Sourced from pyparsing's releases.

Pyparsing 3.1.2

• Support for Python 3.13.

• Added ieee_float expression to pyparsing.common, which parses float values, plus "NaN", "Inf", "Infinity". PR submitted by Bob Peterson (#538).

• Updated pep8 synonym wrappers for better type checking compatibility. PR submitted by Ricardo Coccioli (#507).

• Fixed empty error message bug, PR submitted by InSync (#534). This should return pyparsing's exception messages to a former, more helpful form. If you have code that parses the exception messages returned by pyparsing, this may require some code changes.

• Added unit tests to test for exception message contents, with enhancement to pyparsing.testing.assertRaisesParseException to accept an expected exception message.

• Updated example select_parser.py to use PEP8 names and added Groups for better retrieval of parsed values from multiple SELECT clauses.

• Added example email_address_parser.py, as suggested by John Byrd (#539).

• Added example directx_x_file_parser.py to parse DirectX template definitions, and generate a Pyparsing parser from a template to parse .x files.

• Some code refactoring to reduce code nesting, PRs submitted by InSync.

• All internal string expressions using '%' string interpolation and str.format() converted to f-strings.
