# Release Process
## Pre-Release
Update go.mod for submodules to depend on the new release which will happen in the next step.
1. Run the pre-release script. It creates a branch `pre_release_<new tag>` that will contain all release changes.
```
./pre_release.sh -t <new tag>
` ``
2. Verify the changes.
` ``
2021-02-28 18:08:33 -05:00
git diff main
2021-02-10 22:28:32 +01:00
` ``
This should have changed the version for all modules to be ` <new tag>`.
3. Update the [Changelog](./CHANGELOG.md).
- 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 bottom.
4. Push the changes to upstream and create a Pull Request on GitHub.
Be sure to include the curated changes from the [Changelog](./CHANGELOG.md) in the description.
## Tag
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.
***IMPORTANT***: [There is currently no way to remove an incorrectly tagged version of a Go module](https://github.com/golang/go/issues/34189).
It is critical you make sure the version you push upstream is correct.
[Failure to do so will lead to minor emergencies and tough to work around](https://github.com/open-telemetry/opentelemetry-go/issues/331).
2021-02-28 18:08:33 -05:00
1. Run the tag.sh script using the ` <commit-hash>` of the commit on the main branch for the merged Pull Request.
2021-02-10 22:28:32 +01:00
` ``
./tag.sh <new tag> <commit-hash>
` ``
2. 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>
...
` ``
## Release
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.
Additionally, the ` tag.sh` script generates commit logs since last release which can be used to supplement the release notes.
## Verify Examples
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.
## Contrib Repository
2021-02-28 18:08:33 -05:00
Once verified be sure to [make a release for the ` contrib` repository](https://github.com/open-telemetry/opentelemetry-go-contrib/blob/main/RELEASING.md) that uses this release.
