-----

* Added ``islink()`` and ``unlink()`` to path objects (`100 <https://github.com/tomerfiliba/plumbum/pull/100>`_,

* Faster ``which`` implementation (`98 <https://github.com/tomerfiliba/plumbum/pull/98>`_)
* Several minor bug fixes

---
* Moved ``atomic`` and ``unixutils`` into the new ``fs`` package (file-system related utilities)
* Dropped ``plumbum.utils`` legacy shortcut in favor of ``plumbum.path.utils``
* Bugfix: the left-hand-side process of a pipe wasn't waited on, leading to zombies (`89 <https://github.com/tomerfiliba/plumbum/pull/89>`_)
* Added ``RelativePath`` (the result of ``Path.relative_to``)
* Fixed more text alignment issues in ``cli.Application.help()``
* Introduced ``ask()`` and ``choose`` to ``cli.terminal``
* Bugfix: Path comparison operators were wrong
* Added connection timeout to ``RemoteMachine``

---
* ``Command.popen``: a new argument, ``new_session`` may be passed to ``Command.popen``, which runs the given
in a new session (``setsid`` on POSIX, ``CREATE_NEW_PROCESS_GROUP`` on Windows)
* ``Command.Popen``: args can now also be a list (previously, it was required to be a tuple). See
* ``local.daemonize``: run commands as full daemons (double-fork and ``setsid``) on POSIX systems, or
detached from their controlling console and parent (on Windows).
* ``list_processes``: return a list of running process (local/remote machines)
* ``SshMachine.nohup``: "daemonize" remote commands via ``nohup`` (not really a daemon, but good enough)
* ``atomic``: Atomic file operations (``AtomicFile``, ``AtomicCounterFile`` and ``PidFile``)
* ``copy`` and ``move``: the ``src`` argument can now be a list of files to move, e.g., ``copy(["foo", "bar"], "/usr/bin")``
* list local and remote processes
* cli: better handling of text wrapping in the generated help message
* cli: add a default ``main()`` method that checks for unknown subcommands
* terminal: initial commit (``get_terminal_size``)
* packaging: the package was split into subpackages; it grew too big for a flat namespace.
imports are not expected to be broken by this change
* SshMachine: added ``password`` parameter, which relies on `sshpass <http://linux.die.net/man/1/sshpass>`_ to feed the
password to ``ssh``. This is a security risk, but it's occasionally necessary. Use this with caution!
* Commands now have a ``machine`` attribute that points to the machine they run on
* Commands gained ``setenv``, which creates a command with a bound environment
* Remote path: several fixes to ``stat`` (``StatRes``)
* cli: add lazily-loaded subcommands (e.g., ``MainApp.subcommand("foo", "my.package.foo.FooApp")``), which are imported
on demand
* Paths: added `relative_to and split <https://github.com/tomerfiliba/plumbum/blob/c224058bcefaf5c00fe2295389887c7ebc9d5132/tests/test_local.py#L53>`_,
which (respectively) computes the difference between two paths and splits paths into lists of nodes
* cli: ``Predicate`` became a class decorator (it exists solely for pretty-printing anyway)
* PuttyMachine: `bugfix <https://github.com/tomerfiliba/plumbum/pull/85>`_

---
* Path: added `chmod <https://github.com/tomerfiliba/plumbum/pull/49>`_
* Path: added `link and symlink <https://github.com/tomerfiliba/plumbum/issues/65>`_
* Path: ``walk()`` now applies filter recursively (`64 <https://github.com/tomerfiliba/plumbum/issues/64>`_)
* Commands: added `Append redirect <https://github.com/tomerfiliba/plumbum/pull/54>`_
* Commands: fix ``_subprocess`` issue (`59 <https://github.com/tomerfiliba/plumbum/issues/59>`_)
* Commands: add ``__file__`` to module hack (`66 <https://github.com/tomerfiliba/plumbum/issues/66>`_)
* Paramiko: add `'username' and 'password' <https://github.com/tomerfiliba/plumbum/pull/52>`_
* Paramiko: add `'timeout' and 'look_for_keys' <https://github.com/tomerfiliba/plumbum/pull/67>`_
* Python 3: fix `56 <https://github.com/tomerfiliba/plumbum/issues/56>`_ and `#55 <https://github.com/tomerfiliba/plumbum/pull/55>`_
