Hockeypuck 2.3.1 released

[Andrew Gallagher]

Hi, all.

We are pleased to announce the release of Hockeypuck 2.3.1.

Hockeypuck 2.3.1 is primarily a bugfix and maintenance release:

* Fix broken delete-keys helper script
* Bumped dependencies and refactored redundant code paths
* Improved PKS support
* Config parameter to increase the number of results returned from a search

There are no breaking changes between the 2.2 and 2.3 branches, and SKS
sync is supported between 2.2 and 2.3 peers.
