v4.3.0

What's Changed

• Improvements in tracing package:
  • Configurable Jaeger exporter to enable send via HTTP.
  • Remove logic that attempts to modify packet size.
    • This is an imperfect workaround when sending via UDP through network interface (instead of loopback) at standard MTU of 1500 bytes. This MTU is too small for many Jaeger spans, so some packets will still get dropped. Recommended to use HTTP export, instead.
• Implement syncutil.Broadcaster methods: Remove() and Has().
• Bugfixes in clock package.
