Today we have released a maintenance release of PowerDNS Recursor 4.5.12, 4.6.5 and 4.7.4, containing fixes for a few minor issues. In particular, RPZ IXFRs now time out if the server becomes unresponsive. For more details on the other fixes, consult the changelogs available at 4.5.12, 4.6.5, 4.7.4.
Note that PowerDNS Recursor 4.4.x and older releases are End of Life. Consult the EOL policy for more details.
We would also like to repeat that starting with the 4.5 release branch we stopped supporting systems using 32-bit time. This includes most 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.
