v0.0.62 Major change: derfinder no longer uses parallel::mclapply() or parallel::mcmapply(). Instead it uses BiocParallel::bplapply() and bpmapply() along with SnowParam() when mc.cores is greater than 1. Using SnowParam() instead of MulticoreParam() which would have been the equivalent means that the memory no longer blows up (exponetially) when mc.cores increases; instead it increases nearly linearly. It also means that derfinder no longer chokes with the 'long vectors not yet implemented' issue with using mclapply(): at least one previous reproducible case no longer throws this error.
