Version 1.3.0 was released March 7 (thanks!), but the version string in the master branch (in mpmath/__init__.py) is still 1.3.0. Could __version__ be updated to something like 1.4.0.dev0? Or something fancier that includes the git SHA in the version? I don't have a preference for which convention to use, but anything that distinguishes a master branch installation from a released version would be helpful.
