git-annex 7.20190730 released with these changes

  • Improved probing when CoW copies can be made between files on the same drive. Now supports CoW between BTRFS subvolumes. And, falls back to rsync instead of using cp when CoW won't work, eg copies between repos on the same EXT4 filesystem.
  • Add BLAKE2BP512 and BLAKE2BP512E backends, using a blake2 variant optimised for 4-way CPUs.
  • Support running v7 upgrade in a repo where there is no branch checked out, but HEAD is set directly to some other ref.
  • Windows build no longer ships with a copy of rsync, since that is only used any more to access rsync special remotes or remotes with a very old version of git-annex-shell.
  • Windows build is now 64 bit, and using it with the 64 bit git for Windows is fully supported.
  • Windows problems with long filenames should be fixed now, since the Windows build is made with a newer ghc version that works around the problems.
  • stack.yaml: Build with http-client-0.5.14 to get a bug fix to http header parsing.
  • Drop support for building with ghc older than 8.4.4, and with older versions of serveral haskell libraries.
  • Support building with socks-0.6 and persistant-template-2.7.
  • Corrected some license statements. Thanks, Sean Whitton.
