3.10.0

uproot can now write TTrees containing baskets with flat data!

Example -

import uproot
filename = "example.root"

b = uproot.newbranch(">i4", compression=uproot.LZMA(3))
branchdict = {"intBranch": b}
tree = uproot.newtree(branchdict)
a = [1, 2, 3, 4, 5]
with uproot.recreate(filename, compression=uproot.ZLIB(4)) as f:
     f["t"] = tree
     f["t"]["intBranch"].newbasket(a)

3.9.3

Adds TRefArray (PR #330), in addition to just TRef (PR #326).
