This patch-level release adds an EXTI API along with fixing a bug where the multitasker was spending too much time with interrupts disabled, which was impacting interrupt-dependent programs (such as an LMT01 temperature sensor driver) and fixing a bug where time was being reported as progressing as half its actual rate on the STM32F407. Additionally, an LMT01 temperature sensor driver along with an implementation of Conway's Game of Life using sixels are included.
