## [0.1.6] - 2025-01-25

### Added
- **Dynamic Status Management System**
  - Per-project customizable status workflows (replacing hardcoded statuses)
  - New default statuses: `backlog`, `in_progress`, `on_hold`, `done` (removed `blocked`)
  - Project Settings modal with comprehensive status management:
    - Drag-and-drop status reordering
    - Add new custom statuses
    - Rename existing statuses (inline editing)
    - Delete unused statuses with validation
    - Task count display per status
    - Warning dialogs when attempting to delete statuses with tasks
  - Settings button (⚙️) in project header to access configuration
  - Status validation in backend CRUD operations
  - Database migration for `projects.statuses` JSON column

- **Enhanced Task Creation**
  - Status selector dropdown in TaskForm component
  - Select status when creating tasks (no longer defaults to "backlog" only)
  - Works across Tree View and Kanban View
  - Defaults to current column status in Kanban View
  - Defaults to "backlog" in Tree View

- **Subtask Creation in Kanban View**
  - "+" button on task cards to add subtasks directly in Kanban
  - Button appears on hover next to task menu
  - Opens TaskForm with status defaulted to current column
  - Automatically expands parent card after creating subtask
  - Full parity with Tree View subtask functionality

### Changed
- Removed hardcoded status enums from backend (`TaskStatus` enum removed)
- Task status field changed from Enum to String in database
- All status references now dynamic (backend, frontend, Kanban UI)
- Status formatting helpers added for consistent display
- Status colors now pattern-matched based on status names
- Existing tasks migrated from uppercase enum format to lowercase

### Backend Changes
- `models.py`: Added `DEFAULT_STATUSES` constant, `statuses` JSON column to Project, changed Task.status to String
- `schemas.py`: Changed status from TaskStatus enum to str, added statuses to Project schemas
- `crud.py`: Added status validation in create_task, update_task, get_tasks_by_status
- `main.py`: Added status validation to endpoints and JSON import

### Frontend Changes
- `ProjectSettings.jsx`: New component for managing project status workflows
- `TaskForm.jsx`: Added status selector with dynamic status list
- `KanbanView.jsx`: Dynamic status columns, subtask creation, removed hardcoded STATUSES
- `TaskMenu.jsx`: Dynamic status dropdown using projectStatuses prop
- `TreeView.jsx`: Dynamic status helpers, passes statuses to forms
- `ProjectView.jsx`: Integrated ProjectSettings modal with gear icon button

### Fixed
- Database schema migration for projects.statuses column
- Task status migration from uppercase (BACKLOG, IN_PROGRESS, DONE) to lowercase format
- 51 existing tasks successfully migrated to new status format

### Technical Details
- New database column: `projects.statuses` (JSON, default: ["backlog", "in_progress", "on_hold", "done"])
- Status validation at multiple layers (CRUD, API endpoints, frontend)
- Helper functions for status formatting and color coding
- Prop drilling of projectStatuses through component hierarchy

## [0.1.5] - 2025-01-XX

### Added
- **Nested Kanban View** - Major feature implementation
  - Parent tasks now appear in each column where they have subtasks
  - Parent cards show "X of Y subtasks in this column" indicator
  - Parent cards are expandable/collapsible to show children in that column
  - Parent cards have distinct visual styling (thicker orange border, bold text)
  - Only leaf tasks (tasks with no children) are draggable
  - Parent cards automatically appear in multiple columns as children move
- Helper functions for nested Kanban logic:
  - `getDescendantsInStatus()` - Get all descendant tasks in a specific status
  - `hasDescendantsInStatus()` - Check if parent has any descendants in a status

### Changed
- Kanban board now labeled "Kanban Board (Nested View)"
- Parent task cards cannot be dragged (only leaf tasks)
- Column task counts now include parent cards
- Improved visual hierarchy with parent/child distinction

### Improved
- Better visualization of task distribution across statuses
- Easier to see project structure while maintaining status-based organization
- Parent tasks provide context for subtasks in each column

## [0.1.4] - 2025-01-XX

### Added
- Strikethrough styling for time estimates when tasks are marked as "done"
- Auto-complete parent tasks when all child tasks are marked as "done"
  - Works recursively up the task hierarchy
  - Parents automatically transition to "done" status when all children complete

### Changed
- Time estimates on completed tasks now display with strikethrough decoration
- Parent task status automatically updates based on children completion state

## [0.1.3] - 2025-01-XX

### Added
- Enhanced task creation forms with metadata fields
  - Title field (required)
  - Tags field (comma-separated input)
  - Time estimate fields (hours and minutes)
  - Flag color selector with 8 color options
- TaskForm component for consistent task creation across views
- Status change dropdown in TaskMenu (no longer requires Kanban view)
- Leaf-based time calculation system
  - Parent tasks show sum of descendant leaf task estimates
  - Prevents double-counting when both parents and children have estimates
  - Excludes "done" tasks from time calculations
- Time format changed from decimal hours to hours + minutes (e.g., "1h 30m" instead of "1.5h")
- CHANGELOG.md and README.md documentation

### Changed
- Task creation now includes all metadata fields upfront
- Time estimates display remaining work (excludes completed tasks)
- Time input uses separate hours/minutes fields instead of single minutes field
- Parent task estimates calculated from leaf descendants only

### Fixed
- Time calculation now accurately represents remaining work
- Time format more human-readable with hours and minutes

## [0.1.2] - 2025-01-XX

### Added
- Metadata fields for tasks:
  - `estimated_minutes` (Integer) - Time estimate stored in minutes
  - `tags` (JSON Array) - Categorization tags

- Backend search endpoint `/api/search` with project filtering

### Changed

- Enhanced visual design with metadata badges

## [0.1.1] - 2025-01-XX

### Fixed
- Tree view indentation now scales properly with nesting depth
  - Changed from fixed `ml-6` to calculated `marginLeft: ${level * 1.5}rem`
  - Each nesting level adds 1.5rem (24px) of indentation
- Kanban view subtask handling
  - All tasks (including subtasks) now appear as individual draggable cards
  - Subtasks show parent context: "↳ subtask of: [parent name]"
  - Removed nested subtask list display
