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 MCPcreate-workspacevia optionalhostedZoneId. - 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, andcollectionsURL 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-cmsinvitations. - Documents the Ask Usable beta and invitation-revocation changes.
v1.193.0 (2026-06-28)

- MCP app widgets now publish domain metadata (

v1.189.1 (2026-06-22)
