# How to Create a New Release
|
|
|
|
|
|
|
|
|
|
## Prerequisites
|
|
|
|
|
|
|
|
|
|
Install [releasetool](https://github.com/googleapis/releasetool).
|
|
|
|
|
|
|
|
|
|
## Create a release
|
|
|
|
|
|
|
|
|
|
1. `cd` into the root directory, e.g., `~/go/src/cloud.google.com/go`
|
|
|
|
|
1. Checkout the master branch and ensure a clean and up-to-date state.
|
|
|
|
|
```
|
|
|
|
|
git checkout master
|
|
|
|
|
git pull --tags origin master
|
|
|
|
|
```
|
|
|
|
|
1. Run releasetool to generate a changelog from the last version. Note,
|
|
|
|
|
releasetool will prompt if the new version is a major, minor, or patch
|
|
|
|
|
version.
|
|
|
|
|
```
|
|
|
|
|
releasetool start --language go
|
|
|
|
|
```
|
|
|
|
|
1. Format the output to match CHANGES.md.
|
|
|
|
|
1. Submit a CL with the changes in CHANGES.md. The commit message should look
|
|
|
|
|
like this (where `v0.31.0` is instead the correct version number):
|
|
|
|
|
```
|
|
|
|
|
all: Release v0.31.0
|
|
|
|
|
```
|
|
|
|
|
1. Wait for approval from all reviewers and then submit the CL.
|
|
|
|
|
1. Return to the master branch and pull the release commit.
|
|
|
|
|
```
|
|
|
|
|
git checkout master
|
|
|
|
|
git pull origin master
|
|
|
|
|
```
|
|
|
|
|
1. Tag the current commit with the new version (e.g., `v0.31.0`)
|
|
|
|
|
```
|
|
|
|
|
releasetool tag --language go
|
|
|
|
|
```
|
|
|
|
|
1. Publish the tag to GoogleSource (i.e., origin):
|
|
|
|
|
```
|
|
|
|
|
git push origin $NEW_VERSION
|
|
|
|
|
```
|
|
|
|
|
1. Visit the [releases page][releases] on GitHub and click the "Draft a new
|
|
|
|
|
release" button. For tag version, enter the tag published in the previous
|
|
|
|
|
step. For the release title, use the version (e.g., `v0.31.0`). For the
|
|
|
|
|
description, copy the changes added to CHANGES.md.
