Q3 2026 (Jul-Aug)

Enhancements

  • Node IDs Now Visible in Node Configuration
    Each node's unique ID is now displayed directly within its configuration panel in Data Flow, making it faster to reference specific nodes when troubleshooting or communicating with support.

  • Direct Link from Hound Jobs to Filtered Reports
    Hound job results now include a direct link to the Data Flow Reports page, pre-filtered to show only the sessions relevant to that job, removing the need to manually search or filter afterward.

  • Audio Player Added to the Reports Page
    An in-page audio player has been added to the Data Flow Reports page, letting users listen to call recordings directly from the report view without downloading them first.

  • Static Masking for Permanent Data Redaction
    Building on Dynamic Masking, tenants can now enable Static Masking to permanently redact sensitive personal data at the database level via a background process, giving customers with strict compliance requirements a way to irreversibly remove personal information rather than only hiding it on-screen.

  • Templates Available When Adding a Custom Node
    The "Add New Custom Node" dialog now offers ready-made templates, making it faster to get started when building a new custom node instead of beginning from a blank editor.

  • Updated AI Usage Disclaimer
    The AI usage disclaimer shown in Core Web has been updated to reflect SESTEK Core branding, along with refreshed legal text and links, ensuring the disclaimer accurately reflects the current product and terms.

  • Filler-Word-Aware Barge-In Detection
    Data Flow can now ignore filler words when detecting barge-in, reducing false barge-in triggers caused by callers making brief sounds rather than genuinely interrupting.

  • Template Support for Hound Bulk Processing
    Hound's Bulk Processor now supports templates, making it easier to configure and reuse common bulk-processing setups.

  • Stereo Audio and Channel Switch on the Test Page
    The Data Flow test page now supports stereo audio with a toggle to switch between channels, making it easier to test and review two-channel call scenarios directly from the test screen.

Improvements

  • Turkish Character Support Extended to Custom Node String Values
    Following the recent fix for Turkish character input in the custom node editor, string-type parameter values within custom nodes now also correctly support Turkish characters, closing a remaining gap in localized text entry.

  • Redesigned Voice and Language Selector
    The voice and language selector dropdown in Core Web has been redesigned for clearer navigation and easier selection when configuring TTS voices.

  • Readable Language Names in the Voices Table
    The Voices table now displays language codes as readable, human-friendly names instead of raw codes, making it easier to identify the language of each voice at a glance.
