 # Unreleased
 
+- Switched simd base64 crate for one that works on stable (from `vb64` to `base64_simd`)
+- Allow boolean arguments to function as flags, without a `true` or `false` argument following the flag itself
+- Fix cropping issues when zooming out too much while using kitty protocol
+
+# v0.4.3
+
+- Fix issue with some terminals hanging on startup
+- Fix issues with some iterm2-backend terminals not displaying anything
 - Allow using ctrl+scroll to zoom in/out while zoomed using kitty backend
+- (Internal) run CI with `--locked` flag to ensure lockfile is always in-sync

 ## To Build
 First, you need to install the system dependencies. This will generally only include `libfontconfig` and `clang`. If you're on linux, these will probably show up in your package manager as something like `libfontconfig1-devel` or `libfontconfig-dev` and just `clang`.
