This release has an MSRV of 1.88.

In the nearly six months since the last release, we have put a lot of focus into making Xilem and Masonry more suitable for general use. In addition, we have gained several important features, including initial support for using Masonry with multiple windows. As Xilem and Masonry are beginning to move towards improved stability, we plan to start keeping a changelog after this release. Note that this is alpha-quality software. There are plenty of missing features. We expect to continue active development, including making major breaking changes.
