This is a patch release, now the main release for v6 as v6.0.0 was yanked shortly after release.

Thanks to @JesusGuzmanJr for notifying me about a critical bug that was introduced so that I could resolve it: #304.

PRs for this release: #305 + https://github.com/xacrimon/dashmap/commit/d5c8be6213ca85d7e3ccbcc1eb5b95651ce7e253

This release contains performance optimizations, most notably 10-40% gains on Apple Silicon but also 5-10% gains when measured in Intel Sapphire Rapids. This work was accomplished in:

Okay, I'll promise to slow down the micro-releases a little but I'd rather keep you folks updated than not. This version bumps the MSRV to 1.65 which is quite old now due to dependency requirements. This was not a choice we could make ourselves without pinning dependencies and causing code duplication for many of dashmap's users.

This release merely reverts #259 since it introduced data race violations. We'll look into this more in the coming time and try to investigate why and how to gain back the additional 0.5%-ish lost performance. Additionally, v5.5.1 has been yanked.

Thanks to @Turbo87 and the crates.io team for reporting this issue.
