alt Hacker NewsThey said "we have started disabling Manifest V2 extensions on pre-stable channels", and the "Chrome canary" referenced in the submission title is a pre-stable channel. The submission title is accurate, but narrowly highlighting only one facet of Google's update statement.
That's old news, as noted in my other comment: https://news.ycombinator.com/item?id=41810420
The change here is actually about the stable channel.
Also, the title makes it sound like MV2 code has been removed from the source, but that's not the case.
