Release Notes

What's new in Guava.

June 16, 2026

Guava 0.30.0 adds a new chat widget supporting audio and text, inbound SMS support, in-CLI management of outbound campaigns, Do Not Call list checks for outbound campaigns, and an updated intent recognizer.

New Features

  • A new multimodal widget (guava-widget-audio-chat) supports audio and text chat within a single session.
  • Agents can now send DTMF digits during a call using call.set_agent_dtmf(enabled=True).
  • on_session_end handlers now receive a termination_reason field describing why the session ended, available in both the Python and TypeScript SDKs.
  • GET /v1/conversations now accepts phone-number query parameters to filter results by caller or callee.
  • Reach-person detection has been updated to v2 with improved accuracy.
  • Agents can read incoming messages via a new inbox API endpoint and the next_sms (Python) / nextSms (TypeScript) SDK methods.
  • Agent.chat mode in the TypeScript SDK enables text-based (non-voice) conversation sessions.
  • MockCall and per-handler unit test support have been added to the TypeScript SDK, allowing agent handlers to be tested in isolation.
  • SDK agents now attach to an existing campaign via campaign_code. Create campaigns through the API or dashboard before starting an agent.
  • Do Not Call (DNC) list support has been added to campaigns; numbers on the list are automatically skipped when dialing.
  • Contacts API v2 adds expanded filtering and batch management capabilities.
  • A new IntentRecognizer class in guava.helpers.llm uses Guava's LLM endpoint for intent recognition.
  • OpenAI-compatible wrappers have been added for document QA and vector store workflows. VertexAI helpers have been renamed to GenAI helpers (guava.helpers.genai).
  • New CLI subcommands: guava contact upload, guava conversations, and guava campaigns.
  • guava login now accepts a --no-launch-browser flag for headless and CI environments.
  • CLI configuration is now stored as a plain TOML file, making it easy to inspect and edit by hand.
  • guava deploy now includes a dashboard view showing the status of active deployments.
  • Campaigns can now be created and edited directly from the dashboard.

Improvements

  • Updated guava create project templates. See the CLI Reference.
  • Outbound dialing and SMS compliance forms have been updated with bug fixes and improved field syncing.
  • A skipDeprecationCheck option has been added to the TypeScript SDK client constructor.

June 9, 2026

Guava 0.29.0 introduces text-based chat sessions, an agent testing framework, CLI self-upgrade, and TypeScript SDK Transport v2.

New Features

  • Agents can now conduct text-based chat sessions in addition to voice calls.
  • An initial agent testing framework has been added to the Python SDK, including guava.testing.MockCall for mocking call interactions.
  • The guava CLI now supports self-upgrade via guava self-upgrade, updating the binary in place. See the CLI Reference.
  • The TypeScript SDK has been updated to Transport v2, with a rewritten socket layer, updated event types, and improved inbound call handling.
  • The TypeScript SDK now supports CLI-based authentication, removing the need to pass API keys explicitly when the guava CLI is in use.
  • The LLM helper (guava.helpers.llm) in the Python SDK now authenticates via CLI credentials.
  • Added outbound scheduling examples to the Python SDK with --local flag support.

Improvements

  • Phone numbers are now displayed and formatted correctly during guava create flows.
  • Improved error handling when agent code throws exceptions during execution.
  • Improved call screener resilience against transient errors in both the Python and TypeScript SDKs.

Bug Fixes

  • Fixed guava deploy up incorrectly defaulting to an inbound deployment when run on an existing project without a .guava configuration file.

June 2, 2026

Guava 0.28.0 brings smarter intent handling, automated SMS follow-up for unanswered campaign calls, and CLI improvements.

New Features

  • Agents now handle ambiguous user intents more robustly. A new intent helper method returns a list of plausible matches, and the on_action_request callback accepts this list to naturally disambiguate with the caller.
  • Agentic campaigns now automatically send an SMS follow-up when a call goes unanswered, informing the recipient of the attempt to reach out.
  • guava run now accepts additional arguments to pass through to the running agent. See the CLI Reference.
  • The TypeScript SDK now supports local calling.

Improvements

  • The WebRTC Helper has been updated to v0.2.0, fixing slow bot audio and Bluetooth headset connection issues.
  • The API and Python SDK now warn when attempting to stop a campaign that has already dispatched calls.

Bug Fixes

  • Fixed a crash triggered by multiple action requests or questions said at once.
  • Fixed a bug where admin users were unable to delete deployments from the dashboard.
  • Fixed an issue where inbound calls could be routed incorrectly.

May 27, 2026

WebRTC support arrives in the TypeScript SDK, agentic tenacity comes to campaigns with SMS, and CLI messaging is refined.

New Features

  • The TypeScript SDK now includes WebRTC support, with an updated property-insurance example to get started.
  • Python SDK examples now open an interactive phone number picker when run in an interactive terminal session.
  • The guava deploy command now provides clearer, more informative output messages.
  • Agentic tenacity is now available for campaigns with SMS enabled.

Bug Fixes & Improvements

  • Updated the quickstart guide with separate install method sections and added agent test and stop steps.
  • The docs section now has its own dedicated navigation bar.
  • Various website fixes and content updates.

May 19, 2026

Guava introduces new and improved tools for measuring outbound calling campaign performance.

New Features

  • A new Campaign Stats Endpoint enables querying of call outcome statistics, with support for filtering by multiple statuses. See the Campaign reference for details.
  • A PowerShell install script has been added for Windows CLI installation.

Bug Fixes & Improvements

  • Voicemail detection accuracy is improved. "Voicemail" as a call termination reason is now reported by agents and tracked in autodialer campaigns, yielding better campaign outcomes data. See set_voicemail_action() for related configuration.
  • The process for approving outbound calling and SMS agent workflows has been streamlined. Read more about requesting outbound permissions here.
  • Various refinements to ASR (speech recognition), TTS (text-to-speech), and background noise handling.

May 12, 2026

The Guava CLI makes gains in utility and flexibility. TTS pronunciation is improved.

New Features

  • guava create and guava update now support non-interactive mode, making it easier for scripts, CI pipelines, and agents to run commands. See the CLI Reference.
  • Added guava numbers list to list phone numbers from the CLI.
  • Added guava run to run your agent project locally. See the CLI Reference.
  • The Guava CLI is now available as a Windows binary. See the CLI Reference.
  • Added get_var / set_var as shorter aliases for get_variable / set_variable in the Guava Agent API.
  • call_info is now accessible directly on the call object.
  • The Python SDK can now authenticate using CLI credentials.

Bug Fixes & Improvements

  • For spelling back words (e.g. "I have that as 'Guava, spelled G-U-A-V-A'"), TTS pronunciation and rate of speech are improved.

May 5, 2026

The Guava Agent API gains voice configuration, DTMF event support, and call ID access. Campaigns now support custom caller IDs for pre-approved accounts.

New Features

  • Added a voice parameter to the Agent class.
  • Exposed call.id for use in agent code.
  • Added support for DTMF events in the Guava Agent API.
  • Pre-approved accounts can set their own number as the caller ID for outbound calls. See the Campaign reference.
