+
+[rg3d] is a game engine that aims to be easy to use and provide large set
+of out-of-box features. Some of the recent updates:
+
+- Implemented fully asynchronous resource loading.
+- Added compressed textures support (DXT1, DTX3, DTX5).
+- Added filtering and wrapping options for textures.
+- Added sky box.
+- Added texture import options for resource manager.
+- All dependencies were moved to rg3d workspace, so there is no need to
+  manually download them when working with the latest version of the engine.
+- Extracted HRTF code in the separate [crate][hrtf], so it could be used
+  without rg3d.
+- Lots of other bugfixes and improvements.
