Changelogs for 4.5.x
====================
+.. changelog::
+ :version: 4.5.0-rc2
+ :released: 6th of July 2021
+
+ This is the second, and hopefully last, release candidate for version 4.5.0 of the Authoritative Server.
+ This release contains a ton of improvements and bug fixes compared to 4.4, but very few user visible changes.
+
+ 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.
+
+ Please make sure to read the :doc:`upgrade notes <../upgrading>` before upgrading.
