Safari 4.0 beta 1 (second update)
Readers will recall that Safari 4.0 beta 1 failed to function with betas of Mac OS X 10.5.7 while it was under development. Therefore Apple has quietly updated its Safari 4.0 public beta with a new version supporting -- as well as requiring -- Mac OS X 10.5.7.

The new beta also addresses 3 security issues with the Safari 4.0 beta 1, including vulnerabilities with the browser's URL input validation, a heap buffer overflow problem with libxml, and a memory corruption issue in WebKit's handling
of SVGList objects.

Safari 3.2.3
Separately, Apple on Tuesday also released Safari 3.2.3, which addresses security issues with the web browser. The update is available as a 40MB download for Mac OS X 10.5.x Leopard, a 26.29MB download for Mac OS X 10.4.x Tiger, and a 19.69 download for Windows XP and Vista.

Tiger Security Updates
For users running Mac OS X 10.4.X Tiger, Apple also released Security Update 2009-002. It's available as a 165MB download for Intel Macs, a 75MB download for PowerPC Macs, and a 203MB download for all Mac OS X Tiger servers.

New updates are also showing up today for Safari Public beta and Safari 3.2.3, as well as a separate security update 2009-002.

After 10.5.6 broke my aluminium iMac (freezes related to Firewire drivers and an external HDD even when it was powered off), I think I'll wait a week or two and see if any problems are reported.

Good to see the update arrive though, I guess they're aiming to really finish off the last of the remaining Leopard issues with this release.

Is it compatible with Safari 4?
