A Question was asked on the wp-hackers mailing list:
Does a map of PHP versions to available functions exist? I can look up the
PHP function reference to see which version a function appeared in, but I’m
not aware of a reverse mapping (and I must be Googling very badly today).

Well.. I couldnt find one either, So i created a hacked-together list very quickly: http://dd32.id.au/php-functions-by-version.htm
It simply allows you to view what functions were added to a specific PHP version, This was prompted by WordPress moving to PHP 4.3+ for version 2.5 which is due out later this year.
Hopefully its of use to someone.
Sorry for the delay in the posting of this message, Its just something i’ve been continuously putting off.
Theres not much i can really report on the topic, So if you’ve got anything specific, feel free to leave a comment and i’ll see if i can dig up the information for you.
The Bureau of Meteorology was nice enough to send me over the river height details for Kyogle/Wiangaree from the 1st of Jan, to 11th of Jan 2008, So for those interested, I’ve put together a graph:

Some points used in the data on the above graph were interpolated from the data given to create a smooth line due to the data for river levels at certain times being missing(I guess they had more important things to do than measure the water level every few minutes :)). The raw CSV data is available upon request.
Current(and previous) News is indexed by Google pretty well: http://news.google.com/news?um=1&tab=wn&client=opera&hl=en&hs=Qnj&rls=en&q=Kyogle+flood&ie=UTF-8&scoring=n
AFAIK, The only (human)death that occured during the flood was near Mullumbimby. Source
