 ## [Unreleased]
 
-## [2.40.2] - 2026-03-22
-
-### Fixed
-
-- **Double URL-encoding of `filter` and `sortBy` in `getRows`/`deleteRows`**: Moved `encodeURIComponent()` from handler layer to a custom `paramsSerializer` in the API client. Handlers were encoding values before passing them as Axios params, causing double-encoding (`%257B` instead of `%7B`). Handlers now pass raw values; the API client encodes once via `serializeDataTableParams()`
-- **`updateTable` documentation clarified**: Explicitly notes that only renaming is supported (no column modifications via public API)

-## [2.40.1] - 2026-03-21
-
-### Fixed
-
-- **`n8n_manage_datatable` row operations broken by MCP transport serialization**: `data` parameter received as string instead of JSON — added `z.preprocess` coercers for array/object/filter params
-- **`n8n_manage_datatable` filter/sortBy URL encoding**: n8n API requires URL-encoded query params — added `encodeURIComponent()` for filter and sortBy in getRows and deleteRows (revised in 2.40.2 to move encoding to API client layer)
-- **`json` column type rejected by n8n API**: Removed `json` from column type enum (n8n only accepts string/number/boolean/date)
-- **Garbled 404 error messages**: Fixed `N8nNotFoundError` constructor — API error messages are now passed through cleanly instead of being wrapped in "Resource with ID ... not found"

-### Changed
-
-- **`n8n_manage_datatable` MCP tool** (replaces `n8n_create_data_table`): Full data table management covering all 10 n8n data table API endpoints
-  - **Table operations**: createTable, listTables, getTable, updateTable, deleteTable
-  - **Row operations**: getRows, insertRows, updateRows, upsertRows, deleteRows
-  - Filter system with and/or logic and 8 condition operators (eq, neq, like, ilike, gt, gte, lt, lte)
-  - Dry-run support for updateRows, upsertRows, deleteRows
-  - Pagination, sorting, and full-text search for row listing
-  - Shared error handler and consolidated Zod schemas for consistency
-  - 9 new `N8nApiClient` methods for all data table endpoints
-- **`projectId` parameter for `n8n_create_workflow`**: Create workflows directly in a specific team project (enterprise feature)

-  - New `transferWorkflow` operation type with `destinationProjectId` parameter
-  - Calls `PUT /workflows/{id}/transfer` via dedicated API after workflow update
-  - Proper error handling: returns `{ success: false, saved: true }` when transfer fails after update
-  - Transfer executes before activation so workflow is in target project first
-  - Zod schema validates `destinationProjectId` is non-empty
-  - Updated tool description and documentation to list the new operation
-  - `inferIntentFromOperations` returns descriptive intent for transfer operations
-  - `N8nApiClient.transferWorkflow()` method added

-## [2.37.3] - 2026-03-15
-
-### Fixed
-
-- **updateNode `name`/`id` field normalization**: LLMs sending `{type: "updateNode", name: "Code", ...}` instead of `nodeName` no longer get "Node not found" errors. The Zod schema now normalizes `name` → `nodeName` and `id` → `nodeId` for node-targeting operations (updateNode, removeNode, moveNode, enableNode, disableNode)
-- **AI connection types in disconnected-node detection** (Issue #581): Replaced hardcoded 7-type list with dynamic iteration over all connection types present in workflow data. Nodes connected via `ai_outputParser`, `ai_document`, `ai_textSplitter`, `ai_agent`, `ai_chain`, `ai_retriever` are no longer falsely flagged as disconnected during save
-- **Connection schema and reference validation** (Issue #581): Added `.catchall()` to `workflowConnectionSchema` for unknown AI connection types, and extended connection reference validation to check all connection types (not just `main`)
-- **autofix `filterOperationsByFixes` ID-vs-name mismatch**: Typeversion-upgrade operations now include `nodeName` alongside `nodeId`, and the filter checks both fields. Previously, `applyFixes=true` silently dropped all typeversion fixes because `fixedNodes` contained names but the filter only checked `nodeId` (UUID)

-- **Code validator `$()` false positive** (Issue #294): `$('Previous Node').first().json` no longer triggers "Invalid $ usage detected" warning. Added `(` and `_` to the regex negative lookahead to support standard n8n cross-node references and valid JS identifiers like `$_var`
-- **Code validator helper function return false positive** (Issue #293): `function isValid(item) { return false; }` no longer triggers "Cannot return primitive values directly" error. Added helper function detection to skip primitive return checks when named functions or arrow function assignments are present
-- **Null property removal in diff engine** (Issue #611): `{continueOnFail: null}` no longer causes Zod validation error "Expected boolean, received null". The diff engine now treats `null` values as property deletion (`delete` operator), and documentation updated from `undefined` to `null` for property removal

-- **IMAP Email Trigger activation** (Issue #538): `n8n-nodes-base.emailReadImap` and other IMAP-based polling triggers are now recognized as activatable triggers, allowing workflow activation
-- **AI tool description false positives** (Issue #477): Validators now check `description` and `options.description` in addition to `toolDescription`, fixing false `MISSING_TOOL_DESCRIPTION` errors for toolWorkflow, toolCode, and toolSerpApi nodes
-- **n8n_create_workflow undefined ID** (Issue #602): Added defensive check for missing workflow ID in API response with actionable error message
-- **Flaky CI performance test**: Relaxed bulk insert ratio threshold from 15 to 20 to accommodate CI runner variability

-- **Unary operator sanitization** (Issue #592): Added missing `empty`, `notEmpty`, `exists`, `notExists` operators to the sanitizer's unary operator list, preventing IF/Switch node corruption during partial updates
-- **Positional connection array preservation** (Issue #610): `removeNode` and `cleanStaleConnections` now trim only trailing empty arrays, preserving intermediate positional indices for IF/Switch multi-output nodes
-- **Scoped sanitization**: Auto-sanitization now only runs on nodes that were actually added or updated, preventing unrelated nodes (e.g., HTTP Request parameters) from being silently modified
-- **Activate/deactivate 415 errors** (Issue #633): Added empty body `{}` to POST calls for workflow activation/deactivation endpoints
-- **Zod error readability** (Issue #630): Validation errors now return human-readable `"path: message"` strings instead of raw Zod error objects
-- **updateNode error hints** (Issue #623): Improved error message when `updates` parameter is missing, showing correct structure with `nodeId`/`nodeName` and `updates` fields
-- **removeConnection after removeNode** (Issue #624): When a node was already removed by a prior `removeNode` operation, the error message now explains that connections were automatically cleaned up
-- **Connection type coercion** (Issue #629): `sourceOutput` and `targetInput` are now coerced to strings, handling numeric values (0, 1) passed by MCP clients
-
-### Added
-
-- **`saved` field in responses** (Issue #625): All `n8n_update_partial_workflow` responses now include `saved: true/false` to distinguish whether the workflow was persisted to n8n
-- **Tag operations via dedicated API** (Issue #599): `addTag`/`removeTag` now use the n8n tag API (`PUT /workflows/{id}/tags`) instead of embedding tags in the workflow body, fixing silent tag failures. Includes automatic tag creation, case-insensitive name resolution, and last-operation-wins reconciliation for conflicting add/remove
-- **`updateWorkflowTags` API client method**: New method on `N8nApiClient` for managing workflow tag associations via the dedicated endpoint
-- **`operationsApplied` in top-level response**: Promoted from nested `details` to top-level for easier consumption by MCP clients

-
-### Added
-
-- **Conditional branch fan-out detection** (`CONDITIONAL_BRANCH_FANOUT`): Warns when IF, Filter, or Switch nodes have all connections crammed into `main[0]` with higher-index outputs empty, which usually means all target nodes execute together on one branch while other branches have no effect
-  - Detects IF nodes with both true/false targets on `main[0]`
-  - Detects Filter nodes with both matched/unmatched targets on `main[0]`
-  - Detects Switch nodes with all targets on output 0 and other outputs unused
-  - Skips warning when fan-out is legitimate (higher outputs also have connections)
-  - Skips warning for single connections (intentional true-only/matched-only usage)
-
-### Changed
-
-- **Refactored output index validation**: Extracted `getShortNodeType()` and `getConditionalOutputInfo()` helpers to eliminate duplicated conditional node detection logic between `validateOutputIndexBounds` and the new `validateConditionalBranchUsage`

-- **Connection validation: detect broken/malformed workflow connections** (Issue #620):
-  - Unknown output keys (`UNKNOWN_CONNECTION_KEY`): Flags invalid connection keys like `"0"`, `"1"`, `"output"` with fix suggestions (e.g., "use main[1] instead" for numeric keys)
-  - Invalid type field (`INVALID_CONNECTION_TYPE`): Detects invalid `type` values in connection targets (e.g., `"0"` instead of `"main"`)
-  - Output index bounds checking (`OUTPUT_INDEX_OUT_OF_BOUNDS`): Catches connections using output indices beyond what a node supports, with awareness of `onError: 'continueErrorOutput'`, Switch rules, and IF/Filter nodes
-  - Input index bounds checking (`INPUT_INDEX_OUT_OF_BOUNDS`): Validates target input indices against known node input counts (Merge=2, triggers=0, others=1)
-  - BFS-based trigger reachability analysis: Replaces simple orphan detection with proper graph traversal from trigger nodes, flagging unreachable subgraphs
-  - Flexible `WorkflowConnection` interface: Changed from explicit `main?/error?/ai_tool?` to `[outputType: string]` for accurate validation of all connection types

-- **Comprehensive parameter type coercion for Claude Desktop / Claude.ai** (Issue #605): Expanded the v2.35.4 fix to handle ALL type mismatches, not just stringified objects/arrays. Testing revealed 6/9 tools still failing in Claude Desktop after the initial fix.
-  - Extended `coerceStringifiedJsonParams()` to coerce every schema type: `string→number`, `string→boolean`, `number→string`, `boolean→string` (in addition to existing `string→object` and `string→array`)
-  - Added top-level safeguard to parse the entire `args` object if it arrives as a JSON string
-  - Added `[Diagnostic]` section to error responses showing received argument types, enabling users to report exactly what their MCP client sends
-  - Added 9 new unit tests (24 total) covering number, boolean, and number-to-string coercion

-
-- **Defensive JSON.parse for stringified object/array parameters** (Issue #605): Claude Desktop 1.1.3189 serializes JSON object/array MCP parameters as strings, causing ZodError failures for ~60% of tools that accept nested parameters
-  - Added schema-driven `coerceStringifiedJsonParams()` in the central `CallToolRequestSchema` handler
-  - Automatically detects string values where the tool's `inputSchema` expects `object` or `array`, and parses them back
-  - Safe: prefix check before parsing, type verification after, try/catch preserves original on failure
-  - No-op for correct clients: native objects pass through unchanged
-  - Affects 9 tools with object/array params: `validate_node`, `validate_workflow`, `n8n_create_workflow`, `n8n_update_full_workflow`, `n8n_update_partial_workflow`, `n8n_validate_workflow`, `n8n_autofix_workflow`, `n8n_test_workflow`, `n8n_executions`

-- **Fixed node loader for langchain package**: Adapted node loader to bypass restricted package.json `exports` field in @n8n/n8n-nodes-langchain >=2.9.0, resolving node files via absolute paths instead of `require.resolve()`
-- **Fixed community doc generation for cloud LLMs**: Added `N8N_MCP_LLM_API_KEY`/`OPENAI_API_KEY` env var support, switched to `max_completion_tokens`, and auto-omit `temperature` for cloud API endpoints
-- Rebuilt node database with 1,236 nodes (673 from n8n-nodes-base, 133 from @n8n/n8n-nodes-langchain, 430 community)

-- **MCP Apps: Disable non-rendering apps in Claude.ai**: Disabled 3 MCP Apps (workflow-list, execution-history, health-dashboard) that render as collapsed accordions in Claude.ai, and removed `n8n_deploy_template` tool mapping which renders blank content. The server sets `_meta` correctly on the wire but the Claude.ai host ignores it for these tools. The 2 working apps (operation-result for 6 tools, validation-summary for 3 tools) remain active. Disabled apps can be re-enabled once the host-side issue is resolved.

-
-- **MCP Apps: Fix UI not rendering for some tools in Claude**: Added legacy flat `_meta["ui/resourceUri"]` key alongside the nested `_meta.ui.resourceUri` in tool definitions. Claude.ai reads the flat key format; without it, tools like `n8n_health_check` and `n8n_list_workflows` showed as collapsed accordions instead of rendering their rich UI apps. Both key formats are now set by `injectToolMeta()`, matching the behavior of the official `registerAppTool` helper from `@modelcontextprotocol/ext-apps/server`.

-### Added
-
-- **3 new MCP Apps**: workflow-list (compact table with status/tags), execution-history (status summary bar + execution table), health-dashboard (connection status, versions, performance metrics)
-- **Enhanced operation-result**: operation-aware headers (create/update/delete/test/deploy), detail panels with workflow metadata, copy-to-clipboard for IDs/URLs, autofix diff viewer
-- **CopyButton shared component**: reusable clipboard button with visual feedback
-- **Local preview harness** (`ui-apps/preview.html`): test all 5 apps with mock data, dark/light theme toggle, JSON-RPC protocol simulation
-- **Expanded shared types**: TypeScript types for workflow-list, execution-history, and health-dashboard data

-  - `UIMetadata.ui.app` renamed to `UIMetadata.ui.resourceUri`
-  - Added `_meta` field to `ToolDefinition` type
-  - Added `UIAppRegistry.injectToolMeta()` method for enriching tool definitions
-  - UI apps now use `@modelcontextprotocol/ext-apps` `App` class instead of `window.__MCP_DATA__`
-  - Updated `ReadResource` URI parser to match new `ui://` scheme

-
-## [2.34.0] - 2026-02-07
-
-### Added
-
-- **MCP Apps**: Rich HTML UIs rendered by MCP hosts alongside tool results via `_meta.ui` and the MCP resources protocol
-  - Server-side UI module (`src/mcp/ui/`) with tool-to-UI mapping and `_meta.ui` injection
-  - `UIAppRegistry` static class for loading and serving self-contained HTML apps
-  - `UI_APP_CONFIGS` mapping tools to their corresponding UI apps
-
-- **Operation Result UI**: Visual summary for workflow operation tools
-  - Status badge, operation type, workflow details card
-  - Expandable sections for nodes added, modified, and removed
-  - Mapped to: `n8n_create_workflow`, `n8n_update_full_workflow`, `n8n_update_partial_workflow`, `n8n_delete_workflow`, `n8n_test_workflow`, `n8n_autofix_workflow`, `n8n_deploy_template`
-
-- **Validation Summary UI**: Visual summary for validation tools
-  - Valid/invalid badge with error and warning counts
-  - Expandable error list with type, property, message, and fix
-  - Expandable warning list and suggestions
-  - Mapped to: `validate_node`, `validate_workflow`, `n8n_validate_workflow`
-
-- **React + Vite Build Pipeline** (`ui-apps/`):
-  - React 19, Vite 6, vite-plugin-singlefile for self-contained HTML output
-  - Shared component library: Card, Badge, Expandable
-  - `useToolData` hook for reading data from `window.__MCP_DATA__` or embedded JSON
-  - n8n-branded dark theme with CSS custom properties
-  - Per-app builds via `APP_NAME` environment variable
-
-- **MCP Resources Protocol**: Server now exposes `resources` capability
-  - `ListResources` handler returns available UI apps
-  - `ReadResource` handler serves self-contained HTML via `n8n-mcp://ui/{id}` URIs
-
-- **New Scripts**:
-  - `build:ui`: Build UI apps (`cd ui-apps && npm install && npm run build`)
-  - `build:all`: Build UI apps then server (`npm run build:ui && npm run build`)
-
-### Changed
-
-- **MCP Server**: Added `resources: {}` to server capabilities alongside existing `tools: {}`
-- **Tool Responses**: Tools with matching UI apps now include `_meta.ui.app` URI pointing to their visual representation
-- **Graceful Degradation**: Server starts and operates normally without `ui-apps/dist/`; UI metadata is only injected when HTML is available

-## [2.33.6] - 2026-02-06
-
-### Changed
-
-- Updated n8n from 2.4.4 to 2.6.3
-- Updated n8n-core from 2.4.2 to 2.6.1
-- Updated n8n-workflow from 2.4.2 to 2.6.0
-- Updated @n8n/n8n-nodes-langchain from 2.4.3 to 2.6.2
-- Rebuilt node database with 806 nodes (544 from n8n-nodes-base, 262 from @n8n/n8n-nodes-langchain)
-- Updated README badge with new n8n version
-
-## [2.33.5] - 2026-01-23
-
-### Fixed
-
-- **Critical memory leak: per-session database connections** (Issue #542): Fixed severe memory leak where each MCP session created its own database connection (~900MB per session)
-  - Root cause: `N8NDocumentationMCPServer` called `createDatabaseAdapter()` for every new session, duplicating the entire 68MB database in memory
-  - With 3-4 sessions, memory would exceed 4GB causing OOM kills every ~20 minutes
-  - Fix: Implemented singleton `SharedDatabase` pattern - all sessions now share ONE database connection
-  - Memory impact: Reduced from ~900MB per session to ~68MB total (shared) + ~5MB per session overhead
-  - Added `getSharedDatabase()` and `releaseSharedDatabase()` for thread-safe connection management
-  - Added reference counting to track active sessions using the shared connection
-
-- **Session timeout optimization**: Reduced default session timeout from 30 minutes to 5 minutes
-  - Faster cleanup of stale sessions reduces memory buildup
-  - Configurable via `SESSION_TIMEOUT_MINUTES` environment variable
-
-- **Eager instance cleanup**: When a client reconnects, previous sessions for the same instanceId are now immediately cleaned up
-  - Prevents memory accumulation from reconnecting clients in multi-tenant deployments
-
-- **Telemetry event listener leak**: Fixed event listeners in `TelemetryBatchProcessor` that were never removed
-  - Added proper cleanup in `stop()` method
-  - Added guard against multiple `start()` calls
-
-### Added
-
-- **New module: `src/database/shared-database.ts`** - Singleton database manager
-  - `getSharedDatabase(dbPath)`: Thread-safe initialization with promise lock pattern
-  - `releaseSharedDatabase(state)`: Reference counting for cleanup
-  - `closeSharedDatabase()`: Graceful shutdown for process termination
-  - `isSharedDatabaseInitialized()` and `getSharedDatabaseRefCount()`: Monitoring helpers
-
-### Changed
-
-- **`N8NDocumentationMCPServer.close()`**: Now releases shared database reference instead of closing the connection
-- **`SingleSessionHTTPServer.shutdown()`**: Calls `closeSharedDatabase()` during graceful shutdown
-
-## [2.33.4] - 2026-01-21
-
-### Fixed
-
-- **Memory leak in SSE session reset** (Issue #542): Fixed memory leak when SSE sessions are recreated every 5 minutes
-  - Root cause: `resetSessionSSE()` only closed the transport but not the MCP server
-  - This left the SimpleCache cleanup timer (60-second interval) running indefinitely
-  - Database connections and cached data (~50-100MB per session) persisted in memory
-  - Fix: Added `server.close()` call before `transport.close()`, mirroring the existing cleanup pattern in `removeSession()`
-  - Impact: Prevents ~288 leaked server instances per day in long-running HTTP deployments
-
 ## [2.33.3] - 2026-01-21

+### Why Use undefined?
+- **Property removal vs. null**: Setting a property to \`undefined\` removes it completely from the node object, while \`null\` sets the property to a null value
 - **Validation constraints**: Some properties are mutually exclusive (e.g., \`continueOnFail\` and \`onError\`). Simply setting one without removing the other will fail validation
