+### Issue #42 Complete - Allow Spools Heavier Than Max
+
+Removed weight validation cap that prevented spools from exceeding their theoretical initial weight.
+
+**Backend:**
+- `spoolman/database/spool.py` - Removed `max(..., 0)` clamps from create/update; when remaining > initial, adjusts initial upward
+- `spoolman/api/v1/models.py` - Removed `max(..., 0)` from remaining_weight computation
+
+### Issue #43 Complete - Show Filament Fields on Spool View
+
+Display filament custom fields on the spool detail page.
+
+**Frontend:**
+- `client/src/pages/spools/show.tsx` - Added `filamentExtraFields` section after spool extra fields
+
+### Issue #25 Complete - Sort by Custom Fields & Remaining Weight
+
+**Backend:**
+- `spoolman/database/spool.py` - Added `extra.{key}` sort support via outerjoin on SpoolField table
+
+**Frontend:**
+- `client/src/pages/spools/list.tsx` - Added `sorter: true` to weight/length NumberColumns
+- `client/src/components/column.tsx` - Changed CustomFieldColumn to sortable with `dataId: extra.{key}`
+
+### Issue #35 Complete - Global Search Box
+
+**Backend:**
+- `spoolman/api/v1/spool.py` - Added `q` parameter to find endpoint
+- `spoolman/database/spool.py` - OR-based search across filament name, material, vendor name, location, lot_nr, comment
+
+**Frontend:**
+- `client/src/pages/spools/list.tsx` - Added `Input.Search` component, passes `q` via meta.queryParams
+
+### Issue #20 Complete - Gallery View for Spools
+
+Color grid view for spools with progress bars and material labels.
+
+**Frontend:**
+- `client/src/pages/spools/components/SpoolGallery.tsx` - Grid of color cards with progress bars
+- `client/src/pages/spools/list.tsx` - View mode toggle (table/gallery)
+
+### Issue #36 Complete - Spool-Level Overrides
+
+Per-spool color override with ColorPicker (price and initial_weight already existed).
+
+**Backend:**
+- `spoolman/database/models.py` - Added `color_hex` field to Spool model
+- `spoolman/api/v1/spool.py` - Added `color_hex` to create/update params
+- `migrations/versions/2025_01_22_0100-g7h8i9j0k1l2_add_spool_color_hex.py`
+
+**Frontend:**
+- `client/src/pages/spools/create.tsx`, `edit.tsx` - ColorPicker form field
+- All display locations updated to prefer `spool.color_hex` over `filament.color_hex`
+
+### Issue #39 Complete - Usage Statistics & Cost Tracking
+
+Added cost analytics endpoint and total spent / avg cost per kg stats.
+
+**Backend:**
+- `spoolman/api/v1/other.py` - Added `GET /analytics/cost` endpoint returning total_spent, avg_cost_per_kg, cost_by_material
+
+**Frontend:**
+- `client/src/pages/home/components/QuickStats.tsx` - Added "Total Spent" and "Avg Cost/kg" stat cards
+- `client/src/pages/home/components/UsageAnalytics.tsx` - Added cost per material in breakdown cards
+
+### Bug Fixes
+
+- **Filament Select Refresh**: Fixed race condition where form value was set before options re-rendered. Uses `pendingFilamentId` state + useEffect.
+- **Parse Temps from Comments**: Added regex-based temperature parser button on filament edit page.
+
 ## Known Issues / TODO
 
-### Parse Temperature from Comments
-Some filaments have temp info in comment field (e.g., "extrude 190-230 / bed 50-70") but not in the min/max fields. Could add a migration or button to parse and populate.
-
-### Filament Select Not Refreshing After Inline Creation
-When creating a filament via the inline modal on spool create page, the select dropdown doesn't immediately show the new filament with its name (shows ID instead).

 ### Issue #7 - 3dfilamentprofiles Integration REMOVED
 The 3dfilamentprofiles.com website has Vercel bot protection that blocks automated requests. Their GitHub repo (jklewa/filament-profiles-data) only provides sample data (~3 filaments). Since SpoolmanDB already has 6,957+ filaments from major brands, the 3dfp integration was removed rather than maintaining dead code.
