2.6.0

💥 Breaking Changes

• fix(resources): update OTEL_RESOURCE_ATTRIBUTES parsing to match spec changes (open-telemetry/opentelemetry-specification#4856) #6261 @JacksonWeber
  • Important: This fix is included in the "breaking changes" section because it can be breaking for some edge case usage of OTEL_RESOURCE_ATTRIBUTES:
    • export OTEL_RESOURCE_ATTRIBUTES=foo=bar,spam will now be fully ignored, because the spam entry is invalid (missing =). Per spec, any parsing error results in ignoring the entire environment variable.
    • export OTEL_RESOURCE_ATTRIBUTES='wat=" spaces "' will now result in {"wat": "\" spaces \""} with the double-quotes included in the value. Before this change the implementation included brittle double-quoting to allow leading and trailing whitespace in the value. To support leading or trailing whitespace now, you must percent-encode the whitespace. Internal whitespace still works without encoding, e.g. export OTEL_RESOURCE_ATTRIBUTES='green=eggs and ham'.
