* hans/ssh/printout_crash/OTP-14645:
  ssh: fix broken printouts

This function is intended primarily for users who want to experiment with the options preferred_algorithms and modify_algorithms.

If a user wants to enable one non-default algorithm or remove a default one, the option preferred_algorithms is too complicated since it replaces the whole set of algorithms.

* maint-20:
  Updated OTP version
  Prepare release
  Accept non-binary options as socket-options
  Bump version
  Fix broken handling of default values in extensions for PER
  compiler: Fix live regs update on allocate in validator
  Take fail labels into account when determining liveness in block ops
  Check for overflow when appending binaries, and error out with system_limit

Previously, a hard-coded atom (read_write) has been used as file owner access permission
in response to ssh_sftp:read_file_info/2 function. With this fix, the actual value of

from file mode value.

For example the option {raw,6,6,<<2,0,0,0>>}
