v0.54.25

More reliable Custom Apps and database relations

Custom App content remains consistent across folders and trash, while delegated database relations can be changed reliably.

  • Improvement Custom App folders and their root documents are managed atomically across Apps and trash, keeping creation, moves, restoration, and deletion consistent.
  • Improvement Delegated changes to database relations are no longer incorrectly blocked by the MCP safety fence.
v0.54.24

Faster Custom App metadata overviews

Batched loading improves responsiveness, scalability, and error isolation for large Custom App metadata overviews.

  • Feature Large Custom App metadata overviews are loaded in batches. This reduces per-item requests, improves responsiveness and scalability, and isolates malformed entries.
v0.54.23

More resilient workspaces during connection errors

Targeted error isolation and bounded recovery keep healthy workspaces usable and interrupted changes moving reliably.

  • Improvement Connection failures in a workspace shard remain isolated to the affected workspace. Stale connections are discarded safely and recovered in a controlled way without disrupting other workspaces.
  • Improvement Workspace-specific server errors no longer put StreamLain globally into offline mode. Affected data is reloaded selectively with bounded retries while healthy workspaces remain usable.
  • Improvement Terminally rejected persisted changes are completed atomically and removed from processing reliably. This prevents retry loops and allows affected connections to recover automatically.
v0.54.22

More stable workspaces, sidebars, and Kanban views

Memory-bounded workspace exports, clearer AI Island behavior, and more stable Kanban interactions improve large and visually demanding workspaces.

  • Feature Large workspace snapshots are exported with bounded memory and backpressure while preserving the existing import format and selective synchronization. Unused files are managed from a server-authoritative inventory with pagination, deletion safety, and clear error and retry handling.
  • Improvement The AI Island is hidden whenever a right sidebar is open. The canonical StreamLain icon appears with inverted contrast in CI blue and white.
  • Improvement The sporadic jump of the Kanban scroll position back to the start is fixed. Remote-selection avatars remain visible, single-rotation drag handles align correctly, and unnecessary off-viewport rendering is reduced.
v0.54.20

More reliable database and multi-document changes

Atomic changes prevent visible partial states, while databases can automatically repair safe row-shard inconsistencies.

  • Improvement Related changes across documents, databases, and relations are now stored atomically and idempotently, preventing visible partial states after interruptions or conflicts.
  • Improvement Databases can now automatically and losslessly repair specific row-shard inconsistencies after full server confirmation. Manual repair remains available whenever the state is not safe for automatic recovery.
v0.54.19

More stable data views and safer local storage

StreamLain 0.54.19 improves database-view stability and surfaces local storage pressure earlier.

  • Improvement Deleted database and Kanban views now disappear reliably from selectors and open settings popups. A removed view no longer remains visible as an empty or stale entry.
  • Improvement The canvas drag handle no longer adds an extra color or background surface on hover. Drag behavior and usability remain unchanged.
  • Improvement Inconsistent row-shard metadata is contained to the affected database block. Users with edit permission receive a clear error and can repair manifest metadata without changing stored row data or inventing missing rows.
  • Feature StreamLain warns earlier when browser-local storage is running low and advises completing synchronization before clearing browser data.
v0.54.18

More stable databases, apps, and AI workflows

Database import and opening are more reliable, while app, agent, and MCP workflows become clearer and more resilient.

  • Feature Edgeless databases open and import data more reliably while reducing unnecessary work during rendering and performance-sensitive updates.
  • Improvement Deleted Custom App folders now complete their deletion lifecycle without leaving an unclear intermediate state.
  • Improvement Agent goals can resume safely from the queue after interruptions, improving recovery of lost state.
  • Feature MCP tools describe their supported inputs and results more clearly, making available capabilities easier to understand.
  • Feature Object configuration responds more directly with lower latency, making editing and feedback feel smoother.
v0.54.17

More stable databases and cleaner canvas connections

Edgeless databases render more deliberately, while MCP connectors expose and choose page anchors that fit the layout.

  • Feature Edgeless databases now wait for shard and view readiness and reduce unnecessary layout and projection work for more stable canvas performance.
  • Feature MCP Canvas connectors expose page anchors and choose geometry-aware defaults when no hint is provided, routing horizontal and vertical connections more cleanly.
v0.54.16

Clearer confirmations and more resilient knowledge notes

MCP actions now follow one confirmation model, while Knowledge Base repairs can be made directly in the existing content.

  • Feature MCP actions now use one consistent confirmation model with traceable states for safe follow-up actions.
  • Improvement Knowledge Base content can be repaired in place, while AI notes remain at the highest logical layer.
v0.54.15

More control for AI, connections, and databases

Managed AI, MCP connectors, and database imports now work with clearer feedback and greater reliability.

  • Feature Managed AI provides clearer access and budget controls for centrally governing AI usage.
  • Improvement MCP connectors preserve their anchors and reconnect more reliably after an interruption.
  • Improvement Database columns align cleanly during import, and completion is confirmed directly after a bulk upload.
v0.54.14

Safer relations and smoother database views

MCP apps handle linked data more reliably, collaborative table editing becomes visible, and large database views respond more smoothly.

  • Feature MCP apps can read bounded relation graphs and update related links atomically, keeping connected data consistent.
  • Feature During collaborative editing, tables in Pages and Notes now show other people's cursor positions directly in the relevant cell.
  • Improvement Large database views on the canvas render content more selectively and remain smoother while scrolling and switching views.
v0.54.11

More reliable AI, Kanban, and database workflows

AI usage is attributed accurately, Kanban groups can be sorted, and databases work more reliably in fullscreen mode.

  • Feature Production AI now uses Requesty as its central policy source and dynamically attributes actual model usage with clear traceability.
  • Feature Kanban groups can now be sorted in ascending or descending order, including groups based on date values.
  • Improvement Kanban scrolling works again in database fullscreen mode, and the accessible close control remains reliably available regardless of layout.
  • Improvement Desktop package smoke checks and Windows package setup are now reproducible.
v0.54.10

Smoother Kanban and canvas interactions

Columns, notes, and databases now respond more reliably while moving, while Custom Apps and snapshots behave more robustly.

  • Improvement New releases now pass reproducible quality, type, build, and relevant backend checks before final online validation.
  • Feature When reordering a Kanban column, the full column follows the pointer while neighboring columns animate the new position before drop; cancellation, read-only mode, and invalid targets remain safe.
  • Improvement The Knowledge Base Custom App can now be created atomically and resumed with its canonical article structure and a working AppBlock, while failures are compensated safely.
  • Improvement Note content and its selection frame now move in sync on every frame instead of jumping apart during drag.
  • Improvement The database toolbar remains correctly attached to its database while panning the canvas and no longer leaves an orphaned overlay.
  • Improvement Empty database shards no longer block snapshot export or import, while real document geometry remains intact.
v0.54.9

Smoother canvas work and more robust databases

Canvas navigation, database views, and connected MCP apps now work together more reliably and directly.

  • Improvement Interrupted Custom App tasks can resume reliably without creating a duplicate app or data source, while existing access boundaries remain intact.
  • Improvement Canvas databases and their table, Kanban, and fullscreen views now use space, heights, and scroll areas more consistently.
  • Improvement The canvas remains more responsive while panning and navigating with interactive content in view.
  • Feature Connected MCP apps can list, add, rename, reorder, update, and delete database select options within existing permission and safety checks.
  • Improvement Spacebar panning, view switching, and the database move grip now respond more reliably, while the grip remains equally usable across zoom levels.
  • Improvement Empty Kanban views keep a stable height and no longer flicker while rendering.
v0.54.8

More direct canvas controls and new database views

Canvas interactions now follow more familiar input patterns, while connected MCP apps can safely manage database views.

  • Feature Mouse wheel, trackpad, and empty-canvas dragging now provide clearer zoom, pan, and multi-selection behavior; selected databases can move together as a group.
  • Feature Connected MCP apps can list, create, rename, configure, and delete table and Kanban views, while existing permissions, confirmations, and last-view protection remain active.
  • Feature First-run setup now separates the anonymous error-reporting decision from the welcome tutorial, with clearer details and an easier-to-find setting under About StreamLain.
  • Improvement The canvas tool area now labels its entry clearly as “Databases and Automations”.
v0.54.7

More reliable database actions through MCP

Connected MCP apps and Custom Apps can reliably edit database rows again.

  • Improvement Rows can be added, updated, converted, and deleted without being incorrectly rejected by the mutation safety fence.
  • Security Existing permission, confirmation, and safety checks remain fully active.
v0.54.6

A clearer start and more robust MCP reads

Getting started is more focused, settings are easier to reach, and MCP read operations no longer alter write state.

  • Feature The welcome dialog now focuses on the primary entry point and optional anonymous error diagnostics, while product analytics remain disabled.
  • Feature About StreamLain remains available at the bottom of settings, and shared sidebar boundaries are visually clearer.
  • Improvement MCP read tools traverse folders and content without creating unintended write or mutation state.
