If the `manual` parameter is assigned a date in the form of
`YYMMDD`, this will tell uBO to update lists from origin sources
when the current time is within the range of the specified date,
otherwise lists will be updated from CDNs. Updating from CDNs
is always strongly recommended since this enables differential
updates.
For the time being, `manual=1` will always cause to update lists
from origin, but this form will be deprecated once next stable
release is widespread. The idea is to not leave behind stale
and obsolete links which would be detrimental to differential
updates should someone click on one of these old links left
behind.
Broadcast channels are more suited to uBO than DOM events to dispatch
notifications to different parts of uBO.
DOM events can only be dispatched to local context, broadcast channels
dispatch to all contexts (i.e. background process, workers, auxiliary
pages) -- this last behavior is better suited to uBO to communicate
internal changes to all potential listeners, not just those in the local
context.
Additionally, broadcasting to content scripts is now done through
tabs.sendMessage() instead of through potentially opened message
ports, this simplifies broadcasting to content scripts, and this
doesn't require to have long-lived message ports in content
scripts.
As per discussion with uBO volunteers.
Volunteers offering support for uBO will be able to craft links with
specially formed URLs, which once clicked will cause uBO to automatically
force an update of specified filter lists.
The URL must be crafted as shown in the example below:
https://ublockorigin.github.io/uAssets/update-lists.html?listkeys=ublock-filters,easylist
Where the `listkeys` parameter is a comma-separated list of tokens
corresponding to filter lists. If a token does not match an enabled
filter list, it will be ignored.
The ability to update filter lists through a specially crafted link
is available only on uBO's own support sites:
- https://github.com/uBlockOrigin/
- https://reddit.com/r/uBlockOrigin/
- https://ublockorigin.github.io/
Additionally, a visual cue has been added in the "Filter lists" pane
to easily spot the filter lists which have been recently updated, where
"recently" is currently defined as less than an hour ago.

If there exist any built-in filter list which last update time
is older than 2 hours, the "Report a filter issue" page will ask
the user to update their filter lists then verify that the issue
still exists.
Once filter lists are updated, the troubleshooting information
will reflect the change in update time.
These two new pseudo selectors are _action_ operators, and thus can
only be used at the end of a selector. They both take as argument
a string or regex literal.
For `:remove-class()`, when the argument matches a class name, that
class name is removed.
For `:remove-attr()`, when the argument matches an attribute name,
that attribute is removed.
These operators are meant to replace `+js(remove-attr, ...)` and
`+js(remove-class, ...)`, which from now on are candidate for
deprecation in some future.
Once the next stable release is widespread, filter authors must use
these two new operators instead of their `+js()` counterparts.
`uDom` is old and crusty and `dom` is meant as replacement. The
goal of `dom` is to be simpler and mainly just convenience
methods for handling the DOM with vanilla JS -- this is not a
framework.
Additionally, removed keyboard shortcuts pane which was useful
only on very old versions of Firefox.
This fixes https://github.com/uBlockOrigin/uBlock-issues/issues/2240 and
should get the desired behavior regardless of browser.
