Hi all,

We've just shared a blog post on the Chromium blog about the start of the Manifest V2 phase-out: https://blog.chromium.org/2024/05/manifest-v2-phase-out-begins.html

At the same time, we've posted on developer.chrome.com announcing the option to skip review for eligible Declarative Net Request changes: https://developer.chrome.com/blog/extensions-skip-review-eligible-changes

Thanks,
Oliver on behalf of Chrome Extensions DevRel

> Now, over 85% of actively maintained extensions in the Chrome Web Store are running Manifest V3

In other words 15% of actively maintained extensions are ManifestV2 and the article conveniently sidesteps the issue effectively implying that it doesn't matter, but 15% sounds like a lot, especially since many (maybe most?) of them don't have a comparable alternative e.g. uBlock Origin's flexibility of ad blocking is unmatched as well as Stylus's support of dynamically configurable UserCSS userstyles. Personally I'll keep using them for the next year by setting the ExtensionManifestV2Availability policy and if nothing comparable comes along I'll have to consider switching the browser.

> the top content filtering extensions all have Manifest V3 versions available - with options for users of AdBlock, Adblock Plus, uBlock Origin and AdGuard.

The article also conveniently forgets to mention that these options are severely limited compared to the ManifestV2 version of uBlock Origin.

over 85% of actively maintained extensions in the Chrome Web Store are running Manifest V3

According to this site, 45% of the web store is still on MV2.
The fact that an extension hasn't been updated recently doesn't mean it's useless. I, for example, use an extension that was last updated in early 2023 and another in 2022. This is what's called the "long tail" in the chart. i.e. a large amount of extensions with small amount of users, which, when combined, amount to a lot of users.

I would be interested in seeing how “actively-maintained” is defined; Controlling the definition of that phrase, you can tell whatever story you want to tell.

By the same token, I’d be interested in knowing what percentage of extension on CWS are considered “not actively maintained”, and would be interested to see what kind of overlap that has with “actively used”.
