Changelog for python2-BitVector-3.4.9-lp152.2.3.noarch.rpm :

* Mon Apr 01 2019 Tomáš Chvátal - Update to 3.4.9:
* Version 3.4.9, in addition to implementing __iadd__, also includes a significantly faster implementation for __add__. For extending a given instance of BitVector, the implementation for __iadd__ adds bits to the existing instance as opposed to creating a new instance. These changes to the module should make it easier to solve larger problems more quickly with BitVector.
