0.10.0

Breaking changes

• All types and functions referring to domain names have been changed from using the term “dname” to just “name.” For instance, Dname has become Name, ToDname has become ToName, and ToDname::to_dname has become ToName::to_name. (#290)
• The ToName and ToRelativeName traits have been changed to have a pair of methods a la try_to_name and to_name for octets builders with limited and unlimited buffers, reflecting the pattern used elsewhere. (#285)
• The types for IANA-registered parameters in base::iana have been changed from enums to a newtypes around their underlying integer type and associated constants for the registered values. (This was really always the better way to structure this.) (#276, #298)
• The Txt record data type now rejects empty record data as invalid. As a consequence TxtBuilder converts an empty builder into TXT record data consisting of one empty character string which requires TxtBuilder::finish to be able to return an error. (#267)
• Txt record data serialization has been redesigned. It now serialized as a sequence of character strings. It also deserializes from such a sequence. If supported by the format, it alternatively deserializes from a string that is broken up into 255 octet chunks if necessary. (#268)
• The text formatting for CharStr has been redesigned. The Display impl now uses a modified version of the representation format that doesn’t escape white space but also doesn’t enclose the string in quotes. Methods for explicitly formatting in quoted and unquoted presentation format are provided. (#270)
• The validate::RrsigExt trait now accepts anything that impls AsRef<Record<..>> to allow the use of smart pointers. (#288 by @hunts)
• The stub resolver now uses the new client transports. This doesn’t change how it is used but does change how it queries the configured servers. (#215)
• The sub resolver’s server configuration Transport type has been changed to be either Transport::UdpTcp for trying UDP and if that leads to a truncated answer try TCP and Transport::Tcp for only trying TCP. The stub resolver uses these accordingly now (#296)
• Many error types have been changed from enums to structs that hide internal error details. Enums have been kept for errors where distinguishing variants might be meaningful for dealing with the error. (#277)
• Renamed Dnskey::is_zsk to is_zone_key. (#292)
• Split RRSIG timestamp handling from Serial into a new type rdata::dnssec::Timestamp. ([#294])
• Upgraded octseq to 0.5. (#257)
• The minimum Rust version is now 1.70. (#304)

New

• Add impls for AsRef<RelativeDname<[u8]>> and Borrow<RelativeDname<[u8]>> to RelativeDname<_>. (#251 by @torin-carey)
• Added name::Chain::fmt_with_dots to format an absolute chained name with a final dot. (#253)
• Added a new ParseAnyRecordData trait for record data types that can parse any type of record data. (#256)
• Added implementations of OctetsFrom and Debug to AllOptData and the specific options types that didn’t have them yet. (#257)
• Added missing ordering impls to ZoneRecordData, AllRecordData, Opt, and SvcbRdata. (#293)
• Added Name::reverse_from_addr that creates a domain name for the reverse lookup of an IP address. (#289)
• Added OptBuilder::clone_from to replace the OPT record with the content of another OPT record. (#299)
• Added Message::for_slice_ref that returns a Message<&[u8]>. (#300)

Bug fixes

• Fixed the display implementation of name::Chain<_, _>. (#253)
• Fixed the display implementation of rdata::Txt<..>. It now displays each embedded character string separately in quoted form. (#259)
• Fixed the extended part returned by OptRcode::to_parts (it was shifted by 4 bits too many) and return all 12 bits for the Int variant in OptRcode::to_int. (#258)
• Fixed a bug in the inplace zonefile parser that made it reject character string of length 255. (#284)

Unstable features

• Added the module net::client with experimental support for client message transport, i.e., sending of requests and receiving responses as well as caching of responses.
  This is gated by the unstable-client-transport feature. (#215,#275)
• Added the module net::server with experimental support for server transports, processing requests through a middleware chain and a service trait.
  This is gated by the unstable-server-transport feature. (#274)
• Added the module zonetree providing basic traits representing a collection of zones and their data. The zonetree::in_memory module provides an in-memory implementation. The zonetree::parsed module provides a way to classify RRsets before inserting them into a tree.
  This is gated by the unstable-zonetree feature. (#286)
