+clean-css-cli 4.3 introduces the following changes / features:
 
-* API and CLI interfaces are split, so CLI has been moved to this repository while API stays at [clean-css](https://github.com/jakubpawlowicz/clean-css);
-* `--root` and `--relativeTo` options are replaced by a single option taken from `--output` path - this means that rebasing URLs and import inlining is much simpler but may not be (YMMV) as powerful as in 3.x;
-* `--rounding-precision` is disabled by default;
-* `--rounding-precision` applies to **all** units now, not only `px` as in 3.x;
-* `--skip-import` and `--skip-import-from` are merged into `--inline` option which defaults to `local`. Remote `@import` rules are **NOT** inlined by default anymore;
-* renames `--timeout` option to `--inline-timeout`;
-* remote resources without a protocol, e.g. `//fonts.googleapis.com/css?family=Domine:700`, are not inlined anymore;
-* changes default Internet Explorer compatibility from 9+ to 10+, to revert the old default use `--compatibility ie9` option;
-* moves `--rounding-precision`, `--s0`, and `--s1` options to level 1 optimization options, see examples;
-* moves `--skip-media-merging`, `--skip-restructuring`, `--semantic-merging`, and `--skip-shorthand-compacting` to level 2 optimizations options, see examples below;
-* level 1 optimizations are the new default, up to 3.x it was level 2;
-* `--keep-breaks` option is replaced with `--format keep-breaks` to ease transition;
-* `--skip-aggressive-merging` option is removed as aggressive merging is replaced by smarter override merging.
