Hi everyone,
the Design System Team (DST) is proposing the following changes to MediaWiki browser support [1]:
- Drop support for Internet Explorer 11 (IE 11)
- Drop support for all versions of Edge Legacy
- Drop support for Opera
- Increase Basic (Grade C) support for Chrome and Firefox to versions 49+, Safari and iOS to versions 10+.
What this means: The browsers we’re phasing out won’t be tested for layout rendering
anymore. While users on these browsers might and will still be able to read and basically interact with
content, they might experience some quirks. This step helps us integrate
modern web features more seamlessly.
These changes will unlock the ability to use specific newer browser features that cannot be safely used today without requiring a fallback, notably CSS custom properties (used in upcoming reading customization features like Night Mode) and the <summary> and <details> HTML elements that can be used to replace the checkbox hack.
This will reduce the amount of code sent to 99.9% of users and cut down on software development costs and maintenance burdens.
See the full announcement for more details; PDF to download [2].
On behalf of the Wikimedia Foundation Design System Team,
