Changes in version 1.30.0 o Migrated createClusterMST() to the TrajectoryUtils package. o Modified orderCells() to return a more informative PseudotimeOrdering object. o Handle pseudotime matrices in testPseudotime() by testing each path separately. Support inclusion of custom row.data= in each output DataFrame. Changes in version 1.28.0 o Added createClusterMST() to create a cluster-based MST from a variety of inputs, migrated from the scran package. o Added reportEdges() to report edge coordinates for plotting. o Added mapCellsToEdges() to map cells to the closest edge on the MST. o Added orderCells() to compute a pseudotemporal ordering from mapped cells. o Added quickPseudotime() to wrap MST construction and ordering into a single call. o Added testPseudotime() to test for DE genes along one or more paths through a MST. o Added the rowmean() utility to compute column means for row groupings. o Added perCellEntropy() to compute per-cell entropies across various matrix types.
