mzCalc v1.2.1 updates the parser to deal with the new race headers on the stats page, and makes the race column optional. You should once again be able to paste the entire stats page into a text file.
Note that mzCalc does not replicate the Thief/Clipper bug. That's a deviation from the bcalc, but an unavoidable one, because I have no way of determining which ship actually gets to fire first. Therefore, instead, it lets both ship types to fire half their guns. It has worked this way since the first release.
Just a small update.
