+## [0.3.1] (29 November 2024)
+
+This patch version mostly includes a set of library API extensions made to fit the
+needs of developing MEV-resistant blockchain node. Also, this release bumps minimum
+required Go version up to 1.22 and contains a set of bug fixes critical for the
+library functioning.
+
+Minor user-side code adjustments are required to adapt new ProcessBlock callback
+signature, whereas the rest of APIs stay compatible with the old implementation.
+This version also includes a simplification of PrivateKey interface which may be
+adopted by removing extra wrappers around PrivateKey implementation on the user code
+side.
+
 Behaviour changes:
  * adjust behaviour of ProcessPreBlock callback (#129)
  * (*DBFT).Header() and (*DBFT).PreHeader() are moved to (*Context) receiver (#133)
