The only changes to freeBoot, afaik, are to support different dashboard versions.
fbBuild is the project that replaced freeBOOT. I won't go into detail about the fbbuild.exe changes.
fbBuild v0.01 was the initial release, and they dubbed the kernel as "freeBOOT v0.04", and implemented msdash 12611, tweaked the freeBOOT exploit for both boot-speed and stability.
There was no "fbBuild v0.05".
fbBuild v0.030 was the first release dubbed as "freeBOOT v0.06", and implemented msdash 13146, and had various xell and freeBOOT bugfixes and patches.
fbBuild v0.031 had no significant changes beyond the fbBuild.exe, still used msdash 13146, and had NO freeBOOT kernel changes or fixes.
fbBuild v0.032 was the first release dubbed as "freeBOOT v0.07", and implemented msdash 13599, and had NO freeBOOT kernel changes or fixes.
fbBuild v0.033 was still dubbed as "freeBOOT v0.07", and implemented msdash 13604, with NO other changes aside from the kernel generation core (fbBuild.exe itself).
Ikari stopped his releases on v0.032, and below are the freeBOOT by Ikari changelogs:
v0.032 - 04-18-2010
Bug Fixes
=============
- fixed profile corruption
- fixed xb1 emu
- updated xellous
New Features
=================
- updated to kernel 2.0.9199
- now supports all consoles and flashing solutions (ikari)
- removed memory protections
Code can be executed and modified anywhere in the range from 0x80000000
to 0x9FFFFFFF. This can be used to create game trainers and will allow
for porting of emulators, which rely on dynamic compilation.
[2 different patches 1 with this: xbox1 emu doesn't, 1 without xbox1 emu does work]
- encrypted DevKit XEXes are now working
- includes dash launch patch
- LIVE/PIRS/GOD content fully working
- internal security breach reports deactivated (Redline99)
