@ -16,6 +16,102 @@ will consitute of a breaking change warranting a new major release:

 # [unreleased]

+# [v6.5.1] 2023-09-12
+
+- Bumped `eive-tmtc` to v5.5.0.
+
+# [v6.5.0] 2023-09-12
+
+## Changed
+
+- Relaxed SUS FDIR. The devices have shown to be glitchy in orbit, but still seem to deliver
+  sensible raw values most of the time. Some further testing is necessary, but some changes in the
+  code should cause the SUS devices to remain healthy for now.
+- The primary and the secondary temperature sensors for the PLOC mission boards are exchanged.
+- ACS parameters for the SUSMGM (FLP) safe mode have been adjusted. This safe mode is now the
+  default one.
+- MGM3100 Startup Configuration: Ignore bit 1 of the CMM reply, which is sometimes set to
+  1 in the reply for some reason.
+
+# [v6.4.1] 2023-08-21
+
+## Fixed
+
+- `PDEC_CONFIG_CORRUPTED` event now actually contains the readback instead of the expected
+  config
+- Magnetic field vector was not calculated if only MGM4 was available, but still written to
+  the dataset. This would result in a NaN vector. Allowance for usage of MGM4 is now checked
+  before entering calculation.
+
+# [v6.4.0] 2023-08-16
+
+- `eive-tmtc`: v5.4.3
+
+## Fixed
+
+- The handling function of the GPS data is only called once per GPS read. This should remove
+  the fake fix-has-changed events.
+- Fix for PLOC SUPV HK set parsing.
+- The timestamp for the `POSSIBLE_FILE_CORRUPTION` event will be generated properly now.
+
+## Changed
+
+- PDEC FDIR rework: A full PDEC reboot will now only be performed after a regular PDEC reset has
+  failed 10 times. The mechanism will reset after no PDEC reset has happended for 2 minutes.
+  The PDEC reset will be performed when counting 4 dirty frame events 10 seconds after the count
+  was incremented initially.
+- GPS Fix has changed event is no longer triggered for the EM
+- MGM and SUS rates now will only be calculated, if 2 valid consecutive datapoints are available.
+  The stored value of the last timestep will now be reset, if no actual value is available.
+
+## Added
+
+- The PLOC SUPV HK set is requested and downlinked periodically if the SUPV is on now.
+- SGP4 Propagator is now used for propagating the position of EIVE. It will only work once
+  a TLE has been uploaded with the newly added action command for the ACS Controller. In
+  return the actual GPS data will be ignored once SPG4 is running. However, by setting the
+  according parameter, the ACS Controller can be directed to ignore the SGP4 solution.
+- Skyview dataset for more GPS TM has been added
+- `PDEC_CONFIG_CORRUPTED` event which is triggered when the PDEC configuration does not match the
+  expected configuration. P1 will contain the readback of the first word and P2 will contain the
+  readback of the second word.
+- The MGM and SUS vectors being too close together does not prevent the usage of the safe
+  mode controller anymore.
+- Parameter to disable usage of MGM4, which is part of the MTQ and therefore cannot be
+  disabled without disabling the MTQ itself.
+
+# [v6.3.0] 2023-08-03
+
+## Fixed
+
+- Small SCEX fix: The temperatur check option was not passed
+  on for commands with a user data size larger than 1.
+- SCEX: Properly check whether filesystem is usable for filesystem checks.
+- ACS Controller strategy is now actually written to the dataset for detumbling.
+- During detumble the fused rotation rate is now calculated.
+- Detumbling is now exited when its exit value is undercut and not its entry value.
+- Rotation rate of last cycle is now stored in all cases for the fused rotational rate
+  calculation.
+- Fused rotation rate estimation during eclipse can be disabled. This will also prevent
+  detumbling during eclipse, as no relevant rotational rate is available for now.
+- `EiveSystem`: Add a small delay between triggering an event for FDIR reboots and sending the
+  command to the core controller.
+- PL PDU: Fixed bounds checking logic. Bound checks will only be performed for modules which are
+  enabled.
+
+## Changed
+
+- SCEX: Only perform filesystem checks when not in OFF mode.
+- The `EiveSystem` now only sends reboot commands targetting the same image.
+- Added 200 ms delay between switching HPA/MPA/TX/X8 and DRO GPIO pin OFF.
+- PL PCDU ADC set is now automatically enabled for `NORMAL` mode transitions. It is automatically
+  disabled for `OFF` mode transitions.
+
+## Added
+
+- PL PCDU for EM build.
+- SCEX: Add warning event if filesystem is unusable.
+
