2.5 Sitemap Generator & vBulletin 4

I cant seem to find an answer to this and I apologize in advance if it has been already posted.

vBulletin is recommending that any hacks or mods to 3.8.x be removed before installing vBulletin 4.

Do I need to remove the sitemap generator or will it work with the new version 4?
I read in another thread here that vBSEO 3.3.2 can be left installed when installing vB4 and should cause no problems. I was hoping to hear the same thing about the 2.5 sitemap generator.

Thanks...

Neither vbseo 3.3.2 nor sitemap 2.5 will be compatible with vb4.

We are planning to launch vbseo 3.5 as close as possible to vb4 launch (we are shooting for same day, but can't guarantee that until it actually happens due to having little control over what vB does). with it, Sitemap 2.6 (tentative version number) will follow. Both these new versions will be compatible with vb4.
