+* qbsp: add "-maxNodeSize" option, from txqbsp-xt. Defaults to 1024. Makes large
+        maps process much faster and should generate better bsp trees.
+        If it causes a problem disable with "-maxNodeSize 0"
 * qbsp: make "mixed face contents" and "degenerate edge" non-fatal, from txqbsp-xt
 * qbsp: make "-oldaxis" the default. new "-nooldaxis" flag to get the previous behaviour.
 * light: add "-surflight_subdivide" flag to control amount of surface lights created
 * light, vis: use below normal process priority on Windows
 * light: allow negative surface light offset
-* light: ensure light values in the bsp equal the average of the lit file color components. 
-  This fixes "dark" colors (where all components are < 1), on some engines 
-  (such as MarkV), which require the bsp lightmap brightness to match the .lit brightness
-  as a cheat prevention mechanism.
+* light: average the lit file color components to generate the bsp lightmap value.
+         TODO: use a perceptually weighted average.
 * light: fix lighting of hipnotic rotating entities.
 * light: fix crash in "Bad texture axes on face:"
+* light: fix surface lights being mistakenly duplicated
+* light: add "-onlyents"
+* light: add "-dirtangle" setting to control dirtmapping cone angle, default 88 degrees.

+Switch to the cheap spatial subdivion bsp heuristic when splitting nodes
