v1.1.0

Features

• Add support for bmap files (-b / --bmap): only mapped blocks are written, and their checksums are checked during verify
• Estimate progress for compressed images when the uncompressed size is unknown

Performance

• Use O_DIRECT for drive writes to skip the page cache, and raise the block size to 4 MB
• Pipeline copy and verify so that reading and decompressing run at the same time as drive I/O, with bounded memory use

Dependencies

• Replace libc with rustix for system calls
• Replace xz2 with liblzma, linked statically, so there is no runtime dependency on liblzma
