I've had private mail on this topic too, making it the most contested feature of the new Exim release. That ... says something. GnuTLS and some other projects now ship only .xz and .lz tarballs, with the .lz being smaller. I'm not going to add *two* new compression formats. It's not even certain that I'll add one. When looking, I picked the one which gave smaller files for Exim's main source tarball. The only reason to use Yet Another compression format is to have smaller resulting files. If we add a new compression format, it will be the one which compresses better. Compatibility is not an issue, since gzip/bzip2 provide compatibility. (Licensing would be an issue if any contender were antagonistic to the GPL, which Exim uses). I note from Wikipedia that coreutils uses .gz and .xz and the Linux kernel supports .xz, but when I look at Linus' tree, I see that lzma is handled too. The gentoo claim is about .lzma being replaced by .xz, but .lzma is not the same as .lz. My source for this claim is: http://www.nongnu.org/lzip/lzip.html -Phil -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
