• More logging, especially around ignore file discovery and filtering
• The const paths::PATH_SEPARATOR is now public, being : on Unix and ; and Windows.
• Add Subversion to discovered ProjectTypes
• Add common (sub)Filterer for ignore files, so they benefit from a single consistent implementation. This also makes ignore file discovery correct and efficient by being able to interpret ignore files which searching for ignore files, or in other words, not descending into directories which are ignored.
• Integrate this new IgnoreFilterer into the GlobsetFilterer and TaggedFilterer. This does mean that some old v1 behaviour of patterns in gitignores will not behave quite the same now, but that was arguably always a bug. The old "buggy" v1 behaviour around folder filtering remains for manual filters, which are those most likely to be surprising if "fixed".
