fails on second trace #1738
• increase buffer size for v0.4 traces to avoid dropping large traces #1737
