New Features
Developer Tools Overhaul

All dev tools now share a common panel with drag, resize, pop-out to a separate window, and fullscreen. Panel state persists when switching between tools.

DataTracker (new)
Pick any block and instantly see all its properties updating in real time. Makes it much easier to understand how a creative is configured and spot issues.

JSON Viewer & Provider (rewritten)
Now with syntax highlighting, tree view, and search. The provider validates JSON before loading it into the builder, so you know something is wrong before it breaks.

Analytics Monitor (new)
Makes it easier to see what's happening under the hood. Shows clicks, flow steps, visibility, and milestones as they happen in the creative. Powered by the new analytics bridge in Engine 6.8.6.

Bug Fixes
VAST Tag Export

Bulk tag export is now outputting a URL instead of a tag. The copy button label also adapts to whether you're copying tags, URLs, or a mix. In single creative delivery, the redundant “Copy to clipboard” button is hidden when VAST is active.

Analytics Pages for Large Brands

Brands with many campaigns could cause analytics and report pages to not load at all. The campaign list request was hitting URL length limits in the browser. Now uses a different request method that handles any number of campaigns.

Mass-Format Creative Renaming

Renaming a mass-format creative from the creative list was silently failing. The update wasn't being sent in the format the API expects for mass-format creatives. Now correctly renames both the parent and all child creatives.
