 ## 0.2.4 – unreleased
 
+- **New mod "Mountain 3 crash fix"** (Gameplay): the rolling boulder spawners in Mountain chapter 3
+  deleted themselves too early and their boulders later wrote into the freed memory (use after free),
+  which can crash the game in `FreeLocalMem`. One word of level data keeps the spawners alive.
 - **New mod "Developer mode"** (Cheats): turns on the game's hidden developer switch. Hold A+S to
   warp to the developers' warp points, F1 to fly, F2 for a heart and 5 fruit, F3/F11 to count idols
   and coins up; Space on the river log makes it invincible and fast.
