@trask - I'm working on this PR locally (FYI).

Issues I'm facing now:

• https://github.com/open-telemetry/semantic-conventions/pull/1807/files#r1929158623

What should I use instead of /docs/specs/otel/logs/api/#emit-an-event now that #emit-an-event no longer exists?

Will be replacing it with #emit-a-logrecord per discussion with @trask on Slack.

Another issue:

• [editorial] Alias needs to be changed for renamed docs file semantic-conventions#1815

[chalin]

Latest commit adds a local patch equivalent of:

• [editorial] Set alias of semantic-convention-groups.md to group-stabi… semantic-conventions#1816

[chalin]

All checks are passing now.

thanks!
