 ### 1.5.0 (20001)
-- Ported the entire scripting layer from Python 2 to to Python 3 (currently 3.5 to 3.7 depending on platform). There's some significant changes going from python 2 to 3 (new print statement, string behavior, etc), but these are well documented online, so please read up as needed.  This should provide us some nice benefits and future-proofs everything. (my janky 2.7 custom Python builds were getting a little long in the tooth)
+- Ported the entire scripting layer from Python 2 to to Python 3 (currently 3.5 to 3.7 depending on platform). There's some significant changes going from python 2 to 3 (new print statement, string behavior, etc), but these are well documented online, so please read up as needed.  This should provide us some nice benefits and future-proofs everything. (my janky 2.7 custom Python builds were getting a little long in the tooth)..
 - Refactored all script code to be PEP8 compliant (python coding standards).  Basically, this means that stuff that was camel-case (fooBar) is now a single word or underscores (foobar / foo_bar).  There are a few minor exceptions such as existing resource and media filenames, but in general old code can be ported by taking a pass through and killing the camel-case.  I know this is a bit of a pain in the ass, but it'll let us use things like pylint and just be more consistent with the rest of the Python world.
 - On a related note, I'm now using 'yapf' to keep my Python code formatted nicely (using pep8 style); I'd recommend checking it out if you're doing a lot of scripting as its a great time-saver.
 - On another related note, I'm trying to confirm to Google's recommendations for Python code (search 'Google Python Style Guide'). There are some good bits of wisdom in there so I recommend at least skimming through it.
