NNS updates: Sept 20, 2023

Developers

The NNS Team will be submitting the following upgrade proposals this Friday, 2023-09-22. DFINITY plans to vote on these proposals the following Monday.

Upcoming in a future release

1-Proposal

Good news! 1-proposal, a project to simplify the creation of SNSes, went live at the end of August. Now that it’s been tested in the wild, DFINITY plans to submit a proposal to disable the old 2-proposal flow in the coming weeks. DFINITY is aware of no upcoming SNSes with plans to use the two-proposal flow, but leave a comment if this affects you.

Breaking Changes

Lifeline

Note that the proposal contains a breaking change in the lifeline canister.

Who it affects:

  1. Users of Lifeline’s canister_status api.

The change:

  1. controller was removed from the return type of canister_status as it has invalid semantics (canisters can have multiple or zero controllers). Instead, the field settings::controllers should be used to get a canister’s controllers.

How to prevent breakage:

  1. Do not use controller. Instead, to get the canister’s controllers, use settings::controllers.
