 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.

+- Add `lsiproject` and `rpca` options for `FindTransferAnchors()`
+- Add `rlsi` option for `FindIntegrationAnchors()`
+
+## Changes
+- Preserve feature metadata when converting from `SingleCellExperiment` to `SeuratObject` class
+([#4205](https://github.com/satijalab/seurat/issues/4205))
+- Preserve multiple assays when converting from `SingleCellExperiment` to `SeuratObject` class
+([#3764](https://github.com/satijalab/seurat/issues/3764))
+- Fix passing of `score.thresh` parameter in `ScoreJackStraw()` ([#4268](https://github.com/satijalab/seurat/pull/4268))
+- Fix FC calculation in `FindMarkers()` non-log transformed data.
+- Add umap-learn version >= 0.5.0 compatibility for `RunUMAP()`
+- Fix `DotPlot` to use `log1p` when `scale=False`
+([#4298](https://github.com/satijalab/seurat/issues/4298))
+- Fix split and shuffled `DimPlot`
+- Disallow NULL or another length 0 vector for `ident.1` in `FindMarkers()`
+- Fix range shift when labeling clusters on a GeomSpatial plot
+- Fix SpatialPlot distortion for non-square images.
+- Fix future-related warnings in `FindIntegrationAnchors()`
+- Fix `fc.name` parameter in `FindMarkers()` ([#4474](https://github.com/satijalab/seurat/issues/4474))
