StudsUp — Version history

v9.1 Current July 25, 2026

Own mail server, real password reset, parts-image overhaul, and profile-blog fixes

✉️

Own mail server — StudsUp now runs its own Postfix server with DKIM signing for studsup.eu, relayed for delivery. Powers password resets and account emails New Backend

🔑

Real password reset — "Forgot password?" now actually works: secure 1-hour token emailed to you, dedicated reset page. Previously just showed a fake success message Fix

📧

Email verification on signup — new accounts receive a welcome/verification email; existing accounts are grandfathered in as verified New

🔔

Notification settings — new "Alerts" tab in profile settings: master email toggle, new-listing alert toggle, and a configurable check frequency (2/5/10/20/30/60 min) New

🖼️

Parts catalogue images fixed at the root cause — the LDraw fallback colour code used everywhere ('16') was a meta-colour that never renders; changed to '0' across the catalogue, collection, missing-parts checklist and homepage. Coverage on a broad sample jumped from ~19% to 84%+ Fix Backend

📄

Honest icons for unphotographable items — activity booklets, cards and manuals now show a document icon instead of a broken-looking placeholder; wire/cable parts show a plug icon when no real photo exists Improved

🔗

Printed/decorated part variants — BrickLink usually only photographs the plain mold, not every print; added a base-mold fallback so parts like printed minifig pieces and dragon wings find a real photo more often Fix

📑

Pagination bug fixed — Technic/Duplo filtering was happening client-side after the page was already fetched, occasionally producing "No parts found" on a valid page number. Moved server-side so totals and page counts are always accurate Fix Backend

↕️

Parts sort dropdown — was previously decorative only; now actually sorts by price, availability, sold quantity or element ID Fix

📸

Blog photo/video posts — Photo and Video post types can now actually attach a real upload; previously there was no file picker at all despite the option existing Fix

💾

Profile settings actually save — display name, bio, location, avatar photo/colour and password changes were previously cosmetic only (localStorage-only, no server call); all now persist for real Fix

📱

Mobile camera fix — scanning a set or identifying a brick now opens a single native camera/gallery picker instead of forcing the camera and sometimes double-capturing a photo Fix

v9.0 June 27, 2026

Color system overhaul — accurate colours, instant filter, multi-select

🎨

Color accuracy fix — GROUP BY rp.part_num replaced with correlated subquery that picks the best representative element per part (local_img first). Eliminated ~70% grey (#cccccc) colour swatches Fix Backend

⚡

Instant colour filter — clicking a colour in the sidebar now immediately filters parts without needing "Apply filters" button Fix

🎛️

Multi-colour filter — new color_ids query parameter accepts comma-separated IDs; selecting multiple colours now works New Backend

0️⃣

Black (color_id=0) fix — falsy zero was skipped by colour filter logic; now correctly filters 10,047 black parts Fix

🔍

Search page — removed both occurrences of dev uvicorn startup instructions shown to production users Fix

🧪

Full deployment check — automated 10-point test suite: API health, colour accuracy, Black/multi-colour filters, BL fields, search warning, part detail, builder, category images, instant filter Improved

v8.9 June 27, 2026

Parts catalogue — 12 categories, real LEGO images, BrickLink fallback

📦

12 clean categories — replaced 60+ raw Rebrickable categories with 12 BrickArchitect-inspired groups: Basic · Plates · Slopes · Round & Curved · SNOT · Panels & Windows · Minifig · Nature · Vehicle · Technic · Duplo · Other New

🧱

Category thumbnails — each category now shows a real 36px LEGO part photo instead of emoji. Images sourced from local element DB with BrickLink CDN fallback New

🖼️

4-source image waterfall — part images try: local DB → BrickLink colored (PN/{color_id}/{part_id}) → BrickLink no-color (PL/{part_id}) → Rebrickable LDraw render Improved

🔗

API fields — /api/catalog now returns bl_part_id, bl_color_id, part_name, color_css for BrickLink image URL construction Backend New

🗑️

Removed "Rebrickable catalogue" button from parts page header Fix

🔍

Part detail — dynamic loading — /pages/part-detail.html?part=6396802 now resolves correct part by element_id or bl_part_id instead of showing hardcoded Plate 2×4 demo Fix

v8.8 June 27, 2026

MOC Builder v9.4 — connection engine, stud-exact positioning, PDF generation

🔩

Connection engine — getConnectionY(partNum) returns correct LDraw Y offset per part type. 6157 wheel holder: Y=−8 (stug anti-stud at Y=8). All others: Y=0. Eliminates parts floating inside the plate New

📐

Stud-exact placement — 1762 go-cart parts placed on real stud positions derived from .dat geometry: steering at Z=−30, round bricks at Z=+30, holders at Z=±20 Y=−8, wheels at Y=−3 (holder −8 + wpin +5) Fix

📄

PDF hang fix — pre-renders all step screenshots before PDF generation; eliminated indefinite hang on tyre subfile loading Fix

🐛

Duplicate DOCTYPE fix — Python string replace was appending full file as text inside template literal; caused SyntaxError and blank builder page Fix

🎨

CHART_COLORS guard — shared.js redeclaration on repeated navigation caused builder JS to silently fail; wrapped in if(typeof…===undefined) guard Fix

🧪

POC 33/33 — all tests passing: core:16/16 · 1762:8/8 · db:9/9. Every run generates 2 PDFs (1762 go-cart + 60400 go-kart) Improved

🏗️

📱

Mobile fix — removed red placeholder square from index page card Fix

v8.6 June 25, 2026

Search Engine Phase 1 — FTS5 BM25 ranked search across all 78k parts

🔍

rb_parts_fts index — FTS5 trigram virtual table built over all 78,633 catalogue parts on startup Backend New

📊

BM25 ranking — parts catalogue search now ranks by relevance (exact part_num first, prefix second, BM25 score third) instead of plain LIKE scan Improved

⚡

Global search parts — /api/search now queries 78k rb_parts via FTS before falling back to LUGBULK parts table Improved

🗂️

/api/catalog/facets — new endpoint returning category counts for the active search query; powers live sidebar filter badges New

🔎
