v3.1.0

3.1.0

🚀 Features

• feat(resources): Deprecate envDetector in favor of separate resourceAttributesEnvDetector and serviceNameEnvDetector. Also mark serviceInstanceIdDetector as stable (the service.instance.id semconv attribute is now stable). #6999 @trentm

🐛 Bug Fixes

• fix(context-zone): declare the @opentelemetry/api peer dependency so Yarn PnP can resolve it for context-zone-peer-dep #7268 @Vivek1898
• fix(core): accept attribute values with shared (non-circular) object references #7068 @rajanpanth
• fix: raise the minimum @opentelemetry/api peer dependency version to 1.10.0 for packages that depend on @opentelemetry/core, @opentelemetry/otlp-transformer or @opentelemetry/instrumentation, as these use API 1.10 features. (#7258) @volodymyrshk @pichlermarc
  • Combining these packages with @opentelemetry/api 1.9.x never worked: they failed at runtime. The peer dependency now makes npm report this at install time instead.
  • If you see a peer dependency error after upgrading, update @opentelemetry/api to 1.10.0 or later.
• fix(propagator-b3): reject trace ids that are not 16 or 32 characters long #7262 @adityareddy-dev
