# Release Process
|
||||
|
||||
This document outlines the process for releasing a new version of Cosmos SDK, which involves major release and patch releases as well as maintenance for the major release.
|
||||
|
||||
## Major Release Procedure
|
||||
|
||||
A _major release_ is an increment of the first number (eg: `v1.2` → `v2.0.0`) or the _point number_ (eg: `v1.1 → v1.2.0`, also called _point release_). Each major release opens a _stable release series_ and receives updates outlined in the [Major Release Maintenance](#major-release-maintenance)_section.
|
||||
|
||||
Before making a new _major_ release we do beta and release candidate releases. For example, for release 1.0.0:
|
||||
|
||||
```
|
||||
v1.0.0-beta1 → v1.0.0-beta2 → ... → v1.0.0-rc1 → v1.0.0-rc2 → ... → v1.0.0
|
||||
```
|
||||
|
||||
- Release a first beta version on the `master` branch and freeze `master` from receiving any new features. After beta is released, we focus on releasing the release candidate:
|
||||
- finish audits and reviews
|
||||
- kick off a large round of simulation testing (e.g. 400 seeds for 2k blocks)
|
||||
- perform functional tests
|
||||
- add more tests
|
||||
- release new beta version as the bugs are discovered and fixed.
|
||||
- After the team feels that the `master` works fine we create a `release/vY` branch (going forward known a release branch), where `Y` is the version number, with the patch part substituted to `x` (eg: 0.42.x, 1.0.x). Ensure the release branch is protected so that pushes against the release branch are permitted only by the release manager or release coordinator.
|
||||
- **PRs targeting this branch can be merged _only_ when exceptional circumstances arise**
|
||||
- update the GitHub mergify integration by adding instructions for automatically backporting commits from `master` to the `release/vY` using the `backport/Y` label.
|
||||
- In the release branch, prepare a new version section in the `CHANGELOG.md`
|
||||
- All links must be link-ified: `$ python ./scripts/linkify_changelog.py CHANGELOG.md`
|
||||
- Copy the entries into a `RELEASE_CHANGELOG.md`, this is needed so the bot knows which entries to add to the release page on GitHub.
|
||||
- Create a new annotated git tag for a release candidate (eg: `git tag -a v1.1.0-rc1`) in the release branch.
|
||||
- from this point we unfreeze master.
|
||||
- the SDK teams collaborate and do their best to run testnets in order to validate the release.
|
||||
- when bugs are found, create a PR for `master`, and backport fixes to the release branch.
|
||||
- create new release candidate tags after bugs are fixed.
|
||||
- After the team feels the release branch is stable and everything works, create a full release:
|
||||
- update `CHANGELOG.md`.
|
||||
- create a new annotated git tag (eg `git -a v1.1.0`) in the release branch.
|
||||
- Create a GitHub release.
|
||||
|
||||
Following _semver_ philosophy, point releases after `v1.0`:
|
||||
|
||||
- must not break API
|
||||
- can break consensus
|
||||
|
||||
Before `v1.0`, point release can break both point API and consensus.
|
||||
|
||||
## Patch Release Procedure
|
||||
|
||||
A _patch release_ is an increment of the patch number (eg: `v1.2.0` → `v1.2.1`).
|
||||
|
||||
**Patch release must not break API nor consensus.**
|
||||
|
||||
Updates to the release branch should come from `master` by backporting PRs (usually done by automatic cherry pick followed by a PRs to the release branch). The backports must be marked using `backport/Y` label in PR for master.
|
||||
It is the PR author's responsibility to fix merge conflicts, update changelog entries, and
|
||||
ensure CI passes. If a PR originates from an external contributor, a core team member assumes
|
||||
responsibility to perform this process instead of the original author.
|
||||
Lastly, it is core team's responsibility to ensure that the PR meets all the SRU criteria.
|
||||
|
||||
Point Release must follow the [Stable Release Policy](#stable-release-policy).
|
||||
|
||||
After the release branch has all commits required for the next patch release:
|
||||
|
||||
- update `CHANGELOG.md`.
|
||||
- create a new annotated git tag (eg `git -a v1.1.0`) in the release branch.
|
||||
- Create a GitHub release.
|
||||
|
||||
## Major Release Maintenance
|
||||
|
||||
Major Release series continue to receive bug fixes (released as a Patch Release) until they reach **End Of Life**.
|
||||
Major Release series is maintained in compliance with the **Stable Release Policy** as described in this document.
|
||||
Note: not every Major Release is denoted as stable releases.
|
||||
|
||||
Only the following major release series have a stable release status:
|
||||
|
||||
* **0.42 «Stargate»** is supported until 2022-02-09. A fairly strict **bugfix-only** rule applies to pull requests that are requested to be included into a stable point-release.
|
||||
* **0.44** is supported until 2022-07-17. A fairly strict **bugfix-only** rule applies to pull requests that are requested to be included into a stable point-release.
|
||||
* **0.45** is the latest major release and will be supported until 6 months after **0.46.0** release.
|
||||
|
||||
## Stable Release Policy
|
||||
|
||||
### Patch Releases
|
||||
|
||||
Once a Cosmos-SDK release has been completed and published, updates for it are released under certain circumstances
|
||||
and must follow the [Patch Release Procedure](CONTRIBUTING.md#patch-release-procedure)[Point Release Procedure].
|
||||
|
||||
### Rationale
|
||||
|
||||
Unlike in-development `master` branch snapshots, **Cosmos-SDK** releases are subject to much wider adoption,
|
||||
and by a significantly different demographic of users. During development, changes in the `master` branch
|
||||
affect SDK users, application developers, early adopters, and other advanced users that elect to use
|
||||
unstable experimental software at their own risk.
|
||||
|
||||
Conversely, users of a stable release expect a high degree of stability. They build their applications on it, and the
|
||||
problems they experience with it could be potentially highly disruptive to their projects.
|
||||
|
||||
Stable release updates are recommended to the vast majority of developers, and so it is crucial to treat them
|
||||
with great caution. Hence, when updates are proposed, they must be accompanied by a strong rationale and present
|
||||
a low risk of regressions, i.e. even one-line changes could cause unexpected regressions due to side effects or
|
||||
poorly tested code. We never assume that any change, no matter how little or non-intrusive, is completely exempt
|
||||
of regression risks.
|
||||
|
||||
Therefore, the requirements for stable changes are different than those that are candidates to be merged in
|
||||
the `master` branch. When preparing future major releases, our aim is to design the most elegant, user-friendly and
|
||||
maintainable SDK possible which often entails fundamental changes to the SDK's architecture design, rearranging and/or
|
||||
renaming packages as well as reducing code duplication so that we maintain common functions and data structures in one
|
||||
place rather than leaving them scattered all over the code base. However, once a release is published, the
|
||||
priority is to minimise the risk caused by changes that are not strictly required to fix qualifying bugs; this tends to
|
||||
be correlated with minimising the size of such changes. As such, the same bug may need to be fixed in different
|
||||
ways in stable releases and `master` branch.
|
||||
|
||||
### Migrations
|
||||
|
||||
To smoothen the update to the latest stable release, the SDK includes a set of CLI commands for managing migrations between SDK versions, under the `migrate` subcommand. Only migration scripts between stable releases are included. For the current major release, and later, migrations are supported.
|
||||
|
||||
### What qualifies as a Stable Release Update (SRU)?
|
||||
|
||||
* **High-impact bugs**
|
||||
* Bugs that may directly cause a security vulnerability.
|
||||
* *Severe regressions* from a Cosmos-SDK's previous release. This includes all sort of issues
|
||||
that may cause the core packages or the `x/` modules unusable.
|
||||
* Bugs that may cause **loss of user's data**.
|
||||
* Other safe cases:
|
||||
* Bugs which don't fit in the aforementioned categories for which an obvious safe patch is known.
|
||||
* Relatively small yet strictly non-breaking features with strong support from the community.
|
||||
* Relatively small yet strictly non-breaking changes that introduce forward-compatible client
|
||||
features to smoothen the migration to successive releases.
|
||||
* Relatively small yet strictly non-breaking CLI improvements.
|
||||
|
||||
### What does not qualify as SRU?
|
||||
|
||||
* State machine changes.
|
||||
* Breaking changes in Protobuf definitions, as specified in [ADR-044](./docs/architecture/adr-044-protobuf-updates-guidelines.md).
|
||||
* Changes that introduces API breakages (e.g. public functions and interfaces removal/renaming).
|
||||
* Client-breaking changes in gRPC and HTTP request and response types.
|
||||
* CLI-breaking changes.
|
||||
* Cosmetic fixes, such as formatting or linter warning fixes.
|
||||
|
||||
### What pull requests will be included in stable point-releases?
|
||||
|
||||
Pull requests that fix bugs and add features that fall in the following categories do not require a **Stable Release Exception** to be granted to be included in a stable point-release:
|
||||
|
||||
* **Severe regressions**.
|
||||
* Bugs that may cause **client applications** to be **largely unusable**.
|
||||
* Bugs that may cause **state corruption or data loss**.
|
||||
* Bugs that may directly or indirectly cause a **security vulnerability**.
|
||||
* Non-breaking features that are strongly requested by the community.
|
||||
* Non-breaking CLI improvements that are strongly requested by the community.
|
||||
|
||||
### What pull requests will NOT be automatically included in stable point-releases?
|
||||
|
||||
As rule of thumb, the following changes will **NOT** be automatically accepted into stable point-releases:
|
||||
|
||||
* **State machine changes**.
|
||||
* **Protobug-breaking changes**, as specified in [ADR-044](./docs/architecture/adr-044-protobuf-updates- guidelines.md).
|
||||
* **Client-breaking changes**, i.e. changes that prevent gRPC, HTTP and RPC clients to continue interacting with the node without any change.
|
||||
* **API-breaking changes**, i.e. changes that prevent client applications to *build without modifications* to the client application's source code.
|
||||
* **CLI-breaking changes**, i.e. changes that require usage changes for CLI users.
|
||||
|
||||
In some circumstances, PRs that don't meet the aforementioned criteria might be raised and asked to be granted a *Stable Release Exception*.
|
||||
|
||||
### Stable Release Exception - Procedure
|
||||
|
||||
1. Check that the bug is either fixed or not reproducible in `master`. It is, in general, not appropriate to release bug fixes for stable releases without first testing them in `master`. Please apply the label [v0.43](https://github.com/cosmos/cosmos-sdk/milestone/26) to the issue.
|
||||
2. Add a comment to the issue and ensure it contains the following information (see the bug template below):
|
||||
|
||||
* **[Impact]** An explanation of the bug on users and justification for backporting the fix to the stable release.
|
||||
* A **[Test Case]** section containing detailed instructions on how to reproduce the bug.
|
||||
* A **[Regression Potential]** section with a clear assessment on how regressions are most likely to manifest as a result of the pull request that aims to fix the bug in the target stable release.
|
||||
|
||||
3. **Stable Release Managers** will review and discuss the PR. Once *consensus* surrounding the rationale has been reached and the technical review has successfully concluded, the pull request will be merged in the respective point-release target branch (e.g. `release/v0.43.x`) and the PR included in the point-release's respective milestone (e.g. `v0.43.5`).
|
||||
|
||||
#### Stable Release Exception - Bug template
|
||||
|
||||
```
|
||||
#### Impact
|
||||
|
||||
Brief xplanation of the effects of the bug on users and a justification for backporting the fix to the stable release.
|
||||
|
||||
#### Test Case
|
||||
|
||||
Detailed instructions on how to reproduce the bug on Stargate's most recently published point-release.
|
||||
|
||||
#### Regression Potential
|
||||
|
||||
Explanation on how regressions might manifest - even if it's unlikely.
|
||||
It is assumed that stable release fixes are well-tested and they come with a low risk of regressions.
|
||||
It's crucial to make the effort of thinking about what could happen in case a regression emerges.
|
||||
```
|
||||
|
||||
### Stable Release Managers
|
||||
|
||||
The **Stable Release Managers** evaluate and approve or reject updates and backports to Cosmos-SDK Stable Release series,
|
||||
according to the [stable release policy](#stable-release-policy) and [release procedure](#stable-release-exception-procedure).
|
||||
Decisions are made by consensus.
|
||||
|
||||
Their responsibilites include:
|
||||
|
||||
* Driving the Stable Release Exception process.
|
||||
* Approving/rejecting proposed changes to a stable release series.
|
||||
* Executing the release process of stable point-releases in compliance with the [Point Release Procedure](CONTRIBUTING.md).
|
||||
|
||||
The Stable Release Managers are appointed by the Interchain Foundation. Currently residing Stable Release Managers:
|
||||
|
||||
* @clevinson - Cory Levinson
|
||||
* @amaurym - Amaury Martiny
|
||||
* @robert-zaremba - Robert Zaremba
