 # Dependencies
-* Python 2/3  
-> For now the extension is Python2/3 compatible.  
-> However since now [Python2 has reached the EOL](https://www.python.org/doc/sunset-python-2/), all the feature will be tested on Python3 from now on.  
-> I'll try my best to keep this extension as a Python2/3 compatible project, however there's still a possibility that I might drop the support of Python2 in the future.
+* Python 3  
+
+> I decided to drop the support of Python2.7 since it has [reached the EOL](https://www.python.org/doc/sunset-python-2/). I believe the project is Python2/3 compatible, however there might exist some issues in pykd and can cause different behavior in Python2/3. Since now the project will only be tested on Python3, I strongly suggest using TWindbg on Python3 instead of Python 2.7. If you still want to use it on Python 2.7, feel free to fork the project and do the development.
