Agent Platform Updates & Release Notes

Patch Release

Workflows

Set a default value for data entry fields in Workflows

Workflow builders can now set the default value of fields in a Data Entry node using either static text or expressions. Expressions can reference data from workflow triggers or previous workflow steps. For example, a reviewer’s form can be pre-filled with an AI-generated draft for approval or editing.

SDK

Control attachment visibility in the Web SDK

The Web SDK Theme Builder now has a toggle to show or hide the attachment icon in the chat widget’s compose bar. This lets FAQ and informational AI agents offer a cleaner, text-only interface when file uploads aren’t needed, while keeping attachments enabled by default elsewhere.

Analytics

Control SQL query operations for public analytics widgets

Admins can now allow or restrict specific query operations for public-facing analytics dashboard widgets, from a new SQL Validation section in the Public Widget Data Policy settings. Supported restrictions include SQL comments, multiple SELECT statements, JOIN clauses, common table expressions (CTEs), set operations (UNION, INTERSECT, EXCEPT), and OR conditions.

Major Release

Feature enhancements and new capabilities introduced in this release are summarized below, followed by the breaking changes that may affect existing projects — review the migration steps before recompiling or republishing them on 1.4.0.

Agent building (ABL/Studio)

Rich-content buttons can open a link on click

Message ACTIONS buttons and carousel card buttons can be configured with a URL so that clicking it opens the link directly in a new tab, instead of posting an action back to the agent. It is supported on the Web SDK/widget, Telegram, and LINE; other channels automatically fall back to a normal button.

Git integration for agent projects

Developers can connect a Git repository to a project to sync agent definitions and localization assets with version control, including push and pull from the Studio editor and conflict-resolution tools for simultaneous edits.

Inline ABL editor on the agent canvas

You can now edit agent logic directly in an inline code editor without leaving the visual canvas.

Voice

Configurable caller-silence (“no-input”) handling for pipeline voice agents

Voice agents on the KoreVG/Jambonz pipeline can now set re-prompt messages, retry counts, and timeout windows for silent callers, with locale-aware prompts and a final action (hang up, custom message, or transfer).

Custom vocabulary for speech-to-text

You can tune speech recognition to recognize domain-specific terms such as product names and jargon. It leads to improved accuracy in transcriptions.

Filler-agent context and language routing for IVR

Filler (“thinking”) audio during voice calls now carries conversation context and follows the caller’s active language.

No more silent gaps during backend tool calls

Updates to filler and no-input handling with Google Gemini Live now reduce dead air, repeated speech, and lost language context while a voice agent waits for a backend tool call. The updates require no configuration change.

Channels

Microsoft Teams: user-identity and channel-template support

Microsoft Teams connections can now resolve caller identity and add user details like email address, display name, or user ID to the context.

HTTP Async (webhook) channel: interruption and streaming support

The HTTP Async channel now supports mid-response interruption and streamed delivery of agent responses.

Multiple message rendering

Agents can now send several distinct messages in one turn, each rendered as a separate bubble instead of one combined block.

APIs and SDKs

Agent transfer uses webhook channel now. Agent transfer supports transfering attached documents. The allowed file formats and file size limits are defined in project-level attachment settings.

SDK sessions now receive a runtime-controlled activityVisibilityPolicy that decides updates of which customer-facing activity to show. It lets you control fillers like Searching..., safe thought summaries, action progress, system notices, and redacted tool previews. Raw reasoning, secrets, and unsafe tool data is hidden.

Analytics and Insights

Public API for saved dashboard-widget data

External tools, BI connectors, and scheduled exports can now fetch the data behind any saved custom-dashboard widget through a public REST endpoint, without re-implementing its underlying query. It supports both synchronous requests and asynchronous jobs with polling and cursor-based pagination.

PII entity preview

You can now preview which entities in a conversation will be detected and masked as PII before publishing an agent.

Integrations and Single Sign-on

Workspace sign-up, SSO, and access requests have new controls

Tenantless users are now routed to onboarding instead of being left in an ambiguous state, workspace SSO is separated from org SSO, and sign-up or workspace creation can be gated by feature flag. Review these settings after upgrading, especially if your org uses SSO or gated sign-up. Invited and password-recovery SSO users are now routed through separate flows, and Azure SSO app selection and Azure BYOK metadata are represented as structured fields instead of opaque JSON — review these if your workspace uses Azure SSO or BYOK.

Workflows

Workflow enhancements

Workflows now have better support for array-typed inputs/outputs, per-workflow rate limits, scheduled (cron) triggers, a JSON step editor, and an improved workflow overview page.

LLM and Model Configuration

Adaptive thinking config in Anthropic models

The platform now supports adaptive thinking as a configuration for Opus 4.7 and Opus 4.8 models.

Breaking changes and what to check before moving to 1.4.0

The changes below affect existing projects when you move to 1.4.0. Review the items relevant to your role developer or admin, and resolve them before promoting or republishing projects on the new version.

For agent developers

Supervisor role is now explicit

canRespondDirectly is deprecated as the primary way to set supervisor behavior. New agents should declare BEHAVIOR: role: router (route only) or role: orchestrator (combine results and respond). Existing agents keep working through compatibility mapping, but a role that conflicts with the old boolean setting now fails to compile.

Routers can no longer own returned work

A router can only select the next agent. If the parent needs to use a child agent’s returned result, declare it an orchestrator instead. Agents that use DELEGATE inside a router will no longer compile.

Compiler warnings can now block publishing

Diagnostics that used to be silently accepted — conflicting role and flag settings, routers containing DELEGATE, unmapped handoff inputs, unsupported tool array schemas — now stop a project from compiling or publishing. Review and resolve any outstanding warnings before promoting existing projects on 1.4.0.

Handoff and delegate inputs must resolve, or the call fails

A handoff or delegate no longer runs with a missing or stale input value. Add an explicit MEMORY read for any value the child needs, and use ON_RETURN to map back the results the parent depends on.

For deterministic FLOW parents, HANDOFF with RETURN: true now suspends at the transition boundary and resumes from the saved next step once the child returns — review verifier, auth, eligibility, and multi-agent flows where a parent depends on a child’s returned values.

Tools must declare the memory they read and write

A tool that needs conversation memory must declare context_access.read and/or context_access.write. If the declared memory isn’t available, the tool doesn’t run — check tools that previously assumed memory was always present.

Declare the item type for array inputs

Workflow array inputs still work without an item type, but declaring one — for example itemType: "string" — is now recommended. Workflow and connector array parameters are also projected into the model-facing tool schema with an items definition in 1.4.0, so some model providers (for example Gemini/Vertex) can reject the whole tool declaration if a typed array doesn’t declare its item type.

Review PII detection settings

New projects start with no built-in PII detection enabled by default (enabled_builtins: []). If your agent relied on default PII protection, explicitly enable the detection types you need before publishing.

Re-check SearchAI metadata and title filters

Filters that were previously dropped or ignored — unknown standard filters, metadata filters, and title-only filters — are now honored correctly. Review saved knowledge base and tool filters, since results may return different, more accurate documents after upgrading.

Gather validation outputs are now canonical

FLOW gather validation and retry-exhaustion fields are now lowered into the canonical execution model instead of relying on display-only alias names or implicit retry fallbacks. Make gather validation outputs explicit and don’t rely on a label as if it were a runtime variable name.

Terminal output is held until the final response is confirmed

Runtime now defers final output until response checkpoints pass, which cuts down on duplicate terminal responses and output arriving after cancellation — but it also surfaces incorrect output-ownership wiring earlier. Re-test multi-agent flows with async fan-out, remote handoff returns, delayed voice responses, or structured COMPLETE payloads without text.

Review agents that branch on channel or transfer state

Message metadata, channel identity, and transfer state now persist more consistently across reconnects, cancellation, escalation, and remote handoff returns. If an agent branches on channel identity or resumes after a remote or human-agent transfer, re-test it on 1.4.0.

Patch Release

This update includes a new feature summarized below.

Voice

Improved Microsoft streaming TTS reliability

Voice channels using Microsoft streaming text-to-speech now provide more reliable voice playback following periods of silence, reducing interruptions and helping ensure agent responses continue to stream as expected.

New voice provider: Sarvam AI

Sarvam AI is now available as a native speech-to-text and text-to-speech provider with tenant-scoped credential management.

Original source

Patch Release

This update includes features and enhancements summarized below.

Voice

Improved Microsoft Streaming TTS Reliability

Voice channels using Microsoft streaming TTS no longer risk a silent dead-air disconnect after a period of silence. A configurable keep-alive interval (5–25 seconds, default 15s) in Speech Synthesis settings proactively refreshes the TTS connection before the provider times it out, ensuring subsequent turns continue streaming audio normally.

New Voice Provider: Sarvam AI

Sarvam AI is now available as a native speech-to-text and text-to-speech provider with tenant-scoped credential management.

Major Release

This update includes features and enhancements summarized below.

Multi-agent and Arch AI

Real-time Arch AI activity feedback

The Arch AI activity panel now shows live, readable updates on each action as it happens, instead of delayed or raw output.

Arch loop evaluation and optimization

Arch AI now supports an iterative eval-optimize loop, allowing agents to be evaluated and refined through repeated automated passes, including voice-agent evaluation scenarios.

Arch AI engine tracing

Arch AI now produces structured trace events for each internal step of agent generation, optimization, and evaluation, giving visibility into Arch’s multi-step reasoning process for debugging and optimization.

Voice diagnostics knowledge for Arch AI

Arch AI can now offer diagnostic guidance for voice issues like missing audio, TTS failures, or STT misconfiguration.

Persistent memory: Append, unique, and max-size modifiers

Agent memory (REMEMBER STORE) can now append values to arrays, with optional deduplication and a size cap, rather than overwriting them. This makes it easier to build agents that accumulate history, like preferences or past interactions, over time.

Voice

Call recording

Voice agents now support call recording through the Kore Voice Gateway, with project-level recording configuration and enterprise recording policy enforcement. Recordings can be stored in Azure Blob Storage in addition to the platform’s default storage.

Outbound DTMF tones

Voice agents can now send outbound DTMF tones during a call, enabling interaction with IVR systems and other DTMF-driven telephony endpoints.

Genesys Cloud integrations

Artemis now integrates with Genesys Cloud on two fronts: the Audio Connector for live voice calls routed from Genesys Cloud, and Open Messaging for digital/text conversations routed through Genesys Cloud’s contact center.

Voice transcript sync and pre-transfer history on handoff

When a voice agent hands off a call to Kore SmartAssist/CCAI, the conversation transcript is synced to the receiving system, and a new API exposes the full pre-transfer conversation history, giving the receiving agent complete context.

Voice agent transfer via Kore Voice Gateway

Voice agents can now transfer live calls via SIP through the Kore.ai Voice Gateway, carrying conversation context to the transfer target.

Custom vocabulary and keyword boosting for speech-to-text

Voice channels now support custom vocabulary and keyword boosting for speech-to-text providers, improving recognition accuracy for domain-specific terms — configurable at the project level and per deployment channel.

Locale-aware agent responses

Reasoning agents can now reference project locale assets directly in their ABL responses, enabling multi-language agent output driven by the session locale without hardcoding translations.

Channel-appropriate response formatting

A single reasoning agent can now reliably produce channel-appropriate output—Markdown formatting for web and natural spoken text for voice—from one agent definition, without needing separate agents per channel.

Workflows and integrations

SOAP/WSDL integration support

Workflows and tools now support SOAP integrations: upload a WSDL file, browse its available operations, and register them as SOAP-type HTTP tools for agents and workflows — with a dedicated WSDL asset repository that supports versioning.

Integration actions as agent tools

Pre-built connector actions (for example, Jira or Slack operations) can now be added directly as agent tools — pick a connector and action from a catalog, and the platform handles authentication and parameter mapping automatically.

Webhook transport for contact-center handoff

Artemis now supports a webhook-based transport to hand off conversations to CCAI/SmartAssist and exchange ongoing customer messages during a live escalation.

Knowledge base and Search AI

New packaged connectors: Confluence, ServiceNow, SFTP, and Google Drive

The knowledge base connector catalog now includes packaged connectors for Confluence Cloud (with permission-aware delta sync), ServiceNow, SFTP, and Google Drive (with folder-level selection), in addition to existing custom HTTP connectors.

Custom script pipeline stage

SearchAI ingestion pipelines now support a custom ‘Transform Script’ stage, letting authors write sandboxed JavaScript to transform document content and metadata during ingestion.

Search query debugging controls

The knowledge base Search Test page now includes independent toggles to disable vocabulary resolution and query preprocessing, making it easier to isolate and debug individual stages of the query pipeline.

Knowledge base export in reusable agent modules

Reusable agent modules can now include knowledge base content (indexes, connector configuration, and source metadata) when published, so consumer projects reference the source module’s indexed content without duplicating storage.

Security, identity, and access

Workspace-aware enterprise SSO

Enterprise SSO now supports workspace-level configuration, allowing each workspace to maintain its own SAML/OIDC authentication settings independently of the organization-level SSO configuration, with new admin governance controls.

Custom roles

Workspace owners and admins can now create custom roles with granular permissions beyond the built-in role set and assign them to project members for fine-grained access control.

Expanded Azure Key Vault BYOK authentication options

Bring Your Own Key (BYOK) with Azure Key Vault now supports three authentication methods: typed credential fields (replacing raw JSON configuration), certificate-based service-principal authentication with a pre-save connection test, and Workload Identity Federation for secretless, cross-tenant access.

Per-tenant Platform-Managed key governance

Platform administrators can now view and manage Platform-Managed (Kore-owned) encryption key configuration on a per-tenant basis, with server-side enforcement and audit logging of key lifecycle events.

Custom PII redaction with capture-group backreferences

Custom PII redaction patterns now support regex capture-group backreferences (\1 / $1), enabling partial redaction that preserves non-sensitive parts of matched text — for example, masking all but the last four digits of an account number.

Analytics and insights

Output-item analytics

A new analytics subsystem captures structured data items extracted from agents’ final responses and includes a Studio authoring UI for defining output-item analytics configurations.

Enhanced failure alerting

Aggregate live-session failure alerts now include failure-type summaries.

Custom metrics and dimensions for workflow analytics

Workflow analytics now support custom metrics and dimensions, allowing teams to define and query workflow-specific measurements throughout the analytics pipeline.

Dashboard data export

Analytics dashboard widgets can now be exported as CSV directly from the Studio UI for offline analysis and reporting.

Export feedback

Collected user feedback (ratings, comments, and session references) can now be exported as a .csv file from the Insights → Feedback page for offline analysis.

Per-widget dimension filters

Custom Dashboard widgets now support per-widget dimension filters, allowing different widgets on the same dashboard to apply independent custom-dimension filters.

Administration

Vertex AI via GCP service-account authentication

The platform now supports Google Cloud Vertex AI models — both managed (MaaS) and dedicated-endpoint deployments — using GCP service-account credentials with automatic token refresh, configurable directly in Studio.

Auth profiles can reference environment variables

Auth profile fields can now reference project environment variables (for example, {{env.CLIENT_SECRET}}) instead of hardcoding credentials, so auth profile definitions can be shared safely across environments.

Usability improvement

Active workspace indicator

The account menu now displays the name of the currently active workspace, making it clear which workspace you’re operating in when switching between multiple workspaces.

Original source

Patch Release

This update includes enhancements summarized below.

Public-key JWE authentication for Hosted Exchange Web SDK

Hosted Exchange Web SDK now supports public-key JWE authentication, enabling secure authentication using customer-managed public keys while maintaining compatibility with existing authentication flows.

Environment-specific SAML Entity IDs

Each deployment environment now uses a unique SAML Service Provider (SP) Entity ID, allowing administrators to configure separate SAML applications within their identity provider (IdP) for development, staging, and production. Existing SAML SSO configurations must be updated with the new SP Entity ID after upgrading to this release.

Arch AI Enhancements

Arch AI now provides a more reliable experience for authoring, generation, and evaluation. Improvements include support for larger source documents, more reliable preservation of handoffs across multiple sources, refined validation to reduce unnecessary generation failures, and non-blocking diagnostics to help identify issues without interrupting the generation process.

Language-Aware ON_START Messages

The Web SDK session interaction language is now accessible within the ON_START event, enabling language-specific welcome messages without requiring workflow-based workarounds. This simplifies multilingual agent design, reduces unnecessary latency, and allows startup logic to use standard ABL conditional expressions.

Original source

Major Release

This update includes new features and enhancements summarized below.

Multi-Agent Orchestration

Enhanced Delegation and Handoff Workflows

Multi-agent workflows now support both returning and non-returning delegation patterns, enabling more flexible interruption, escalation, and transfer scenarios. DELEGATE and HANDOFF behaviors are now distinguished, making it easier to implement workflows where conversations either return to the originating flow or are permanently handed off to specialized agents.

Smarter Supervisor Direct Responses

Supervisors can now respond directly to user requests by default, reducing unnecessary routing between agents. This ensures delegated responses are returned to users while still allowing Supervisors to operate as routing-only orchestrators when needed via the canRespondDirectly setting.

Web SDK

Web SDK Multi-Language UI Customization

The Web SDK chat widget now supports language-based customization of UI elements such as chatbot names and typing hints, making it easier to support multilingual deployments.

Simplified Web SDK Integration

Web SDK deployments can now be configured with public API keys and origin allowlists, eliminating the need to generate per-channel embed tokens and simplifying setup with greater control over embedded deployments.

Web SDK Distribution via NPM and CDN

The Web SDK is now available through npm and CDN distribution channels, making it easier to integrate into modern web development workflows and deployment pipelines. The SDK is available here.

Voice

Enhanced SIP Header Support for Voice Channels

SIP header information from inbound and transferred voice calls is now available, enabling routing and business logic based on telephony metadata — including queue information, customer identifiers, language preferences, campaign data, and transfer context.

Security and Compliance

OCI Vault Support for Customer-Managed Encryption Keys

Bring Your Own Key (BYOK) now supports Oracle Cloud Infrastructure (OCI) Vault Key Management Service (KMS), in addition to AWS KMS, Azure Key Vault, Google Cloud KMS, and external REST-compatible KMS, providing greater flexibility to manage customer-controlled encryption keys and compliance requirements.

Original source

Minor Release

This update includes new features and enhancements summarized below.

Search AI and Knowledge Management

Enhanced Search Tool Configuration

Search Tool parameters, such as filters and retrieval settings (for example, topK), can now be configured as mandatory or optional, providing greater control over knowledge retrieval behavior and ensuring that required parameters are consistently applied during tool execution improving retrieval accuracy and reducing reliance on prompt-based instructions.

Custom HTTP Connector for Knowledge Bases

Content can now be ingested into a Knowledge Base from custom HTTP-based data sources. The connector supports scheduled synchronization, schema discovery, field mapping, and secure connectivity options including mTLS, making it easier to integrate proprietary enterprise systems and external data sources with RAG applications. Ingestion workflows also support JavaScript-based content transformations, allowing data to be preprocessed before chunking and indexing.

AI Engineering Tools

Expanded Model Support

The Platform now supports Anthropic's Claude Opus 4.8 model.

Other Improvements

SSO Enhancements

The platform now auto-generates SAML and OIDC endpoint URLs for identity provider configuration. These system-managed URLs ensure consistent setup, reduce manual errors, and are available only to organization owners and admins.

Original source

Minor Release

This update includes new features and enhancements summarized below.

Updates to Web SDK Experience

Improved the Web SDK experience with welcome-message lifecycle enhancements, theme refinements, markdown rendering improvements, and footer-link fixes. Enhanced the Web SDK session handling by preserving and securely resuming idle sessions instead of recreating conversations.

Updates to SearchAI and Knowledge Management

Simplified the SearchAI Knowledge tool DSL, improved knowledge-tool binding and resolution behavior, and enhanced structured-data processing and knowledge ingestion reliability.

Updates to Tool and Gather Definitions

Added support for the effect and provides properties in AgentTool definitions and the satisfiedBy property in GatherField definitions.

Original source

Minor Release

This update includes new features and enhancements summarized below.

Credential Management Updates

Introduced Config Variables ({{config.X}}) and Auth Profiles as the new credential management model, replacing Tool Secrets and the Tool Secrets Management API.

New Memory and Handoff Capabilities

Added support for the per_activation reset mode for session variables. Enhanced handoff workflows with ON_RETURN.set, ON_RETURN.map, and typed handoff history support.

Validation and Tool Execution Enhancements

Added batched LLM validation for fields using VALIDATION_PROCESS: LLM and clarified last__result storage behavior, including store_result semantics.

Project Import and Tooling Improvements

Added support for tool-stub synthesis during project bundle import, allowing tool definitions to be generated from inline agent TOOLS: signatures and re-exported automatically.

ABL Syntax and Field Updates

Updated the ABL expression syntax with method-call operators such as input.contains(), .matches(), and abl.is_number(). Updated the human-agent escalation fields to use user.wants_human_agent.

Original source

Minor Release

This update includes new features and enhancements summarized below.

Tool Readiness Evidence in Arch AI

Arch AI now shows readiness evidence for the tools it adds while building your agents. Each tool is clearly labeled as backed by a live integration or by a stub/mock placeholder, and a project health view surfaces what still needs to be configured before the agent is ready to go live.

More Reliable Agent Generation from SOPs

Generating agents from Standard Operating Procedures (SOPs) now produces more complete agent topologies. Arch AI avoids incomplete builds and validates the generated structure for quality, so SOP-derived projects start from a fuller, more accurate design.

Authoring Evidence in Arch AI Reviews

Arch AI authoring reviews now display evidence badges and incorporate evaluation results. Authoring guidance for constructs such as MEMORY, HANDOFF, TOOLS, GATHER, AGENT, SUPERVISOR, and guardrails is rendered from the Platform’s own construct definitions, giving you clearer, more consistent recommendations as you build.

A Smoother Arch AI Chat Experience

Several reliability improvements make working in the Arch AI chat smoother: errors that have already been resolved (such as model or provider configuration issues) no longer linger in the interface, you can start a new chat even when a previous session ended in an error, and sending a routine message no longer triggers a full refresh of the interface.

DELETE Method for HTTP Tools

HTTP tools now support the DELETE method, alongside GET, POST, PUT, and PATCH. Your agents can now call REST endpoints that remove resources directly from an HTTP tool.
