+# Changelog
+
+All notable changes to TESSERACT will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [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
+  - `flag_color` (String) - Priority flag with 7 color options
+- TaskMenu component with three-dot dropdown
+  - Edit time estimates
+  - Edit tags (comma-separated)
+  - Set flag colors
+  - Edit task title
+  - Delete tasks
+- SearchBar component in header
+  - Real-time search with 300ms debounce
+  - Optional project filtering
+  - Click results to navigate to project
+  - Displays metadata in results
+- Time and tag display in TreeView and KanbanView
+- Flag color indicators on tasks
+- Backend search endpoint `/api/search` with project filtering
+
+### Changed
+- TreeView and KanbanView now display task metadata
+- 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
+
+### Changed
+- Improved visual hierarchy in tree view
+- Better subtask representation in Kanban board
+
+## [0.1.0] - 2025-01-XX
+
+### Added
+- Initial MVP release
+- Core Features:
+  - Arbitrary-depth nested task hierarchies
+  - Two view modes: Tree View and Kanban Board
+  - Self-hosted architecture with Docker deployment
+  - JSON import for LLM-generated task trees
+- Technology Stack:
+  - Backend: Python FastAPI with SQLAlchemy ORM
+  - Database: SQLite with self-referencing Task model
+  - Frontend: React + Tailwind CSS
+  - Deployment: Docker with nginx reverse proxy
+- Project Management:
+  - Create/read/update/delete projects
+  - Project-specific task trees
+- Task Management:
+  - Create tasks with title, description, status
+  - Four status types: Backlog, In Progress, Blocked, Done
+  - Hierarchical task nesting (task → subtask → sub-subtask → ...)
+  - Add subtasks to any task
+  - Delete tasks (cascading to all subtasks)
+- Tree View:
+  - Collapsible hierarchical display
+  - Expand/collapse subtasks
+  - Visual nesting indentation
+  - Inline editing
+  - Status display
+- Kanban Board:
+  - Four columns: Backlog, In Progress, Blocked, Done
+  - Drag-and-drop to change status
+  - All tasks shown as cards (including subtasks)
+- JSON Import:
+  - Bulk import task trees from JSON files
+  - Supports arbitrary nesting depth
+  - Example import file included
+- UI/UX:
+  - Dark cyberpunk theme
+  - Orange (#ff6b35) accent color
+  - Responsive design
+  - Real-time updates
+
+### Technical Details
+- Backend API endpoints:
+  - `/api/projects` - Project CRUD
+  - `/api/tasks` - Task CRUD
+  - `/api/projects/{id}/tree` - Hierarchical task tree
+  - `/api/projects/{id}/tasks` - Flat task list
+  - `/api/projects/{id}/import` - JSON import
+- Database Schema:
+  - `projects` table with id, name, description
+  - `tasks` table with self-referencing `parent_task_id`
+- Frontend Routing:
+  - `/` - Project list
+  - `/project/:id` - Project view with Tree/Kanban toggle
+- Docker Setup:
+  - Multi-stage builds for optimization
+  - Nginx reverse proxy configuration
+  - Named volumes for database persistence
+  - Development and production configurations
