Hello!

Today we released the second, and hopefully last, Release Candidate for Authoritative \
Server version 4.5.0. Please try it!

Version 4.5.0 mostly brings small improvements and fixes, but there are two notable \
new features:

* The ‘zone cache', which allows PowerDNS to keep a list of zones in memory, \
updated periodically. With this cache, PowerDNS can avoid hitting the database with \
queries for unknown domains. In some setups, and some attack scenarios, this can make \
a serious performance difference. Many thanks to Chris Hofstaedtler for implementing \
this.

* Priority ordering in the AXFR queue in PowerDNS running as a secondary. Some users \
with a lot of domains (>100k) sometimes found real changes waiting behind signature \
refreshes on Thursdays. With the new ordering, those real changes can ‘skip the \
line' and get deployed on your secondaries faster. Many thanks to Robin Geuze for \
implementing this.

Since 4.5.0-beta1, the zone cache is enabled by default.

A full list of changes can be found in the [1]changelog.

Please make sure to read the [2]Upgrade Notes before upgrading.

With version 4.5.0, support for platforms with a time_t type smaller
than 64 bits is dropped. This means that we do not build packages for
Raspberry Pi OS.

The [3]tarball ([4]signature) is available at
[5]downloads.powerdns.com. Packages for various distributions are
available from [6]repo.powerdns.com.

Please send us all feedback and issues you might have via the
[7]mailing list, or in case of a bug, via [8]GitHub.
