version 20.2.0.30 claims to solve the "[ID-4243320] Incorrect Cursor movement in right-to-left text within InDesign when composed using
Harfbuzz shaper" bug. unfortunately, it's still not working well. this bug is also listed under [ID-4246352]
up untill version 18.5, when selecting a letter with a diacritic in hebrew, the selection marker would indictae if the letter AND the diacritic is selected, or just one of them. but currently, under harfbuzz shaper, selecting a letter and a dicaritic looks exactly like selecting it without the diacritic. and this way you can't act just on part of the letter-diacritic combination. it may sound unimportant but actually in Hebrew we make a lot of formats on the diacritics alone, so it's critical.
to repeat the bug, write a letter in hebrew and add one or two diacritics. say: נֵּ
now try to select just the first diacritic (dagesh) or the second (kamatz) - you'll see it's like the whole letter is selected.
but this is how it looked back in version 18.5 (which most designers in hebrew still use due to all the bugs in newer versions):
selecting one diacritic:

selecting two diacritics:

selecting two diacritics AND the letter itself:

This is a serious bug, and it prevents proper work with Hebrew.

This has become a significant problem in our daily work. We have a large number of books being published constantly, and now it has become impossible to work with this issue. Our company cannot use the 2025 version. We have around 30 employees affected by this. Please fix it and revert it to how it was before.
