This is the 5.4.6.0 leisure release, the final release in the Miss Piggy milestone.

This is an important release that contains a number of bugfixes that enhance stability for the wallet and implement poll caching, automatic background updates and performance improvements for polls/voting. It also includes most of the basic machinery needed to support the v13 block version protocol which will be in the next mandatory at the following milestone, Natasha, although the v13 block height has not been set, so we remain at v12 for now.
