2.20.1

• Fixed problem when tests couldn't be started with root user and glibc 2.28.
• Fixed problem with too verbose test for debootstrap(8) command.
• Fixed problem with tests for fts_* functions when started on btrfs
  filesystem.
• The debootstrap(8) command honors FAKECHROOT_EXTRA_LIBRARY_PATH
  environment variable too.
• Workaround has been added for systemd package installed by
  debootstrap(8) command.
• Better support for link-time optimizer. Run
  ./configure EXTRA_CFLAGS='-Wall -flto' EXTRA_LDFLAGS='-flto' AR=gcc-ar NM=gcc-nm RANLIB=gcc-ranlib
  to use it.

2.20

• The fts64_* functions were added: glibc supports them since 2.23.
• The renameat2(2) function were added: glibc supports it since 2.28
  and mv command from coreutils 8.30 uses it.
• The chroot(8) wrapper and fakechroot(1) command can work with POSIX
  shell.
• The chroot(8) wrapper allows to chroot into root directory.
• The chroot(8) wrapper appends directories from
  FAKECHROOT_EXTRA_LIBRARY_PATH environment variable because some commands
  use runpath. The default value is /lib/systemd:/usr/lib/man-db for
  systemctl(1) and man(1) commands.
• The ldd(1) wrapper doesn't lose a leading slash in absolute paths.
• The fakechroot(1) command unsets CDPATH environment variable and swaps
  libfakeroot and libfakechroot in LD_PRELOAD environment variable if
  needed.
• Can be compiled with gcc 7.1 -Wformat-truncation.
• Can be compiled with clang 5.0 -O2 and -std=c11.

2.19

• The FAKECHROOT_EXCLUDE_PATH list has to contain at most 100 elements.
• The env(1) wrapper works with dash.
• The fakeroot(1) works if chroot(8) is invoked twice.
• Fixes were made for chdir(2). It was possible to change to a directory
  outside of fakechroot.
• The fakechroot(1) command sets FAKECHROOT_CMD_ORIG environment variable
  for wrapped command.
• The ldd(1) wrapper distinguishes different paths with the same beginning.
• The ldd(1) wrapper does not fail if the path is not existing outside
  fakechroot.
• Can be compiled with clang 4.0.

2.18

• The fakechroot(1) command accepts new option --bindir.
• The chfn(1) command runs correctly on Ubuntu vidid and Debian stretch.
• The env(1) wrapper works correctly if there is variable with multilined
  content.
• New functions ldaddr(3) and dl_iterate_phdr(3) were added. The
  dlopen(3) function was fixed. The java(1) command should work correctly.
• New functions posix_spawn(3) and posix_spawnp(3) were added. Some new
  applications like clang(1) should run properly.
• Fixes were made for lstat(2) and lstat64(2) functions. The ending
  slash is not removed by normalization of a path name.
• Fixes were made for readlink(2) function. The fakechroot(1) command runs
  properly with libjemalloc library.
• The tilde ~ character in FAKECHROOT_* variables is not expanded anymore.
• Fixes were made for getpeeraddr(3) and getsockaddr(3) functions.

2.17.2

• Fixes were made for fakechroot(1) command with -h option.
• The path for function chroot(2) is sanitized so it works correctly when
  path is ended with /.
• The make -n test was fixed and doesn't call any command.

2.17.1

• The fakechroot(1) command runs proper wrapper rather than original
  command, if it is listed on FAKECHROOT_CMD_SUBST variable.
• Fixes were made for chroot(8) wrapper. It scanned /etc/ld.so.conf
  incorrectly and now enters to physical path, avoiding symlinks.
• The chroot(2) function allows to use more than 2048 bytes for
  LD_LIBRARY_PATH environment variable.

2.17

• The FAKECHROOT_ELFLOADER environment variable changes the default dynamic
  linker. The fakechroot script provides --elfloader option.
• The FAKECHROOT_EXCLUDE_PATH environment variable overrides the default
  settings.
• The ldd(1) wrapper can work if overriden with FAKECHROOT_CMD_SUBST
  environment variable.
• New env(1) wrapper was added. It preserves fakechroot environment even
  for --ignore-environment option.
• The special environment none means that no environment settings are loaded
  at all.
• The function setenv(3) and unsetenv(3) was reimplemented, to prevent
  problems with binaries which brings own implementation of these functions.
• New function clearenv(3) was added. It preserves fakechroot environment.
• It is safe to use relative paths which won't escape from fake chroot.
• Fixes were made for readline(2) function if destination path is similar to
  FAKECHROOT_PATH.
• Fixes were made for mktemp(3) function if used on a path in
  FAKECHROOT_EXCLUDE_PATHS.
• The _xftw64(glibc) function is reenabled. It had wrong wrapper.
• Fixes were made for __realpath_chk(glibc) function when __chk_fail
  function is missing.
• New functions mkostemp(3), mkostemp64(3), mkostemps(3),
  mkostemps64(3), mkstemps(3) and mkstemps64(3) were implemented.
  It fixes sed -i command.

2.16

• The fakechroot script loads additional environment settings from
  configuration directory (--config-dir option). By default additional
  settings are provided for chroot(8) and debootstrap(8) commands.
• Wrapped chroot(8) command loads ld.so.conf paths to LD_LIBRARY_PATH
  environment variable.
• The debootstrap(8) command works with default, buildd and minbase
  variants.
• Fixes were made for getpeeraddr(3) and getsockaddr(3) functions.
  lwp-request command is working correctly.

2.15

• New function faccessat(2) was added. It fixes test -r command.
  Thanks to Johannes Schauer.
• The popen(3) function were reimplemented based on OpenBSD source to
  prevent some coredumps with newer GNU C Library.

2.14

• The source code was refactored: all functions was moved to separated files.
• The opendir(3) function is compiled only if it doesn't call other function
  internally. It fixes opendir(3), fts_open(3) and ftw(3) functions.
• The fts_*(3) functions were reimplemented based on OpenBSD source.
• The ftw_*(3) functions were reimplemented based on GNU C Library source.
• The __opendir2(3) function was reimplemented based on FreeBSD source.
• Fixes were made for older GNU C Library and for cross-compiling environment.
