The Governance Team submitted the following proposals. DFINITY plans to vote on these proposals the following Monday.
SNS Root
# Publish SNS Root WASM Built at Commit 7ab1889
__Proposer__: shahriar.javidi at dfinity.org
__Source code__: [6ab18899e82ac202fea4a549dcc6c5a5191e4992][new-commit]
[new-commit]: https://github.com/dfinity/ic/tree/6ab18899e82ac202fea4a549dcc6c5a5191e4992
## Features & Fixes
SNS Root now has a function called `register_extension` that is similar to `register_dapp_canister`,
but different in the following ways:
* The controllers of an SNS extension are the Root and the Governance canisters of the SNS (as
opposed to just Root). This allows SNS Governance to call functions of the extension that can
be called only by an extension\'s controller.
* Extensions are listed separately in the respone of `list_sns_canisters`.
Similar to `register_dapp_canister` and `register_dapp_canisters`, `register_extension` can be
called only by the SNS Governance.

SNS Governance
# Publish SNS Governance WASM Built at Commit 6ab1889
__Proposer__: shahriar.javidi at dfinity.org
__Source code__: [6ab18899e82ac202fea4a549dcc6c5a5191e4992][new-commit]
[new-commit]: https://github.com/dfinity/ic/tree/6ab18899e82ac202fea4a549dcc6c5a5191e4992
## Features & Fixes
SNS Governance has initializes the extensions via an ICRC-2 flow; instead of directly
transferring tokens to the extension, it grants an allowance for the extension and then calls into
the extension which can claim the tokens by an `icrc2_transfer_from`. In this way, if the initialization
of the extension fails, tokens are not stuck there and the proposal can be retried.
