Thanks Carlton Gibson, Chris Jerdonek, David Smith, Keryn Knight,
Mariusz Felisiak, and Nick Pope for reviews and mentoring this
Google Summer of Code 2021 project.
Defined all colors used in the admin CSS as variables. Implemented the
following standardizations and accessibility improvements while at it:
- Improved the contrast of text to not use ratios of less than 3:1 anymore.
- Most hover states already used desaturated and darkened colors.
Changed object tools to follow the same rule instead of showing the
primary color on hover.
Various places used similar colors; those have been merged with the goal
of reducing the count of CSS variables. Contrasts have been improved in
a few places.
- Many borders used slightly different colors (e.g. #eaeaea vs. #eee)
- Help texts used #999, this has been changed to --body-quiet-color
(#666) which has a better contrast.
Introduced fast color transitions on links and buttons.
SecurityMiddleware and the three cache middlewares were not calling
super().__init__() during their initialization or calling the required
MiddlewareMixin._async_check() method.
This made the middlewares not properly present as coroutine and
confused the middleware chain when used in a fully async context.
Thanks Kordian Kowalski for the report.
Following web standards, the modern _evergreen_ browsers are all
supported. This applies equally to mobile platforms. Assuming current
trends continue, this should be a sustainable policy.
Microsoft deprecated all versions of Internet Explorer. IE 11, the last
version, is described as a "compatibility solution" rather than a web
browser. Whilst it will receive security updates for the lifetime of
Windows 10 it's use is actively discouraged.
The IE 11 downloads page makes it clear: "We recommend you use the new
Microsoft Edge".
These classes can serve as a base class for user enums, supporting
translatable human-readable names, or names automatically inferred
from the enum member name.
Additional properties make it easy to access the list of names, values
and display labels.
Thanks to the following for ideas and reviews:
Carlton Gibson, Fran Hrženjak, Ian Foote, Mariusz Felisiak, Shai Berger.
