1.8.0
* Dropped support for Python 3.4.
* Fixed internal leak that should make
``execnet`` execute remote code in the main thread more often; previously it would sometimes
spawn a thread to execute a ``remote_exec`` call, even when the caller
didn't issue multiple ``remote_exec`` calls at the same time. Some frameworks require code
to execute in the main thread, so the previous behavior would break them on occasion.
* Current working directory is now
restored when calling ``script/socketserver.py``. The script now also loops by default
when called from the command-line.
