www.lighttpd.net/2007/7/24/1-4-16-let-s-ship-it

It contains fixes for crashing bugs discovered by over the last weeks and we encourage to upgrade from earlier releases to 1.4.16. Especially lighttpd-SA2007-03 should convince you to upgrade. It can crash all lighttpd 1.4.x releases. In 1.5.0 this is fixed as we replace the parser by a generated one and replacing the hand-crafted one in 1.4.×.
