Release process

Sync with Google code

• Sync with Google main branch and make PR
• Fix all merge conflicts

Linux Dockers

We disabled OpenSUSE Dockerfile for now, since it is still broken on Google's side.

Submodules

The Shaka uses cURL as submodule. Please make sure you are pointed to the correct branch (the same as original shaka branch). Don't update it, otherwise it will break the build.

If you do not see code in packager/third_party/*/source, then you should run make submodules to download all of the submodules in this project, otherwise you will not be able to build Shaka locally as native code or within docker.
