-This will install the latest stable version which is ``1.0.0``. This
-version works well for the basic use case but has some limitations.
-
-An improved version ``2.0.0b1`` has been released as well. But as it's
-a beta version, pip will not find it by default. To install the latest
-beta version specify the ``--pre`` flag.

-The current stable version is tested with ``2.7``, ``3.4``, ``3.5``

-The ``v2beta`` branch has been tested with Python ``3.4``, ``3.5``, ``3.6``, ``3.7``,

+pipdeptree has been tested with Python versions ``2.7``, ``3.4``,
+``3.5``, ``3.6``, ``3.7``, ``3.8``, ``3.9-dev`` as well as ``pypy2``
+and ``pypy3``.
 
 Python ``2.6`` is way past it's end of life but if you ever find
 yourself stuck on a legacy environment, version ``0.9.0`` *might*
 work.
 
 
+Running in virtualenvs
+----------------------
+
+`New in ver. 2.0.0`
+
+If you want to run pipdeptree in the context of a particular
+virtualenv, you can specify the ``--python`` option. Note that this
+capability has been recently added in version ``2.0.0``.
+
+Alternately, you may also install pipdeptree inside the virtualenv and
+then run it from there.

-2. Due to (1), the output also includes ``pipdeptree`` itself as a

    understand that it's a bad idea but it mostly works! On rare
    occasions, it breaks when a new version of ``pip`` is out with
    backward incompatible changes in internal API. So beware if you are
