Before 2021-04-20, LanguageTool only knew PRP (like ‘I’, ‘me’, ‘myself’) and PRP$ (like ‘my’ and ‘mine’). Now, you can distinguish more precisely and synthesize one form from another (e.g. ‘I’ from ‘myself’).
This change has one immediate impact: If you want to negate the postag PRP, you’ll now have to negate PRP(_.*)?. If you want to negate the postag PRP\$, you’ll now have to negate PRP\$(_.*)?.
Example:
Before:
<token postag="PRP"><exception postag="PRP" negate_pos="yes"/></token>
Now:
<token postag="PRP"><exception postag="PRP(_.*)?" postag_regexp="yes" negate_pos="yes"/>
Also: If you want to write an exception for PRP (or PRP\$), you might have to use PRP(_.*)? (or PRP\$(_.*)?) for the exception to work.
If you use the new postags to convert, e.g. an object pronoun to a possessive pronoun, there is a conflict with the interpretation of the $ no matter if you escape it or not.
These two ways of writing it will make the test fail:
<match no="3" postag="PRP_O(.*)" postag_replace="PRP$_P$1" postag_regexp="yes"/>
<match no="3" postag="PRP_O(.*)" postag_replace="PRP\$_P$1" postag_regexp="yes"/>
This is how you make it work:
<match no="3" postag="PRP_O(.*)" postag_replace="PRP._P$1" postag_regexp="yes"/>
→ use a . instead of the contentious $ sign. It’s unambiguous in that position anyway.
Rule of thumb: Inexplicable build fails can go away if you replace \$ or $ with ..
The last 2 or 3 characters in these tags refer to person [123], number [SP], and, if applicable, gender [MFN].
E.g., ‘her’ is an object pronoun (PRP_O.*) and the last 3 characters are 3SF, so the complete tag is PRP_O3SF.

There is a new level of distinction for PRP$ as well. We distinguish “adjective-like” possessives (e.g. ‘my’) and proper “possessive pronouns” (e.g. ‘mine’).
