• New Gemini Models Added support for:
  • Gemini-3.1-flash-lite
  • Gemini-3-flash-preview.

​

Observability & Webhooks

• Outcome Generation: Outcomes now use the agent’s configured OpenAI model and include enhanced agent context, extracted call variables, and caller context for higher-quality, more consistent analysis.
• Failure Webhooks: NO_ANSWER and FAILEDwebhook payloads now include conversationId.
• Per-Node Logging: Conversation logs now include nodeId for better debugging and traceability across multi-node flows.
• LLM Metadata in Call History: Call history now records the LLM provider and model used for each call.

​

Platform Improvements & Fixes

• Scoped API Keys: API keys now support scoping with origin allowlists and scope assignment alongside root permissions. Expired keys are surfaced with an “expired” badge when listed.
• New JSON Editor: The JSON editor has been replaced with a new version that auto-fixes common errors

​

Media

• Voice AI creations feature: Generate complete voice overs from a natural-language description of what you need.
  • Provide a prompt, choose a dialect, and select the voice over type
  • Optionally enable background music generation
  • Each request returns three voice over suggestions
  • Suggestions are paired with matching voices and emotionally aligned background tracks when enabled
  • Generation runs asynchronously with Pending → Ready → Failed status tracking
  • Approve the preferred result once generation is complete
  • Failed generations are surfaced for easy retrying
• New Voices added: Additional voices have been added to the library, expanding the options available for both voice over and TTS.

​

Call Infrastructure & Performance

• Concurrent Calls Stability: Resolved outbound call concurrency issues, eliminating stuck PENDINGcalls and incorrect concurrency limits.
• Accurate Concurrency Enforcement: Concurrency limits are now enforced correctly across all call types.
• Unified Concurrency Pool: Campaign calls and direct API calls now share a single concurrency pool for consistent behavior.
• Improved Slot Handling: Failed or unanswered calls now correctly release concurrency slots, preventing bottlenecks.
• Inbound Concurrency Enforcement: Inbound calls now reserve slots in the user’s call queue, ensuring limits are applied consistently.
• Inbound Credit Validation: Inbound calls now validate account balance before connecting, preventing calls when credits are insufficient.

​

Call Data & Exporting

• Call Export Fix: Resolved issues related to exporting call data, ensuring accurate and reliable downloads.
• Optimized Data Exporting: Improved export performance by reducing memory usage, enabling reliable handling of large datasets without system instability.
• Scalable Data Processing: Enhanced backend processing to support high-volume data operations efficiently and prevent application crashes.
• Sentiment Analysis Optimization: Improved sentiment distribution processing to reduce memory consumption and produce faster, more reliable analytics.

​

Analytics & Reporting

• Dashboard Analytics Export: Export functionality is now available from the Dashboard page across the Overview, Performance, and Satisfaction tabs.
• Structured Excel Report: Exports produce a formatted Excel (.xlsx) file with three sheets: Overview, Performance, and Satisfaction.
• Report Metadata: Each sheet includes a “Hamsa Analytics Report” header with the selected agent name/ID and export timestamp.
• Dynamic Filtering Support: Exports respect active filters and date ranges, with filenames reflecting the selected period.

​

Canvas & Flow Builder

• Inline Node Renaming: Nodes can now be renamed directly from the canvas with inline editing.
• Quick Node Picker: Dropping an edge onto an empty area opens a modal to create and connect a node in one step.
• Auto Layout : Automatically arranges nodes horizontally or vertically to keep flows clean and readable, with no overlap.
• Canvas Follow Toggle: The canvas auto-pans to the active node during live calls, with a toggle to disable (saved per browser).
• Copy & Paste Nodes: Nodes can now be copied and pasted directly within the canvas.

​

APIs & Backend

• Single Jobs API Fix: Addressed bugs to improve stability and ensure consistent execution.

​

Projects & Team Collaboration

• Projects : Organize work into dedicated projects, each with its own agents, phone numbers, knowledge bases, and call history. Easily switch between projects from the top navigation.
• Team Invitations : Invite teammates via email through a streamlined signup flow. Expired invitations can be resent directly from the Members page.
• Roles & Permissions
• Assign roles
  • (Owner, Admin, User) and manage access with granular, per-resource permissions. Revert to role defaults at any time.
• Project Deactivation
  • Owners can deactivate projects to prevent further changes. Deactivated projects are hidden from non-owners and can be reactivated at any time.
• Unsaved Changes Protection
  • When switching projects with unsaved changes, you’ll now be prompted to confirm, reducing the risk of accidental data loss.

​

Call Settings

• Extended Call Duration
  • The maximum call duration has been increased from 30 minutes to 1 hour, and is now configured in minutes instead of seconds.
• Smart Call End Prompt
  • Customize the prompt used by the Smart Call End feature to better detect natural conversation endings.

​

Tools

• On-Hold Music
  • Tools can now play on-hold music while a tool call is executing.
• Collection Filtering
  • Filter the tools list by collection for faster navigation and improved organization.
• Tool Testing Improvements
