+This release drops support for Python 2, requiring at least
+version 3.5 of Python.
+
+changes
+^^^^^^^
+- Drop support for Python 2 and mark in setuptools as only supporting 3.5 and upwards
+- remove landscape.io badge
+- replace viivakoodi with python-barcode which is maintained
+- add configuration for Visual Studio Code
+- use pkg_resources for the retrieval of the capabilities.json
+
+contributors

 2020-05-09 - Version 3.0a7 - "No Fixed Abode"
 ---------------------------------------------
 This release is the eight alpha release of the new version 3.0.

CONTRIBUTING.rst

@@ -27,25 +27,6 @@ Style-Guide
 
 When writing code please try to stick to these rules.
 
-Python 2 and 3
-^^^^^^^^^^^^^^
-We have rewritten the code in order to maintain compatibility with both Python 2 and Python 3.
-In order to ensure that we do not miss any accidental degradation, please add these imports to the top
-of every file of code:
-
-.. code-block:: Python
-
-  from __future__ import absolute_import
-  from __future__ import division
-  from __future__ import print_function
-  from __future__ import unicode_literals
-
-Furthermore please be aware of the differences between Python 2 and 3. For
-example `this guide <https://docs.python.org/3/howto/pyporting.html>`_ is helpful.
-Special care has to be taken when dealing with strings and byte-strings. Please note
-that the :py:meth:`~escpos.escpos.Escpos._raw`-method only accepts byte-strings.
-Often you can achieve compatibility quite easily with a tool from the `six`-package.
-
 PEP8
 ^^^^
 The entire codebase adheres to the rules of PEP8.
