+- Relative mouse events and infinite mouse movement (allowing for FPS-style
+  control schemes)
+- Extra methods for getting and setting the state of a playing sound
+
+For full details and a list of breaking changes, see the [changelog][tetra-changelog].
+
+Additionally, this month [puppetmaster] released [tetrapack], a set of useful
+extensions for Tetra. This includes:
+
+- Helpful timer types
+- Looping background music
+- Custom mouse cursors
