March 2025: Stabilized the AMD gfx10 path in the tinygrad runtime by delivering a safety fix to the gfx10 control stack size calculation. The change bounds the stack size to not exceed 0x7000 and adds a minimum value constraint to prevent underflow, preventing potential runtime crashes on affected hardware. This work was implemented in commit b6fe5ab4dd11609ab8e8dd4cec9c6fa5cfe89bf7 (fix: correct gfx10 ctl stack size (#9384)). No new features shipped this month; the primary value delivered is increased runtime stability and reduced risk for customers on gfx10 hardware.
