This is similar to the removed `top-enabled` option but for the Popular feed.
The instance needs to be restarted if the feed was enabled.
Editing admin options on the preferences page is also fixed.
The handling of the feed pages now only happens in a single place.
Instead of redirecting:
- The Top feed now displays a message that it was removed from Invidious.
- The Popular feed now displays a message that it was disabled if it was.
The Top feed used to be a feed based on YouTube ratings. Once YouTube removed
publicly available ratings the Top feed was removed from Invidious but the
option to display a link to it remained.
Besides `auto`, `best` and `worst` it is now possible to select a target height.
If the target height is not available the closest lower height is selected.
* shard: update to crystal 0.31.0
Additionally, no longer use the Crystal "markdown" library which has
been removed from the Crystal stdlib in version 0.31.0.
See https://github.com/crystal-lang/crystal/pull/8115.
Also fix some deprecation warnings using the following commands:
find . \( -type d -name .git -prune \) -o -type f -exec sed -i 's/URI\.escape/URI\.encode_www_form/g' "{}" \;
find . \( -type d -name .git -prune \) -o -type f -exec sed -i 's/URI\.unescape/URI\.decode_www_form/g' "{}" \;
sed -i 's/while \%pull\.kind \!\= \:end_object/until \%pull\.kind\.end_object\?/g' src/invidious/helpers/patch_mapping.cr
* Add prefers-color-scheme support
This should fix <https://github.com/omarroth/invidious/issues/559>.
The cookie storage format has been changed from boolean
("true"/"false") to tri-state ("dark"/"light"/""), so that users
without a cookie set will get dark mode if they have enabled the dark
theme in their operating system. The code for handling the cookie
state, along with the user's operating system theme, has been factored
out into a new function `update_mode`, which is called both at window
load and at the "storage" event listener, because the "storage" event
listener is only trigerred when a change is made to the localStorage
from another tab/window (for more info - see
<https://stackoverflow.com/a/4679754>).
