The rollout of the latest replica version is proceeding without any issues. We can already see a huge improvement in the manifest computation of our state manager with the latest release. This chart shows the difference in one of our subnets with a huge state size before and after the version upgrade:

These changes are now available for testing in dfx 0.8.5, which has been released but not promoted. To install 0.8.5 now, you can use the command

DFX_VERSION=0.8.5 sh -ci "$(curl -fsSL https://smartcontracts.org/install.sh)"

Last minute we got a minor hotfix in that needs to be rolled to the k44fs app subnet that has a running incident.
Still a good release. The bug existed since Genesis.
Expect a new proposal soon electing a new replica version.

The rollout of this replica version was completed yesterday by the upgrade of the NNS subnet.
The next RC is already announced and currently qualified.
