[dependabot]

Updates the requirements on dnspython to permit the latest version.

Release notes

Sourced from dnspython's releases.

dnspython 2.4.2

This is a bug fix release, see the What's New page in the documentation for a summary.

Thanks to the people who reported the bugs and, as usual, thanks to my co-maintainers: Tomáš Křížek, Petr Špaček, and Brian Wellington.

Changelog

Sourced from dnspython's changelog.

2.4.2

• Async queries could wait forever instead of respecting the timeout if the timeout was 0 and a packet was lost. The timeout is now respected.

• Restore HTTP/2 support which was accidentally broken during the https refactoring done as part of 2.4.0.

• When an inception time and lifetime are specified, the signer now sets the expiration to the inception time plus lifetime, instead of the current time plus the lifetime.

2.4.1

• Importing dns.dnssecalgs without the cryptography module installed no longer causes an ImportError.

• A number of timeout bugs with the asyncio backend have been fixed.

• DNS-over-QUIC for the asyncio backend now works for IPv6.

• Dnspython now enforces that the candidate DNSKEYs for DNSSEC signatures have protocol 3 and have the ZONE flag set. This is a standards compliance issue more than a security issue as the legitimate authority would have to have published the non-compliant keys as well as updated their DS record in order for the records to validate (the DS digest includes both flags and protocol). Dnspython will not make invalid keys by default, but does allow them to be created and used for testing purposes.

• Dependency specifications for optional features in the package metadata have been improved.

2.4.0

• Python 3.8 or newer is required.

• The stub resolver now uses instances of dns.nameserver.Nameserver to represent remote recursive resolvers, and can communicate using DNS over UDP/TCP, HTTPS, TLS, and QUIC. In additional to being able to specify an IPv4, IPv6, or HTTPS URL as a nameserver, instances of dns.nameserver.Nameserver are now permitted.

• The DNS-over-HTTPS bootstrap address no longer causes URL rewriting.

• DNS-over-HTTPS now only uses httpx; support for requests has been dropped. A source port may now be supplied when using httpx.

• DNSSEC zone signing with NSEC records is now supported. Thank you

Looks like dnspython is up-to-date now, so this is no longer needed.
