See what’s new and improved in our latest update.

### Modernized Workflow Builder Canvas UI

* Rebuilt canvas engine delivering 60fps hardware-accelerated panning, smooth zooming, and crisp node rendering on 4K displays.
* Smart wire routing automatically bends connector lines around intermediate nodes to eliminate visual clutter and spaghetti diagrams.
* Instant port snapping and magnetic connector guidance make wiring complex logic branches faster and more intuitive.

### Built-in Media Format Converters & Subtitle Generators

* Transform text transcriptions directly into timestamped subtitle files with the **TXT to SRT** converter node.
* Audio format conversion nodes support **MP3 to AAC** (and vice versa) for downstream podcast and speech processing pipelines.
* Automated SRT creator node integrates seamlessly with Video Generation and Speech-to-Text nodes for zero-touch video subtitle automation.

### Enhanced VectorDB Group Chat & Frontier Models

* Group multiple vector knowledge bases into conversational collections, allowing AI agents to synthesize insights across disparate PDFs, spreadsheets, and manuals.
* Full compatibility with cutting-edge frontier models including **GPT-5** and **Gemini 3 Pro** for superior multi-document retrieval and deep reasoning.
* Retains conversational thread memory and contextual source references during group chats.

<summary>Improved</summary>

* **Canvas Smart Layout:** Enhanced node placement logic to prevent newly added nodes from overlapping existing canvas structures.
* **Batch Flow Management:** Select multiple workflows using checkboxes to archive or categorize them in bulk from the dashboard.
* **Tag Editing UX:** Quick in-line tag renaming and color palette adjustments without opening flow settings modals.
* **Vector Group Context:** Optimized vector ranking algorithms to prioritize the most semantically relevant documents across large collections.

<summary>Fixed</summary>

* **Frontier Model Chat Timeout:** Resolved an API handshake bug where querying VectorDB using GPT-5 or Gemini 3 Pro caused intermittent timeout failures.
* **Multi-Source JSON Structure:** Fixed an issue where the Multi-Source JSON node corrupted array indexes when merging diverse JSON objects.
* **Node Multi-Select Drag:** Fixed an editor glitch where dragging a group of selected nodes caused lagging coordinates and dropped connections.
