  • Tail-based sampling: Fix missing or infrequent monitoring metric lsm_size and value_log_size (#17512)
  • Fix default tracer http request sent to https endpoint error when both self-instrumentation and TLS are enabled (#17293)
  • Tail-based sampling: Optimize performance for instances with more CPU and memory (#17254)
  • Tail-based sampling: Fix ever-increasing dynamic group count monitoring metric (#17042)
  • Tail-based sampling: Fix incorrectly large pebble database lsm_size monitoring metric in edge cases which causes TBS to be bypassed (#17149)
  • Tail-based sampling: Log pubsub errors at error or warn level (#17135)
  • Fix missing trusted root certificate authority in the docker image (#16928)
  • Tail-based sampling: ignore subscriber position read error and proceed as if file does not exist to avoid crash looping (#16736)
  • Tail-based sampling: Storage layer is rewritten to use Pebble database instead of BadgerDB. The new implementation offers a substantial throughput increase while consuming significantly less memory. Disk usage is significantly lower and more stable. See APM Transaction sampling docs for benchmark details. (#15235)
  • Fix overflow in validation of apm-server.agent.config.cache.expiration on 32-bit architectures. (#15216)
  • Change permissions of apm-server.yml in tar.gz artifacts to 0600. (#15627)
