+
+== 1.6.1
+
+* Fixed raw_no_echo_mode so that it uses stty -icanon rather than cbreak

+  HighLine was silently swallowing error messages when ffi-ncurses gem
+  was installed without ncurses present on the system.

+  is the only way we could find to restore HighLine's character reading to

+  key can be used in a new question.
+* Added File support to HighLine.ask().  You can specify a _directory_ and a
+  _glob_ pattern that combine into a list of file choices the user can select
+  from.  You can choose to receive the user's answer as an open filehandle or as
+  a Pathname object.

+  loaded.
+* Improved "stty" state restoring code.
+* Fixed "stty" code to handle interrupt signals.

+  through the +responses+ interface as <tt>:no_completion</tt>.
+
+== 0.5.0
+
+* Implemented <tt>echo = false</tt> for HighLine::Question objects, primarily to
+  make fetching passwords trivial.
+* Fixed an auto-complete bug that could cause a crash when the user gave an
