v1.29.0

🛑 Breaking changes 🛑

• vcs: Add the VCS metrics inspired by the GitHub Receiver (#1372)
  Makes the following changes:

  • Add metrics vcs.change.count, vcs.change.duration, vcs.change.time_to_approval, vcs.repository.count, vcs.ref.count,
    vcs.ref.lines_delta, vcs.ref.revisions_delta, vcs.ref.time, vcs.contributor.count
  • The VCS attributes vcs.change.state, vcs.revision_delta.direction and vcs.line_change.type have been added to the registry.
  • The VCS ref attributes have been duplicated to vcs.ref.base.* to allow for ref comparisons.
  • The VCS attribute vcs.ref.type has been added for simplicity when neither a full head or base ref is necessary.
  • vcs.repository.change.* attributes have been deprecated and moved to vcs.change.*.
  • vcs.repository.ref.* attributes have been deprecated and moved to vcs.ref.head.*.

• feature_flag: Rename feature_flag event to feature_flag.evaluation event, define new feature flag attributes and provide body definition. Remove feature_flag span event definition in favor of log-based event.

🧰 Bug fixes 🧰

• service: Merge resource experimental and stable groups for service and telemetry.sdk (#1423)
  Discovered when fixing weaver#306

• db: Fix telemetry for complex queries:

• introduce the db.query.summary attribute to provide a concise, low-cardinality
  representation of the query text.

• use db.query.summary as the span name and as a recommended attribute on metrics.

• avoid capturing db.operation.name and db.collection.name when the query
  involves multiple operations or collections, to prevent ambiguity.
  (#521, #805, #1159)

• url: Specific URL query string values should now be redacted by default due to concerns around leaking credentials. (#971)

• messaging: Fix typo in schemas for messaging attribute changes (#1595)
