# Changelog

All notable changes to this project, grouped by release tag. Development/pre-release
tags (`-dev.N`, `v1.devNNNN`) are excluded — only tagged releases are listed. Commit
noise (placeholder commits, CI/build-only tweaks, typo fixes) has been filtered out in
favor of a human-readable summary of user-facing changes per release.
