In this release, we added the first support for subgraphs which are custom nodes created by extracting a small part of a graph and designating inputs and outputs.

• Added subgraph, simply search for Subgraph in the node search or node explorer, or select several nodes which you wish to convert to a custom node and press CTRL+G (by default)
• Added tooltips in rendered window
• Added a new "System info" node
• Binary operation, Unary operation, and Comparison now show its selected operation in the Node view directly.
• Visually tweak a popup menu in the Graph and Sources panel
• Edges now have a hover effect
• The ISO date is now written into a project savefile
• Control nodes can now be added to the Sources panel, simply right-click in the sources panel and select one of the Control items. Add a control node also to a graph and in its properties change "Control type" to "Group", your node now acts as a receiver of the Sources panel control.
