Release 6.13/02 - 2018-03-20

Highlights

  • LZ4 is now the default compression format, accelerating reading by factors; see e.g. this presentation
  • New graphics style “ATLAS" - thanks, ATLAS!
  • Auto-coloring for TF1 (drawing options PFC, PLC and PMC)
  • New color palette “cividis” compatible with color vision deficiency
  • Memory footprint reduction and a faster ROOT due to reduced reading of its PCH
  • Improved performance of parallelised operations - thread safety has been enhanced with a read-write lock, also reducing contention during gROOT and TObject destructions.
  • I/O support for std::vector with custom allocator.
  • C++17 support: you can enable it with the "-Dcxx17=ON" cmake option
  • Added templated version TBuffer::WriteObject
  • Implement reading of objects data from JSON; new TBufferJSON::ToJSON() and TBufferJSON::FromJSON() methods
  • New ROOT::Experimental::TVec allows to spell operations on vector elements without loops, also in TDataFrame
