 Package: Seurat
-Version: 5.1.0
-Date: 2024-05-08
+Version: 5.2.0
 Title: Tools for Single Cell Genomics
 Description: A toolkit for quality control, analysis, and exploration of single cell RNA sequencing data. 'Seurat' aims to enable users to identify and interpret sources of heterogeneity from single cell transcriptomic measurements, and to integrate diverse types of single cell data.

+# Seurat 5.2.0 (2024-12-20)
+
+## Changes
+- Added `group.by` parameter to `FindAllMarkers`, allowing users to regroup their data using a non-default identity class prior to performing differential expression ([#9550](https://github.com/satijalab/seurat/pull/9550))
+- Added `image.type` parameter to `Read10X_Image` enabling `VisiumV1` instances to be populated instead of instances of the default `VisiumV2` class ([#9556](https://github.com/satijalab/seurat/pull/9556))
+- Fixed `IntegrateLayers` to respect the `dims.to.integrate` parameter
+- Added `stroke.size` parameter to `DimPlot` ([#8180](https://github.com/satijalab/seurat/pull/8180))
+- Updated `RunLeiden` to use the `leidenbase` package instead of `leiden`; deprecated the `method` parameter for `RunLeiden` and `FindClusters`; updated `RunLeiden` to reset `random.seed` to 1 if the value is 0 or less ([#6792](https://github.com/satijalab/seurat/pull/6792))
+- Updated `RunPCA` to use the `BPCells`-provided SVD solver on `BPCells` matrices; updated `JackStraw` to support `BPCells` matrices ([#8271](https://github.com/satijalab/seurat/pull/8271))
+- Fixed `RunPCA` to avoid converting `BPCells` matrices into dense matrices - significantly reduces the function's memory usage when running on `BPCells` matrices ([#8966](https://github.com/satijalab/seurat/pull/8966))
+- Updated `RunSLSI` to support `BPCells` matrices
+- Updated `RunUMAP` to support `umap-learn` version >= 0.5.0 ([#9559](https://github.com/satijalab/seurat/pull/9559))
+- Updated `LoadXenium` and `ReadXenium` to accommodate the output from `XOA` v3.0; updated `LoadXenium` to provide more fine-grained control over the datatypes parsed in, including nucleus segmentation masks, segmentation methods, and other experimental metadata; updated `ReadXenium` to load cell_feature_matrix.h5 when present in favor of the MEX format files; updated `ReadXenium` to load .parquet files using `arrow` instead of .csv.gz files to support XOA 3.0 ([#8604](https://github.com/satijalab/seurat/pull/8605))
+- Fixed `LoadXenium` to accommodate datasets without "Blank Codeword" or "Unassigned Codeword" matrices([#9135](https://github.com/satijalab/seurat/pull/9135))
+- Fixed `ReadXenium` to properly parse multiple molecular outputs at once ([#8265](https://github.com/satijalab/seurat/issues/8265))
+- Added `features` parameter to `LeverageScore` and `SketchData`
+- Updated `SketchData`'s `ncells` parameter to accept integer vector
