See Coconut's documentation for more information on all of the features listed below.

Language features:

• Shorthand for match assignment functions #833: New case def syntax for more easily defining pattern-matching functions with many patterns.
• Match keyword argument name elision syntax to whatever is adopted in Python #811: New f(name=) syntax as a shorthand for f(name=name), replacing the now deprecated f(...=name) syntax.
• Add CoconutWarning for all Coconut runtime warnings #836: New CoconutWarning built-in used for Coconut runtime warnings.

Compiler features:

• --strict should disallow implicit string concatenation #837: Coconut will now warn about implicit string concatenation and disable it completely with --strict.
• addpattern def with no prior match def #718: Coconut will now warn about use of addpattern def without a prior match def. This was a previously-supported feature to make pattern-matching functions with many patterns easier to write, but the new recommended way to do that is now via case def.
• Add proper pyright support #785: Initial pyright support via the --pyright flag.

Bugfixes:

• Some f-strings don't parse correctly #839, Wrong f-string parsing and compile warning #840: Fixed some f-string parsing issues.
• Empty zip objects error on __len__ #834: Fixed len of empty zip objects.
• When to output colors handled incorrectly #830: Improved use of colored output.
• Fully support PEP 695 #757: Improved PEP 695 support on Python 3.12.
