This scriplet supersedes abort-current-inline-script (acis),
and accepts an optional third argument which is matched
against the `src` property of script resources.
When the third argument is not provided, the scriptlet
behaves essentially the same as `acis`, and because of
this `acis` is now aliased to `abort-current-script`, and
all existing `acis` filters will execute with no change
in behavior.
In the long run, usage of `abort-current-inline-script` or
its alias `acis` should go away and be replaced with
`abort-current-script` or its alias `acs`.

This commit ensures FLoC is opt-in. The generic filter
`*##+js(no-floc)` in "uBlock filters -- Privacy" ensures
the feature is disabled when using default settings/lists.
Users can opt-in to FLoC by adding a generic exception
filter to their custom filters, `#@#+js(no-floc)`; or they
can opt-in only for a specific set of websites through a
more specific exception filter:
example.com,shopping.example#@#+js(no-floc)

A third (optional) argument has been added to `remove-attr`
scriptlet, which can be one or more space-separated tokens
dictating the behavior of the scriptlet:
`stay`: This tells the scriplet to stay and act on DOM
changes, whiĺe the default behavior is to act only once
when the document becomes interactive.
`complete`: This tells the scriplet to start acting only
when the document is complete, i.e. once all secondary
resources have been loaded, while the default is to start
acting when the document is interactive -- which is earlier
than when the document is complete.
Example:
...##+js(remove-attr, class, .j-mini-player, stay)
When no-fetch-if scriptlet is used without argument, the
parameters passed to no-fetch-if will be output to the
console, as `uBO: fetch([...list of arguments...])`.
The new scriptlet allows to defuse calls to fetch() by returning
a promise which always resolve to an empty response.
There is only one argument, which is a space-separated list
of conditions which must be ALL fulfilled in order for the
defusing to take place.
Each condition is a pair of property name and property value
separated by a column. Valid property names are those
documented as valid `init` options:
https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/fetch
The URL of the fetch() is a special case and does not have to
be associated with a property name. Example of usage:
...##+js(no-fetch-if, method:HEAD)
Which means: defuse the call to fetch() if there is an
explicit option which contains `HEAD`. Another example:
...##+js(no-fetch-if, adsbygoogle.js)
Which means: defuse the call to fetch() if the URL contains
`adsbygoogle.js`. Multiple conditions can be provided:
...##+js(no-fetch-if, adsbygoogle.js method:HEAD)
If at least one condition does not match, the defusing will
not take place.
The string against which to match can be a literal regular
expression:
...##+js(no-fetch-if, /adsbygoogle.js$/ method:/HEAD|POST/)
Additonally, the following deprecated scriplets have been
removed:
- requestAnimationFrame-if.js
- setInterval-defuser.js
- setTimeout-logger.js
This new scriplet has become necessary as a
countermeasure to new bypass mechanisms by
some websites, as discussed with filter list
maintainers.

Scriptlet: abort-on-stack-trace
Alias: aost
Argument 1:
The property to trap in order to launch the
stack trace matching code, ex. Math.random
Argument 2:
The string (needle) to match against the stack
trace. If the empty string, always match. There
is a special string which can be used to match
inline script context, <inline-script>.
Argument 3:
Whether to log, and if so how:
Empty string: do not log
1: log stack trace for all access to trapped
property
2: log stack trace for defused access to trapped
property
3: log stack trace for non-defused access to
trapped property
Reported internally by team.
Explicit conversion was causing an exception to be
thrown when the type argument was not supporting
`toString()`, for example when `type` argument was
literal `null`.
Add support for specially-named properties:
`[]`, to iterate through all elements in an array, in
order to deal more graciously with cases where the
property to remove is an element in an array. An
actual case:
+js(json-prune, playlist.movies.0.adserver playlist.movies.1.adserver ...)
Can be now converted to:
+js(json-prune, playlist.movies.[].adserver)
`*`, to iterate through all own properties of an object,
in order to deal with random-named properties. For
example (not an actual case):
+js(json-prune, playlist.*.adserver)
Where `adserver` would be a property member of an
object which is itself a property of `playlist`, but
which name is unknown or is variable.
Specifically:
- Log entries as received by client code
- Prettier and more readable console output
- Ability to only log entries matching a
specific needle
As per internal discussion at
<https://github.com/uBlockOrigin/uAssets>; limited
logging capabilities of json-prune originally raised
by <https://github.com/gwarser>.

To be consistent with no-setTimeout-if.js.
requestAnimationFrame-if.js is deprecated and must no longer be
used, it will be removed in the near future when it's no longer
in use in default filter lists.
no-requestAnimationFrame-if.js is aliased to norafif.js.
