Notable changes in 0.28.1 as compared to 0.28

General

Builds from unpacked release archives (created via "git archive TAG") should work again.

Build system

test-web.sh and test-meta.sh should now work on newer versions of OS X, and with Homebrew rsync.
cmd/bup-python's permissions should now respect the umask.

Thanks to (at least)

Gernot Schulz, Karl Semich, Rob Browning, and ilovezfs
