 # [unreleased]

+# [v6.0.0] to be released
+
+- Important bugfixes for PTME. See `q7s-package` CHANGELOG.
+
+# [v5.2.0] 2023-07-02
+
+## Fixed
+
+- The firmware information event was not triggered even when possible because of an ordering
+  bug in the initializer function.
+- Empty dumps (no TM in time range) will now correctly be completed immediately
+
+## Changed
+
+- PTME was always reset on submode changes. The reset will now only be performed if the actual data
+  rate changes.
+- Add back ACS board code for the EM. Now that the radiation sensor was removed, the image switching
+  issue has disappeared and adding back the ACS board is worth it for the GPS timekeeping.
+
+# [v5.1.0] 2023-06-28
+
+- `eive-tmtc` version v5.1.0
+
+## Changed
+
+- Persistent TM store dumps are now performed in chronological order.
+- Increase Syrlinks RX HK rate to 5.0 seconds during a pass.
+- Various robustness improvements for the heater handler. The heater handler will now only
+  process the command queue if it is not busy with switch commanding which reduces the amount
+  of possible bugs.
+- The heater handler is only able to process messages stricly sequentially now but is scheduled
+  twice in a 0.5 second slot so something like a consecutive heater ON or OFF command can still
+  be handled relatively quickly.
+
+## Added
+
+- Sequence counters for PUS and CFDP packets are now stored persistently across graceful reboots.
+- The PUS packet message type counter will now be incremented properly for each PUS service.
+- Internal error reporter set is now enabled by default and generated every 120 seconds.
+
+# [v5.0.0] 2023-06-26
+
+v3.3.1 and all following version will now be moved to v5.0.0 with the additional changes listed
+here. This was done because the firmware update (v4.0.0) is not working right now and it is not
+known when and how it will be fixed. Because of that, all updates to make the SW work with the new
+firmware, which are limited to a few files will be moved to a dev branch so regular development
+compatible to the old firmware can continue.
+
+TLDR: This version is compatible to the old firmware and some changes which only work with the new
+firmware have been reverted.
+
+## Changed
+
+- Added `sync` syscall in graceful shutdown handler
+- Graceful shutdown is now performed by the reboot watchdog
+- There is now a separate file for the total reboot counter. The reboot watchdog has its own local
+  counters to determine whether a reboot is necessary.
+
+# [v4.0.1] 2023-06-24
+
+## Fixed
+
+- `PusLiveDemux` packet demultiplexing bugfix where the demultiplexing did not work when there was
+  only one destination available.
+
 # [v4.0.0] 2023-06-22

 - `eive-tmtc` version v5.0.0
@ -45,6 +110,17 @@ will consitute of a breaking change warranting a new major release:
  restore the PL I2C.
 - Core controller now announces firmware version as well when requesting a version info event

+# [v3.3.1] 2023-06-22
+
+## Fixed
+
+- `PusLiveDemux` packet demultiplexing bugfix where the demultiplexing did not work when there was
+  only one destination available.
+
+## Fixed
+
+- Fixed H parameter in SUS converter from 1 mm to 2.5 mm.
+
 # [v3.3.0] 2023-06-21

 Like v3.2.0 but without the custom FM changes related to VC0.
