Expyriment 0.9.0 released!

[Florian Krause]

Expyriment 0.9.0 has just been released!

This release includes many new features as well as important changes and bug

fixes (for a full list, please see below).

Most importantly, Expyriment is now compatible with Python 3 (in addition to Python 2)!

You can install the new version via pip:

    pip install -U expyriment

For detailed installation instructions, please see http://docs.expyriment.org/Installation.html.

We would also like to take the opportunity to announce the new official Expyriment forum at http://forum.expyriment.org,
as well as the official Expyriment Matrix channel at #freenode_#expyriment:matrix.org (bridged to the official Expyriment IRC channel!)

New Features:
- Python 3 compatibility
- New Video stimulus implementation that supports a large range of formats
- new global boolean constant expyriment.PYTHON3 indicates Python version
- new io device: io.extras.TcpServer
- new method to add full factorial designs:
  Block.add_trials_full_factorial & Experiment.add_blocks_full_factorial
- Network inteface to Turbo-Satori: io.extras.TurbosatoriNetworkInterface
  (see www.brainvoyager.com/products/turbosatori.html)
- stimuli.Rectangle: Option to have rounded (anti-aliased) corners
- rotate() method of stimuli applies filtering on the content now
- randomize.coin_flip() with bias parameter ("unfair coins")
- randomize.rand_norm() normally distributed random numbers
- statistics module: std & variance
- Eventfile.log has an optional log_event_tag for the logging of
  inter-event-intervalls. If this is defined a summary of the intervalls
  will be added to the event file.
- All present methods have an optional log_event_tag that will be passed
  to Eventfile.log (see above)
- New function: misc.has_internet_connection()
- Notify when initializing system fonts takes longer
- io.ParallelPort: new method get_driver()
- New function: misc.which()

Changed:
- all wait methods (io and Clock) now
    (1) have process_control_events attribute to check for quit events from
        keyboard and mouse
    (2) have function attribute (callback_function) to repeatedly run a
        specific function in every loop iteration
    (3) pump the pygame event queue to (hopefully) prevent the OS to think the
        window is "not responding"
- control.set_develop_mode: new skip_wait_methods attribute to ommit all wait 
  functions in the experiment (for testing)
- rename method: stimulus.replace --> stimulus.reposition
- improvements to io.extras.TcpClient
- move set_skip_wait_functions from misc to io
- move is_idle_running, is_interactive_mode, is_android_running
  from control to misc
- move get_module_hash_dictionary, get_experiment_secure_hash,
  module_hashes_as_string and get_system_info from expyriment to misc
- Testsuite: Visual test will now colour code reported refresh rates

Fixed:
- unicode bug on Windows for font files
- unicode bug on Windows for Audio and Picture
- bug fix in unicode2str
- bug fix Experiment.add_experiment_info
- bug: issue #65, tempfolder at multiuser systems
- minor bug fixes in _secure_hash.py, _files.py
- Cli: -0 option was not recognized
- Correct anti-aliasing for Circle/Ellipse (now works on every background)
- compatibility with pyserial version 3.0
- ParallelPort: inpoutx64 should now work correctly
