New versions of the [OpenTelemetry Semantic Conventions] mean new versions of the `semconv` package need to be generated. The `semconv-generate` make target is used for this. Checkout a local copy of the [OpenTelemetry Semantic Conventions] to the desired release tag. Pull the latest `otel/semconvgen` image: `docker pull otel/semconvgen:latest` Run the `make semconv-generate ...` target from this repository. For example, ```sh export TAG="v1.21.0" # Change to the release version you are generating. export OTELSEMCONVREPO="/absolute/path/to/opentelemetry/semantic-conventions" docker pull otel/semconvgen:latest make semconv-generate # Uses the exported TAG and OTELSEMCONVREPO. ``` This should create a new sub-package of . Ensure things look correct before submitting a pull request to include the addition. You can run `make gorelease` that runs to ensure that there are no unwanted changes done in the public API. You can check/report problems with `gorelease` . First, decide which module sets will be released and update their versions in `versions.yaml`. Commit this change to a new branch. Update go.mod for submodules to depend on the new release which will happen in the next step. Run the `prerelease` make target. It creates a branch `prerelease<module set><new tag>` that will contain all release changes. ``` make prerelease MODSET=<module set> ``` Verify the changes. ``` git diff ...prerelease<module set><new tag> ``` This should have changed the version for all modules to be `<new tag>`. If these changes look correct, merge them into your pre-release branch: ```go git merge prerelease<module set><new tag> ``` Update the . Make sure all relevant changes for this release are included and are in language that non-contributors to the project can understand. To verify this, you can look directly at the commits since the `<last tag>`. ``` git --no-pager log --pretty=oneline "<last tag>..HEAD" ``` Move all the `Unreleased` changes into a new section following the title scheme (`[<new tag>] - <date of release>`). Update all the appropriate links at the

Push the changes to upstream and create a Pull Request on GitHub. Be sure to include the curated changes from the in the description. Once the Pull Request with all the version changes has been approved and merged it is time to tag the merged commit. *IMPORTANT*: It is critical you use the same tag that you used in the Pre-Release step! Failure to do so will leave things in a broken state. As long as you do not change `versions.yaml` between pre-release and this step, things should be fine. *IMPORTANT*: . It is critical you make sure the version you push upstream is correct. . For each module set that will be released, run the `add-tags` make target using the `<commit-hash>` of the commit on the main branch for the merged Pull Request. ``` make add-tags MODSET=<module set> COMMIT=<commit hash> ``` It should only be necessary to provide an explicit `COMMIT` value if the current `HEAD` of your working directory is not the correct commit. Push tags to the upstream remote (not your fork: `github.com/open-telemetry/opentelemetry-go.git`). Make sure you push all sub-modules as well. ``` git push upstream <new tag> git push upstream <submodules-path/new tag> ... ``` Finally create a Release for the new `<new tag>` on GitHub. The release body should include all the release notes from the Changelog for this release. After releasing verify that examples build outside of the repository. ``` ./verify_examples.sh ``` The script copies examples into a different directory removes any `replace` declarations in `go.mod` and builds them. This ensures they build with the published release, not the local copy. Once verified be sure to that uses this release. Update the [Go instrumentation documentation] in the OpenTelemetry website under [content/en/docs/languages/go]. Importantly, bump any package versions referenced to be the latest one you just released and ensure all code examples still compile and are accurate. Bump the dependencies in the following Go services:
