pyparsing v2.0.1 Release Notes
Release Date: 2013-07-01 // almost 11 years ago-
✂ Removed use of "nonlocal" that prevented using this version of pyparsing with Python 2.6 and 2.7. This will make it easier to install for packages that depend on pyparsing, under Python versions 2.6 and later. Those using older versions of Python will have to manually install pyparsing 1.5.7.
🛠 Fixed implementation of <<= operator to return self; reported by Luc J. Bourhis, with patch fix by Mathias Mamsch - thanks, Luc and Mathias!
