[470859] Complete release note and documentation

Remove the capability to cancel resize propagation on
RegionContainer resize as this is correctly managed from Region
and this produced unwanted side effects for Region which are also
RegionContainers.

Add a Warning validation rule to detect reconnect tools on edge mapping
related to Regions as the reconnect is disabled On Regions.

+h4. Compartments
+
+The resize of compartments might evolve in future versions. The current behavior is to redistribute space between adjacent compartments and to resize the first/last compartment when the compartmented container is resized from top/bottom for a vertical stack and left/right for an horizontal one.
+
+When resizing a compartmented container or a compartment from the top or from the left, the F3 shortcut configures the same behaviors than on standard containers (see previous section). 
+
+On _experimental_ structures of containers with compartmented compartments, the F3 shortcut also allows to disable the resize propagation to manually correct the computed layout and remove empty space (_experimental_). This might occur when there are several levels of compartments without the same number of compartments on each level. The corrective resize can be done on the last compartments of each compartmented container (from bottom for vertical stacks and from right for horizontal stacks).

+h4. Collapsing compartments
+
+When working with compartmented containers, you may want to collapse the compartments. Select a compartment and collapse/expand it using the handle visible on the following illustration. The collapse handle's location varies depending on the label alignment to avoid overlapping (depending on the list elements alignment for a list with an hidden label).
