Windows 10 Technical Preview support has been added, let me know how it goes for you on the forum, and which new components you would like to see added first.
Bare in mind, this is Technical Preview support, I cannot guarantee final version support before it is out.
Language pack integration was upgraded to do the boot.wim part automatically and also to select Setup language in Automation.
Language component removals are now included in the free version, due to the fact that Win10 now also has them in CPanel-Features.
For more details check the changelog.
Next on my list would be translation support for the tool itself, but I’ll update with fixes in parallel before if something comes up.
