Snapshot 1.3.544.25 - Quick fixes
Sorry for the stupid question but what is a "snapshot"? Is that some kind of a beta version?
A Snapshot is some kind of a beta version.
Opera have three channels called Developer, Beta, and Final.
Vivaldi has only two channels: Snapshots and Finals. When a Snapshot is nearly ready for release as a Final version, they name it as a Release Candidate.
If you use the Final version, check for updates won't find the latest Snapshots.
