Summary

When generating the Sparkle appcast, generate_appcast logs warnings that it cannot find the Sparkle.framework version for prior
releases, and falls back to default delta generation. This happens because Sparkle.framework is embedded under Contents/PlugIns
instead of the standard Contents/Frameworks path.

Observed warnings (example):

• Warning: Sparkle.framework version for xxxx.app (1.1.1 (111)) was not found. Falling back to generating delta using default delta version.

Possible Fix

generate_appcast to provide a parameter to specify the Sparkle.framework path.

Version

2.8.1
