Browser Support for mobile and desktop is out of date
Closed, ResolvedPublic


Where browser usage is over 5% a modern experience (Grade A) is supported.
Grade A browser list on MobileFrontend is defined in .browserlistsrc file.

Looking at only 12 and 13 are over 5%; 11 is 2.2%, 10 is 1.3%, 9 is 0.87% says ios 6.0

Similarly, only Android 6.0 is > 5%, with Android 5.0 at 3.1% and 4.0/4.1 absent completely says android 4.1

The ios version in .browserslistrc also doesn't agree with (6.1 vs 6.0)

Event Timeline

iOS 9+ and Android 4.4 (ish) are required for Wikimedia sites due to the TLS 1.0/1.1 deprecation, so it would be impossible for iOS 6-8 to show up in the analytics. While older versions might still be supported elsewhere, I think that's a good hint to downgrade them officially in MobileFrontend.

@ovasileva now might be a good time to check these (along with revisiting the same for desktop)

Apparently a conversation around this is happening elsewhere which Olga is keeping an eye on.

@ovasileva did this conversation get any resolution?

MobileFrontend is now using Wikimedia central 'browserslist-config-wikimedia', (T282779). Per extension overrides are still possible. Setting on “resolved”
