For those updating from a46 to a47 be sure to check the contents of the directories, I found these (new) files in a47:

\bbsdir\data\bademail.txt
\themes\default\scripts\autocreate.mp*
\themes\default\scripts\tetris.mp*
\themes\default\scripts\testpy3.mpy
\themes\default\scripts\startup.*

The following old scripts gave compile errors in my a46 AND a47 setup: bulletin.mps and filelist.mps After copying the new ones they worked again.

And I found that when using the NF menu command (new files) without a parameter crashes your, ehm I mean my board.

Maybe there is more ....

Have phun!

... That's not a bug, it's an undocumented feature
