 ## v2.15.7
+### Added
+- Added single-instance window activation signaling so reopening the app restores and focuses the existing desktop window instead of launching a duplicate instance
+- Added notification system with localizable banner and markdown detail dialog UI
+- Added warning in data directory selector when an OneDrive folder is selected
+- Added support in the Checkpoints page to distinguish standard updates from Early Access-only updates - thanks to @x0x0b!
+- Added torch index for Strix/Gorgon Point Ryzen AI APUs on Windows - thanks to @NeuralFault!
+- Added retry button to failed downloads - thanks to @NeuralFault!
+- Added new Membership support in Account Settings with Patreon migration prompt
 ### Changed
 - Settings file saves are now atomic to prevent corruption from interrupted writes
-### Fixed
+- Updated torch indexes for A1111, ComfyUI, InvokeAI, and Forge-based UIs to rocm7.2 / cu128 depending on GPU - thanks to @NeuralFault!
+- Replaced the "Become a Patron" footer button with "Support Us", linking to the new direct Lykos support page at lykos.ai/membership
+- Updated the prompt dialog shown when enabling features like Accelerated Model Discovery to use Lykos accounts instead of Patreon linking
+- Moved the Patreon connection in Account Settings to a new "Legacy Connections" section, only shown for users with an existing Patreon link
+- Localized previously hardcoded strings on the Account Settings page (menu items, descriptions, section headers) and added Japanese, Korean, German, and French translations
+### Fixed
+- Fixed an issue where `Align Your Steps` scheduler and Unet Loader workflows ignored Regional Prompting (and other addon) conditioning modifiers.
+- Fixed the Package Manager "Add Package" teaching tip opening inopportunely while packages were still loading or after opening the add-package dialog
+- Fixed bold text not rendering in markdown dialogs on Windows 11 due to Avalonia 11.3.x variable font regression with Segoe UI Variable Text
+- Fixed Japanese text appearing compressed/squished in markdown dialogs by ensuring the bundled NotoSansJP font is used for CTextBlock rendering
+- Fixed ContentDialog title and buttons not using the correct font for Japanese locale (NotoSansJP) when shown as overlay
+- Added missing `CBold` and `CItalic` inline styles to the markdown style sheet
+- Fixed downloads failing with "The request message was already sent" when the server doesn't return Content-Length on the first attempt, caused by reusing a consumed HttpRequestMessage in the retry loop
+- Fixed downloads from sources that redirect to CivitAI/HuggingFace (e.g. CivArchive) failing with Unauthorized by resolving the redirect target URL and applying auth headers for the correct domain
+- Fixed dropdown menu overlayed in Inference UI Model Cards not being scrollable on Linux - thanks to @NeuralFault!
+- Fixed model downloads failing on VPN connections - thanks to @NeuralFault!
+- Fixed [#1598](https://github.com/LykosAI/StabilityMatrix/issues/1598) - download progress bar showing 100% immediately for fresh downloads due to missing Content-Length fallback when Content-Range header is absent
+- Fixed [#1597](https://github.com/LykosAI/StabilityMatrix/issues/1597) - reForge launch failing due to setuptools version
+- Fixed [#1596](https://github.com/LykosAI/StabilityMatrix/issues/1596) - package installs and managed embedded Python startup being poisoned by inherited shell Python activation variables such as `PYTHONHOME`, `PYTHONPATH`, `VIRTUAL_ENV`, and Conda environment variables
 - Fixed [#1590](https://github.com/LykosAI/StabilityMatrix/issues/1590) - Startup crash when settings file is corrupted. Settings files are now self-healing with automatic recovery from null bytes, truncated JSON, and missing brackets
+- Potentially fixed [#1578](https://github.com/LykosAI/StabilityMatrix/issues/1578) - `SocketException: Address already in use` on Linux startup by cleaning stale interprocess socket files and reactivating the existing window
+- Fixed [#1397](https://github.com/LykosAI/StabilityMatrix/issues/1397), [#610](https://github.com/LykosAI/StabilityMatrix/issues/610) - duplicate pip package entries in results - thanks to @e-nord!
