Version 1.6

• Fix portability issues with signed vs unsigned chars in the config file parser (thanks to Charlène Wendling).
• The -t option now allows fractional time values (e.g. -t 0.5 to display for half a second).
• Set window type hint to notification to avoid shadows and other decorations (thanks to Markus Demleitner).
• Add support for right-to-left text (thanks to @ilevi-code).

Version 1.5.1

• Fix black squares around cow and bubble on non-compositing window manager.

Version 1.5

• Updated from Gtk2/GDK to Gtk3/Cairo. Note that because of the removal
  of the `gtk_widget_shape_combine_mask' API that xcowsay used for
  transparency, we now rely on the alpha channel of the window and a
  compositing window manager for this.
• As a side effect of this, the bubble is now anti-aliased, fixing a
  long-standing issue.
• Unfortunately running xcowsay without a compositor is no longer
  supported. If this affects you please continue to use 1.4 as there are
  no functional changes in 1.5.
• The cow position is more random (thanks to Tony Finch).

Version 1.4

• Fixed various usages of deprecated Gtk features
• Allow values with quotes to be set in the config file
• Fixed a crash when the -r option was used without a value
• Added a --release option to close the window on mouse button release
