IsoBuster 5.0 Beta Released!

March 3, 2022

Normally we release a Beta version only a few weeks before its final release. IsoBuster 5.0 final is planned for the middle of June, 2022. This time we take a different approach because of the huge changes under the hood.

IsoBuster 5.0 is far from ready, but we need as much feedback as possible, as soon as possible, and the software will certainly benefit from a longer public test cycle.

The massive changes guarantee that IsoBuster will still be relevant in the distant future.

From now on there will be two versions that can be used under the same license. A 32 bit version and a 64 bit version. Any modern system these days is 64 bit and that's the IsoBuster version you should be using as well. For legacy reasons however we will still maintain a 32 bit version as well, for as long as that is possible.

The 32 bit version supports Windows XP and higher (Windows XP, Vista, 7, 8, 10 and 11)

The 64 bit version supports Windows Vista and higher (Windows Vista, 7, 8, 10 and 11)

Contrary to normal Beta release notes, which don't change anymore, these release notes are not final and will still change. This is still very much a version in development, and while it certainly works very stable already, things will still change and more functionality will still be added.

So, you can already use this version if you want, we'd certainly like that, because then we benefit from the feedback
