Issue metrics

We keep track of how many issues are closed at the end of the month in docs/issue-metrics. We use this to keep track of our issues and see our progress! 📈

Versioning

Zen uses Semantic Versioning, meaning versions are displayed as a.b.cd where:

• a is the major version
• b is the minor version
• c is the branch prefix
• d is the patch version

Branches

Zen is divided into 2 main branches. We use dev for development and stable for stable releases. The dev branch is where all the new features are added and where twilight builds are generated. The stable branch is where the stable releases are generated.

We divide into 2 branches in case there's any really important security update (for example) that needs to be released before the next stable release. This allows us to do patches without releasing unstable versions to the public.

⚡ Performance

Zen is built with performance in mind, and we have optimized the browser to be as fast as possible! Checkout the latest performance benchmarks!
