Just thought I'd share this knowledge:
The last forge for 1.3.2 is Forge 4.3.5.318 ( build 318 )
It does not have a star in the Jenkins page ( build 303 is the last recommended one for 1.3.2 ) but it is the final 1.3.2 build and between 303 and 318 there was one update where Richard G was mentioned ( hello Richard G )
The last forge for 1.4.2 is Forge 6.0.1.355 ( Build 355 )
Many mods recommend using Forge 353 but I've not yet encountered one that works on 353 but not on 355 and 355 also seems to fix that nasty error in server tick loop crash :
Description: Exception in server tick loop
java.util.ConcurrentModificationException
wich I used to get on 353
To get Forge go here:

This page is never down and has changelogs and everything.
Hope this helps you.
