The download is here and the full changelog is here.

Changes of note:

• New options dialog.
• Now you can recapture the last selected area again without redrawing a rectangle or reselecting a window.
• New hotkey system with all “instant-capture” buttons.
• New overlay shows a window’s title and highlights the capture area.  It also performs a slight bit better (CPU usage is still a bit high when moving the mouse around when capturing a window, unfortunately).
• New capture option that can capture windows being overlayed by other windows.  However it will probably only work best with programs using normal controls; custom controls have to “opt-in” to support the API (WM_PRINTCLIENT message) otherwise it won’t render properly.  Even the desktop (essencially a custom-painted listview) doesn’t render the wallpaper or background color.  Because of these limitations this option is off by default.
