- Update CHANGELOG.md - Update to bundled capnproto-1.0.1 * Compiles with capnproto-0.8.0 and higher - *Breaking Change* Remove allow_cancellation (see https://capnproto.org/news/2023-07-28-capnproto-1.0.html) * This is tricky to handle for older versions of capnproto. Instead of dealing with lots of complication, removing it entirely. - Fix some documentation after the build backend support was added - Update tox.ini to support 3.8 to 3.12 - Update cibuildwheel to 2.16.1 * Adds Python 3.12 supports and implicitly deprecates EOL 3.7 (though it's still built)
