Sylvania Launcher v3.0
New features
  • 2 launchers in 1 — game edition: a single button instantly switches between WoW 3.3.5a (WotLK) and WoW Legion 7.3.5. Logo, icon, background, accent color, realmlist, statistics and addon list follow the active edition, with no restart; the chosen edition is restored on the next launch.
  • 🎯 Three-state main button: Install (active edition's client missing), Progress (download/extraction) then Play (ready), with an automatic transition when installation finishes. The redundant "Download" button has been removed.
  • 📅 Enhanced notes: a calendar decorating days that carry a note or reminder, dated reminders with a native Windows notification + sound at due time (even with the launcher in the background), and missed reminders reported at startup.
  • 🎨 UI redesign: a centralized 3-level button system (primary/secondary/tertiary), a single spacing scale, fully layout-based arrangement and keyboard navigation; identical skeleton across both editions, dark theme and dynamic backgrounds preserved.
  • 🐺 Fully operational Legion 7.3.5 client: .tar.gz download (44.4 GB) written straight to disk with free-space check, size + SHA-256 integrity verified before extraction, path-traversal guard on the archive, and authentication portal written to Config.wtf before launch.
⚙️ Miscellaneous
  • Per-edition configuration and statistics, with automatic migration from v2.9.
  • Separate addon manifest for Legion (never mixed with the 3.3.5 list).
  • HD patch and enUS pack cleanly reserved for the WotLK edition.
  • Complete FR/EN i18n (325 strings), binary metadata at 3.0.0.0.
Sylvania Launcher v2.9
New features
  • Recommended addons (14 popular addons): one-click install, update and uninstall, with progress bar and status indicators.
  • Full AddOn manager: Recommended / Catalog / Installed tabs, with support for multi-folder addons (DBM, Details!, ElvUI…).
  • Addon removal: an "Installed" tab that scans Interface/AddOns (name, version, size) with multi-selection and confirmed deletion.
  • Resizable window: saved/restored geometry, multi-monitor support and High-DPI compatibility.
  • New logo and version 2.9 metadata.
Improvements & fixes
  • Fixed memory leaks (QNetworkReply / QProcess).
  • Fixed a race condition in game process tracking.
  • Atomic writing of the Config.wtf file.
  • Updated French and English translations.
Sylvania Launcher v2.8
New features
  • Redesigned HD Patch management
  • Random background: new 🎲 button next to the background selector.

Improvements & fixes
  • HD Pack download: removed the obsolete "PatchMenu" migration entry.
  • English translations completed for the new strings.
  • Updated showcase screenshots.
  • Hardened core (security/perf): atomic writes, ConfigManager/NotesManager, DownloadDialog.
