+eive-tmtc: v2.14.0
+
+Event IDs for PDEC handler have changed in a breaking manner.
+
+## Added and Fixed
+
+- PDEC: Added basic FDIR to limit the number of allowed TC interrupts and to allow complete task
+  lockups in the case an IRQ is immediately re-raised by the PDEC module. This is done by only
+  allowing a certain number of handled IRQs (whether they yield a valid TC or not) during
+  time windows of one second. Right now, 800 IRQs/TCs are allowed per time window.
+  This time window is reset if a TC reception timeout after 500ms occurs. TBD whether the maximum
+  allowed number will be a configurable parameter. If the number of occured IRQs is exceeded,
+  an event is triggered and the task is delayed for 400 ms.

 - Patch version which compiles for EM
 - CFDP Funnel bugfix: CCSDS wrapping was buggy and works properly now.
+- PDEC: Some adaptions to prevent task lockups on invalid FAR states.

 - CMakeLists.txt fix which broke CI/CD builds when server could not retrieve full git SHA.
 - Possible regression in the MAX31865 polling task: Using a `ManualCsLockGuard` for reconfiguring
   and then polling the sensor is problematic, invalid sensor values will be read.
