Also better handling by custom addon managers like wowup or ajour.

Essentially make use of the multitoc all wow client flavors support now Basic Rules

If the SlientRotate package contains these 2 files.

• SilentRotate-Classic.toc
• SilentRotate-BCC.toc

they can have the appropriate ## Interface: xxxxxx and the Classic-Era or BCC wow client will automatically load the correct one.
You can also have the traditional SilentRotate.toc file included which works as a fallback option if the wow client can't find a flavor specific .toc to load.

Fixed in the following commit: a9086b4

Will be available in the next release, which will be version 0.8.0.

Thank you for your support!

@Road-block It works like a charm in the game client, but when publishing to CurseForge, they have tools that check the archive and they require the basic SilentRotate.toc file…

Yeah, curseforge packager is slow on the uptake of new standards.
What I'd do is use the highest supported version as the fallback .toc in addition to the client specific files.

WoW client will load the client specific file anyway.
