# Changelog
This project does NOT follow semantic versioning. The version increases as
follows:
1. Major version updates are breaking updates to the build infrastructure.
These should be very rare.
2. Minor version updates are made for every major Buildroot release. This
may also include Erlang/OTP and Linux kernel updates. These are made four
times a year shortly after the Buildroot releases.
3. Patch version updates are made for Buildroot minor releases, Erlang/OTP
releases, and Linux kernel updates. They're also made to fix bugs and add
features to the build infrastructure.
