feedback, but the 2.5 branch is shaping up nicely.) In addition to many small bug fixes and code improvements: * Another iteration of versioning; I think I've got it right now. * Portability: A lot of progress on Windows support (though I'm not committing all of the Windows support files to FreeBSD CVS) * Explicit tracking of MBS, WCS, and UTF-8 versions of strings in archive_entry; the archive_entry routines now correctly return NULL only when something is unset, setting NULL properly clears string values. Most charset conversions have been pushed down to archive_string. * Better handling of charset conversion failure when writing or reading UTF-8 headers in pax archives * archive_entry_linkify() provides multiple strategies for hardlink matching to suit different format expectations * More accurate bzip2 format detection * Joerg Sonnenberger's extensive improvements to mtree support * Rough support for self-extracting ZIP archives. Not an ideal approach, but it works for the archives I've tried. * New "sparsify" option in archive_write_disk converts blocks of nulls into seeks. * Better default behavior for the test harness; it now reports all failures by default instead of coredumping at the first one.
