| - Difference in pseudo signature just prevents ruleset merging, but don't stop lookup. |
| - Simplify block comparison (performance). |
| - New method `csso.minifyBlock()` for css block compression (e.g. `style` attribute content). |
| - Ruleset merge improvement: at-rules with block (like `@media` or `@supports`) now can be skipped during ruleset merge lookup if doesn't contain something prevents it. |
| - FIX: Add negation (`:not()`) to pseudo signature to avoid unsafe merge (old browsers doesn't support it). |
| - FIX: Check nested parts of value when compute compatibility. It fixes unsafe property merging. |
