v1.6.2 release notes

Release Date: December 16, 2025 Type: Patch Release (Bug Fixes) Status: Completed

Overview

Version 1.6.2 addresses immediate technical debt items identified in the v1.6.1 tech debt analysis, focusing on code quality improvements and configuration correctness. This release fixes all ESLint errors in test files, corrects the ENABLE_WORKERS default configuration to match implementation status, and updates all related documentation.

What’s Fixed

ESLint Error Resolution (12 fixes)

All ESLint errors in test files have been resolved, improving code quality and maintainability:

Import Cleanup

errors.test.mjs: Removed unused beforeEach import
mcp-server.test.mjs: Removed unused vi import
recipe-manager.test.mjs: Removed unused vi import
recipe-validator.test.mjs: Removed unused beforeEach import
streaming.test.mjs: Removed unused beforeEach import

Code Quality Fixes

logger.test.mjs: Fixed duplicate key operation in cache test object (changed to toolName)
recipe-storage.test.mjs: Removed unused variable backupExists
recipe-validator.test.mjs:
- Fixed camelCase violations: drop_control_chars → dropControlChars
- Fixed dot notation issue: recipes["id0"] → recipes.id0
streaming.test.mjs: Added eslint-disable-next-line for intentionally unused loop variables

Verification

npm run lint
# ✓ All ESLint checks pass (0 errors, 0 warnings)

Configuration Default Correction

Fixed misleading default for ENABLE_WORKERS environment variable:

Changes

Previous: ENABLE_WORKERS = true (default enabled)
Current: ENABLE_WORKERS = false (default disabled)
Reason: Worker thread implementation is not yet complete

Files Updated

src/node/mcp-server.mjs:

// Before
const ENABLE_WORKERS = process.env.CYBERCHEF_ENABLE_WORKERS !== "false";

// After
const ENABLE_WORKERS = process.env.CYBERCHEF_ENABLE_WORKERS === "true";

README.md:
- Updated configuration options section
- Changed default value from true to false
- Added clarification: “disabled by default, not yet implemented”
docs/guides/user_guide.md:
- Updated environment variables table
- Changed default value from true to false
- Updated description: “not yet implemented”

Version Updates

All version references updated to v1.6.2:

Files Updated

package.json: mcpVersion field
src/node/mcp-server.mjs: VERSION constant
tests/mcp/mcp-server.test.mjs: Version test expectation
README.md: Download URLs and version references
CHANGELOG.md: New v1.6.2 section

Testing

Test Results

All tests continue to pass with improved code quality:

npm run test:mcp
# Test Files  9 passed (9)
# Tests       311 passed (311)
# Duration    8.73s

Coverage

Coverage metrics maintained at v1.6.1 levels:

Lines: 78.93%
Statements: 78.7%
Functions: 89.33%
Branches: 74.68%

Migration Guide

For Users

No action required - this is a patch release with backward-compatible fixes.

For Developers

If you have ENABLE_WORKERS explicitly set in your environment:

Previous Behavior

# Workers enabled by default, disable with:
export CYBERCHEF_ENABLE_WORKERS=false

New Behavior

# Workers disabled by default, enable with:
export CYBERCHEF_ENABLE_WORKERS=true

Note: Worker thread functionality is not yet implemented, so this change only affects the default value. The feature has no functional impact in either configuration.
