0.8.1 (2021-10-07)
|
||||
------------------
|
||||
|
||||
- enforce dpkg >= 1.20.0 and apt >= 2.3.7
|
||||
- allow working directory be not world readable
|
||||
- do not run xz and zstd with --threads=0 since this is a bad default for
|
||||
machines with more than 100 cores
|
||||
- bit-by-bit identical chrootless mode
