v1.4.3

Compare Source

borgbackup 1.4.3

borg 1.4.x is kind of a refreshed 1.2 with mostly the same features and behavior, but a few bigger changes that could introduce issues and thus were not suitable for just releasing them as 1.2.x, but rather needed some testing first.

Long changelog:

Short borg 1.4 overview (from a borg 1.2 perspective):

Note:

• *-gh binaries are built on GitHub now. These Linux and FreeBSD binaries do support borg mount(FUSE filesystem), but the macOS binaries don't (use our brew tap!).
• I built and signed the borg-linux-glibc231-x86_64* binaries locally.
