New

* `ca::idexchange::Error` now impls `std::error::Error`. ([#297])
* Re-export `bcder` as `dep::bcder` if it is enabled. ([#299])
* Added `PublisherRequest::set_publisher_handle`. ([#300])
* Added `uri::{Rsync,Https}::path_into_dir` ([#302])
* Added `Ipv4Block` and `Ipv6Block` and `FromIterator` impls for
  `Ipv4Blocks` and `Ipv6Blocks`. ([#298])
* Made `AddressRange` public and added methods to convert ranges into
  a set of prefixes. ([#306])
* Updated the ASPA RTR PDU to conform with version -14 of
  draft-ietf-sidrops-8210bis. ([#309])
* Enable ASPA version 2 in the RTR server. ([#318])
* The ASPA `ProviderAsSet` now keeps track of its length and exposes it
  via the new `len` method. ([#315])
* The ASPA Provider AS Set is now limited to 16380 entries when parsing from
  ASPA objects and creating RTR PDUs. ([#316])
* Exposed `ca::idcert::TbsIdCert::validity`. ([#310]);
* Protect against maliciously large XML input to the RRDP parser. This
  will allow re-enabling GZIP support in RRDP clients. ([#319])

Bug fixes

* Do not allow backslashes in idexchange handles. ([#304])
* Check the content of file names in a manifest during parsing. This fixes a
  crash when later code assumes that the file names only contain ASCII
  characters and otherwise panics. ([#320])

Other changes

* The minimum supported Rust version is now 1.73. ([#319])
