Barring any catastrophic bugs in this release, this will be the last release in the 3.2.x line. The next release, 3.3.0, will begin emitting DeprecationWarnings when the pre-PEP8 methods are used (see header notes above for more information, including available automation for converting any existing code using pyparsing with the old names).

• Fixed bug when using a copy of a Word expression (either by using the explicit copy() method, or attaching a results name), and setting a new expression name, a raised ParseException still used the original expression name. Also affected Regex expressions with as_match or as_group_list = True. Reported by Waqas Ilyas, in Issue ParseElement.copy() result refers to previous instance #612 - good catch!

• Fixed type annotation for replace_with, to accept Any type. Fixes Issue replace_with has incorrect argument typing #602, reported by esquonk.

• Added locking around potential race condition in ParserElement.reset_cache, as well as other cache-related methods. Fixes Issue Concurrency issue on Cache when packrat is enabled. #604, reported by CarlosDescalziIM.

• Substantial update to docstrings and doc generation in preparation for 3.3.0, great effort by FeRD, thanks!

• Notable addition by FeRD to convert docstring examples to work with doctest! This was long overdue, thanks so much!
