Exo 0.11.3 Released

Xfce 4.14 development has been picking up steam in the past few months. With the release of Exo 0.11.3, things will only get steamier.

What is Exo?

Exo is an Xfce library for application development. It was introduced years ago to aid the development of Xfce applications. Although it’s not used quite as heavily these days, you’ll still find Exo components in Thunar (the file manager) and the Xfce Settings Manager.

Exo provides custom widgets and APIs that extend the functionality of GLib and GTK+ (both 2 and 3).  It also provides the mechanisms for defining preferred applications in Xfce.

What’s New in Exo 0.11.3?

New Features

  • exo-csource: Added a new --output flag to write the generated output to a file (Xfce #12901)
  • exo-helper: Added a new --query flag to determine the preferred application (Xfce #8579)

Build Changes

  • Build requirements were updated.  Exo now requires GTK+ 2.24, GTK 3.20, GLib 2.42, and libxfce4ui 4.12
  • Building GTK+ 3 libraries is no longer optional
  • The default debug setting is now “yes” instead of “full.” This means that builds will not fail if there are deprecated GTK+ symbols (and there are plenty).

Bug Fixes

  • Discard preferred application selection if the dialog is canceled (Xfce #8802)
  • Do not ship generic category icons; these are standard (Xfce #9992)
  • Do not abort builds due to deprecated declarations (Xfce #11556)
  • Fix crash in Thunar on selection change after directory change (Xfce #13238)
  • Fix crash in exo-helper-1 from GTK 3 migration (Xfce #13374)
  • Fix ExoIconView being unable to decrease its size (Xfce #13402)
