 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.

 ## Added
-- Expose `FoldChange()` component in `FindMarkers()`. 
+- Add direction option to `PlotClusterTree()`
+- Add `cols` parameter to `JackStrawPlot()`
+- Add `ReadMtx()` to read local and remote mtx files with associated cell and feature name files
+
+## Changes
+- Equality added to differential expression thresholds in `FindMarkers` (e.g, >= logfc.threshold rather than >)
+- `Read10X()` now prepends dataset number for first dataset when reading multiple datasets
+- Bug fix for `subset.AnchorSet()`
+- Bug fix for fold change values in `FindMarkers()` when setting a different pseudocount ([#4111](https://github.com/satijalab/seurat/pull/4111))
+- Bug fix for `RunLDA()` related to proper passing of assay parameter.
+- When using `order=TRUE` in `SingleDimPlot()`, print NA points under all others.
+- Remove default parameter value for `data.dir` in `Read10X()`
+- Import spatstat fxns from subpackages (spatstat.core, spatstat.geom)
+- `RunUMAP` now checks for graph/neighbor consistency

 - Add `PredictAssay()` to impute expression or embeddings from nearest neighbors
 - Add `Graphs()` function to access the names of the stored Graph objects or pull a specific one
 - Add checks for NA, NaN, logical, non-integer, and infinite values during CreateAssayObject and NormalizeData.default
 - Add `AnnotateAnchors()` to aid in AnchorSet interpretation as well as `subset.AnchorSet()`
 - Add flexibility of choice for cell column in `Read10X()`
 - Add rasterization option to `FeatureScatter()` and `VariableFeaturePlot()`
+- Add step1 feature parameters in the SCTModel via `PrepVSTResults()`
 
 ## Changes
 - Default neighbor finding algorithm changed from "rann" to "annoy"
 - Default `ncells` parameter in `SCTransform()` changed to 5000
 - Default fold change in `FindMarkers()` changed from ln to log2
 - Implementation improvements to `AverageExpression()`
-- `AnchorSet` class re-implemented as a virtual class from which `IntegrationAnchorSet` and `TransferAnchorSet` now inherit. 
+- `AnchorSet` class re-implemented as a virtual class from which `IntegrationAnchorSet` and `TransferAnchorSet` now inherit.
 - Point size in `VlnPlot()` now set automatically if not specified
 - Return the sample.tree properly when integrating with a single reference dataset
 - Replace `as.character.quosure` usage with `as_label` due to deprecation
 - Minor changes to the exact calculation of the anchor weight matrix
 - Default rasterization limit in `DimPlot()` and `FeaturePlot()` changed from 50,000 to 100,000
 - `SCTransform()` now returns a formalized `Assay` subclass `SCTAssay()`
 - When using `normalization.method='SCT'` in `FindTransferAnchors()`, normalize query using reference SCT model when possible.
+- Change default Neighbor name in `FindNeighbors` to `Assay.nn`
 
 ## Removed
 - `CreateGeneActivityMatrix` replaced by `Signac::GeneActivity()`
