Version 1.42.1/0.63b1 (2026-05-21)

Added

• opentelemetry-api, opentelemetry-sdk: add support for 'random-trace-id' flags in W3C traceparent header trace flags. Implementations of IdGenerator that do randomly generate the 56 least significant bits, should also implement a is_trace_id_random methods that returns True. (#4854)

[Eduard van Valkenburg (eavanvalkenburg)]

Closing in favor of #6238. opentelemetry-sdk cannot be bumped to 1.42.1 while azure-monitor-opentelemetry (including the latest 1.8.8) hard-pins opentelemetry-sdk==1.40 — the resolution is unsatisfiable. #6238 keeps opentelemetry-sdk at 1.40.0 and documents this; a bump requires a compatible azure-monitor-opentelemetry release first.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
