Last night a new revision of 2.28 was pushed to the candidate channel. The snapd version is 2.28.5.
But the most important change in this release is the updated wpasupplicant package that fixes the recent wifi “krack” CVEs. In addition to this security update we also fixed support for the latest nvidia drivers and fixed an incorrect rule in the network-control interface.
