Restricting pylint version to 1.3 to ensure that prospector still can…

… handle Python 2.6 in the 0.7 releases. Python 2.6 support will be removed (and therefore pylint 1.4+ will be added) in the 0.8 releases

 ## Version 0.7.3
 
+* Pylint dependency version restricted to 1.3, as 1.4 drops support for Python 2.6. Prospector will drop support for Python 2.6 in a 0.8 release.
 * File names ending in 'tests.py' will now be ignored if prospector is set to ignore tests (previously, the regular expression only ignored files ending in 'test.py')
 * [#70](https://github.com/landscapeio/prospector/issues/70) Profiles starting with a `.yml` extension can now be autoloaded
 * [#62](https://github.com/landscapeio/prospector/issues/62) For human readable output, the summary of messages will now be printed at the end rather than at the start, so the summary will be what users see when running prospector (without piping into `less` etc)
