+## [Version 2.0.2] — 2024-08-23
+
+* Use the `const` keyword instead of `define()` for slight performance gains, easier readability, and better IDE interoperability. Props @ChadSikorra and @ramsey for the recommendation! ([#23])
+

 * Now that constants are namespaced, remove the `defined()` checks and unnecessary multiplication in order to a) help IDEs and b) remove an (albeit tiny) level of overhead ([#21])
