 # [unreleased]
 
+# [v1.44.1] 2023-04-12
+
+- eive-tmtc: v2.22.1
+
+## Fixed
+
+- Bugfixes and improvements for SDC state machine. Internal state was not updated correctly due
+  to a regression, so commanding the SDC state machine externally lead to confusing results.
+- Fixed a bug in persistent TM store, where the active file was not reset of SD card switches.
+  SD card switch from 0 to 1 and vice-versa works without errors from persistent TM stores now.
+- Add a way for the SUS polling to detect broken or off devices by checking the retrieved
+  temperature for the all-ones value (0x0fff).
+- Better reply result handling for the ACS board devices.
+- ADIS1650X initial timeout handling now performed in device handler.
+- The RW assembly and TCS board assembly now perform proper power switch handling for their
+  recovery handling.
+
+## Changed
+
+- Added additional logic for SDC state machine so that the SD cards are marked unusable when
+  the active SD card is switched or there is a transition from hot redundant to cold redundant mode.
+  This gives other tasks some time to register the SD cards being unusable, and therefore provides
+  a way for them to perform any re-initialization tasks necessary after SD card switches.
+- The TCS controller pauses operations related to the TCS board assembly (reading sensors and 
+  the primary control loop) while a TCS board recovery is on-going.
+
+## Changed
+
+- Allow specifying custom OBSW update filename. This allowed keeping a cleaner file structure
+  where each update has a name including the version
+- The files extracted during an update process are deleted after the update was performed to keep
+  the update directory cleaner.
