## Hotfix
An upgrade proposal on Nov 20 caused NNS Governance heartbeats to hit the instruction limit.  After rolling this back, it was discovered that some neurons were not able to finish spawning. The issue in heartbeats created a permanent lock on spawning, and caused one neuron to be locked.  After investigating, all neurons were shown to have correct values, meaning it is safe to rest the Neuron Spawning lock and to unlock the single affected neuron.

This release only patches the currently deployed version of NNS Governance (which was rolled back to late November 20th), and does not contain other changes.

This release is built from branch hotfix-no-rc--nns-2023-11-20, and these changes will not be merged back into the master branch, as they only need to be executed once.
