0.7.1 (2020-09-18)

• bugfix release

0.7.0 (2020-08-27)

• the hook system (setup, extract, essential, customize and hook-dir) is made public and is now a documented interface
• tarball is also created if the output is a named pipe or character special

0.5.1 (2019-10-19)

• minor bugfixes and documentation clarification
• the --components option now takes component names as a comma or whitespace separated list or as multiple --components options
• make_mirror.sh now has to be invoked manually before calling coverage.sh

0.5.0 (2019-10-05)

• do not unconditionally read sources.list stdin anymore
  • if mmdebstrap is used via ssh without a pseudo-terminal, it will stall forever
  • as this is unexpected, one now has to explicitly request reading sources.list from stdin in situations where it's ambiguous whether that is requested
  • thus, the following modes of operation don't work anymore: $ mmdebstrap unstable /output/dir < sources.list $ mmdebstrap unstable /output/dir http://mirror < sources.list
  • instead, one now has to write: $ mmdebstrap unstable /output/dir - < sources.list $ mmdebstrap unstable /output/dir http://mirror - < sources.list

• create /var/lib/dpkg/cmethopt for dselect
• do not skip package installation in 'custom' variant
• fix EDSP output for external solvers so that apt doesn't mark itself as Essential:yes
• also re-exec under fakechroot if fakechroot is picked in 'auto' mode
• chdir() before 'apt-get update' to accomodate for apt << 1.5
• add Dir::State::Status to apt config for apt << 1.3
• chmod 0755 on qemu-user-static binary
• select the right mirror for ubuntu, kali and tanglu
