## Summary

**Important:** The compile format of filter lists has changed, and this means upon update uBO will have to recompile all filter lists, so this may cause a longer delay at launch the first time uBO is launched after being updated. This is a one time event.

The cloud storage feature has been improved in a number of ways:
- Better reporting of error conditions in the user interface;
- User interface widget to report storage used/total/max;
- Support for compressing cloud storage data.

Improved _"My rules"_ user interface:
- Ability to sort rules by type, source, or destination;
- Ability to show changes only.

Added support to chain `:style(...)` operator to procedural operators.

The element picker has been refactored to fix long standing issues (including some not reported in the issue tracker). The <kbd>Ctrl</kbd> key is no longer used to control the specificity of a candidate filter, and new widgets have been introduced for the purpose of more easily tuning the depth and specificity.

The click-to-subscribe feature has been reworked and is now allowed only on a select number of domains, currently: <https://easylist.to/>, <https://fanboy.co.nz/>, <https://filterlists.com/>, <https://forums.lanik.us/>, <https://github.com/>, <https://github.io/>.

The concept of "bad list" has been introduced, to prevent users from unwittingly end up using what are deemed ["bad lists" by the uBO team](https://github.com/uBlockOrigin/uAssets/blob/master/filters/badlists.txt). Some "bad lists" will be completely ignored and importing them will be forbidden by uBO. This restriction can be bypassed by users by simply appending a dummy query parameter to the URL of the list.
