(via: https://blog.powerdns.com/2019/05/07/powerdns-recursor-4-2-0-beta-1-released/ )

The Beta 1 release comes with a lot of bug fixes, improvements and also some new features:

- Add a new `max-cache-bogus-ttl` option to cap the TTL of a record that has been validated as `Bogus` in the query cache, so it is not kept around for days if the initial TTL is high,

- Add options `dont-throttle-names` and `dont-throttle-netmasks` to throttle authoritative servers that do not answer queries or send responses the recursor does not like,

- Add an option (`pdns-distributes-queries`) to make the distributor thread use a bounded load-balancing algorithm while distributing queries to worker threads, making sure that no thread is assigned more queries than `distribution-load-factor` times the average number of queries currently processed by all the workers.

Please see the changelog[1] for details.

This release was made possible by contributions from: Aki Tuomi, Chris Hofstaedtler, Shane Kerr and Sebastian.
