                   GNU Image Manipulation Program
                          Development Branch
                   ------------------------------

This is the unstable development branch of GIMP. Here we are working
towards the next stable release, which will be GIMP 2.10.

Generally, all bug fixes that are applied on the stable GIMP 2.8
branch are also applied here, but they are usually not mentioned
in NEWS.

Overview of Changes from GIMP 2.9.4 to GIMP 2.9.6
=================================================

Core:

  - New clipboard implementation allows copying/pasting layers and 
    layer groups
  - Color tags simplify managing large projects with a lot of layers 
    and layer groups

    color-managed now

GUI:

  - Easily add or remove layer masks by clicking either the layer 
    preview or a new button in the Layers dialog
  - Enhance the Layer Attributes dialog to provide the single UI for 
    setting layer's name, blending mode, opacity, and offset, 
    toggling visibility, link status, various locks, color tags.
  - Add a Save As button to the “Quit GIMP” dialog
  - Allow to choose fill color when resizing layers and images
  - Quick Mask and Channel Attributes dialogs use the new spinscale
    widget for the  mask opacity slider
  - Enable grid views of dynamics and tool presets
  - Many new icons

Configurability:

  - Remember settings of many dialogs across sessions
  - New Interface / Dialog Defaults page in the Preferences dialog to 
    control defaults values of various dialogs
  - Settings on some individual pages of the Preferences dialog can be
    reset separately now
  - Vertical scrollbar added to keep the height of the Preferences 
    dialog fitting small displays
  - Allow mouse to optionally configure tablet devices

Tools:

  - The Move tool now shows relative coordinates when moving guides 
    and sample points

    spaces other than sRGB now
  - Uncommitted selection by the Intelligent Scissors tool is not 
    discarded on tool change anymore.
