feat: implement transferWorkflow operation in n8n_update_partial_workflow (#644) (#649)

Add transferWorkflow diff operation to move workflows between n8n projects:
- TransferWorkflowOperation type with destinationProjectId field
- WorkflowDiffEngine validates and tracks transfer intent
- Handler calls PUT /workflows/{id}/transfer after update
- N8nApiClient.transferWorkflow() method
- Zod schema validates destinationProjectId is non-empty
- Tool description and documentation updated
- inferIntentFromOperations case for transfer

Also fixes two pre-existing bugs found during review:
- continueOnError path now properly extracts/propagates activation flags
- Debug log in updateConnectionReferences shows correct old name

Based on work by @djakielski in PR #645.

 ## [Unreleased]
 
+## [2.38.0] - 2026-03-20
+
+### Added
+
+- **`transferWorkflow` diff operation** (Issue #644): Move workflows between projects via `n8n_update_partial_workflow`
+  - 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

+## [2.37.4] - 2026-03-18
+
+### Changed
+
+- **Updated n8n dependencies**: n8n 2.11.4 → 2.12.3, n8n-core 2.11.1 → 2.12.0, n8n-workflow 2.11.1 → 2.12.0, @n8n/n8n-nodes-langchain 2.11.2 → 2.12.0
+- **Rebuilt node database**: 1,239 nodes (809 from n8n-nodes-base and @n8n/n8n-nodes-langchain, 430 community)
+
+Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en
+
+## [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)

+
+## [2.37.2] - 2026-03-15
+
+### Fixed
+
+- **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

-## Removing Properties with undefined
+## Removing Properties with null
 
-To remove a property from a node, set its value to \`undefined\` in the updates object. This is essential when migrating from deprecated properties or cleaning up optional configuration fields.
+To remove a property from a node, set its value to \`null\` in the updates object. This is essential when migrating from deprecated properties or cleaning up optional configuration fields.
 
-### Why Use undefined?
+### Why Use null?
-- **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
+- **Property removal**: Setting a property to \`null\` removes it completely from the node object
 - **Validation constraints**: Some properties are mutually exclusive (e.g., \`continueOnFail\` and \`onError\`). Simply setting one without removing the other will fail validation
 - **Deprecated property migration**: When n8n deprecates properties, you must remove the old property before the new one will work

+## Removing Properties with null
 
-To remove a property from a node, set its value to \`undefined\` in the updates object. This is essential when migrating from deprecated properties or cleaning up optional configuration fields.
+To remove a property from a node, set its value to \`null\` in the updates object. This is essential when migrating from deprecated properties or cleaning up optional configuration fields.
 
-### Why Use undefined?
+### Why Use null?
-- **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
+- **Property removal**: Setting a property to \`null\` removes it completely from the node object
 - **Validation constraints**: Some properties are mutually exclusive (e.g., \`continueOnFail\` and \`onError\`). Simply setting one without removing the other will fail validation
 - **Deprecated property migration**: When n8n deprecates properties, you must remove the old property before the new one will work
