 # Jackify Changelog
 
+## v0.2.1.1 - Bug Fixes and Improvements
+**Release Date:** 2026-01-15
+
+### Critical Bug Fixes
+- **AppImage Crash on Steam Deck**: Fixed `NameError: name 'Tuple' is not defined` that prevented AppImage from launching on Steam Deck. Added missing `Tuple` import to `progress_models.py`
+
+### Bug Fixes
+- **Menu Routing**: Fixed "Configure Existing Modlist (In Steam)" opening wrong section (was routing to Wabbajack Installer instead of Configure Existing screen)
+- **TTW Install Dialogue**: Fixed incorrect account reference (changed "mod.db" to "ModPub" to match actual download source)
+- **Duplicate Method**: Removed duplicate `_handle_missing_downloader_error` method in winetricks handler
+- **Issue #142**: Removed sudo execution from modlist configuration - now auto-fixes permissions when possible, provides manual instructions only when sudo required
+- **Issue #133**: Updated VDF library to 4.0 for improved Steam file format compatibility (protontricks 1.13.1+ support)
+
+### Features
+- **Download Size Display**: Added total download size display in GB during modlist installation
+- **Download Size Formatting**: Improved display to show MB when remaining download is less than 1GB (fixes "0.0GB remaining" for small files like .wabbajack)
+- **ETA Display**: Added estimated time remaining (ETA) during downloads with smoothing to prevent wild fluctuations
+- **Concurrent Download ETA**: Improved ETA calculation for concurrent downloads by summing speeds from all active files
+- **Wine Component Error Handling**: Enhanced error messages for missing downloaders with platform-specific installation instructions (SteamOS/Steam Deck vs other distros)
+
+### Improvements
+- **Download Progress Tracking**: Enhanced parser to track running totals from all files seen during download phase, improving remaining size/ETA accuracy when engine doesn't report overall totals
+- **Note**: Archive downloads still require engine changes to show complete overall totals (see `docs/PlanOfAction.md` for details)
+
+### Dependencies
+- **VDF Library**: Updated from PyPI vdf 3.4 to actively maintained solsticegamestudios/vdf 4.0 (used by Gentoo)
+- **Winetricks**: Removed bundled downloaders that caused segfaults on some systems - now uses system-provided downloaders (aria2c/wget/curl)

 ## v0.2.1 - Wabbajack Installer and ENB Support
 **Release Date:** 2025-01-12
-
+Y
 ### Major Features
 - **Automated Wabbajack Installation**: While I work on Non-Premium support, there is still a call for Wabbajack via Proton. The existing legacy bash script has been proving troublesome for some users, so I've added this as a new feature within Jackify. My aim is still to not need this in future, once Jackify can cover Non-Premium accounts.
 - **ENB Detection and Configuration**: Automatic detection and configuration of `enblocal.ini` with `LinuxVersion=true` for all supported games
