Highlights

This release focuses heavily on performance improvements of zio-streams and zio-test. In particular, users that rely heavily on TestClock in their test suites should experience a noticeable improvement in test execution and flakiness.

[!NOTE] This release breaks source compatibility of the ZStream#ensuringWith and ZSink#ensuringWith methods by changing the input argument from Exit[E, A] to Exit[Any, Any]. For more info on why this change was necessary please refer to https://github.com/zio/zio/issues/10216.

Most users should not be affected by this change, but if your code fails to compile after updating to zio v2.1.24 due to this change and there is no way to achieve the previous behaviour otherwise, please open an issue with your use-case and we'll look into it promptly.
