2.3.0

Happy 10th birthday, Chunky! 🥳
I'm afraid the cake did not make it into this version, so please take this one instead: 🍰

As always, a huge thank you to everyone who made this release possible! That does not just involve contributing code, but also reporting bugs, trying out new features, verifying if bugs are fixed, performance benchmarks, improving the documentation and submitting suggestions.

Special thanks go to @aTom3333, @073TheBoss, @jackjt8 and @NJDaeger. This changelog wouldn't be half as long without you. And, last but not least, to @llbit for creating Chunky and allowing us to maintain it. 🙏
