what is the difference between ESP-IDF version release/4.2 and release/4.4

[kesha.modhia]

want to know the key difference of esp-idf versions release/4.2 and release/4.4

I have checked compare section but it is little bit difficult to identify so need a brief detail of that what's new in release 4.4 ex. bug fixes, implementation

We have release notes for every release we do. You could look up the release notes for the original 4.3 and 4.4 releases; that should give a good indication of the major changes.
