[0.2.2] - 2026-06-09
Added
- added finite HTTP request and connection timeouts for OTLP metrics export
- added support for
OTEL_EXPORTER_OTLP_TIMEOUTandOTEL_EXPORTER_OTLP_METRICS_TIMEOUT
Fixed
- aligned the default OTLP export timeout with the standard
10_000millisecond value - treated a timeout value of
0as 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_valuemetrics so old telemetry handlers do not crash and detach after a bridge restart
[0.2.0] - 2026-06-01
Added
- added
Telemetry.Metrics.LastValuesupport through OpenTelemetry observable gauges - added
last_valuecardinality controls::ttl_ms,:max_series, and:on_overflow - expanded docs and the basic example with a bounded queue-depth
last_valuemetric
Changed
- relaxed the
telemetry_metricsdependency to support both~> 0.6and~> 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

source_url, maintainer, and package links metadata - added
ex_docas the documentation dependency for local and HexDocs builds
