+- Update to v 4.0.0
+  * Removed deprecated modules:
+    + rsa.varblock
+    + rsa.bigfile
+    + rsa._version133
+    + rsa._version200
+  * Removed CLI commands that use the VARBLOCK/bigfile format.
+  * Ensured that PublicKey.save_pkcs1() and PrivateKey.save_pkcs1() always return bytes.
+  * Dropped support for Python 2.6 and 3.3.
+  * Dropped support for Psyco.
+  * Miller-Rabin iterations determined by bitsize of key.
+  * Added function `rsa.find_signature_hash()` to return the name of the
+    hashing algorithm used to sign a message. `rsa.verify()` now also
+    returns that name, instead of always returning `True`.
+  * Add support for SHA-224 for PKCS1 signatures.
+  * Transitioned from `requirements.txt` to Pipenv for package management.
