libxkbcommon 0.7.1 - 2017-01-18
==================

- Fixed various reported problems when the current locale is tr_TR.UTF-8.

  The function xkb_keysym_from_name() used to perform case-insensitive
  string comparisons in a locale-dependent way, but required it to to
  work as in the C/ASCII locale (the so called "Turkish i problem").

  The function is now no longer affected by the current locale.

- Fixed compilation in NetBSD.
