I'm a little confused. Of the commits linked which seem to be the "breaking changes", two seem to be entirely documentation updates that are 90% changing the title casing.
The remainder seem to be around updating the pipeline/other files to specify support for php 7.2-7.4 instead of 7.4+8.0 and a bunch of other documentation (phpdoc) changes.
What are the drastic breaking changes thusfar?
