Hi,

the stable version of FeynCalc normally receives bug fixes until
a new stable version is released. The bug fixes go into the hotfix-stable
branch

https://github.com/FeynCalc/feyncalc/tree/hotfix-stable

which is used whenever one installs (or reinstalls) FeynCalc using the
automatic installer. The bug you are referring to was fixed in January
2017:

<https://github.com/FeynCalc/feyncalc/commit/365e480f9c6ad9820469c754bf1ae379f7300279>

You can just reinstall FeynCalc to have all the current fixes. And
better check out the hotfix-stable branch from time to time to be sure
that you are up to date.

Cheers,
Vladyslav
