Release Schedule

OpenTelemetry C++ is under active development.

The API and SDK packages are not yet generally available, and releases are not guaranteed to conform to a specific version of the specification. Future releases will not attempt to maintain backwards compatibility with previous releases. Each alpha and beta release could include significant changes to the API and SDK packages, making them incompatible with each other.

See the release notes for existing releases.

See the project milestones for details on upcoming releases. The dates and features described in issues and milestones are estimates, and subject to change.
