Version 40 notes:
25% speedup. Details:
Boolean dice rolls are no longer simulated; they have been tableized. You can see the table in the Data\StatTable.txt. What does this mean? To check all "yes-or-no" rolls like att vs def, MR vs penetration, morale vs morale penalty, I no longer roll 4 open-ended d6's, but generate a single random number and consult the table to see if it succeded. This gives virtually identical results and is much faster.
Bug in v39 fixed (all units were listed as having elemental magic).
Random magic is calculated at runtime. So if you simulate combat using units with random magic or random elemental picks, they will do slightly better, as they will sometimes get fire (+att), earth (+tprot), and air (+mirror images for units with glamour). All 8 randoms are simulated, but only those 3 affect the simulator combat.
Neverheals is now supported. Before, it did nothing; now, neverheals units will not regain HP when fighting in "Gauntlet" mode. This is not very noticable with low-HP undead hordes, but it is for large neverhealing constructs and undead jotuns.
