+# DeepMind Lab Release Notes
+
+## Current Release
+
+### New Features:
+
+1. Lua customizable themes.
+2. String observations.
+3. Add ability for script to generate events visible to the EnvCApi.
+4. Updated EnvCApi to propagate error messages.
+5. Added customization point to enable reading files from external sources.
+
+### Minor Improvements:
+
+1.  Fixed ramp jump velocity in level lt_space_bounce_hard.
+2.  Fixed Lua function 'addScore' from module 'dmlab.system.game' to allow
+    negative scores added to a player.
+3.  Minor removal of undefined behaviour in the engine.
+4.  Change LuaSnippetEmitter methods to use table call conventions.
+5.  Added config variable for monochromatic lightmaps ('r_monolightmaps').
+    Enabled by default.
+6.  Python module 'observation_spec' now returns current observation spec.
+7.  Added config variable to limit texture size ('r_textureMaxSize').
+8.  Increased score range to include all 32 bit integers.
+9.  api:modifyTexture must now return whether the texture was modified.
+10. Internal engine events are propagated to the script via gameEvent.
+11. Added ability to adjust rewards.
+12. Added ability to raycast between different points on the map.
+13. Reduced inaccuracies related to angle conversion and normalization.
+14. Added flag "sv_rateLimit" to disable rate limiting for networked games.
