Two minor improvements have been added:
You can now UNPRICE items (a bit more below), and
There is a new form of the TYPO command.

HELP SHOPKEEPING has been updated to reflect the new syntax:
UNPRICE [SINGLE|ALL] item
-or-
PRICE [SINGLE|ALL] item NOTFORSALE

The benefit of this new syntax is that if you do it first, then
remove the item from your stockroom, it will not 'remember' its
previous price if you try putting it for sale again later.
Well, that's one benefit!

The new form of the TYPO command is:
TYPOHERE your typo report

The idea is that if you see a typo in a particular place, go to
that place and enter TYPOHERE this room has misspelt 'course' as
'coarse'.
Then we will know where to look for your typo report!
