Palm has now released a new firmware for the Sprint branded Palm Pre and is WebOS version 1.0.4 according to an article over on engadget mobile.

Apparently the only change with WebOS 1.0.4 is to security issues and Palm even gives credit to Pre homebrewer, Townsend Ladd Harris for his cooperation in locating the security vulnerabilities.

Unfortunately Palm has now plugged the hole which allowed homebrew applications on the Palm Pre without any jailbreak, as the hole was dangerous to leave open, although apparently any software already installed will continue to work.
