This bugfix release closes a number of issues:

• #374 Added const generics support to rkyv_typename and fixed a name collision with generated code and errors when using lifetimes as generics
• #378 Fixed a regression that caused BufferScratch to be !Sync
• #379 Upgraded rkyv's supported version of uuid and fixed some feature unification problems
• #381 Fixed a missing ?Sized bound on some wrapper type impls
• #387 Relaxed an unnecessary Sized bound for the inherent TypeName impl

It also resolves an issue when validating tuples by upgrading rkyv's bytecheck version to 0.6.11.

Thanks to @c410-f3r, @mkatychev, @ChillFish8, and @edfraenkel for their hard work!

This bugfix release includes a number of additions and fixes:

• #342 and #364 Add missing PartialOrd<&str> and PartialOrd<String> impls for ArchivedString
• #346 Adds a From<T> impl for ArchivedOption<T>
• #350, #351, #352, #355, #359, #360, and #372 Improve the performance and expand the capabilities of AlignedVec
• #358 and #361 Disambiguate associated types generated in derive macros
• #357 Corrects disabled Send impls on BufferScratch
• #344 Bumps rkyv's bytecheck dependency to 0.6.10, re-exports the crate, and provides a more convenient #[archive(check_bytes)] attribute to derive CheckBytes with rkyv's supported bytecheck version. See the new examples for more details.

Additionally, rkyv's test suites once again pass MIRI under the new tree borrows model. You can test your own code that uses rkyv for undefined behavior by enabling tree borrows on your own projects.

Thanks to @mkatychev, @Qqwy, @brahms116, @myronahn, @overlookmotel, @samlich, @freqmod, and @MaxOhn for their contributions to this release!

Thanks to everyone who contributed issues and PRs!

This bugfix release properly gates Arc support behind the has_atomics flag to fix rkyv on thumbv6m-none-eabi and other platforms without atomics support running under no_std.

Thanks to @moosingin3space for the bug report.

This bugfix release introduces the Unsafe wrapper type for serializing and deserializing Cell and UnsafeCell.

This bugfix release corrects documentation on AlignedVec::into_boxed_slice that was not correctly updated with the previous release.

Thanks to @ralfjung for spotting the issue.

This bugfix release corrects some minor potential UB in AlignedVec::into_boxed_slice. It is a second location of a similar issue patched in 0.7.29.

Thanks to @saethlin for identifying and reporting the issue securely.
