SNS Update: Feb 9, 2024

The NNS Team will be submitting the following proposals to publish new versions of SNS canisters to SNS-WASM this Friday, 2024-02-09. DFINITY plans to vote on these proposals the following Monday.

Additional Notes / Breaking Changes

Recall from the recent issue that the SNS root used to set the memory limit of all canisters it upgraded to 1GiB.
This behavior has been changed in 127516 and from now on a normal upgrade will not change a canister’s memory allocation.
However, all canisters that already have a low memory allocation from past upgrades, still keep this limit.
This could be especially risky for SNS canisters - as it would be even harder to recover if an SNS canister runs out of memory, especially governance.
Therefore, this upgrade includes a change that will, in a one-off, set the memory allocation of all SNS canisters to best effort.
Note that this does not include the SNS-controlled dapp canisters. SNS communities should be aware that the SNS-controlled dapp canister might have the 1GiB limit that was assigned on every SNS upgrade. However, since proposal 127674, SNS DAOs can adjust these limits by proposal.

My apologies. I accidentally posted the proposal text for NNS governance when I meant to post the proposal text for SNS governance. The actual proposal was correct:

This could lead to dapp canisters running out of memory when they reach the 1GB reserved memory allocation. Please check your memory allocation, using the get_sns_canisters_summary (BoomDAO example) method, and change the memory allocation using a UpdateDappCanisterSettings proposal if necessary.
