2 months ago @Antonio-Laguna This has been open for some time and I haven't encountered any other spec changes that require a breaking change.
This change would be limited to the changes in nesting and a bump of our minimum node version.
Is there any thing you would still like to change?
If not, I suggest we ship this next week 🚀
We shipped 9.0.0 around 2023-07, so that gives us a nice interval.
A good explanation for the aspect of nesting that was most recently changed can be found here: https://drafts.csswg.org/css-nesting/#nested-declarations-rule%E2%91%A0
We eagerly added support for this in the 2024-02 edition, even when it had not yet landed in the spec text (https://github.com/csstools/postcss-plugins/pull/1305)
I am choosing not to re-order declarations and nested rules in this new edition because we actually know that this is a major pain point and I want to give users hands on experience with what it could be if https://github.com/w3c/csswg-drafts/issues/8738 is adopted.
With the recent spec edits our 2024-02 editions aligns with https://drafts.csswg.org/css-nesting/
noIsPseudoSelectorforpostcss-nesting. This option is no longer relevant for the latest CSS specification.
