@ -31,6 +31,11 @@ Bug Fixes
* `hy2py` can now handle format strings.
* Fixed crashes from inaccessible history files.
Misc. Improvements
------------------------------
* Drop the use of the long-abandoned `clint <https://github.com/kennethreitz/clint>`_ library
for colors. `colorama <https://github.com/tartley/colorama>`_ is now used instead.
0.17.0

@ -44,9 +44,9 @@ If this is causing issues,
it can be turned off globally by setting ``hy.models.PRETTY`` to ``False``,
or temporarily by using the ``hy.models.pretty`` context manager.
Hy also attempts to color pretty reprs using ``clint.textui.colored``.
This module has a flag to disable coloring,
and a method ``clean`` to strip colored strings of their color tags.
Hy also attempts to color pretty reprs and errors using ``colorama``. These can
be turned off globally by setting ``hy.models.COLORED`` and ``hy.errors.COLORED``,
respectively, to ``False``.
