Better start using Monticello for for managing your source, changesets
are actually hard to use. I use changesets in Squeak/Pharo only to
recover code changes after potential image crash.

I hope someone will answer that one.

Pharo actually use the same VM, yes, so Pharo is fork only on image
level. Squeak and Pharo images also not differ too much yet. From end
user standpoint mostly on look&feel.

Only if your really need a speed, ue Cog at that time, otherwiser
rather start with official VM. One click images are the best bet. Cog
namelly still has some issues, so waiting a bit more is advisable.

Source of all code is in changes file, while in image there are aonly
pointers to the last version of each class/method.
