It will be PHPNuke 4.5 compatable, the only changes to 4.4 was more fluff and more bugs... It's a wait right now, frankly PHPNuke is being ruined by the manner in which the addons are being included. I've started a new project called vBShell that will eventually replace Nuke2vB completely, it will have the same functionality but be more modular in respect to the addons. Everyone doesn't want or need all those addons that PHPNuke has and it's a major chore just to remove one or add another.
