 # [unreleased]
 
+# [v1.27.0] 2023-02-13
+
+Added EIVE system top mode component. Currently, only SAFE and IDLE mode are
+implemented, and the system does not do more than commanding TCS and ACS
+into the correct modes. It does not have a lot of mode tracking capabilities
+yet because the ACS controller might alternate between SAFE and DETUMBLE.
+It takes around 5-10 seconds for the EIVE system to reach the SAFE mode.
+
+The new system is used at software boot to command the satellite into safe mode
+on each reboot. This behaviour can be disabled with the
+`OBSW_SWITCH_TO_NORMAL_MODE_AFTER_STARTUP` flag.
+
+## Added
+
+- New EIVE system component like explained above.
+
+## Changed
+
+- The satellite now commands itself into SAFE mode on each reboot, which
+  triggers a lot of events on each SW reboot. The TCS subsystem will commanded
+  to NORMAL mode immediately while the ACS subsystem will be commanded to
+  SAFE mode. The payload subsystem will be commanded OFF.
+- `RELEASE_BUILD` flag moved to `commonConfig.h`
+- The ACS subsystem transitions are now staggered: The SUS board assembly
+  is commanded as a separate transition. This reduces the risk of long bus lockups.
+- No INFO mode event translations for release builds to reduce number of
+  printouts.
+- More granular locking inside the MAX31865 low level read handler.
+
+## Fixed
+
+- More DHB thermal module fixes.
+- ACS PST frequency extended to 0.8 seconds in debug builds to avoid SPI
+  bus lockups.
+- Local datapool fixes for the `PlocSupervisorHandler`
+
