Conventional Commits

This project uses Conventional Commits to automate versioning and changelog generation. Use the following prefixes in your commit messages:

Prefix	Version bump	Example
fix: …	patch (1.0.x)	fix: correct cell resolution output
feat: …	minor (1.x.0)	feat: add ISEA4T grid support
feat!: … / fix!: …	major (x.0.0)	feat!: rename cellToChildren

A release PR is opened automatically by the bot after commits land on main. Merging it creates the GitHub release and publishes to npm.
