+
+2024-10-25
+
+A bugfix release for Teal 0.24. Several fixes that bring the implementation
+closer to the vision of what the 2024 edition is intended to be, thanks to
+the invaluable feedback of the user community!
+
+This release features commits by François Perrad, Steve Vermeulen and
+Hisham Muhammad.

+  * Ignore non-literal booleans in table key declarations (#816).
+  * Type variables from function results also resolve arguments (#838).
+  * Do not mistake missing optional argument for a vararg.
+* Improved code generation
+  * Generate `__is`-aware code for `is` on unions (#742).
