Changelog

What's new

Three new connectors

• Slack — send messages, list channels, get channel history, add emoji reactions, upload files (5 methods)
• Notion — search pages/databases, get/create/update pages, query databases, append blocks (6 methods)
• Stripe — list/create/get customers, create payment intents, list/get payments, list/cancel subscriptions, create invoices (9 methods)

All three connectors support simulation mode, structured diffs, and consistent error handling with httpx HTTPStatus and network error recovery.

Version History page

• /studio/:id/history — full snapshot timeline of every workflow definition change
• Click any version to expand a JSON diff of the definition at that point
• One-click restore — current state is snapshotted before restoring, so nothing is ever lost

Fixes

• Auth hardening — OIDC token handler now correctly calls create_access_token(user.id) (was passing a dict)
• Route ordering — /me/context endpoints now declared before /me/:user_id to prevent FastAPI wildcard shadowing
• Ownership guards — alert list, delete, and test endpoints now enforce user_id ownership
• Audit log — removed from __future__ import annotations (caused FastAPI ForwardRef type resolution errors)

What's new

Knowledge Base (/memory)

• Store facts, documents, and snippets that any workflow can query
• KnowledgeConnector — search and get methods available in any LLM or Tool step
• Full CRUD at POST/GET/DELETE /knowledge

Workflow Optimization

• GET /workflows/:id/optimize — static analysis of run history to surface dead steps, flaky steps, always-succeeding steps, and slow steps
• Severity levels: warning and info
• Shown in the Monitor page as actionable suggestions

Compile from Examples

• POST /workflows/compile-from-examples — describe a workflow by input/output pairs; Claude infers the intent and compiles a full workflow definition
• Useful for non-technical users who know what they want the output to look like

Agents

• Agent model, CRUD API, and full agents UI (/agents, /agents/:id)
• Config, memory, and runs tabs per agent
• Marketplace view with pre-built agent cards

Auth pages

• /auth/login — Google OAuth + email dev-login
• /auth/signup — account creation flow
• Sidebar hidden for /auth/* routes

Changelog page

• /changelog — versioned release notes with markdown bodies and tag pills
• RSS feed at /changelog/rss.xml

What's new

• Landing page at / — hero, feature grid, example workflows, connector cloud, CTA
• Pricing page at /pricing — Free / Pro / Self-Host tier comparison with FAQ accordion
• Login page at /auth/login — Google OAuth primary, email dev-login secondary
• Template library at /templates — API-driven + static templates, DAG preview modal, search and category filters
• Connector Hub redesign — category tabs (Google, Messaging, Finance, Built-in), live OAuth status badges, custom connector request entry
• Studio split — /studio is now a workflow card list; /studio/new and /studio/:id are the editor routes
• Settings hub — profile editor, API keys placeholder, self-host ENV checker, billing tier cards

Improvements

• Sidebar now skipped for marketing and auth routes (/, /pricing, /auth/*)
• Run list now shows workflow name column, date presets, bulk delete, and replay button
• Dashboard stats strip wired to live run counts

What's new

• WhatsApp node shows an inline phone number field in the DAG — no modal needed for the most common configuration
• ELK edge validation — dangling edges to non-existent node IDs are silently pruned before layout

Fixes

• Stale closure bug in WorkflowDAG — ownerNumber and onSaveConfig are now included in useMemo deps; handleSaveConfig wrapped in useCallback
• runStatus changes no longer cause ELK re-layout churn (status excluded from layout dep array)
• View-mode dragging disabled — nodes are fixed in view-only contexts
• foreach step IDs now correctly scoped inside the loop body
• Missing code StepType added to DAG node renderer

What's new

• ELK.js auto-layout — workflow DAGs are automatically arranged using layered graph layout
• Per-type node components — ToolNode, LLMNode, BranchNode, ForeachNode, WaitNode, CodeNode with distinct visual treatments
• Inline node editing — click any node to open its config panel without leaving the DAG view
• Node status overlays — live step status (running, completed, failed, waiting) rendered as coloured rings on nodes
• useRunStatus hook — WebSocket subscription for per-step status updates

Improvements

• Improved layout quality: reversed edges handled, port assignments per step type
• Simulated runs no longer spam layout recalculations

What's new

• Orchestrator agent decomposes the prompt into step intents in parallel
• Step generator agents — one Claude call per step, run concurrently
• Data flow resolver — wires next_step edges and fixes input_expr references between steps
• SSE streaming at /compile/stream — progress events for each compilation stage
• Per-step harness validation — each generated step is individually type-checked before assembly

Improvements

• Single-shot fallback when multi-agent compile fails
• Rich context builder generates capability cards for each connector

What's new

• Telegram bot persona — handle_telegram_message() interprets natural language messages and triggers workflow compilation or run
• Plaid banking connector — list_transactions, get_balance, get_institutions; defaults to sandbox environment
• WebSocket run monitoring at /ws/runs/{run_id} — real-time step-by-step execution events
• Non-blocking run endpoint — POST /workflows/{id}/run dispatches to FastAPI BackgroundTasks and returns immediately

Fixes

• Background tasks open their own AsyncSessionLocal session (was sharing request session, causing post-response errors)

What's new

• Run history API — cursor-based pagination for GET /runs, filterable by workflow and status
• waiting status — runs pause at WaitStep approval gates; WebSocket stays open
• Policy layer — OutboundPolicy enforces WhatsApp number allowlists and confidence thresholds before any outbound action
• Simulation mode — simulation=true fires every step without calling real external APIs; diffs recorded for review

Improvements

• Run monitoring dashboard wired to live WebSocket events
• LogEntry enriched with step_type, skipped, gated, gated_reason fields
