 ### Added
 - Added `Path2DControlPoint.new` to the Roblox standard library
 - [Adds `lua_versions` to standard library definitions](https://kampfkarren.github.io/selene/usage/std.html#lua_versions). Specifying this will only allow the syntax used by those languages. The default standard libraries now specify these, meaning that invalid syntax for that language will no longer be supported.
+- Added missing third parameter to `PathWaypoint.new` in the Roblox standard library
 
 ### Changed
 - Upgrades to [full-moon 1.0.0](https://github.com/Kampfkarren/full-moon/blob/main/CHANGELOG.md#100---2024-10-08), which should provide faster parse speeds, support for multiple parsing errors at the same time, and support for some new Luau syntax.
