Tarsnap 1.0.40 is now available. This version brings several improvements
compared to tarsnap 1.0.39:
* tarsnap now accepts a --resume-extract option to skip extracting files whose
filesize and mtime match existing files on disk.
* tarsnap now accepts --progress-bytes SIZE, which prints a progress message
after each SIZE bytes are processed, up to once per file. This can be
disabled with --no-progress-bytes.
* tarsnap now accepts a --passphrase method:arg option which accepts:
* --passphrase dev:tty-stdin
* --passphrase dev:stdin-once
* --passphrase dev:tty-once
* --passphrase env:VARNAME
* --passphrase file:FILENAME
* tarsnap now accepts a --dump-config option to print the command-line and all
non-blank lines read from config files.
* tarsnap now exits with an error if there are unused command-line arguments.
(i.e. "tarsnap -d -f a1 a2", where "a2" is unused.)
* Improved performance on some x86, amd64, and arm64 systems by using
cryptographic instruction set extensions.
* When sent SIGINFO or SIGUSR1, tarsnap now prints the number of files and the
number of uncompressed bytes processed, in addition to the previous output.
* A zsh completion file can be installed with
configure --with-zsh-completion=DIR.
As usual, there are also lots of minor build fixes, harmless bug fixes, and
code cleanups.
