Broken: version: 3.5.1 Release Candidate, branch: blender-v3.5-release, commit date: 2023-04-06 02:25, hash: 1bd46a46d15a

Short description of error
The issue causes the Glossy Direct pass to produce different results than it did in previous versions of Blender, which breaks compatibility with existing workflows and renders.

This bug makes the Glossy Direct pass unusable for compositing ( Which i rely on daily ) and post-processing purposes.

I hope this issue can be fixed soon. Thank you very much for your attention and your great work on Blender.

Exact steps for others to reproduce the error
Open attached file and render. Check glossy pass.

This was an intentional change, the previous behavior was inconsistent with other closures and pass types (e.g. diffuse). The entire point of the direct/indirect vs. color split in the passes is the the direct/indirect passes should be independent of the material color. See e.g. #104041.

You can get the old result by enabling the Glossy Color pass and multiplying Glossy Direct with Glossy Color in the compositor.

Looks like I forgot to add this to the release notes, I'll update them now.

Thanks for clarification, I also could have read commit message more in detail. Will close since this is intended change.
