Changes in version 1.2.0                        

    o   Deprecated rotate.all= in favour of get.all.genes= in
	multiBatchPCA().

    o   Switched BSPARAM= to use IrlbaParam(deferred=TRUE) by default
	in fastMNN(), so that the default behaviour is actually fast.

    o   Deprecated auto.order= in favor of merge.order= and auto.merge=
	in fastMNN() and mnnCorrect(). Automatic merging now detects
	potential tree-based merges. Merge trees can also be specified
	as input.

    o   Added the correctExperiments() function to cbind the original
	assays alongside the merged values.

    o   Added the subset.row= argument to cosineNorm() for in-place
	subsetting.

    o   Added batch= and preserve.single= arguments to
	multiBatchNorm(). Standardized behavior of subset.row= by
	adding a normalize.all= argument.

    o   Added the regressBatches() function for correction via standard
	linear regression.

    o   Added the prop.k= argument in all MNN-related functions, to
	allow the value of k to adapt asymmetrically to the size of
	each batch.

                        Changes in version 1.0.0                        

    o   
	New package batchelor, for batch correction of single-cell (RNA
	sequencing) data.
