 # [unreleased]
 
+## Added
+
+- Added `EXECUTE_SHELL_CMD` action command for `CoreController` to execute arbitrary Linux commands.
+
 ## Fixed
 
 - Pointing control of the `AcsController` was still expecting submodes instead of modes.
 - Limitation of RW speeds was done before converting them to the correct unit scale.
+- The Syrlinks task now has a proper name instead of `MAIN_SPI`.
