-## [0.1.6b15] - 2026-01-17
+## [Unreleased]
 
 ### Added
-- **Virtual Printer "Queue" mode** - New mode that archives files and adds them to the print queue:
-  - Three modes now available: Archive (immediate), Review (pending list), Queue (print queue)
-  - Queue mode creates unassigned queue items that can be assigned to a printer later
-  - Renamed old "Queue for Review" to "Review" to avoid confusion with print queue
-- **Unassigned queue items** - Print queue now supports items without an assigned printer:
-  - Queue items can be created without a printer (printer_id nullable)
-  - Queue page shows "Unassigned" filter option and highlights unassigned items in orange
-  - Edit modal allows assigning a printer to unassigned items
-  - Useful for virtual printer uploads where target printer is decided later
-- **Sidebar badge indicators** - Visual indicators on sidebar icons for pending items:
-  - Queue icon shows yellow badge with count of pending queue items
-  - Archive icon shows blue badge with count of pending uploads (virtual printer review items)
-  - Badges auto-update every 5 seconds and on window focus
+- **Fusion 360 design file attachments** - Attach F3D files to archives for complete design tracking:
+  - Upload F3D files via archive context menu ("Upload F3D" / "Replace F3D")
+  - Cyan badge on archive card indicates attached F3D file (next to source 3MF badge)
+  - Click badge to download, or use "Download F3D" in context menu
+  - F3D files included in backup/restore
+  - API tests for F3D endpoints
 
-### Changed
-- Virtual printer mode labels: "Immediate" → "Archive", "Queue for Review" → "Review"
-- Queue page printer filter now includes "Unassigned" option
-
-## [0.1.6b14] - 2026-01-17
-
-### Fixed
-- **Chamber temp showing on printers without sensor in multi-printer setups** - Fixed regression where A1/P1S chamber temperature would appear after adding a second printer:
-  - Root cause: REST API `/printers/{id}/status` endpoint wasn't filtering chamber temp by model
-  - WebSocket broadcasts filtered correctly, but initial REST fetch didn't
-  - Now both REST and WebSocket consistently filter chamber temp for P1P/P1S/A1/A1Mini
-  - Fixes [#82](https://github.com/maziggy/bambuddy/issues/82) (multi-printer regression)
-
-## [0.1.6b13] - 2026-01-16
-
-### Fixed
-- **Queue prints failing on A1 printers** - Fixed "MicroSD Card read/write exception error" when starting prints from queue:
-  - Root cause: Queue uploaded files to `/cache/` but print command referenced root `/`
-  - Queue now uploads to root directory like archive reprint does
-  - Added filename cleaning (handles `.gcode.3mf` double extensions)
-  - Added pre-delete of existing files to avoid FTP 553 errors
-  - Fixes [#86](https://github.com/maziggy/bambuddy/issues/86)
-
-## [0.1.6b12] - 2026-01-16
-
-### Added
-- **Project parts tracking** - Track individual parts/objects separately from print plates:
-  - New "Target Parts" field in project create/edit modal alongside "Target Plates"
-  - Separate progress bars for plates (print jobs) vs parts (objects printed)
-  - Parts count auto-detected from 3MF files when archiving prints
-  - Project cards show both plates and parts counts in footer stats
-  - Example: Voron build with 25 plates producing 150 parts total
-  - Closes [#85](https://github.com/maziggy/bambuddy/issues/85)
-- **Archive quantity auto-detection** - Automatically set parts count when archiving:
-  - Extracts printable object count from 3MF `slice_info.config`
-  - Respects skipped objects (not counted)
-  - Falls back to 1 if extraction fails
-- **Migration script for existing archives** - Update quantities on existing archives:
-  - Run `python scripts/update_archive_quantities.py` to update existing archives
-  - Use `--dry-run` flag to preview changes without applying them
-  - Parses 3MF files to extract correct object counts
-
-### Changed
-- Project stats now correctly distinguish between plates (archive count) and parts (sum of quantities)
-- Project list `completed_count` now represents parts printed, not print jobs
-- Progress calculations: plates use `archive_count/target_count`, parts use `completed_count/target_parts_count`

 ## [0.1.6b] - 2025-12-28
 
 ### Added
-- **Tasmota device discovery** - Automatically discover Tasmota smart plugs on your network. Click "Discover Tasmota Devices" in the Add Smart Plug modal to scan your local subnet. Supports devices with and without authentication.
-- **Switchbar for quick smart plug access** - New sidebar widget for controlling smart plugs without leaving the current page. Enable "Show in Switchbar" for any plug to add it to the quick access panel. Shows real-time status, power consumption, and on/off controls.
-- **Timelapse editor** - Edit timelapse videos with trim, speed adjustment (0.25x-4x), and music overlay. Uses FFmpeg for server-side processing with browser-based preview.
-- **AMS filament preview** - Reprint modal shows filament comparison between what the print requires and what's currently loaded in the AMS. Compares both type and color with visual indicators (green=match, yellow=color mismatch, orange=type mismatch). Includes Re-read button to refresh AMS status from printer, fuzzy color matching for similar colors, and shows AMS slot location for each matched filament.
-- **File type badge** - Archive cards now show GCODE (green) or SOURCE (orange) badge to indicate whether the file is a sliced print-ready file or source-only.
-- **Docker printer discovery** - Subnet scanning for discovering printers when running in Docker with `network_mode: host`. Automatically detects Docker environment and shows subnet input field in Add Printer dialog.
-- **Printer model mapping** - Discovery now shows friendly model names (X1C, H2D, P1S) instead of raw SSDP codes (BL-P001, O1D, C11).
-- **Discovery API tests** - Comprehensive test coverage for discovery endpoints.
-- **Project filament colors** - Project cards now display filament color swatches from assigned archives.
-- **BOM filter** - Hide completed BOM items with "Hide done" toggle on project detail page.
-- **Projects in backup/restore** - Projects, BOM items, and attachments now included in database backup/restore.

-- **Project card design** - Enhanced visual polish with gradients, shadows, and glow effects on hover.
-- **Project page layout** - Improved spacing and padding on project list and detail pages.
-- **Delete confirmations** - Replaced browser confirm dialogs with styled confirmation modals.
+- **Smart Plugs** - Tasmota device discovery and Switchbar quick access widget

 ### Fixed
-- **Notification module** - Fixed bug where notifications were sent even when printer was offline.
-- **Attachment uploads** - Fixed file attachments not persisting due to SQLAlchemy JSON column mutation detection.
-- **Camera stream stability** - Fixed stream stopping after a few minutes by increasing ffmpeg read timeout (10s→30s), adding buffer options, and implementing auto-reconnection with exponential backoff in the frontend.
+- Notifications sent when printer offline
+- Camera stream stopping with auto-reconnection
+- A1/P1 camera streaming with extended timeouts
+- Attachment uploads not persisting
+- Total print hours calculation
 
 ## [0.1.5] - 2025-12-19
 
-### Fixed

-- **Timelapse auto-download** - Complete rewrite with retry mechanism and multiple path support
-- **Timelapse detection for H2D** - H2D sends timelapse status in ipcam.timelapse field, not xcam.timelapse
-- **Reprint from archive** - Fixed bug where print button sent slicer source file instead of sliced gcode
-- **Import shadowing bugs** - Fixed ArchiveService import shadowing causing "cannot access local variable" error
-- **Timelapse race condition** - xcam data was parsed before print state was set
-
