[0.2.3] - 2026-06-10

Fixed

  • fixed HTTP protobuf metrics export request types so :httpc accepts the OTLP Content-Type and gzip Content-Encoding fields

[0.2.2] - 2026-06-09

Added

  • added finite HTTP request and connection timeouts for OTLP metrics export
  • added support for OTEL_EXPORTER_OTLP_TIMEOUT and OTEL_EXPORTER_OTLP_METRICS_TIMEOUT

Fixed

  • aligned the default OTLP export timeout with the standard 10_000 millisecond value
  • treated a timeout value of 0 as no limit and ignored invalid environment values with a warning instead of failing exporter initialization
  • capped the HTTP connection timeout at the total export timeout

[0.2.1] - 2026-06-02

Fixed

  • ignored stale ETS table references while recording last_value metrics so old telemetry handlers do not crash and detach after a bridge restart

[0.2.0] - 2026-06-01

Added

  • added Telemetry.Metrics.LastValue support through OpenTelemetry observable gauges
  • added last_value cardinality controls: :ttl_ms, :max_series, and :on_overflow
  • expanded docs and the basic example with a bounded queue-depth last_value metric

Changed

  • relaxed the telemetry_metrics dependency to support both ~> 0.6 and ~> 1.0

[0.1.2] - 2026-05-30

Changed

  • rewrote the README and primary module docs to introduce the library from problem statement through integration flow
  • added a lightweight architecture diagram and explicit metric mapping reference for the Telemetry-to-OpenTelemetry bridge
  • improved module reference docs for OtelBridge, specs, profiles, and runtime internals with more consistent wording and onboarding guidance
  • simplified ExDoc navigation by showing full module names instead of nested prefix shorthands

[0.1.1] - 2026-05-30

Changed

  • expanded HexDocs coverage across all library modules
  • documented public API functions, profiles, runtime modules, and behaviours
  • improved HexDocs navigation with module grouping and nested namespaces
  • added source_url, maintainer, and package links metadata
  • added ex_doc as the documentation dependency for local and HexDocs builds

[0.1.0] - 2026-05-30
