### Proposer: DFINITY Foundation
### Git Hash: 1fd18580dbca83d418e1e55d490074b7195aa606
### New Wasm Hash: 07c584821cc2c4a7d1a23c31f2337eb66bc46dbd470e15e01c6d530e30cd7c0d

(Submitted by Daniel Wong on Behalf of Arshavir Ter-Gabrielyan.)
---
## Features
* Removing some Registry functions that were only callable by NNS Governance but are no longer used:
    * `retire_replica_version`
    * `update_subnet_replica_version`
    * `bless_replica_version`
* Added some Registry functions that are named consistently w.r.t. The new IC OS upgrade proposal names, without adding any new functionality:
    * `revise_elected_guestos_versions`
    * `revise_elected_hostos_versions`
    * `deploy_guestos_to_some_api_boundary_nodes`
    * `deploy_hostos_to_some_nodes`
