 ## Changed
 
 - Swapped PL and PS I2C, BPX battery and MGT are connected to PS I2C now for firmware versions
-  above v4. However, this software version ins compatible to both v3 and v4 of the firmware.
+  equal or above v4. However, this software version is compatible to both v3 and v4 of the firmware.
 - The firmware version variables are global statics inititalized early during the program
   runtime now. This makes it possible to check the firmware version earlier.
 
+## Fixed
+
+- TMP1075: Set dataset invalid on shutdown explicitely
+- Small fixes for TMP1075 FDIR: Use strange and missed reply counters.
