Governance

# Publish SNS Governance WASM Built at Commit 4b7cde9

__Proposer__: jason.zhu at dfinity.org

__Source code__: [4b7cde9a0e3b5ad4725e75cbc36ce635be6fa6a8][new-commit]

[new-commit]: https://github.com/dfinity/ic/tree/4b7cde9a0e3b5ad4725e75cbc36ce635be6fa6a8

## Features & Fixes

###  Added

RegisterExtension proposals can now be used in the test version of SNS Governance; submitting
these proposals on mainnet is still disabled until further notice.


###  Fixed

Fixed a bug due to which governance cached metrics could be recomputed once every 10 seconds
rather than with the intended rate of once per hour.

Thanks for calling it out. The link generation for NNS proposals was improved but it missed the ones for SNS proposals. Should be better the next time
.

Note: DFINITY is planning to reject 137585-137587 because they are at a commit newer than intended

Update: 137585-137587 are rejected.
