IOBox (String) now has 'open' button in Filename, Directory and URL setting
GetElements (XML ByName) supports prefixed names now (prefix:name) and if no prefix given, will use default namespace of given XElement.
Mouse (Window/Global) output state of XButton1 and XButton2
KeyMatch (String) node will also check for characters now (not keys only)
added new input pin "Validation" to AsElement (XML) node in order to enable DTD or Schema validation - by default validation is off, but in some cases (like parsing v4p files) validation is needed as the DTD file defines new entities
"Boygroup (Server) Enabled"-Pin only enables/disables bridge broadcast messages. other messages are always sent (e.g. patch messages)
Prune (XML) is now named Prune (XElement) and supports generating text and children in addition to attribute output pins. Root element is now defined by XPath expression. Patches using the old version of Prune will need revision.
renamed BufferedIOStream to MemoryIOStream - same naming scheme as .NET streams
new property IHDEHost.IsRunningInBackground
IOFactory can create in-place plugins now - for example look here
new interface IUserInputWindow which gets used by Mouse (System Window) in order to properly subclass a plugin's window
new property AllowFeedback on output plugin pins - see dx11-feedback for usage example
added basic support for future packs:
add packs/PACKNAME/core to assembly search path
add packs/PACKNAME/factories to mef container catalog on startup
