Hello! We are proud to announce the release of PowerDNS Recursor 4.8.0.
Compared to the previous major (4.7) release of PowerDNS Recursor, this
release contains the following major changes:
* [1]Structured Logging has been implemented for almost all
subsystems. This allows for improved (automated) analysis of
logging information. We've posted a [2]blog about this feature
recently.
* Optional [3]Serve Stale functionality has been implemented,
providing resilience against connectivity problems towards
authoritative servers.
* Optional [4]Record Locking has been implemented, providing an extra
layer of protection against spoofing attempts at the price of
reduced cache efficiency.
* Internal tables used to track information about authoritative
servers are now [5]shared instead of per-thread, resulting in
better performance and lower memory usage.
* EDNS padding of outgoing DoT queries has been implemented,
providing better privacy protection.
* Metrics have been added about the protobuf and dnstap logging
[6]subsystems and the [7]rcodes received from authoritative
servers.
As always, there are also many smaller bug fixes and improvements,
please refer to the [8]changelog for additional details. When upgrading
do not forget to check the [9]upgrade guide.
We are also announcing the removal of [10]XPF support. If you are using
this feature, switch to the [11]Proxy Protocol.
Please send us all feedback and issues you might have via
the [12]mailing list, or in case of a bug, via [13]GitHub.
The [14]tarball ([15]signature) is available from our download
[16]server and packages for several distributions are available from
our [17]repository.
With the 4.8.0 release, the 4.5.x releases will be marked "End of Life"
and the 4.6.x and 4.7.x releases will go into critical fixes only mode.
Consult the EOL [18]policy for more details.
We would also like to mention that with the 4.5 release we stopped
supporting systems using 32-bit time. This includes many 32-bit Linux
platforms.
We are grateful to the PowerDNS community for the reporting of bugs,
issues, feature requests, and especially to the submitters of fixes and
implementations of features.
- Otto and the PowerDNS Team
