v2.15.7
This release is part of a larger story. Here's the short version:
Going independent
On March 25th, Patreon Trust & Safety removed the Stability Matrix page, under their policy against AI tools that can produce explicit imagery.
While we respect Patreon's right to govern their platform, banning us under this policy is exactly like banning a web browser because it can access NSFW sites, or banning VS Code because it can be used to write malware.
Our Stance
To be upfront: We believe software tools should not be restricted based on what users might hypothetically do with them. We will continue developing Stability Matrix exactly as it was meant to be – an open, unrestricted tool for the community.
The Community Response
Since the removal, the community's response has been incredible, and the message was clear: open-source tools should not be at the mercy of platform policies.
Building Something Better
That response is what made going independent possible. Stability Matrix is now directly supported by the people who use it, with no middlemen deciding what software is allowed to exist. Memberships at lykos.ai/membership, with significantly more of every contribution going into development.
Stability Matrix is free and open-source, and it always will be. That's not changing. Supporters fund development, servers, cross-platform builds, package compatibility work, and the people doing the work. If you believe in open-source tools that answer to their users, we'd love to have you with us.
What's new in v2.15.7
PNG metadata is finally spec-compliant for CJK users. If you've ever generated images with Japanese, Chinese, Korean, or emoji in your prompts and had them come out as mojibake when opened in other tools, that's fixed. Non-Latin-1 content now uses proper iTXt chunks with UTF-8 encoding (#1535).
Settings files are now self-healing. If your settings file gets corrupted from an interrupted write, crash, or power loss, SM will now automatically recover from null bytes, truncated JSON, and missing brackets instead of crashing on startup (#1590). Settings saves are also atomic now, so the corruption is less likely in the first place.
Better Japanese text rendering in dialogs — bundled NotoSansJP is now used for CTextBlock and ContentDialog, fixing compressed/squished text and incorrect fonts in markdown dialogs.
A wave of download reliability fixes — including downloads from CivitAI/HuggingFace redirects (e.g. CivArchive), VPN connection failures, the "request message was already sent" retry bug, and the progress bar showing 100% immediately on fresh downloads (#1598).
Plus a bunch of other stuff:
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
- 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 Stepsscheduler 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
CBoldandCItalicinline 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 - download progress bar showing 100% immediately for fresh downloads due to missing Content-Length fallback when Content-Range header is absent
- Fixed #1597 - reForge launch failing due to setuptools version
- Fixed #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 - 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 -
SocketException: Address already in useon Linux startup by cleaning stale interprocess socket files and reactivating the existing window - Fixed #1397, #610 - duplicate pip package entries in results - thanks to @e-nord!
