Alright, all you bleeding-edge upgraders out there - get those broadband pipes opened up and get over to PHP.net and download the much anticipated release of PHP 4.3.0!
Here's just a few of the improvements:
Improvements and fixes on the Command line interface, and makes it more separate for use outside of the PHP module for web servers.
Streams support is now fully functional: What this means for users is that any I/O function that works with streams (and that is almost all of them) can access built-in protocols, such as HTTP/HTTPS and FTP/FTPS, as well as custom protocols registered from PHP scripts.
A new build system with one master makefile, instead of a bunch of smaller ones.
As well as some smaller changes, like the inclusion of GD in the actual PHP installation (no more external libraries), lots of deprecated extenstions were removed, and others were enhanced with additional features and more stable code. For the full list, see the changelog.
So, what are you waiting for? Get over there and download it now!
