+===============================================================
+
+This release includes the following changes since 3.0.0:
+
+* Add functions to support Short Authentication String key verification.  The
+  new functions are in the ``sas.h`` header file.  The Android, iOS, JavaScript
+  and Python bindings also include corresponding functions.
+* Add functions to perform public key signing.  These are meant for use with
+  cross-signing.  The new functions are ``olm_pk_signing_size``,
+  ``olm_pk_signing``, ``olm_pk_signing_last_error``, ``olm_clear_pk_signing``,
+  ``olm_pk_signing_key_from_seed``, ``olm_pk_signing_seed_length``,
+  ``olm_pk_signing_public_key_length``, ``olm_pk_signature_length``, and
+  ``olm_pk_sign``.  Signatures generated by ``olm_pk_sign`` can be verified
+  using ``olm_ed25519_verify``.  The Android, iOS, JavaScript and Python
+  bindings also include corresponding functions.
+
+JavaScript wrapper:
+
+* Improved compatibility with newer versions of Emscripten, and dropped support
+  for some older versions of Emscripten.
+
+Python wrapper:
+
+* Build fixes.
+* Add bindings for the public key encryption/decryption functions from olm 2.3.0.
