# Changelog Export — Turn History into Proof

Changelog Export turns project history into a clear, shareable record you can trust. Pick a date range and generate a PDF that shows who changed what and when across tasks, constraints, and zones.

### Why This Matters

Construction programmes shift daily; without a dependable trail, small edits become costly surprises. A verified changelog strengthens contract positions, accelerates dispute resolution, and keeps everyone aligned to the latest plan. It replaces opinion with evidence, building confidence from site to boardroom.

### What’s New?

Export a time-boxed change report as a consistent, ready-to-share PDF. Choose the timeframe and the content, including tasks, constraints, and zone changes. Schedule delivery so the right people receive regular updates by email.

### How It Helps

Planners and coordinators review weekly edits to protect schedule health and catch control gaps early. \
**Highlights:** audit-ready evidence, claims support, schedule health monitoring, team alignment, automated oversight.

### Example use cases

 After leave, a Project Manager downloads last week’s log to review schedule edits before escalating issues. Also, during a variation claim, a team attaches the report to evidence impact and timing.
