## [1.9.20] - 2026-01-19

### ✨ Added

- **Update User Story Status**
  - New `updateUserStoryStatus` tool
  - Allows updating the status of a user story (e.g., "New" -> "In Progress")
  - Validates status against project's workflow
  - Addresses feature gap compared to Issues

## [1.9.15] - 2025-01-XX

### 🎯 Major Features

#### Complete Pagination Support
- **Fixed Issue #2**: [List User Stories does not bring all the user stories](https://github.com/greddy7574/taigaMcpServer/issues/2)
- Added complete pagination support for ALL list operations
- No more missing data - all pages are automatically fetched

### ✨ Added

- **Get User Story by ID** - Completes Issue #2 implementation
  - New `getUserStory(userStoryId)` method in `taigaService.js`
  - New `getUserStory` MCP tool for querying individual user stories
  - Comprehensive user story details including Epic, Sprint, Points, Tasks
  - Test suite: `test/getUserStoryTest.js` (5 validations, 100% pass)

- **Pagination Module** (`src/pagination.js`)
  - New `fetchAllPaginated()` utility function for universal pagination handling
  - Supports multiple Taiga API response formats (paginated and non-paginated)
  - Intelligent detection of pagination metadata
  - Safety limit (max 100 pages) to prevent infinite loops
  - Graceful error handling with partial results

- **Comprehensive Pagination Tests** (`test/paginationTest.js`)
  - 10 test cases covering all pagination scenarios
  - Mock tests for utility functions
  - Real API tests for all list operations
  - 100% test success rate

- **Documentation**
  - New `docs/PAGINATION.md` with complete pagination guide
  - Architecture explanation and best practices
  - Performance considerations and optimization tips

### 🔄 Changed

All list methods in `TaigaService` now support full pagination:

- `listProjects()` - Returns ALL user projects across all pages
- `listUserStories(projectId)` - Returns ALL user stories (not just first page)
- `listIssues(projectId)` - Returns ALL issues across pagination
- `listMilestones(projectId)` - Returns ALL sprints/milestones
- `getIssuesByMilestone(projectId, milestoneId)` - Returns ALL issues in a sprint
- `listEpics(projectId)` - Returns ALL epics
- `listWikiPages(projectId)` - Returns ALL wiki pages

### 🛠️ Technical Improvements

- **Eliminated Circular Dependencies**
  - Separated pagination logic into dedicated module
  - Clean import structure: `taigaService.js` → `pagination.js` (no circular refs)

- **Backward Compatibility**
  - All existing MCP tool calls work without any changes
  - API interfaces remain unchanged
  - Only difference: now returns complete data sets

### 📊 Impact

**Before (v1.9.14 and earlier):**
- Projects with >30 user stories: Only first 30 visible to LLM
- Projects with >30 issues: Only first 30 accessible
- Large projects: Incomplete data caused incorrect analysis

**After (v1.9.15):**
- **100% data coverage** for projects with <3000 items (100 pages × 30 items/page)
- Automatic handling of all pagination scenarios
- LLM has access to complete project state

### 🧪 Testing

**New Test Suite:**
```bash
node test/paginationTest.js
```

**Results:**
- Total Tests: 10
- Passed: 10 (100%)
- Failed: 0

**Coverage:**
- Utility functions (mock data)
- Real API calls (all list operations)
- Edge cases (max page limit, partial failures)
