UNRELEASED

* The `chroot`(8) wrapper and `fakechroot`(1) command can work with POSIX
shell.

20 Nov 2016

* 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.

26 Oct 2015

* 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.

24 Dec 2013

* 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.

5 Dec 2013

* 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.

24 Nov 2013

* 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 overridden 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.
