v5.5.2

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.

v5.5.3

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.

v5.5.1

This release includes a couple of internal changes such as committing Cargo.lock as well as minor optimizations to lookup performance.

v5.5.0

Hey folks. This time is not especially different. This release contains QoL improvements, some bugfixes to get around panics and then panic message improvement as well as the usual ephemeral dep updates.

v5.4.0

Hey folks, another small maintenance release with some QoL improvements

Changes

• #223
• #222
• #221
• #209

v5.3.4

This release switches to a non-spinlock lock implementation.
This improves worst-case performance and gets rid of a possible but in-practice non-catastrophic data-race.

v5.3.3

This release reverts #194 since it introduced bugs that require a breaking API change to fix.

v5.3.2

Hi!

This release includes a minor feature set tweak, removing the transient dependency on ahash from hashbrown: #205

v5.3.1

Hi folks!

This short patch release improves the performance of the new custom locks I had to hastily adapt to fix the deadlock bug mentioned in the v5.3.0 release notes. Further improvements will be made as time goes on, contributions and ideas accepted.

v5.3.0

DashMap v5.3.0 is a maintenance release featuring various bug fixes and some new features!

Changelog:

• Only invoke the hasher once per write operation: #194
• Set the default hasher type for VacantEntry and OccupiedEntry: #193
• Use std:🧵:available_parallelism in place of num_cpus: #199
• Introduce mapped references: #203
• Fix #191, #201, #195: #202

Thanks to @joshtriplett, @stepancheg, @artemshein, @skyzh, @RustyYato, @donkeyteethUX and others involved for making this release possible.
