    Usable public changelog through v1.198.1

    This changelog summarizes released, user-facing and developer-facing changes. It excludes private implementation details, deployment topology, secrets, and unreleased behavior.

    v1.198.1 (2026-07-03)

    New features

    • Adds Hosted Zones for Pro organizations: owners/admins can register Leaf endpoints, inspect zone status/heartbeat/storage/queue detail, copy setup bundles, and regenerate one-time Leaf API keys.
    • Adds hosted-zone workspace placement in the dashboard, REST POST /api/workspaces, and MCP create-workspace via optional hostedZoneId.
    • Adds hosted-zone REST routes for organization zone listing/registration/key regeneration, Leaf registration, heartbeat, validation, and browser bearer-token handoff.
    • Makes the Cloud/Leaf boundary visible: Cloud owns organization/tier/workspace-registry metadata; Leaf owns private fragment data, search, local embeddings, remote MCP, and encrypted private event payloads. Hosted-zone V1 does not support file payload workflows.
    • Adds Usable Chat context links from workspace, fragment, and collection pages using workspaces, fragments, and collections URL query parameters.
    • Improves fragment-detail rendering for stacked frontmatter, headings, code blocks, and narrow screens.

    v1.195.0 (2026-07-02)

    New features

    • Adds a Sort by control for workspace fragment-type pills. Users can keep the default order or sort by name, color, or most-used count.
    • Adds Connect MCP to the dashboard home page and simplifies the MCP connection dialog around the remote MCP URL plus OAuth 2.1 browser sign-in.
    • Adds public client snippets for Claude Code, Claude Desktop, Codex, OpenCode, and generic Streamable HTTP MCP clients.
    • Makes dashboard Ask Usable prompt chips submit immediately.
    • Updates REST/OpenAPI creation-source enums so memory fragments and search filters recognize createdVia: "symlink".
    • Hardens symlink rule reprocess: detects enabled rule cycles, skips symlink children, returns a processing message when synchronous reprocess would create more than 50 fragments.

    v1.194.4 (2026-06-29)

    • Adds a dedicated interactive API reference page at /docs/api-reference.
    • Improves Ask Usable embed auth resilience: proactive token refresh, parent-session MCP tool bridging, native UI request handling.
    • Updates workspace invitation email branding with the flat Usable logo asset.

    v1.194.0 (2026-06-28)

    • Adds CMS-aware workspace invitation context for usable-cms invitations.
    • Documents the Ask Usable beta and invitation-revocation changes.

    v1.193.0 (2026-06-28)

    • Adds the Ask Usable embedded assistant beta for users with the ask-usable-embed-chat beta feature.
    • The assistant appears as a dashboard bubble, expands to a panel, and can open a canvas view.

    v1.192.2 (2026-06-26)

    • MCP app widgets now publish domain metadata (_meta.ui.domain) for widget host clients.

    v1.192.1

    • MCP create-memory-fragment fragment-type failures now return tool-level errors (result.isError: true) instead of transport errors.

    v1.192.0

    • Admin organization invitations: invite members by email, view pending invitations, resend, and revoke.

    v1.191.0

    • Workspace auto-link rules: match source-workspace fragment tags and create symlinked fragments in a target workspace. Includes preview, create, enable/disable, delete, and reprocess flows.

    v1.189.1 (2026-06-22)

    • Workspace email notification delivery is more resilient: delivery-event/audit writes are best-effort.
    • Billing draft invoice recovery: stale draft invoice references can be replaced instead of failing.
    • AI/Bedrock context-limit handling: wider safety margin for near-window prompts.
    • Fragment processing reliability: expired-lock jobs can fail/quarantine after bounded retries.

    v1.189.0 (2026-06-19)

    • Workspace email notifications added.

    v1.186.0 (2026-06-17)

    • Marketplace Connect modal widened; Device Code flow snippet added.

    v1.185.0 (2026-06-16)

    • OAuth Device Code (RFC 8628) grant type added for applications.

    v1.184.0 (2026-06-16)

    • MCP public workspace registry search and subscribe tools added: search-public-workspaces, subscribe-to-workspace.

    v1.183.0 (2026-06-16)

    • MCP workspace create/update tools exposed: create-workspace, update-workspace.

    v1.182.3 (2026-06-12)

    • Fixed MCP get-memory-fragment-content output to avoid duplicate fragment body text.

    v1.182.2 (2026-06-12)

    • MCP accepts hyphen, slash, and dot in branch names and tags.
