 ## 1.12.1 - TBD
 
+* Ensure `DateTimeField` values are set to `UTC` timezones as FILETIME values are in UTC
+* Stop using `datetime.datetime.utcfromtimestamp()` as it has been deprecated
+
 ## 1.12.0 - 2023-11-09
 
 * Added the `DiskFull` error and message for the NTSTATUS code `0xC000007F` - https://github.com/jborean93/smbprotocol/pull/245
