In this release we have fixed a bug in rich:chart that prevented displaying sparse data sets and fixed a problem with nested elements inside rich:autocomplete (such as rich:placeholder). A "default node" functionality has been added to rich:tree, consult the showcase example to see how it works (part of this feature was already in place but largely undocumented).
[RF-10642] - Autocomplete does not have a title attribute
[RF-11327] - Inplace Input - typing a space into the input field
[RF-14205] - rich:chart does not render sparse datasets
[RF-14206] - fileUpload: custom progressBar is not used
