does the 50 civ dll for the 019 patch work with the new 021 patch?

The 50-civ DLL for 0.19 does not have any of the fixes of the last 2 versions, but I can compile a 50-civ version of 0.21

And a 50-civ version is now available for 0.21: http://forums.civfanatics.com/downloads.php?do=file&id=11120
