Thank you for all the work you put into this sequence of PRs — I appreciate the effort!

A v0.12.1 tag sounds reasonable for the current changes since v0.12.0.

I think the existing usage of [Unreleased] and [unreleased] is fine because it's consistent with the Keep a Changelog format.

I've tried to revisit your other PRs but I don't have the capacity to review them properly due to the combined scope and volume.

I did however notice a few changes I'm hesitant about, especially without prior discussion:

• Added logging
• File moves
• Function renames
• Line endings?
• Copyright notice changes

I feel bad about rejecting PRs but I'm leaning in that direction.

On a similar note, I've tried to redesign the API and internals a number of times myself, but I was never happy with my efforts. I do however believe that there's a need for a foundational cleanup.

@Leopotam also makes a fair point; forking might be the more practical route for those who want these PRs merged. The original author/maintainers appear to have moved on, and my spare time has also been very limited for a while.
