Breaking changes

  • Support for 32-bit ARM builds is removed for the foreseeable future due to Go compiler issues. We will consider bringing back 32-bit ARM support once our Go compiler issues are resolved and 32-bit ARM builds are stable. (@​rfratto)

  • Agent Management: agent_management.api_url config field has been replaced by agent_management.host. The API path and version is now defined by the Agent. (@​jcreixell)

  • Agent Management: agent_management.protocol config field now allows defining "http" and "https" explicitly. Previously, "http" was previously used for both, with the actual protocol used inferred from the api url, which led to confusion. When upgrading, make sure to set to "https" when replacing api_url with host. (@​jcreixell)

  • Agent Management: agent_management.remote_config_cache_location config field has been replaced by agent_management.remote_configuration.cache_location. (@​jcreixell)

  • Remove deprecated symbolic links to to /bin/agent* in Docker containers, as planned in v0.31. (@​tpaschalis)

Bugfixes

  • Flow: fix issue where Flow would return an error when trying to access a key of a map whose value was the zero value (null, 0, false, [], {}). Whether an error was returned depended on the internal type of the value. (@​rfratto)

  • Flow: fix issue where using the jaeger_remote sampler for the tracing block would fail to parse the response from the remote sampler server if it used strings for the strategy type. This caused sampling to fall back to the default rate. (@​rfratto)

  • Flow: fix issue where components with no arguments like loki.echo were not viewable in the UI. (@​rfratto)

  • Flow: fix deadlock in loki.source.file where terminating tailers would hang while flushing remaining logs, preventing loki.source.file from being able to update. (@​rfratto)

  • Flow: fix deadlock in loki.process where a component with no stages would hang forever on handling logs. (@​rfratto)

  • Fix issue where a DefaultConfig might be mutated during unmarshaling. (@​jcreixell)

  • Fix issues where CloudWatch Exporter cannot use FIPS Endpoints outside of USA regions (@​aglees)

  • Fix issue where scraping native Prometheus histograms would leak memory. (@​rfratto)

  • Flow: fix issue where loki.source.docker component could deadlock. (@​tpaschalis)

  • Flow: fix issue where prometheus.remote_write created unnecessary extra child directories to store the WAL in. (@​rfratto)

  • Fix internal metrics reported as invalid by promtool's linter. (@​tpaschalis)

  • Fix issues with cri stage which treats partial line coming from any stream as same. (@​kavirajk @​aglees)

  • Operator: fix for running multiple operators with different --agent-selector flags. (@​captncraig)

  • Operator: respect FilterRunning on PodMonitor and ServiceMonitor resources to only scrape running pods. (@​captncraig)

  • Fixes a bug where the github exporter would get stuck in an infinite loop under certain conditions. (@​jcreixell)
