# Changelog {#changelog}

## v2.0.0 {#v2-0-0}

SnapOtter 2.0 turns the image toolkit into a full file-manipulation suite: 200+ tools across five modalities (Image, Video, Audio, PDF, and Files), rebuilt on Postgres 17 and a Redis-backed job queue, with a one-command `docker run`. This is a major release; read Breaking changes before upgrading from 1.x.

### New features {#new-features}

- **Four new tool modalities**: Video, Audio, PDF, and Files join Image, taking the catalog to 200+ tools.
- **Durable background jobs**: A Redis-backed queue (BullMQ) runs every tool as a tracked job with live SSE progress.
- **All-in-one single-container mode**: One `docker run` boots a complete instance with embedded Postgres and Redis.
- **On-demand AI bundles**: Background removal, OCR, transcription, upscaling, face detection and enhancement, object eraser, colorize, and photo restoration install from the UI. GPU acceleration is detected per framework.
- **Sign PDF**: Draw, type, or upload a signature and place it on a PDF in the browser.
- **Automate**: A visual pipeline builder that chains tools, with nine prebuilt templates.
- **83 one-click conversion presets**: Dedicated JPG-to-PNG, MP4-to-GIF, and similar converters with fuzzy search.
- **Layer-based image editor**: A Konva-powered editor at `/editor` with brushes, shapes, adjustments, filters, and curves.
- **Files library**: Save any result and reuse it as input to another tool.
- Pinned tools, in-canvas zoom and pan, 21 languages, and enterprise capabilities (OIDC/SSO, SAML, SCIM, S3 storage, per-tool permissions, audit export, distributed tracing).

### Improvements {#improvements}

- Cancel a running process. (#137)
- Full-resolution RAW decoding through LibRaw, including DNG. (#289)
- Non-root and foreign-UID deployments (TrueNAS, Unraid, OpenShift, PUID/PGID). (#230, #127)
- Accurate AI install detection and a hardened install flow. (#214, #352)
- Privacy hardening: no automatic third-party egress, plus an optional strict-offline mode.
- Always-on feedback button, even with analytics off.

### Bug fixes {#bug-fixes}

- `RATE_LIMIT_PER_MIN=0` disables rate limiting for tool routes again. (#271)
- Repaired AI virtualenv paths inside the Docker image. (#390)
- sharp 0.35.2+ compatibility. (#362)
- Image editor layout fixes: rulers, fill behavior, sidebar, and canvas sizing. (#258, #259)
- Completed the Italian translation. (#231, #206, #425)
- Audio normalize and loudnorm preserve the source sample rate.
- SSRF hardening: numeric IPv6 CIDR matching and a broadened URL pre-scan. (#287)
- Generated PDFs are stamped with SnapOtter as the Producer.
- mediapipe installs on Python 3.13 and Debian 13.

### Breaking changes {#breaking-changes}

2.0 replaces the embedded SQLite database with Postgres 17 and adds Redis 8 for the job queue. Your 1.x data migrates automatically on first boot, but the container stack changed, so back up your whole `/data` volume first (1.x runs SQLite in WAL mode, so the committed data usually lives in `snapotter.db-wal`). Then pick the single-container image (embedded Postgres and Redis, root only) or the Compose stack (app plus Postgres 17 and Redis 8). See the [migration guide](https://github.com/snapotter-hq/SnapOtter/blob/main/MIGRATING.md) and the [upgrade guide](/guide/upgrading).

### Upgrade {#upgrade}

```bash
docker pull snapotter/snapotter:2.0.0
```

Or with Docker Compose:

```bash
docker compose pull && docker compose up -d
```

## v1.17.0 {#v1-17-0}

Five new tools, a full image editor, SSO login, 20 languages. Probably should have been three separate releases, but here we are.

### New features {#new-features-3}

- **Image editor** - Layers, brushes, shapes, adjustments, filters, curves, keyboard shortcuts. Runs in your browser, processes on your hardware.
- **OIDC / SSO authentication** - Login with Google, GitHub, Okta, or any OpenID Connect provider. Set a few env vars and your team uses their existing accounts.
- **Meme generator** - 100 built-in templates with text rendering via opentype.js. Or upload your own image.
- **Beautify** - Drop a screenshot in, get a polished image out. Device frames (macOS, Windows, browser), shadows, gradients, social media presets.
- **Color blindness simulation** - Preview how images look with protanopia, deuteranopia, tritanopia, and other color vision deficiencies.
- **PNG transparency fixer** - Detects fake-transparent PNGs and fixes them with BiRefNet HR-matting. Optional watermark removal via LaMa inpainting.
- **AI canvas expand** - Extend image boundaries with AI fill. Three quality tiers (fast, balanced, quality) depending on how much GPU time you want to trade.
- **20 languages** - Arabic, Chinese (Simplified/Traditional), Czech, Dutch, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Thai, Turkish, Ukrainian, Vietnamese. RTL works for Arabic.
- **URL import** - Paste URLs into the dropzone or bulk-import from a list. Server-side fetch with SSRF protection.
- **Multi-file eraser** - Draw erase masks across multiple images, process them all with one click. Strokes persist per-image.
- **Pipeline import/export** - Save tool chains as JSON, share them with others.
- **17 new camera RAW formats** via exiftool, plus QOI, JP2, EPS, DDS, CUR, DPX, FITS, PPM/PGM/PBM, SVGZ, and APNG input. New output codecs for BMP, ICO, JP2, QOI. AVIF, TIFF, GIF, JXL, and PSD export recovered from a previously lost branch.

### Improvements {#improvements-2}

- **Image enhancement** - Replaced the old pipeline with CLAHE + normalise + gamma. New Deep Enhance toggle uses the AI model for more aggressive results.
- **Restore photo** - Scratch detection rewritten with 8-angle Otsu filtering. LaMa inpainting now runs at native resolution.
- **Exotic formats everywhere** - OCR, image-to-PDF, favicon generator, composition, stitch, and vectorize all decode HEIC, RAW, PSD now.
- **Compress** - Target-size tolerance tightened from 5% to 1%. Target size is the default mode. Added stepper buttons and KB/MB unit selector.
- **Sentry cleanup** - 644 non-actionable events filtered. Real errors now handled properly.
- **GPU detection** - Better diagnostics for containers where CUDA is present but nvidia-smi is not.
- **Auth-disabled mode** - Anonymous user is seeded in the DB with admin role. API keys, pipelines, and user files no longer break on FK constraints.
- **2,705+ new tests** across unit, integration, and E2E.

### Bug fixes {#bug-fixes-3}

- Upscale on CPU no longer times out on NAS boxes and low-power hardware.
- QR code logo no longer makes the preview vanish permanently.
- Crop overflow fixed for tall portrait images.
- TIFF alpha files correctly force PNG output instead of producing corruption.
- HDR/EXR decode converts to 8-bit before CLAHE, fixing decode failures.
- Face landmarks input buffers converted to PNG before the Python sidecar, fixing crashes.
- Find duplicates handles mixed-format batches and network errors.
- Beautify preview updates in real time.
- Progress bars for stitch and vectorize.
- SVGZ handled by SVG-to-raster.
