+
+## v2.10.1
+### Added
+- Added SVD Shared Model & Output Folders for Forge (fixes [#580](https://github.com/LykosAI/StabilityMatrix/issues/580))
+### Changed
+- Improved error message when logging in with a Lykos account fails due to incorrect email or password
+- Model Browser & Workflow Browser now auto-load when first navigating to those pages
+- Removed update confirmation dialog, instead showing the new version in the update button tooltip
+### Fixed
+- Fixed package launch not working when environment variable `SETUPTOOLS_USE_DISTUTILS` is set due to conflict with a default environment variable. User environment variables will now correctly override any default environment variables.

+## v2.10.0
+### Added
+- Added Reference-Only mode for Inference ControlNet, used for guiding the sampler with an image without a pretrained model. Part of the latent and attention layers will be connected to the reference image, similar to Image to Image or Inpainting.
+- Inference ControlNet module now supports over 42 preprocessors, a new button next to the preprocessors dropdown allows previewing the output of the selected preprocessor on the image.
+- Added resolution selection for Inference ControlNet module, this controls preprocessor resolution too.
+- Added Layer Diffuse sampler addon to Inference, allows generating foreground with transparency with SD1.5 and SDXL.
+- Added support for deep links from the new Stability Matrix Chrome extension
+- Added OpenArt.AI workflow browser for ComfyUI workflows
+- Added more metadata to the image dialog info flyout
+- Added Output Sharing toggle in Advanced Options during install flow
+### Changed
+- Revamped the Packages page to enable running multiple packages at the same time
+- Changed the Outputs Page to use a TreeView for the directory selection instead of a dropdown selector
+- Model download location selector now searches all subfolders
+- Inference Primary Sampler Addons (i.e. ControlNet, FreeU) are now inherited by Hires Fix Samplers, this can be overriden from the Hires Fix module's settings menu by disabling the "Inherit Primary Sampler Addons" option.
+- Revisited the way images are loaded on the outputs page, with improvements to loading speed & not freezing the UI while loading
+- Updated translations for French, Spanish, and Turkish
+- Changed to a new image control for pages with many images
+- (Internal) Updated to Avalonia 11.0.10
