Nov 13, 2025

API Manager

  • Fixed an issue where Twilio channels could not be updated if the credentials were not being changed as part of the update.

  • Fixed an issue where key-value pairs were mistakenly removed from directory member extensions and rules when passed via the SDK.

  • Fixed another issue where key-value pairs were removed from directory member contact tags when passed via the SDK.

Channel Manager

  • Added support to allow users to select a session_end_tool to be invoked at the end of a session when properly configured in a prompt.

Conversation Manager

  • Improved SMS conversations by sending back a farewell response (instead of nothing) if the user sends a farewell message.

Console

  • Released the new Highlights feature to showcase what’s new at Syllable.

Tools

  • Enabled Prompts to set any tool to be run at the end of the session, which was previously limited to be only the session_end tool.

  • Updated prompt editor toolbar to add additional buttons and tooltips:

    • Added support to display tooltips in the prompt editor and label the function of each button.

    • Made the prompt editor more user-friendly when inserting a link into the prompt by immediately accepting the link upon pressing “Enter”--eliminating the need to click the "Apply" button.

  • Removed the restriction that Workflows Description had to be Title Case.

  • Enhanced tool definitions to include support for DELETE and PUT HTTP methods–expanding the previously available GET and POST options.

  • Outbounds - Fixed an issue with sorting by ensuring Agents and Campaigns are ordered alphabetically by the first label.
