Version History and Rollback for Individual Experiences

[#1]

Description:
In Adobe Target, once changes are made to an experience (e.g., offer content, audience rules, design tweaks in VEC), there is no built-in versioning or rollback functionality for that specific experience. If a mistake is introduced or someone wants to revert to a previously working version, it often requires manually redoing the changes or referencing screenshots or documentation - if available.

Why is this feature important to you:
Teams working on multiple activities across A/B tests and personalization campaigns need the ability to iterate quickly and safely. Mistakes can happen, especially in large organizations or distributed teams. Having a version history would reduce risk, support better collaboration, and speed up debugging and approval workflows. It’s especially useful for regulated industries or agencies where approval trails matter.

How would you like the feature to work:
Each experience within an activity should automatically store a version history whenever a change is made. This should include:

• A timestamp

• The name of the user who made the change

• A summary of what was changed (e.g., audience modified, HTML updated, design edited)

Users should be able to:

• View previous versions

• Compare them visually or via a diff view

• Restore a previous version with a single click

Optional: Allow notes/tags for major changes ("v1 approved", "client review", etc.).

Current Behaviour:
Currently, Adobe Target does not offer any version history or rollback capability. Once a change is saved and/or published, the previous version is lost unless manually backed up or documented outside the system.
