When enough changes have accumulated, it is time to release new version of Catch. This document describes the process in doing so, that no steps are forgotten. Note that all referenced scripts can be found in the `tools/scripts/` directory.
These steps are necessary and have to be performed before each new release. They serve to make sure that the new release is correct and linked-to from the standard places.
Catch uses a variant of [semantic versioning](http://semver.org/), with breaking API changes (and thus major version increments) being very rare. Thus, the release will usually increment the patch version, when it only contains couple of bugfixes, or minor version, when it contains new functionality, or larger changes in implementation of current functionality.
After deciding which part of version number should be incremented, you can use one of the `*Release.py` scripts to perform the required changes to Catch.
Once a release is ready, release notes need to be written. They should summarize changes done since last release. For rough idea of expected notes see previous releases. Once written, release notes should be added to `docs/release-notes.md`.
After version number is incremented, single-include header is regenerated and release notes are updated, changes should be committed and pushed to GitHub.
