v2.2.1
This is another significant update, bringing 2D support, lossless roundtrip of Manifolds through glTF, Python bindings published on PyPI, and a whole new triangulator that fixes lots of geometric edge cases in the Boolean. And of course many bug fixes and performance improvements - a huge thank you to all the contributors!

- Fixed a variety of geometrically incorrect complex Boolean results. This all comes down to our polygon triangulator, which had grown increasingly complex. I finally decided to pull the plug and start over with a new algorithm. It is now simpler and significantly more robust. The test suite was also expanded considerably. Developing this new algorithm was the main driver pushing this release to be a few months later than intended. #564 (@elalish)

v2.1.0
This is a significant update, primarily centered on replacing MeshRelation with MeshGL, which accomplishes the goal of maintaining material properties across operations much better and with a simpler, more performant API. I'm not considering this a breaking change, as MeshRelation turned out to be broken enough that I doubt it was getting much use anyway. For the WASM build on npm, this is definitely a breaking change as we've updated its API more significantly and switched to an ES6 module. This brings us up from v1.0 to v2.1 to keep a consistent version from now on.
New Features

MeshGL. #269 (@stewartoallen, @elalish) - Handle arbitrary properties in

v1.0.0
I'm marking this first release as v1.0 because I've been working on it long enough and it passes a rigorous enough batch of tests that I'm convinced it really is a next step in robust computational geometry. Obviously I can't promise it's bug-free, but I believe at this point the fundamental architecture is sound and can be built upon. Likewise, after many false starts I believe I have an API that is durable and can be expanded without major breaking changes.
In short, I feel comfortable recommending you try using it and building on it, and that I won't be wasting your time.
