@MrAlias Why drop support for go1.24. The reason is not clear, and maybe not that enough.
If using a lower version is OK, more old projects will benefit from your following updates.

See our compatibility policy: https://github.com/open-telemetry/opentelemetry-go?tab=readme-ov-file#compatibility
1.24 is not supported anymore. You won't get security fixes for it, you should upgrade.

Thank you very much.
