This bugfix release addresses the following issues:

• #548 Makes the AsVec wrapper compatible with any choice of hasher
• #549 Access pointer validation fails for nested HashMaps

This bugfix release corrects an infinite loop in hash map probing.

It's finally here! A ton of stuff has changed, so here are some highlights:

• API free functions are now more ergonomic and consistently-named. See to_bytes, from_bytes, access, and everything else!
• rkyv now provides separate "API levels" for high-level Rust code and low-level Rust code.
• Error handling has been completely overhauled with the introduction of rancor. Validation, serialization, and deserialization all now accept error type parameters so you can choose how you want errors to accumulate.
• rkyv now supports remote derive! Read all about it in the book.
• Unaligned primitives are now supported via the unaligned feature. If you choose, no more worrying about buffer alignment!
• Native endianness is no more. rkyv now defaults to little-endian, aligned, and 32-bit relative pointers. Use the format control features to change them if you want.
• A few semver-affecting soundness issues have been fixed. rkyv should now really truly and always generate cross-platform buffers.
• The archived hash map and b-tree map implementations have been overhauled for better space-efficiency and performance.
• Macro attributes have been overhauled to make them significantly more cohesive and ergonomic.
• rkyv's mutable API has been overhauled for improved soundness and ease of use.
• rkyv's internal APIs have been overhauled for improved ease of use.
• Many serialization and deserialization types and traits have been renamed for shortness and clarity.
• Copy optimizations are now stable for many basic primitive types.
• The Most Unhelpful Error no longer occurs (the compiler mentions With<_, _> when you try to deserialize)
• AlignedVec now supports custom alignments
• No more strict feature, rkyv is always in strict mode now
• Lots and lots and lots of tech debt cleanup

... and much more! Try it out yourself after I release this new version on-stage at RustConf.

Reminder: this is a major version bump, and data previously serialized with rkyv 0.7 or below will not be compatible with 0.8. Any data you serialize in 0.8 is guaranteed to be compatible for the lifetime of the 0.8 releases.

This is the first release candidate for rkyv 0.8.0.

This bugfix release closes a number of issues:

• Fix documentation typo (#433)
• Add a with_capacity constructor for SharedSerializeMap, SharedDeserializeMap, DefaultValidator, and SharedValidator (#432)
• Fix tinyvec/alloc feature cfg and docs (#428)
• Use the Entry API to avoid double hash lookups (#426)
• Preallocate HashMap/HashSet data on deserialize (#427)
• Fix documentation typo (#422)
• Add support for VecDeque (#414)
• Add smol_str support (#411)
• Add some ergonomic APIs to Option and Result (#413)
• Add tokio Bytes suport (#408)

Thanks to everyone who helped contribute to this release: @gz, @monoid, @b8591340, @alvra, @blp, @al8n, @cholcombe973, and @FallingSnow.

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!

This bugfix release extends Send and Sync impls to a few more types.

Thanks to @nagisa for filing an issue!

This bugfix release addresses the following issues:

• #241 Support for niching nonzero integers has been added. Using #[with(Niche)] on Option<NonZero*> fields will only use as much space as the underlying integer type while archived.
• #240 SystemTime can now be serialized and deserialized using #[with(UnixTimestamp)], which converts the time to a duration since the UNIX epoch.
• #242 SharedSerializeMapError has been made Send and Sync.
• #243 Malformed arguments to #[archive(...)] and #[archive_attr(...)] will now properly error. Previously, malformed arguments caused the attribute to be silently ignored.

Thanks to @nagisa, @seritools, @kassens, and @ok-nick for reporting issues and filing feature requests.

This bugfix release addresses the following issues:

Thanks to @remilauzier for filing an issue!

0.7.27 is a bugfix release that fixes some issues and adds a few new features:

• #234 Adds direct support for the hashbrown crate. This allows users to archive hash maps and hash sets without also needing std.
• New helper functions have been added to make serialization and deserialization easier than ever: to_bytes, from_bytes_unchecked, and from_bytes. These are utility functions to make working with serialization and deserialization easier, but may not provide the best possible performance for individual cases.
• A usage-tracking scratch space adapter has been added for performance tuning.
• A debug assertion message regarding buffer alignment has been fixed to provide the correct error message.
• The HeapScratch struct can now be used with const parameter N=0.
• Examples have been updated.

Thanks to @Miaxos for feature requests and a PR!

This bugfix release improves atomics support detection to provide atomics support to more targets.

Thanks to @tobz for the PR.

This bugfix release fixes #227 by removing the custom pad impl for BufferSerializer. This will cause the serializer to always write zeroes to padding to avoid surprises when reusing buffer memory. Thanks to @Diomendius for reporting an issue.

0.7.23 is a bugfix release that fixes some unused code warnings on platforms without atomic support.

This bugfix release improves the documentation for generated types. Thanks to @dvc94ch for the suggestion!

#[derive(Archive, Serialize)]
pub struct Example<'a> {
    #[with(CopyOptimize, RefAsBox)]
    slice: &'a [u32],
}

and serialize a field as a box with copy optimization. Thanks to @tobz for the feature request.

rkyv 0.7.18 addresses a deficiency in the bounds(...) argument to the archive attribute. Bounds can now be provided for the Archive, Serialize, and Deserialize traits individually.

rkyv 0.7.17 adds the new Niche wrapper, which allows fields of the form Option<Box<T>> to use less space.

rkyv 0.7.16 extends support to rend types and adds a compile error when multiple mutually exclusive features are active.

This release also contains rkyv_dyn 0.7.6, which fixes a few things that broke during rkyv's evolution.

Thanks to @b8591340 especially for filing issues and PRs.
