Patch 2.2.0 (05 January 2018) Lots of battle optimizations:

don't call unnecessary updates on enemies

don't call unnecessary updates on effects

cache results of effect palette swaps rather than doing it EVERY SINGLE TIME

Fix occassional NaN values for a projectile's angle, which would trigger a while loop of SIX MILLION ITERATIONS (every update!!!!)

Throttle how many times an enemy's HP bar can be redrawn per unit of time (so it's not wastefully spammed when playing at e.g. x16 speed)

Cache results of scaled tiled bitmaps to reduce drawing time

Increase capacity of QuadTree nodes

Added surgical speed throttling -- if there's too many enemies on screen, x16 and x8 speed modes are disabled until you kill enough off. You'll only ever really encounter this limit on the endless bonus battles, and it should effectively increases framerate by not overtaxing the game.

Replaced "hot" text fields in battle with bitmap text fields, which update faster and cause less lag

Avoid playing multiple identical sound effects in rapid succession

Preload enemies to avoid stutter on the first spawn of each wave

Patch 1.1.50 (13 October 2015)

Adds professional Spanish Translation

Fixes visual bug with achievements:

Previously, when you got any of the "hero mode" achievements, recruiting a generic character afterwards would make the achievement appear unearned in the in-game interface. It was still marked as complete in data, but it seemed like it was no longer achieved in the menu visuals. This is now fixed; at the very least it should not happen anymore in the future, and it might even retroactively fix the issue for certain players.
