 ### RDataFrame
 
 - With [ROOT-10023](https://sft.its.cern.ch/jira/browse/ROOT-10023) fixed, RDataFrame can now read and write certain branches containing unsplit objects, i.e. TBranchObjects. More information is available at [ROOT-10022](https://sft.its.cern.ch/jira/browse/ROOT-10022).
 - Snapshot now respects the basket size and split level of the original branch when copying branches to a new TTree.
 - For some `TTrees`, RDataFrame's `GetColumnNames` method returns multiple valid spellings for a given column. For example, leaf `"l"` under branch `"b"` might now be mentioned as `"l"` as well as `"b.l"`, while only one of the two spellings might have been recognized before.
