## 0.5.0
This release contains a major restructuring and refactoring of the entire
library. The previous set of crates has been merged into a single crate
yet again with various modules being optional and available via features.
### Changes to former *domain-core*
The following notes list the changes relative to the *domain-core* crate.
Reorganization
* The modules in `domain_core::bits` have been moved to `domain::base`.
* The modules `domain_core::{iana, utils}` have been moved to
`domain::base::{iana, utils}` respectively.
* Master file parsing and generation functionality is now only available
if the feature `"master"` is enabled.
Breaking Changes
* All types that use octets sequences are now generic over the specific
type of sequence. For details of the mechanism, please have a look at
the documentation of the `base::octets` module.
* `rdata::rfc4035::Nsec` is now generic over the type of the next name.
This is necessary because [RFC 6762] allows compression for its next name.
([#20], reported by Tom Pusateri)
* Removed the failure crate. All error types now impl `fmt::Display` and,
if the `"std"` feature is enabled, `std::error::Error`. [(#33)]
New
* `base::message::Message::opt` returns a message’s OPT record if present.
([#6], thanks to Marek Vavruša!)
* unsafe `base::name::Dname::from_bytes_unchecked` in order to create
names from well-known sequences. [(#31)]
* `compose::Compose::compose_canonical` for composing the canonical form
for DNSSEC signing. It has a default implementation just doing `compose`
and has been implemented for all relevant types. [(#XX)]
* `base::cmp::CanonicalOrd` for the ordering of record data and records for
DNSSEC signing. Implemented for all relevant types. Also improved
implementations of `PartialEq` and `PartialOrd` for types generic over
domain name types to be generic over the other values domain name type.
* Allow `serial::Serial` to be created from datetimes, provide a
constructor for `now` and add `sub`.
* Record data types for CDS and CDSKEY record types. (Provided by [@vendemiat]
in [#24]).
Bug fixes
* Do not compress the target of an SRV record’s data. [(#18)]
* Fix multiple issues with `rdata::rfc4043`. ([#42] via [#38] by [@vavrusa])
* Fix multiple issues with `base::opt`. ([#42] via [#38] by [@vavrusa])
* Fixed infinite loops in `Message::canonical_name`. ([#42] via [#38] by
[@vavrusa])
Dependencies
* The `std`, `bytes`, and `chrono` crates are now optional and can be enabled
via features.
### New
* The new `sign` module provides DNSSEC signing. It is available if the
`"sign"` feature is enabled.
* The new `tsig` module provides TSIG signing and validation. It is only
available if the `"tsig"` feature is enabled.
* The new `validate` module provides functionality necessary for DNSSEC
validation. It is only available if the `"validate"` feature is enabled.
