Preselection methods use now entry name extension and size for improving compression, while remaining 1-pass methods. For those interested about what's happening "under the hood", LZMA.Encoding now computes an estimation of the predicted probabilities of some alternative encodings and chooses the most probable one - it gives an immediate better local compression. Sometimes the repetition of such a repeated short-run improvement has a long-run positive effect, but sometimes not - that's where it's beginning to be fun...
