+## [2.44.1] - 2026-04-01
+
+### Security
+
+- **Bump axios** from `^1.11.0` to `^1.14.0` to patch known vulnerability
+- **Bump nodemon** from `^3.1.10` to `^3.1.14` to patch transitive dependency vulnerabilities
+
+### Changed
+
+- **Upgrade GitHub Actions** to latest versions across all CI/CD workflows (docker, release, test, update-n8n-deps) — contributed by @salmanmkc in #663
+
+Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en
+
+## [2.44.0] - 2026-04-01
+
+### Added
+
+- **Multi-step workflow generation flow**: `n8n_generate_workflow` now supports a three-step flow where AI agents act as quality gates — get proposals, review, then deploy. New parameters: `deploy_id` (deploy a specific proposal), `confirm_deploy` (deploy a previously generated preview).
+
+- **`GenerateWorkflowProposal` type**: New exported type for workflow proposals with `id`, `name`, `description`, `flow_summary`, and `credentials_needed` fields.
+
+- **`status` field on `GenerateWorkflowResult`**: Indicates the current phase — `proposals`, `preview`, `deployed`, or `error`.
+
+### Changed
+
+- **Tool description updated**: `n8n_generate_workflow` description now explains the multi-step flow instead of auto-deploy behavior.
+
+- **Tool documentation updated**: Essentials and full docs reflect the three-step flow with examples for each step.
+
+Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en
+
+## [2.43.0] - 2026-03-31
+
+### Added
+
+- **`n8n_generate_workflow` tool**: New MCP tool that enables AI-powered workflow generation from natural language descriptions. Available on the hosted service with handler delegation pattern for extensibility.
+
+- **Handler injection API**: `EngineOptions.generateWorkflowHandler` allows hosting environments to provide custom workflow generation backends. Handler receives helpers for `createWorkflow`, `validateWorkflow`, `autofixWorkflow`, and `getWorkflow`.
+
+- **Tool documentation**: Full essentials and deep documentation for `n8n_generate_workflow` via `tools_documentation`.
+
+### Fixed
+
+- **Tools documentation count**: Corrected n8n API tools count and added missing `n8n_manage_datatable` entry to tools overview.

+
+## [2.42.3] - 2026-03-30
+
+### Improved
+
+- **Patterns response trimmed for token efficiency** (Issue #683): Task-specific patterns response reduced ~64% — dropped redundant `displayName`, shortened field names (`frequency` → `freq`), capped chains at 5, and shortened chain node types to last segment.
+
+- **`patterns` mode added to `tools_documentation`**: Was missing from both essentials and full docs. AI agents can now discover patterns mode through the standard documentation flow.
+
+- **`includeOperations` omission behavior documented**: Added note that trigger nodes and freeform nodes (Code, HTTP Request) omit the `operationsTree` field.
+
+- **`search_nodes` examples trimmed**: Reduced from 11 to 6 examples in full docs, removing near-duplicates.
+
+Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en
+
+## [2.42.2] - 2026-03-30
+
+### Fixed
+
+- **`workflow-patterns.json` missing from npm package** (Issue #681): Added `data/workflow-patterns.json` to the `files` array in `package.json` so the patterns file is included in the published npm package and works out of the box without manual generation.
+
+Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en
+
+## [2.42.1] - 2026-03-30
+
+### Fixed
+
+- **Community nodes missing from database after rebuild**: Restored 584 community nodes from the n8n 2.13.3 snapshot and re-extracted operations with resource grouping from `properties_schema`. 366 community nodes now have proper resource-grouped operations.
+
+- **Community node service missing resource extraction**: `extractOperations()` in `community-node-service.ts` was not extracting `resource` from `displayOptions.show.resource`, same issue that was fixed in `property-extractor.ts` in v2.42.0.
+
+Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en
+
+## [2.42.0] - 2026-03-30
+
+### Added
+
+- **`includeOperations` flag for search_nodes**: Opt-in parameter that returns a resource/operation tree per search result, grouped by resource (e.g., Slack returns 7 resources with 44 operations). Saves a mandatory `get_node` round-trip when building workflows. Adds ~100-300 tokens per result.
+
+- **`searchMode: "patterns"` for search_templates**: New lightweight mode that serves workflow pattern summaries mined from 2,700+ templates. Returns common node combinations, connection chains, and frequency data per task category (10 categories: ai_automation, webhook_processing, scheduling, etc.). Use `task` parameter for category-specific patterns or omit for overview.
+
+- **Workflow pattern mining script** (`npm run mine:patterns`): Extracts node frequency, co-occurrence, and connection topology from the template database. Two-pass pipeline: Pass 1 analyzes `nodes_used` metadata (no decompression), Pass 2 decompresses workflows for connection analysis. Produces `data/workflow-patterns.json` with 554 node types, 3,201 edges, and 5,246 chains.
+
+### Fixed
+
+- **Operations extraction now includes resource grouping**: The property extractor was using `find()` to get only the first `operation` property, but n8n nodes have multiple operation properties each mapped to a different resource via `displayOptions.show.resource`. Changed to `filter()` to capture all operation properties. Slack went from 17 flat operations to 44 operations across 7 named resources.
+
+- **FTS-to-LIKE fallback dropped search options**: When the FTS5 search fell back to LIKE-based search (e.g., for "http request"), the `options` object (including `includeOperations`, `includeExamples`, `source`) was silently lost. Now correctly passed through.
+
+Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en
+
+## [2.41.4] - 2026-03-30
+
+### Fixed
+
+- **`validate_workflow` misses `conditions.options` check for If/Switch nodes** (Issue #675): Added version-conditional validation — If v2.2+ and Switch v3.2+ now require `conditions.options` metadata, If v2.0-2.1 validates operator structures, and v1.x is left unchecked. Previously only caught by `n8n_create_workflow` pre-flight but not by offline `validate_workflow`.
+
+- **False positive "Set node has no fields configured" for Set v3+** (Issue #676): The `validateSet` checker now recognizes `config.assignments.assignments` (v3+ schema) in addition to `config.values` (v1/v2 schema). Updated suggestion text to match current UI terminology.
+
+- **Expression validator does not detect unwrapped n8n expressions** (Issue #677): Added heuristic pre-pass that detects bare `$json`, `$node`, `$input`, `$execution`, `$workflow`, `$prevNode`, `$env`, `$now`, `$today`, `$itemIndex`, and `$runIndex` references missing `={{ }}` wrappers. Uses anchored patterns to avoid false positives. Emits warnings, not errors.
+
+Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en
+
+## [2.41.3] - 2026-03-27
+
+### Fixed
+
+- **Session timeout default too low** (Issue #626): Raised `SESSION_TIMEOUT_MINUTES` default from 5 to 30 minutes. The 5-minute default caused sessions to expire mid-operation during complex multi-step workflows (validate → get structure → patch → validate), forcing users to retry. Configurable via environment variable.
+
+- **Operations array received as string from VS Code** (Issue #600): Added `z.preprocess` JSON string parsing to the `operations` parameter in `n8n_update_partial_workflow`. The VS Code MCP extension serializes arrays as JSON strings — the Zod schema now transparently parses them before validation.
+
+- **`undefined` values rejected in MCP tool calls from VS Code** (Issue #611): Strip explicit `undefined` values from tool arguments before Zod validation. VS Code sends `undefined` as a value which Zod's `.optional()` rejects (it expects the field to be missing, not present-but-undefined).
+
+Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en
+
+## [2.41.2] - 2026-03-27
+
+### Fixed
+
+- **MCP initialization floods Claude Desktop with JSON parse errors** (Issues #628, #627, #567): Intercept `process.stdout.write` in stdio mode to redirect non-JSON-RPC output to stderr. Console method suppression alone was insufficient — native modules (better-sqlite3), n8n packages, and third-party code can call `process.stdout.write()` directly, corrupting the JSON-RPC stream. Only writes containing valid JSON-RPC messages (`{"jsonrpc":...}`) are now allowed through stdout; everything else is redirected to stderr. This fixes the flood of "Unexpected token is not valid JSON" warnings on every new chat in Claude Desktop, including leaked `refCount`, `dbPath`, `clientVersion`, `protocolVersion`, and other debug strings.
