DOI

Release v0.31.0 is out of the oven.

This release contains no major API breakage, but all around improvements and bug fixes.

This release drops support for Go-1.16 (and earlier).

groot

  • bump to ROOT-6.26/00
  • implement a riofs Reader over HTTP(s), instead of downloading the whole file locally
  • improve performances of rcmd.Dump(tree)
  • add support for TMultiGraph
  • add support for TDatime
  • add support for TGraphMultiErrors
  • add support for TProfile{,2D}
  • add support for TEfficiency
  • add support for TConfidenceLevel, TLimit{,DataSource}
  • add support for TF1 and TFormula
  • add support for reading std::vector<T, myalloc<T>>
  • introduced a new package groot/rnpy, to ease ROOT/NumPy conversions (like groot/rarrow does for Arrow)
  • improve memory usage of root2npy, by materializing into memory only one column at a time
  • streamline C++ templates parsing for STL containers (vector,deque,map,unordered_{,multi}{map,set}, pair, ...)

xrootd

  • improve the read performances 10-fold, using a finer-grained lock to protect session IDs

AOB

That's all for today.
Last release we said there would probably be some work on the RNTuple front.
We didn't lie, but this didn't happen in the form we thought it would.
A surprise is in the works... stay tuned.

Next cycle will probably see some work on the RNTuple front, and that work appear in main.
