# Release We will perform a release every six weeks. Theoretically, this is to make a release every time Chromium makes a stable release (which is every six weeks). For now, we plan to do only major releases and no minor releases(Unless really needed). We have a milestone attributed to every release, this can be used to follow the fixes/features in our [issue tracker](https://github.com/01org/ozone-wayland/issues?milestone=1&state=open).

At this given point, we plan to only have beta and stable channel. You can read more information about release channels here

## Source Release

We do a pre-release tag on the above-mentioned dates. The pre-release will be done with tip of the master on that given day. Next, few days will be more of a testing period and ensuring a stable release. At this point, stable means an at-least to be able to launch the browser and no new regressions. Once ready, we tag the release. The release tag may happen with same commit as pre-release tag or another depending on any issues found during testing phase. One should be able to download the source code tar ball from [release section] (https://github.com/01org/ozone-wayland/releases).

Every release has notes containing the following information:

  1. Release and milestone information.
  2. Supported Mesa and Wayland version.
  3. Bugs fixed in release.
  4. New features supported.
  5. Contributor names.

Before upgrading any existing release, please [read] (http://www.chromium.org/getting-involved/dev-channel#TOC-What-should-I-do-before-I-change-my-channel-) this.

## Ozone-Wayland developers- Tagging a Release

A good starting point is to read GitHub documentation related to making releases

One need to follow these steps for tagging a new release:

A good starting point is to read GitHub documentation related to making releases

One need to follow these steps for tagging a new release:

  1. Create a release branch from tip of master branch and do a pre-release tag. One can do this directly in GitHub release section. For tag version provide the output of the command ./chrome --version. For release title provide 'Chromium Wayland Browser + tag version'. Check This is a pre-release option.
  2. Test for any regressions.
  3. If any additional changes needed from the Ozone - Wayland side, push the changes to release and master branch. Any changes needed from chromium side, add them into patches and push them to release branch only.
  4. Tag release. If nothing has changed from pre-release tag version, edit the pre-release tag and uncheck pre-release option. If we had pushed more changes into the release branch, tag tip of release branch(similar to 1 but don't select pre-release option).
  5. Delete any pre-release tags.
  6. Generate binaries from source package and upload them to 01.org. There's a simple hack for preparing the binary, where it shows how to create a tarball from the build directory that excludes a few files.
## Working with Ozone-Wayland Release branch These instructions assume Ozone-Wayland environment has already been setup.

Edit your .gclient and set: "managed": False,

Note: When working with Ozone-Wayland Master, we need managed to be True but with Release branch it needs to be False.

cd ~git/chromium # (Your top level directory).
gclient sync --with_branch_heads
cd src/

BRANCH=1809 # Branch number of the release. One can find this information as part of release notes.
git config --replace-all svn-remote.svn_$BRANCH.url http://src.chromium.org/chrome
git config --replace-all svn-remote.svn_$BRANCH.rewriteRoot "svn://svn.chromium.org/chrome"
git config --replace-all svn-remote.svn_$BRANCH.rewriteUUID "0039d316-1c4b-4281-b951-d872f2087c98"
git config --replace-all svn-remote.svn_$BRANCH.fetch branches/$BRANCH/src:refs/remotes/origin/$BRANCH
echo "ref: refs/remotes/branch-heads/$BRANCH" > .git/refs/remotes/origin/$BRANCH
git svn fetch svn_$BRANCH

git checkout -b branch_$BRANCH origin/$BRANCH # Checkout Release branch.
git config branch.branch_$BRANCH.merge refs/heads/$BRANCH # Make git-cl happy.
git config branch.branch_$BRANCH.remote branch-heads

cd .. # (cd to top level directory)

gclient sync # Checkout all submodules at their branch DEPS revisions.
./src/ozone/patches/patch-chromium.sh # Apply Ozone-Wayland specific patches.
