First off, I am new to this list, and asking questions about m0n0wall. I 
did a search of the archives and couldn't come up with anything.

Why was the beta switched back to 4.x? Was it stability or security 
reasons? Is there any reason to NOT use the 5.3 beta releases at this 
time? The reason I am asking is that I wanted to use a 802.11b/g card.  
Will a b/g card function under 4.x but only in b mode?

I have read the beta changelog, but are there any critical 
vulnerabilities since the revert back from FreeBSD 5.3? Thanks.
