[Mediawiki-l] PHP 5.1.6

[Tolliver]

Hello,

I have upgraded to MediaWiki 1.16.0 on my test wiki's. However, we 
currently run PHP 5.1.6 (upgrading within a month). Would you suggest 
waiting until PHP has been upgraded, or is there folks running a non 
supported version without issue.

What would the recommendation be? I am interested to know what the 
potential for issues would be.

Current:
MediaWiki Ver. 1.11.0


Thank you!
