Every change the AI agent makes in Roblox Studio is recorded per session, with a change summary, timeline, and Before & After comparison.
Overview
The Changelog tracks the game change history that AI agents perform in Studio. Changes are grouped by session so you can see at a glance what type of changes happened and how many in each session.

Session Status
Each session card displays a status:
| Status | Meaning |
