+Subject: [PATCH] Further improve server tick loop
+
+Improves how the catchup buffer is handled, allowing it to roll both ways
+increasing the effeciency of the thread sleep so it only will sleep once.
+
+Also increases the buffer of the catchup to ensure server stays at 20 TPS unless extreme conditions
+
+Previous implementation did not calculate TPS correctly.
+Switch to a realistic rolling average and factor in std deviation as an extra reporting variable

+Subject: [PATCH] Optimize explosions
+
+The process of determining an entity's exposure from explosions can be
+expensive when there are hundreds or more entities in range.
+
+This patch adds a per-tick cache that is used for storing and retrieving
+an entity's exposure during an explosion.
