Changelog

v2.1.3 Latest

Buying a license, done in one place

• One-click purchase inside the app: click "Open Purchase Page" on the Account page — your Device ID is attached automatically, pay by scanning the WeChat QR code, and your key is issued instantly. No ID copying, no waiting for a human — the whole flow takes under a minute
• Key recovery made simple: after a reinstall, open the purchase page from the app and enter your Device ID to get your key back
• The official purchase page only opens from inside the app — never pay through "purchase links" sent in private messages

v2.1.2

Faster

• Compression up to 8× faster — a 12 MB model that took nearly 6 seconds now finishes in under 1 second
• Texture optimization 5× faster — multi-texture models drop from 6+ seconds to about 1 second
• KTX2 conversion 13× faster — per-texture encoding falls from 6.6s to 0.5s, so batches no longer keep you waiting
• Batch compression now uses all your CPU cores — over 2× faster on a 16-core machine

New: Announcements

• New releases and important updates pop up right in the app
• Click "Got it" and it never pops up again

Polished

• Numbers and file names render crisply — no more inconsistent fonts
• Unified colors and rounding across the app
• Keyboard focus is easy to spot; honors your system "reduce motion" setting

Fixed

• The "Learn more" link in the engine fallback notification no longer 404s

v2.1.1

• Fixed: the JSON editor area on the Data Tagging page rendered broken in the installed build (no height, no scrolling)
• Fixed: some OBJ models failed to convert
• Fixed: missing Start-menu and desktop icons after installation

v2.1.0

Free mode: free forever, no time limit

• The 6-hour trial is gone — the free tier is available forever: up to 20 MB per file (5 MB textures), batches of 5
• 3D Viewer, screenshots, screen recording and operation history are free and unlimited for everyone
• Licensed: 500 MB per file and unlimited batch size

New: Data Tagging

• Attach business info to model nodes (equipment IDs, floors, SKUs, sensor IDs…) — readable by your frontend out of the box
• Pick nodes from the tree or click them in the 3D viewport — you never lose track
• One-click JSON export / import so your team can reuse the same tags
• Stale tags left behind by deleted nodes are cleaned up automatically

3D Viewer enhancements

• Section clipping: cut a model open to inspect its internals, with three axes and direction invert
• Animation preview: play animations embedded in the model at 0.1x–3x speed
• Dark and metallic materials stay readable without extra lights; floor and lighting are fully adjustable
• Time-of-day lighting: simulate 24 hours of light for showcase recordings

Linux and macOS support

• New Linux (deb / rpm) and macOS (dmg / drag-to-install) builds
• In-app notification when a new version ships — never miss an update
• Fixed inconsistent oversized-texture warnings and import dialogs

v2.0.1

Full speed, even offline

• Compression and transcoding no longer depend on any external website — faster and more reliable loads on intranets and offline machines

v2.0.0

New: one-click scenario presets

• Four built-in presets — Web showcase, mobile, industrial visualization, e-commerce — pick a scenario and get optimal settings
• After import, Zipoly automatically recommends the best engine for your model

Two engines, one click apart

• Draco for broad compatibility, Meshopt for higher compression; if Meshopt is unavailable Zipoly falls back to Draco automatically — your work never stops

Meshopt engine enhancements

• Mesh simplification: further reduce polygons so low-end devices stay smooth
• GPU instancing and node merging: even smaller files for repeated objects
• Staged progress display so you always know where the compression is

KTX2 texture enhancements

• New UASTC high-quality mode: near-lossless for detail textures like normals
• Ten quality levels to balance size against fidelity yourself

Other

• Installer size reduced by ~60% — faster to download and install
• Fixed batch parameters not applying after switching engines

---

v1.0.2 Stable

New: Meshopt compression engine

• A second engine with better compression ratio than Draco — one click to switch, automatic fallback when unavailable

New: KTX2 texture compression

• GPU-native texture format — smaller files, faster loading
• Optional Mipmap chain toggle saves another ~33%

New: Texture Optimization tab

• Compress and resize loose PNG / JPG / WebP files, with KTX2 conversion

New: model health check

• Automatic scan on import flags duplicate vertices, oversized textures, missing normals and more

---

v1.0.1

• New 24-hour time-of-day lighting and custom lights for richer showcases
• New screenshot (PNG) and video recording (WebM) export
• Batch compression now supports pause / resume / cancel
• New advanced quantization panel (Draco only) for fine-grained control
• Better handling of Chinese and special-character paths
• Fixed errors when re-compressing an already compressed file

---

v1.0.0

• First release
• Draco compression for glTF/GLB (levels 1–10)
• Single-file and batch modes
• Format conversion (OBJ / FBX / STL / DAE / PLY → GLB / glTF)
• Texture optimization (auto downsampling + JPEG recompression)
• Operation history (with parameter reuse)
• Compression result comparison dialog
• Built-in Three.js 3D viewer
• Offline licensing (hardware-ID bound)

---

Zipoly Server

The server edition (private deployment for enterprises) versions independently from the desktop app. Release history below.

v2.1.0 (Server)

Conversion engine rebuilt (assimp 5.4.3)

• assimp replaces the previous implementation; input: glb / gltf / fbx / obj / stl / dae / ply / vrm; output: glb / gltf / obj / stl(stlb) / ply(plyb) / dae
• Fixed GLB→OBJ white-model issue and GLB degenerate faces

Texture optimization & KTX2

• New texture optimization (single-image PNG / JPG / WebP processing)
• KTX2 encoding (basisu 1.16): ETC1S / UASTC modes (both the compression path and single-image texture optimization), encode performance improved 45s → 15s
• Meshopt UASTC mode supports texture quality levels (1–10 mapped to basisu -q)

Batch tasks deeply optimized

• Batch ZIP downloads now built in memory with Stored compression, eliminating temp-file races — 25s → 2s
• Download loading feedback, auto-completed compression params, download button appears when done

SSE real-time push

• Task / batch status pushed in real time, replacing polling; automatic fallback to polling on disconnect
• Backend supports direct CORS connections, fixing long-lived connection truncation through the Vite proxy

Configuration system

• Config page truly reads/writes config.yaml (with BOM compatibility)
• Data retention extended from 24h to 168h (7 days)
• Completed system settings / service restart endpoints

Admin UI

• Dashboard visual redesign, data fixes, hour-aligned chart axes, adaptive card heights
• Task management adds GLB model preview (Three.js + Draco WASM local decoding)
• Batch task / task list UI deep optimizations

Licensing

• Verification switched to Ed25519 asymmetric signatures (same public key as license-server); activation state AES-256-GCM encrypted
• Server-side license tiers: Free / Pro / Enterprise (reported via capabilities endpoint)

Docker delivery

• Image tag: zipoly-server:2.1.0 (latest synced); release bundle = image tar + docker-compose.yml + Dockerfile + docker/ (config.yaml, entrypoint.sh, nginx.conf)
• Dockerfile uses BuildKit build cache (npm / cargo registry / target mounts) for incremental rebuilds
• Fixed cache mounts dropping binaries from the image layer (artifacts copied across stages via /out)
• Data directory unified to /app/zipoly-data inside the container (uploads / results / SQLite); compose volume mounts aligned
• Fixed API Key missing causing the container to keep Restarting (compose injects dev-api-key-123 by default; production must replace it with a strong key)

Fixes

• Task list query missing owner_key_id field returned empty arrays
• Task filenames lost after restart; task file residue cleanup
• SSE global watch duplicate registration, fallback polling false triggers, useEventSource init timing
• updateLicense request body field aligned with the backend (license_key)

v1.0.0 (Server)

• Server edition first release
• Desktop compression capabilities wrapped as a RESTful HTTP API (Draco / Meshopt compression, format conversion, texture optimization, model repair, health check, batch processing)
• Single-container Docker deployment (Rust/Axum backend + nginx reverse proxy) with a built-in web admin console
• API Key auth, rate limiting, input validation and other security measures
• Trial mode + License Key activation
