[pstricks] pstricks main package updated? (\psaxes question included)

[Hubert Lam (Publishing)]

Ran the MiKTeX updater today and noticed the main pstricks package was 
updated (old: 22/1/2008) to 24/2/2008.

Just wondering what may have changed?

I notice in the 22/1 version of pstricks, when \psaxes[...] is drawn, 
the labels are no longer in math mode but in text mode, causing the 
"minus" signs to be dashes.
