+# Python-RSA changelog
+
+
+## Version 4.1 - in development
+
+- Dropped support for Python 2 and 3.4.
+- Added type annotations to the source code. This will make Python-RSA easier to use in
+  your IDE, and allows better type checking.
+- Added static type checking via [MyPy](http://mypy-lang.org/).
+- Fix [#129](https://github.com/sybrenstuvel/python-rsa/issues/129) Installing from source
+  gives UnicodeDecodeError.
+- Switched to using [Poetry](https://poetry.eustace.io/) for package
+  management.
+- Added support for SHA3 hashing: SHA3-256, SHA3-384, SHA3-512. This
+  is natively supported by Python 3.6+ and supported via a third-party
+  library on Python 3.5.
+
+
+## Version 4.0 - released 2018-09-16
+
+- 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.
+  [#58](https://github.com/sybrenstuvel/python-rsa/pull/58)
+- 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`.
+  [#78](https://github.com/sybrenstuvel/python-rsa/issues/13)
+- Add support for SHA-224 for PKCS1 signatures.
+  [#104](https://github.com/sybrenstuvel/python-rsa/pull/104)
+- Transitioned from `requirements.txt` to Pipenv for package management.
+
+
+## Version 3.4.2 - released 2016-03-29
+
+- Fixed dates in CHANGELOG.txt
+
+
+## Version 3.4.1 - released 2016-03-26
+
+- Included tests/private.pem in MANIFEST.in
+- Included README.md and CHANGELOG.txt in MANIFEST.in
+
+
+## Version 3.4 - released 2016-03-17
+
+- Moved development to GitHub: https://github.com/sybrenstuvel/python-rsa
+- Solved side-channel vulnerability by implementing blinding, fixes #19
+- Deprecated the VARBLOCK format and rsa.bigfile module due to security issues, see
+    https://github.com/sybrenstuvel/python-rsa/issues/13
+- Integration with Travis-CI [1], Coveralls [2] and Code Climate [3]
+- Deprecated the old rsa._version133 and rsa._version200 submodules, they will be
+  completely removed in version 4.0.
+- Add an 'exponent' argument to key.newkeys()
+- Switched from Solovay-Strassen to Miller-Rabin primality testing, to
+  comply with NIST FIPS 186-4 [4] as probabilistic primality test
+  (Appendix C, subsection C.3):
+- Fixed bugs #12, #14, #27, #30, #49

+
+
+## Version 3.3 - released 2016-01-13
+
+- Thanks to Filippo Valsorda: Fix BB'06 attack in verify() by
+  switching from parsing to comparison. See [1] for more information.
+- Simplified Tox configuration and dropped Python 3.2 support. The
+  coverage package uses a u'' prefix, which was reintroduced in 3.3
+  for ease of porting.

+
+
+## Version 3.2.3 - released 2015-11-05
+
+- Added character encoding markers for Python 2.x
+
+
+## Version 3.2.1 - released 2015-11-05
+
+- Added per-file licenses
+- Added support for wheel packages
+- Made example code more consistent and up to date with Python 3.4
+
+
+## Version 3.2 - released 2015-07-29
+
+- Mentioned support for Python 3 in setup.py
+
+
+## Version 3.1.4 - released 2014-02-22
+
+- Fixed some bugs
+
+
+## Version 3.1.3 - released 2014-02-02
+
+- Dropped support for Python 2.5
+
+
+## Version 3.1.2 - released 2013-09-15
+
+- Added Python 3.3 to the test environment.
+- Removed dependency on Distribute
+- Added support for loading public keys from OpenSSL
+
+
+## Version 3.1.1 - released 2012-06-18
+
+- Fixed doctests for Python 2.7
+- Removed obsolete unittest so all tests run fine on Python 3.2
+
+## Version 3.1 - released 2012-06-17
+
+- Big, big credits to Yesudeep Mangalapilly for all the changes listed
+  below!
+- Added ability to generate keys on multiple cores simultaneously.
+- Massive speedup
+- Partial Python 3.2 compatibility (core functionality works, but
+  saving or loading keys doesn't, for that the pyasn1 package needs to
+  be ported to Python 3 first)
+- Lots of bug fixes
+
+
+
+## Version 3.0.1 - released 2011-08-07
+
+- Removed unused import of abc module
+
+
+## Version 3.0 - released 2011-08-05
+
+- Changed the meaning of the keysize to mean the size of ``n`` rather than
+  the size of both ``p`` and ``q``. This is the common interpretation of
+  RSA keysize. To get the old behaviour, double the keysize when generating a
+  new key.
+- Added a lot of doctests
+- Added random-padded encryption and decryption using PKCS#1 version 1.5
+- Added hash-based signatures and verification using PKCS#1v1.5
+- Modeling private and public key as real objects rather than dicts.
+- Support for saving and loading keys as PEM and DER files.
+- Ability to extract a public key from a private key (PEM+DER)
+
+
+## Version 2.0
+
+- Security improvements by Barry Mead.
