PHP 4.3.0 is out!
PHP 4.3.0 was recently released after a long testing phase. The bit I'm most excited about is the built-in gd image processing library with support for EXIF data (shutter speeds etc) from digital camera photos. Compiling the gd library seems to be quite a difficult task (my own web host seems to have stuffed it up in recent times) so this should make it easier to install.
That said, I'm having trouble on the ATNF server as I get png related errors when I attempt to compile 4.3.0. I suspect it's having trouble with zlib support, which seems strange as I am passing PHP the same zlib directory information as for previous versions.
