Changelog

2.1.1

------------------

Bugfixes
~~~~~~~~

- Debug mode now uses a copy of locals() to prevent RuntimeError (`213 <https://github.com/pndurette/gTTS/issues/213>`_)

2.1.0

------------------

Features
~~~~~~~~

- The ``gtts`` module

- Added the ability to customize the Google Translate URL hostname.
 This is useful when ``google.com`` might be blocked within a network but
 a local or different Google host (e.g. ``google.cn``) is not
 (`143 <https://github.com/pndurette/gTTS/issues/143>`_, `203 <https://github.com/pndurette/gTTS/issues/203>`_):

 - New ``gTTS()`` parameter ``tld`` to specify the top-level
   domain to use for the Google hostname, i.e ``https://translate.google.<tld>``
   (default: ``com``).
 - Languages are also now fetched using the same customized hostname.

- Pre-generated TTS API request URLs can now be obtained instead of
 writing an ``mp3`` file to disk (for example to be used in an
 external program):

 - New ``get_urls()`` method returns the list of URLs generated by ``gTTS``,
   which can be used in lieu of ``write_to_fp()`` or ``save()``.

- The ``gtts-cli`` command-line tool

- New ``--tld`` option to match the new ``gtts`` customizable hostname (`200 <https://github.com/pndurette/gTTS/issues/200>`_, `207 <https://github.com/pndurette/gTTS/issues/207>`_)

- Other

- Added Python 3.8 support (`204 <https://github.com/pndurette/gTTS/issues/204>`_)


Bugfixes
~~~~~~~~

- Changed default word-for-word pre-processor (``('M.', 'Monsieur')``) which would substitute any 'm.' for 'monsieur' (e.g. 'them.' became 'themonsieur') (`197 <https://github.com/pndurette/gTTS/issues/197>`_)


Improved Documentation
~~~~~~~~~~~~~~~~~~~~~~

- Added examples for newer features (`205 <https://github.com/pndurette/gTTS/issues/205>`_, `207 <https://github.com/pndurette/gTTS/issues/207>`_)
