Eye of GNOME

Revamped UI, in line with GNOME 3 design patterns:

  • Header bar.
  • Overlaid navigation and rotation controls.


  • Terminal now compresses and encrypts the scrollback buffer contents that are stored in a temporary file on disk.

What's new for administrators and distributors

  • The gnome-documents module now ships a second app, gnome-books. The recommendation is to package these two separately
  • dconf-editor is now a separate module, no longer part of dconf

What's new for developers


  • GObject instance counts for debugging: this helps for finding reference leaks. To use this facility, you have to set the GOBJECT_DEBUG=instance-count environment variable and can then use g_type_get_instance_count() to get the number of live objects of a given type at any time. GtkInspector has a UI for this

  • Better implementation of the existing GNetworkMonitor interface (using NetworkManager). It lets applications find out if they are connected to the internet, or just locally, or stuck behind a portal

  • GListModel: a GSequence-based object list. This is meant to be used as an alternative to GtkTreeModels when your data is already naturally organized in GObjects. GtkListBox has an api to use such models: gtk_list_box_bind_model

  • G_DECLARE_TYPE: Boilerplate-reducing macros. This takes much of the tedious typing (or copy-paste) out of creating a GObject from scratch (in C)
  • g_autoptr: Automatic cleanup for local variables (supported on gcc and clang). Another improvement for C programmers: automatic cleanup for local variables ("I can't believe its not C++")
  • GSimpleIOStream: Simple wrapper for construcing GIOStreams


  • OpenGL support
  • Mir backend
  • Many GtkInspector improvements:

    • Better layout
    • Memory tracking
    • Magnifier
    • Separate display connection
    • JavaScript repl

  • GtkPopoverMenu: New widget for creating popover menus manually

  • GtkGLArea: New widget for OpenGL rendering
  • Support for versioned themes
  • Better OS X support for app menus
  • Customizable selection behavior in GtkTextView


  • One tracker binary instead of several tools starting with 'tracker-'

    • Annotations fixes for various functions
    • Remove incorrect info about area-prepared signal

    • Flag multi-page TIFF files
    • Fix memory usage for GIF animations, add note about minimum frame length
    • Return an error for truncated PNG files
    • Add density (DPI) support for JPEG, PNG and TIFF
    • Fix reading CMYK JPEG files generated by Photoshop
    • Allow saving 1-bit mono TIFF files as used in faxes

GNOME MultiWriter

MultiWriter can be used to write an ISO file to multiple USB devices at once. MultiWriter may be useful for QA testing, to create a GNOME Live image for a code sprint or to create hundreds of LiveUSB drives for a trade show.

Screenshots available here: https://git.gnome.org/browse/gnome-multi-writer/tree/data/appdata

Plans for GNOME 3.18

  • gnome-2048: A number game (unlikely to be ready for 3.16)
  • GNOME Control Center can optionally use an Ambient Light Sensor to control the backlight brightness. This usually saves a lot of battery power. (Screenshot available on request)
  • Complete Calendar application
