@@ -5,6 +5,18 @@ All notable changes to Stability Matrix will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning 2.0](https://semver.org/spec/v2.0.0.html).
 
+## v2.5.2
+### Added
+- Right click Inference Batch options to enable selecting a "Batch Index". This can be used to reproduce a specific image from a batch generation. The field will be automatically populated in metadata of individual images from a batch generation.
+  - The index is 1-based, so the first image in a batch is index 1, and the last image is the batch size.
+  - Currently this generates different individual images for batches using Ancestral samplers, due to an upstream ComfyUI issue with noise masking. Looking into fixing this.
+- Inference Batches option now is implemented, previously the setting had no effect
+### Changed
+- Default upscale factor for Inference is now 2x instead of 1x
+### Fixed
+- Fixed batch combined image grids not showing metadata and not being importable
+- Fixed "Call from invalid thread" errors that sometimes occured during update notifications
+
 ## v2.5.1
 ### Added
 - `--skip-install` default launch argument for Automatic1111 Package
