v0.4.0

This release changes some major APIs and adds shared pointer support:

#32 Introduces new context traits in place of the previous context struct.
#33 Allows serialization parameterization over the type of the serializer, allowing users to choose the complexity of their serializers and create their own.
#34 Renames Unarchive to Deserialize.
#35 Splits Archive into Serialize to allow a clean hierarchy while still enabling parameterization.
#39 Removes the Resolve trait and simplifies the API.
#37 Performed some cleanup on the rkyv_dyn API.
#36 Added shared and weak pointer support.
#41 Added validation support for shared and weak pointers.
#40 Added deserialization contexts to match serialization and verification contexts.
#47 Introduced Serializers and Deserializers.
#42 Added an attribute to rename the resolver type for archived values.
#51 Fixed a performance regression.
#45 Updated and greatly improved the book's documentation.
#59 Introduced the ptr_meta crate and vastly reduced the number of dangerous transmutations.
#56 Added archive implementations for usize and isize.
#55 Made the support for 32/64-bit much more uniform and consistent.

Thanks to everyone who contributed by asking questions, filing issues, and making feature requests.

v0.3.1

This bugfix corrects atomic implementations for embedded systems and untangles some dev dependencies that made it difficult to publish crates.

Bugs fixed:

• #58 Atomic support is now enabled and disabled properly for embedded systems.

v0.3.0

v0.3.0 changes a few major APIs, adds new features, simplifies the framework, and adds lots of documentation:

• #9 #19 Replace the current archived HashMap implementation with a minimal perfect hashmap implementation. This greatly reduces memory use, but also fixes compatibility issues with the previous implementation. Archive time for hashmaps will likely increase as a result.
• #22 Adds the Unarchive trait with counterparts for unsized types and trait objects. Unarchive is a direct replacement for deserialization and converts archived types back into their unarchived forms.
• #24 Removes WriteExt and SeekExt and folds their functionality into Write and Seek respectively.
• #23 Improves validation performance by a modest amount in most cases.
• #27 Makes it an error to use both #[archive(copy)] and #[archive(name = "...")] or #[archive(derive(...))].
• #25, #30 Adds a book with more narrative documentation on rkyv architecture and features.
• #28 Adds more extensive tests and benchmarks.
• #29 Renames ArchiveSelf to ArchiveCopy and SelfResolver to CopyResolver. The derive argument is now #[archive(copy)].

v0.2.1

v0.2.1 adds some small new features and fixes a handful of bugs:

• #14 Empty slices no longer align the writer, which avoids wasting space in some cases.
• #17 With the strict feature, all archived types will be #[repr(C)]. This is probably unnecessary except for the extra cautious.
• #18 A loophole in trait object validation has been patched which could have allowed malicious code execution.
• #21 The Seek trait has been added, along with the archive_root helper. This allows archiving the root object at position 0 in the archive, which is useful for self-describing formats like files and messages.
• #20 Ranges, atomics, and nonzero integer types are now supported by rkyv.

v0.2.0

This is a major feature release, adding a wide variety of new features and plugging some existing holes:

#7 Relative pointers now have 64-bit support through the long_rel_ptrs feature.
#8 Mutable archives can now be created and mutated through pinned references.
#11, #16 bytecheck support has been added, allowing for archive validation. Bytecheck is built with the explicit goal of validating untrusted and potentially malicious data.
#12 The core and std archived types are now exposed and documented.
#13 Duplicate impls now provide a much more friendly error message to help you track down the problem.
#15 Recursive data structures can now be archived properly with use of the #[recursive] attribute on recursive fields.

The next release will be v0.2.1 with any bugfixes and non-breaking changes.

v0.1.1

This is a bugfix release to address issues discovered after the previous release and minor feature shortcomings:

#2 Crates with no_std support need #![no_std]
#3 Examples allow buffer mutation after archiving
#4 Archived fields don't match the visibility of their unarchived counterparts
#5 Doesn't compile on rustc < 1.47

Actions have also been set up for the repo to automatically build and run tests.
