v3.2.3

This patches an edge case bug introduced in v3.2.0 which could be encountered when a cosigner has downtime. The leader could get stuck, causing signing to stop even with threshold cosigners online.

Updating

If coming from v3.2.0-v3.2.2, this can be applied as a rolling upgrade, which prevents missed blocks:

• Shut down a non-leader cosigner, upgrade version, and restart
• Repeat for remaining non-leader cosigners
• elect one of the upgraded cosigners as the leader with horcrux elect N
• Shut down the initial leader cosigner, upgrade version, and restart
• elect initial leader as leader again if desired

If coming from ≤v3.1.0:

• Shut down all cosigners and delete ~/.horcrux/raft directory
• Update binary or docker image
• Start cosigner nodes back up

What's Changed

• Fix stuck leader when cosigner goes down by @agouin in #232
• Reverse where we start checking for a non-expired nonce, oldest -> newest by @misko9 in #234
• add unit tests for prune by @agouin in #235
• mitigate unexpected state by @agouin in #233

New Contributors
