# Release instructions
## Pre-release checks
These should run successfully:
* `make all`;
* `make test`;
* `make lint` (should not change any files);
* `make fmts` (should not change any files);
* `go mod tidy` (should not change any files);
* integration tests in [neofs-devenv](https://github.com/nspcc-dev/neofs-devenv).
## Make release commit
Use `vX.Y.Z` tag for releases and `vX.Y.Z-rc.N` for release candidates
following the [semantic versioning](https://semver.org/) standard.
Determine the revision number for the release:
```shell
$ export NEOFS_REVISION=X.Y.Z[-rc.N]
$ export NEOFS_TAG_PREFIX=v
```
Double-check the number:
```shell
$ echo ${NEOFS_REVISION}
```
Create release branch from the main branch of the origin repository:
```shell
$ git checkout -b release/${NEOFS_TAG_PREFIX}${NEOFS_REVISION}
```
### Update versions
Write new revision number into the root `VERSION` file:
```shell
$ echo ${NEOFS_TAG_PREFIX}${NEOFS_REVISION} > VERSION
```
Update the supported version of `nspcc-dev/neofs-contract` module in root
`README.md` if needed.
### Writing changelog
Add an entry to the `CHANGELOG.md` following the style established there.
* copy `Unreleased` section (next steps relate to section below `Unreleased`)
* replace `Unreleased` link with the new revision number
* update `Unreleased...new` and `new...old` diff-links at the bottom of the file
* add optional codename and release date in the heading
* remove all empty sections such as `Added`, `Removed`, etc.
* make sure all changes have references to GitHub issues in `#123` format (if possible)
* clean up all `Unreleased` sections and leave them empty
### Make release commit
Stage changed files for commit using `git add`. Commit the changes:
```shell
$ git commit -s -m 'Release '${NEOFS_TAG_PREFIX}${NEOFS_REVISION}
```
### Open pull request
Push release branch:
```shell
$ git push <remote> release/${NEOFS_TAG_PREFIX}${NEOFS_REVISION}
```
Open pull request to the main branch of the origin repository so that the
maintainers check the changes. Remove release branch after the merge.
## Tag the release
Pull the main branch with release commit created in previous step. Tag the commit
with PGP signature.
```shell
$ git checkout master && git pull
$ git tag -s ${NEOFS_TAG_PREFIX}${NEOFS_REVISION}
```
## Push the release tag
```shell
$ git push origin ${NEOFS_TAG_PREFIX}${NEOFS_REVISION}
```
## Post-release
### Prepare and push images to a Docker Hub (if not automated)
Create Docker images for all applications and push them into Docker Hub
(requires [organization](https://hub.docker.com/u/nspccdev) privileges)
```shell
$ git checkout ${NEOFS_TAG_PREFIX}${NEOFS_REVISION}
$ make images
$ docker push nspccdev/neofs-storage:${NEOFS_REVISION}
$ docker push nspccdev/neofs-storage-testnet:${NEOFS_REVISION}
$ docker push nspccdev/neofs-ir:${NEOFS_REVISION}
$ docker push nspccdev/neofs-cli:${NEOFS_REVISION}
$ docker push nspccdev/neofs-adm:${NEOFS_REVISION}
```
### Make a proper GitHub release (if not automated)
Edit an automatically-created release on GitHub, copy things from `CHANGELOG.md`.
Build and tar release binaries with `make prepare-release`, attach them to
the release. Publish the release.
### Update NeoFS Developer Environment
Prepare pull-request in [neofs-devenv](https://github.com/nspcc-dev/neofs-devenv)
with new versions.
### Close GitHub milestone
Look up GitHub [milestones](https://github.com/nspcc-dev/neofs-node/milestones) and close the release one if exists.
### Rebuild NeoFS LOCODE database
If new release contains LOCODE-related changes, rebuild NeoFS LOCODE database via NeoFS CLI
```shell
$ neofs-cli util locode generate ...
```
