# Release v1.7.4 - Critical Hotfix ## 🚨 Critical Bug Fix This hotfix release addresses a critical issue that prevented skills activation when using common version formats. ### Fixed - **Skills Activation Failure** (#935): Skills with versions like "1.1" or "2.0" were failing to activate due to overly strict semantic versioning validation. The system now accepts flexible version formats while maintaining backwards compatibility. ## Changes ### Version Validation Improvements - ✅ Now accepts flexible version formats: - Single number: `"1"` - Major.Minor: `"1.0"`, `"1.1"`, `"2.0"` - Full semver: `"1.0.0"`, `"2.1.3"` - With prerelease: `"1.0.0-beta"`, `"1.0-rc.1"` - With build metadata: `"1.0.0+build123"` ### New Features - **Version Normalization Utility**: Added `normalizeVersion()` function that: - Converts short versions to full semver format - Strips leading zeros for consistency (e.g., "01.02" → "1.2.0") - Preserves prerelease and build metadata ### Developer Experience - Improved error messages with clear format requirements and multiple examples - Added comprehensive test coverage (30 tests for version validation) - Enhanced documentation with inline explanations ## Impact - **Immediate Fix**: Skills with versions like "1.1" will now activate successfully - **Better UX**: LLMs and humans can use natural version formats - **Backwards Compatible**: All existing semver versions continue to work - **Consistency**: Version normalization ensures consistent comparisons ## Technical Details - Modified `BaseElement.ts` version validation regex to accept optional minor and patch versions - Added comprehensive tests in `BaseElement.test.ts` - Implemented leading zero normalization to prevent confusion ## Credits - Issue reported and investigated by @mickdarling - Fix implemented with assistance from Claude Code - Excellent review feedback from the community ## Upgrade Instructions ```bash npm update @dollhousemcp/mcp-server@1.7.4 ``` --- **Full Changelog**: https://github.com/DollhouseMCP/mcp-server/compare/v1.7.3...v1.7.4
