 ## Unreleased
+* MSRV (Minimum Supported Rust Version) is now `1.65.0` ([#2314](https://github.com/emilk/egui/pull/2314)).
 * ⚠️ BREAKING: egui now expects integrations to do all color blending in gamma space ([#2071](https://github.com/emilk/egui/pull/2071)).
 * ⚠️ BREAKING: if you have overlapping interactive widgets, only the top widget (last added) will be interactive ([#2244](https://github.com/emilk/egui/pull/2244)).
