Update information about Python 3

docs/python3.rst

@@ -7,53 +7,25 @@ Flask and all of its dependencies support Python 3 so you can in theory
 start working on it already.  There are however a few things you should be
 aware of before you start using Python 3 for your next project.
 
-Requirements
-------------
-
 If you want to use Flask with Python 3 you will need to use Python 3.3 or
 higher.  3.2 and older are *not* supported.
 
 In addition to that you need to use the latest and greatest versions of
-`itsdangerous`, `Jinja2` and `Werkzeug`.
-
-API Stability
--------------
+`itsdangerous`, `Jinja2` and `Werkzeug`. Flask 0.10 and Werkzeug 0.9 were
+the first versions to introduce Python 3 support.
 
 Some of the decisions made in regards to unicode and byte utilization on
 Python 3 make it hard to write low level code.  This mainly affects WSGI
 middlewares and interacting with the WSGI provided information.  Werkzeug
 wraps all that information in high-level helpers but some of those were
 specifically added for the Python 3 support and are quite new.
 
-A lot of the documentation out there on using WSGI leaves out those
-details as it was written before WSGI was updated to Python 3.  While the
-API for Werkzeug and Flask on Python 2.x should not change much we cannot
-guarantee that this won't happen on Python 3.
-
-Few Users
----------
-
-Although moving to Python 3 should be done someday, most people still use
-Python 2 for now.  As a result many of the problems you will encounter are
-probably hard to search for on the internet if they are Python 3 specific.
-
-Small Ecosystem
----------------
-
-Some Flask extensions, documentation and PyPI provided libraries do not
-support Python 3 yet.
-
-Even if you start your project with knowing that all you will need is
-supported by Python 3 you don't know what happens six months from now.
-But if you are familiar with Python 3 and Flask extension, you can start
-porting libraries on your own.
-
-Recommendations
----------------
-
-Unless you are already familiar with the differences in the versions we
-recommend sticking to current versions of Python until the ecosystem
-caught up.
+Unless you require absolute compatibility, you should be fine with Python 3
+nowadays. Most libraries and Flask extensions have been ported by now and
+using Flask with Python 3 is generally a smooth ride. However, keep in mind
+that most libraries (including Werkzeug and Flask) might not quite as stable
+on Python 3 yet. You might therefore sometimes run into bugs that are
+usually encoding-related.
 
 The majority of the upgrade pain is in the lower-level libararies like
 Flask and Werkzeug and not in the actual high-level application code.  For
