@Camelot: Erm, no, really no, no and no. No way - that would be the nearly dumbest move one can make. Please have a look at the changelog. After that please ask yourself some questions:
1. Wtf is testing 62.x
2. Why do newer versions never made it to testing?
3. Is chromium/unstabe in the current state really a good idea?
I'm not argueing against FOSS - i'm argue against versions of software with many CVEs open. So - never suggest or use testing when chromium breaks - use the latest working versions from snapshots. And check the changelog if even that downgrade could be considered as a really good idea.
