Release (2014-11-10)

New Features:

Navigate around filter graph using keyboard. Arrow keys navigate between filters, control-arrow navigates between pins, shift key extends the selection. Newly created filters are connected to the currently selected output pin. Escape key to clear filter and pin selection. Shift F10 or menu key for context menu. Enter or Alt Enter for properties. Delete or Backspace to delete filter(s) or disconnect pin(s). Shift Delete or Backspace to disconnect filter(s). ( issue #217 , # issue 252 , issue #254 )
Connect pin offers popup menu of available target pins to connect to. If selected pin already connected, reconnect with the same media type (or use intelligent or choose media type modes if enabled). If two filters are selected, connect the filters together via the first available pins. ( issue #222 , issue #249 )
XML files now saved under new .grfx extension. .grfx file extension is registered with Windows ( issue #152 )
Preview and filter DbgLog file output in property page (NB DbgLog works in debug filter builds ONLY). Also configure registry settings for DbgLog. ( issue #61 )
Better support for creating filters directly from DLLs instead of CoCreateInstance. Scan for CLSIDs implemented by DLL, create the filter from the same DLL when graph is saved to .grfx file and reloaded (impossible to support this for .grf files though). DLLs appear on the File menu as recently used files (but don't clear the existing graph when 'opened'). Property pages are created directly from filters DLL class factory with fallback to creating via CoCreateInstance. Can be used to run two different versions of the same filter side by side in a single graph. ( issue #31 )
Disconnect selected filters ( issue #236 )
Show H.265/HEVC decoder specific configuration ( issue #242 )
Show streaming progress in windows 7 taskbar (issue #18)
