Release notes for 0.5.0
=======================

This is a development release leading up to exo 0.6.0. The new API
additions are not yet finalized, so there may be incompatibilities
between this release and the final 0.6.0 release.

The API version of exo has been changed from 0.3 to 1, to make it easier
to bump minor and major version numbers in future releases. To compile
against this version of exo, you have to change exo-0.3 to exo-1 in your
configure file. This backwards-incompatible change has also been used to
remove deprecated APIs or APIs that are now provided by Gtk 2.14 or Glib
2.18.

Removed or incompatibly changed classes/enums/functions:
  - Renamed exo_url_about_dialog_hook() to
    exo_gtk_url_about_dialog_hook().
  - Exo(Mutual)Binding structures are now private.
  - Removed exo_icon_view_{set,get}_{text,markup,pixbuf}_column().
  - Removed ExoPangoEllipsizeMode and related functions.
  - Removed exo_md5_*() functions and ExoMd5Digest.
  - Removed exo_intern_string() and exo_intern_static_string().
  - Removed ExoEllipsizedLabel has been entirely removed.
  - Removed exo_gtk_object_ref_sink() and
    exo_gtk_radio_action_set_current_value().
  - Removed exo_url_show() and exo_url_show_on_screen().

New classes/functions:
  - ExoJob and ExoSimpleJob for handling threaded/asynchronous jobs.
  - exo_str_is_empty(), exo_str_looks_like_an_uri().

Other changes:
- GIO module for handling URIs that are known by the preferred
  applications framework.
- API documentation has been inlined in the code.
- Various other fixes, cleanups and translation updates.
