--- title: "Release 5.7.0" description: "Instance knowledge base with step-by-step tours, web research in the AI Assistant, registered-contact filters, and fixes across Operator Line, settings, and channels." --- # Release 5.7.0 > Your team documents internal workflows in **Knowledge Base**, launches tours from articles, and—when an administrator allows it—the AI Assistant can check public vendor documentation without leaving Constructor. ## Constructor — instance knowledge base **New** - **Knowledge Base module.** After an administrator enables it, your team stores internal instructions, specs, and articles in Constructor: version history with restore, role-based access, pinned items on the welcome dashboard, and a Help menu entry. - **Instance tours.** A dedicated **Instance tours** area: list, search, draft/ready status, archive; YAML editor with validation before save; import and export of `.tour.yaml` files. - **Tour in an article.** While editing a document — **Insert tour**; preview shows a **Launch tour** card next to the instructions. - **Role-based access.** New tours are restricted by default; management uses **Manage instance UI tours** under **Settings → Roles**. **Improved** - **Card statuses.** Draft, archived, or no-access tours show a clear state instead of a misleading launch button. ## AI Assistant **New** - **Web search and URL fetch.** When an administrator allows it, the assistant can search the public internet or summarize a single public web page—separate from ConnectiveOne documentation and your instance knowledge base. - **Step-by-step output.** The chat shows **Web Search** / **Fetch URL** steps while the request runs; in **Plan** mode you confirm a research plan first. **Improved** - **Off by default.** Both capabilities require an instance toggle **and** a role permission—new users do not get web access automatically. ## Operator Line **Improved** - **Transfer to online operators only.** If [operator settings](../settings/how-to/configure-operators.md) have **Show only online operator when transferring dialogues** enabled, the transfer modal now lists online operators only—the option previously had no effect on the picker. - **Translate long messages.** The **Translate** action stays available for texts within the instance AI input limit inclusive—instead of blocking too early on a hardcoded threshold. - **Settings tables in Operator Line.** Lists for tags, priorities, skill groups, metrics, calendars, and statuses fill the viewport and scroll—instead of clipping at a fixed ~300 px height. - **AI Assistant on mobile.** On narrow screens the assistant opener moved to the **?** Help menu so the top toolbar stays usable. **Fixed** - **Auto-connect after failure.** If automatic operator assignment fails, the chat returns to distribution without waiting up to three minutes—fewer stuck dialogs in the queue on multi-node instances. - **Dialog export.** Exporting the chatroom list with filters completes successfully again—it previously failed with an internal error. ## Clients module **New** - **Registered contact.** The client list has a column and filter for whether at least one contact left a phone, email, or sign-in (vs. an anonymous visitor only). - **Visitors without a contact.** A separate list mode shows channel visitors not yet linked to a client record. **Improved** - **Client list search.** Finds records by chat_id, dialog number, and appeal; in visitor mode—by chat_id and bot_id. ## Settings **Improved** - **Users.** On edit, password fields stay collapsed by default—browser autofill no longer breaks saving the user card. - **Roles.** Draft state for a new or edited role survives accidental drawer close; unsaved changes are visible until you save. **Fixed** - **Role deletion.** After you delete a role it disappears from the list and the system—the server path previously could fail to complete removal. ## Notification Center **Improved** - **SLA and normative response alerts.** You can subscribe to SLA and normative notification types in profile and operator settings—new operators no longer receive them until they opt in. - **Bell content.** SLA and normative alerts show topic, client, ticket title, and metric or time-in-status context. - **No duplicates.** With Notification Center enabled, one event no longer creates two bell entries. ## Broadcast **Improved** - **Broadcast v1 log tab.** The log tab shows **loaded / total** (for example, 50/200); **Load more** disables when every row is already loaded. **Fixed** - **Message from the correct bot.** If a customer wrote to two bots, a broadcast sends from the bot that handled the dialog—not from another bot in the same database. ## Channels **Improved** - **Typing indicator in Microsoft Teams.** When a reply takes several seconds (AI, Fast Line, or a scenario step with typing), the customer in Teams sees the bot typing—like Telegram or the widget. **Fixed** - **PDF and documents in Telegram.** PDF and other files arrive as Telegram documents—not as a link that fails with “wrong type of the web page content”. **New** - **Instagram Ads context.** When an administrator enables the instance option, ad context from Instagram Ads is merged into the customer’s next message in the scenario (off by default). ## Scenario Builder and tickets **Fixed** - **Ticket description from an action block.** If `tickets_create` / `tickets_create_v2` pass `ticket_description` in the node JSON, the description lands on the ticket—no need to store it separately in dialog state. - **SLA after ticket completion.** When a ticket moves to a completion status, SLA timers stop fully—without stray background triggers. - **Tags in operator_panel actions.** Placeholders in `tag_ids` resolve correctly before tags are applied to the dialog. ## Custom Data **Fixed** - **Table creation.** If schema sync fails after saving metadata, the Custom Data record rolls back—you no longer keep an empty table shell in the list. ## Fast Line **Fixed** - **Transfer to operator.** When no operator is available, the scenario gets a clear transfer outcome—without hanging on the wait step. ## Integrations — Cases API **New** - **External Cases API.** For CRM or Service Desk integrations: filtered case list, details, message history, and operator replies through a dedicated endpoint set with predictable error codes. - **External ID on ticket create.** Create-ticket requests can include `external_id`—a retry with the same id does not create a duplicate case after a network repeat. - **HTML in API messages.** HTML message types pass through a restricted safe tag set; unsafe content is stripped. **Improved** - **Delivery before persistence.** If the channel (messenger, email, etc.) rejects an operator reply, the API returns a clear error—instead of a system “success” without customer delivery. - **Rate limits.** New endpoints have request limits; when exceeded, the response includes an error code and a hint to retry later. **Please note (integrators)** - Cases API access requires an integration user with the right scope (bot, subjects, permissions). Ticket create **without** `external_id` behaves as before—the response format is unchanged. ## Please note - **Knowledge Base** and **Instance tours** appear only after an administrator enables them—see [configure instance settings](../settings/how-to/configure-instance.md). - **Web search and URL fetch** in the AI Assistant require separate instance and role permissions. - **Instagram Ads context** and updated **Users / Roles** screens are optional; check with your instance administrator before expecting them in your account. - **Show only online when transferring** works only if that option is already enabled in operator settings. ## Related documentation - [What is the instance knowledge base](../constructor/explanation/what-is-instance-knowledge-base.md) - [Use the instance knowledge base](../constructor/how-to/use-instance-knowledge-base.md) - [What are instance tours](../constructor/explanation/what-is-instance-tours.md) - [Use instance tours](../constructor/how-to/use-instance-tours.md) - [AI Assistant overview](../learn/instance-agent/instance-agent-overview.md) - [Enable web search and URL fetch](../constructor/how-to/use-ai-assistant-web-research.md) - [Registered contacts and visitors](../broadcastusers/explanation/registered-contact-and-visitors.md) - [View visitors without a contact](../broadcastusers/how-to/view-visitors-without-contacts.md) - [Enable Notification Center](../notifications/how-to/enable-notification-center.md) - [Configure a notification type](../notifications/how-to/configure-notification-type.md) - [Configure operators](../settings/how-to/configure-operators.md) - [Configure instance settings](../settings/how-to/configure-instance.md) - [Use the API](../integrations/how-to/use-api.md) - [Integrator hub](../integrations/integrator-hub.md)
