# Boxo Releases | ||
|
||
## Release Policies | ||
### Breaking Changes | ||
TLDR: APIs may break between changes. | ||
|
||
There are two kinds of breaking changes to consider: | ||
|
||
1. **API refactors/changes**. There is equivalent functionality, but the API has changed. Generally adapting to these changes is trivial, and release notes will contain information about how to adapt. | ||
|
||
1. **Removal of a module or functionality**. In this case, Boxo maintainers will deprecate the relevant types in at least one release prior to their removal, and users will be forewarned in release notes. We strive to remove functionality as rarely as possible. | ||
|
||
We know that breaking changes may cause short-term pain, and we only make breaking changes when we believe the long-term gain is much greater than the short-term pain. | ||
|
||
Feedback from users helps us in this determination, so *please* provide feedback on any GitHub issues or PRs that may affect you, and let us know when we're wrong! We believe there's *a lot* of innovation and growth for IPFS in the future, so we don't want Boxo to ossify. | ||
|
||
### Versioning | ||
Boxo only releases minor and patch versions, and has no plans to change major versions from v0. | ||
|
||
Minor versions contain new or removed functionality, or significant changes in dependencies. | ||
|
||
Patch versions contain "fixes", which are generally small, targeted, and involve limited changes in functionality (such as bug fixes, security fixes, etc.). The amount of backporting depends on the severity of the issue and the impact on users...most non-critical fixes won't be backported. | ||
|
||
As a result, Boxo maintainers recommend that consumers stay up-to-date with Boxo releases. | ||
|
||
### Go Compatibility | ||
At any given point, the Go team supports only the latest two versions of Go released (see https://go.dev/doc/devel/release). Boxo maintainers will strive to maintain compatibilty with the older of the two supported versions, so that Boxo is also compatible with the latest two versions of Go. | ||
|
||
### Release Criteria | ||
Boxo releases occur _at least_ on every Kubo release. Releases can also be initiated on-demand, regardless of Kubo's release cadence, whenever there are significant changes (new features, refactorings, deprecations, etc.). | ||
|
||
The [release process](#release-process) below describes how maintainers perform a release. | ||
|
||
Boxo may release on Fridays or even weekends. This is in contrast to Kubo, which does not release on Fridays since it is a deployable binary, to avoid weekend surprises. | ||
|
||
### Testing | ||
Boxo maintainers are in the process of moving tests into Boxo from Kubo (see [#275](https://github.com/ipfs/boxo/issues/275)) . Until that's done, Boxo releases rely on Kubo tests for extra confidence. So releases must plumb Boxo into Kubo and ensure its tests pass. See [Release Process](#release-process) for details. | ||
|
||
### Changelogs | ||
Boxo loosely follows the [Keep a Changelog](https://keepachangelog.com/en/1.0.0/) format. New commits should add changelog entries into the `[Unreleased]` section so that there is no changelog scramble when a new version needs to be released. | ||
|
||
We intend to use the standardized changelog to automate releases by onboarding with [Changelog Driven Release](https://github.com/pl-strflt/changelog-driven-release) (see [#269](https://github.com/ipfs/boxo/issues/269)). | ||

|
||
## Release Process | ||
1. Create an issue for the version: https://github.com/ipfs/boxo/issues/new?title=Release+X.Y.Z (can be blank for now) | ||
2. Pin the issue | ||
3. Copy-paste the following checklist into the description: | ||
|
||
- [ ] Verify your [GPG signature](https://docs.github.com/en/authentication/managing-commit-signature-verification) is configured in local git and GitHub | ||
- [ ] Ensure Boxo and Kubo are checked out on your system | ||
- [ ] Create a release branch called `release-vX.Y.Z` and push it | ||
* Use `master` as base if `Z == 0` | ||
* Use `release` as base if `Z > 0` | ||
- [ ] Tidy the changelog and push any changelog changes to `release-vX.Y.Z` | ||
- [ ] Create a draft PR merging `release-vX.Y.Z` into `release` | ||
- [ ] Name it "Release vX.Y.Z" | ||
- [ ] Reference this release issue | ||
- [ ] If `Z > 0`, then cherry-pick the necessary commits from `master` into `release-vX.Y.Z` using `git cherry-pick -x <commit>` | ||
- [ ] Ensure Boxo tests are passing | ||
- [ ] Ensure Kubo tests are passing | ||
- [ ] Go to Kubo dir and run `go get github.com/ipfs/boxo@<commit_hash>` using the commit hash of the `release-vX.Y.Z` branch | ||
- [ ] Run `go mod tidy` in repo root and in `docs/examples/kubo-as-a-library` | ||
- [ ] Commit the changes and open a draft PR in Kubo | ||
- [ ] Name the PR "Upgrade to Boxo vX.Y.Z" | ||
- [ ] Paste a link to the Kubo PR in the Boxo PR, so reviewers can verify the Kubo test run | ||
- [ ] Verify the CI passes | ||
- [ ] Add a commit in `release-vX.Y.Z` bumping the version in `version.json` to `vX.Y.Z` | ||
- [ ] Add a "release" label to the Boxo PR | ||
- [ ] After the release checker creates a draft release, copy-paste the changelog into the draft | ||
- [ ] Wait for approval from another Boxo maintainer | ||
- [ ] Merge the PR into `release`, _using "Create a Merge Commit"_, and do not delete the `release-vX.Y.X` branch | ||
- [ ] Verify the tag is created | ||
- [ ] Announce the release | ||
- [ ] Create an [IPFS Discourse](https://discuss.ipfs.tech) topic | ||
- [ ] use `Boxo vX.Y.Z is out!` as the title | ||
- [ ] use `boxo` as the topic | ||
- [ ] repeat the title as a heading (`##`) in the description | ||
- [ ] link to the GitHub Release and release notes in the description | ||
- [ ] Create a PR merging `release` into `main` | ||
- [ ] Name it "Merge release vX.Y.Z" | ||
- [ ] Wait for approval | ||
- [ ] Merge it _using "Create a Merge Commit"_, and do not delete the `release` branch | ||
- [ ] Update the Kubo PR to use the newly released version, mark it as "Ready for Review", get approval, and merge into Kubo |
