+1.3.4 (Feb 22, 2024):
+- Add FIPS-compliant build for amd64/linux
+
 1.2.0 (Jan 25, 2024):
 - Added support for Flag Sets on the SDK, which enables grouping feature flags and interacting with the group rather than individually (more details in our documentation):
   - Added new variations of the get treatment methods to support evaluating flags in given flag set/s.
