+## [1.0.0] — 2026-04-09
+
+### Features
+
+- GOG OAuth2 authentication — browser-based login, paste authorization code
+- Game library browser with checkboxes for management, DLCs as sub-items
+- Windows / Linux platform switcher in Library and Status tabs (games shown only for platforms where installers exist)
+- Per-language installer management — each language tracked independently, version comparison per language
+- Language selection tab — choose which languages to download globally
+- English-only mode — single toggle to skip language subfolders entirely
+- Bonus content support — soundtracks, wallpapers, manuals etc. stored in `GameName/Bonus/`
+- Per-game settings override — double-click any game in Library to configure languages, english-only and bonus per game
+- Folder name sanitization — strips ®, ™, replaces `:` with ` - `, collapses spaces
+- Version comparison — numeric dot-separated comparison with GOG suffix stripping; ambiguous versions ask user via dialog
+- Status tab — per-language version display, color-coded status (up to date, update available, not downloaded, unversioned)
+- Download with resume support (HTTP Range), real filename extracted from CDN URL
+- Prune old versions — keep N most recent, configurable per platform
+- Metadata integrity check — stale entries (manually deleted files) cleaned automatically on each check
+- Scan existing installers — detect already-downloaded files from correct folder structure and import into metadata
+- Version history dialog — double-click game in Status tab to see all downloaded versions with delete options
+- DLC installers stored in parent game's folder, not separate folders
+- Windows-only games do not download bonus content to Linux path and vice versa

+# GOGUpdater
+
+Desktop application (PySide6) for automatic management of GOG.com offline installers.
+
+## Description
+
+GOGUpdater authenticates with a GOG account via OAuth2, lets the user select which games to manage, and automatically downloads/updates offline installers (Windows .exe, Linux .sh) to local directories. The user has a clear overview of installer status and can trigger checks and downloads manually.
+
+## Current version
+
+**1.0.0** (2026-04-09)
+
+## Architecture
+
+### GUI — 5 tabs
+
+1. **Login** — OAuth2 flow, opens login URL in system browser, user pastes authorization code
+2. **Library** — owned games with management checkboxes, DLCs as sub-items; Windows/Linux platform switcher; double-click opens per-game settings
+3. **Languages** — select which languages to download globally; disabled when English-only mode is on
+4. **Settings** — Windows/Linux installer paths, English-only toggle, bonus content toggle, scan existing installers
+5. **Status** — installer status per platform (Windows/Linux switcher), check/download/prune controls; double-click opens version history dialog
+
+### Installer folder structure
+
+```
+/path/Game Name/1.63/English/setup_game.exe
+/path/Game Name/1.63/Czech/setup_game_cs.exe
+/path/Game Name/1.52/English/setup_game.exe    ← old version kept
+/path/Game Name/Bonus/soundtrack.zip           ← bonus content (no version subfolder)
+```
+
+Single-language games and English-only mode skip the language subfolder:
+```
+/path/Game Name/1.63/setup_game.exe
+```
+
+DLC installers are stored inside the parent game's folder.
+
+### Folder name sanitization
+
+Game titles are sanitized before use as folder names:
+- `:` → ` - `
+- Strips `®`, `™`, `©`
+- Removes invalid filesystem characters
+- Collapses multiple spaces
+
+### Metadata
+
+Each target path (windows/linux) contains `gogupdater.json` tracking downloaded installers and bonus files. Stale entries (files deleted outside the app) are cleaned automatically on each status check.
+
+```json
+{
+  "games": {
+    "1207658691": {
+      "name": "Cyberpunk 2077",
+      "latest_version": "1.63",
+      "managed": true,
+      "installers": [
+        {
+          "filename": "setup_cyberpunk_2077_1.63.exe",
+          "size": 12345678,
+          "version": "1.63",
+          "language": "en",
+          "installer_type": "game",
+          "downloaded_at": "2026-04-09T10:00:00"
+        }
+      ],
+      "bonuses": [],
+      "last_checked": "2026-04-09T10:00:00"
+    }
+  }
+}
+```
+
+### Application configuration
+
+Stored in `~/.config/gogupdater/`:
+- `auth.json` — OAuth2 tokens
+- `config.json` — paths, languages, managed games, english_only, include_bonus, per-game overrides
+
+### GOG API endpoints
+
+- `GET /user/data/games` — list of owned game IDs
+- `GET /products/{id}?expand=downloads,expanded_dlcs` — game info, installers, bonus content, DLCs
+- `POST https://auth.gog.com/token` — OAuth2 authentication and refresh
+
+### Download URL resolution
+
+GOG uses a two-level redirect: API downlink → JSON with CDN URL → actual file. The real filename is extracted from the CDN URL path (e.g. `setup_fallout_2.1.0.18.exe`).
+
+### Version comparison
+
+- Strips GOG suffixes like `(gog-3)` before comparing
+- Numeric dot-separated comparison
+- Ambiguous cases (e.g. `2.2(gog-3)` vs `2.3`) prompt the user via dialog
+- Non-version strings like `"bonus"` are treated as unversioned
+
+### Per-game settings
+
+Each game can override global settings:
+- Languages (which languages to download)
+- English-only (skip language subfolder)
+- Include bonus content
+
+Stored as `game_settings` in `config.json`. Default (no override) entries are not saved.
+
+## Modules (src/)
+
+- `auth.py` — authentication, token management
+- `api.py` — GOG API client (installers, bonus content, owned games)
+- `config.py` — application config, metadata store, scan/verify existing installers
+- `downloader.py` — installer and bonus file downloads with resume support
+- `models.py` — data structures (GameRecord, InstallerInfo, BonusContent, GameSettings, ...)
+- `version_compare.py` — version comparison with ambiguous case detection
+- `constants.py` — version, app title, debug mode
+- `ui/main_window.py` — main window with tab layout
+- `ui/tab_auth.py` — login tab
+- `ui/tab_library.py` — library tab with platform switcher
+- `ui/tab_languages.py` — language selection tab
+- `ui/tab_settings.py` — settings tab
+- `ui/tab_status.py` — status tab with platform switcher
+- `ui/dialog_game_settings.py` — per-game settings dialog
