 * **Fix(stm32h5):** Prevent a HardFault crash on STM32H5 devices by changing `uid()` to return `[u8; 12]` by value instead of a reference. (Fixes #2696)
 ## Unreleased - ReleaseDate
 
+- feat: stm32/hrtim add new_chx_with_config to provide pin configuration
 - fix flash erase on L4 & L5
 - fix: Fixed STM32H5 builds requiring time feature
 - feat: Derive Clone, Copy for QSPI Config
