+\item Switch to \pkg{scrapper} for DE detection when \code{de.method="t"} or \code{de.method="wilcox"} in \code{trainSingleR()}.
+This should give similar results to but is faster than the previous \pkg{scran} functions.

+This should be faster than the previous \pkg{BiocSingular} and \code{stats::kmeans} functions, and avoids the need to consider the seed.

 \section{Version 2.8.0}{\itemize{
 \item Added the \code{test.genes=} argument to \code{trainSingleR()}, to restrict marker detection to only those genes in the test dataset.
 This is also checked against \code{rownames(test)} in \code{classifySingleR()} to ensure that the test's feature space is consistent with the space used during training.
