+### [const-tweaker]
+
+![const-tweaker UI](./const-tweaker.gif)
+
+Thomas Versteeg has released a new crate called `const-tweaker`, which provides
+a web UI that can be used to tweak `const` variables in a running application.
+This can be used as a simpler alternative to embedded scripting languages or
+hot-reloading in your games.

+
+### [assets_manager]
+
+a1phyr has created a crate called `assets_manager`, which provides a convienient way
+to load and cache external resources. It abstracts over the filesystem logic, and
+provides a variety of built-in loaders for common Serde formats (e.g. TOML, JSON).
+Hot-reloading support is also planned in the future.
