I'm very pleased to announce releases for the main three projects that i'm working on:

• Release 4.0 of Substance look-and-feel (code-named Key Largo)
• Release 3.1 of Laf-Widget layer for LAFs (code-named Edelweiss)
• Release 2.0 of Flamingo component suite (code-named Caireann)

• Six new skins: Nebula, Nebula Brick Wall, Autumn, Magma, Mist Silver and Mist Aqua.
  
• State-aware theme transitions
• Smart tree scroll
• Glowing icons (buttons, option pane)
• Support for JXPanel translucency
• SwingX UI delegates in SwingX plugin
  
• Border painters
• New title painters: Brushed Metal, Marble Noise
  

Some applications may need to follow the instructions in the migration guide. The latest stable NetBeans module available here installs Substance as the look-and-feel in NetBeans 6.0 and allows playing with various skins, themes and watermarks.

Work has begun on the next releases, Lima for Substance, Foxglove for Laf-Widget and Deirdre for Flamingo.
