Highlights ROOT v6.18/00 is a consolidation release with many performance improvements! Its more than 2000 commits since v6.16/00 also introduce several new features: A new builtin zlib library that's based on CMS's fork of the Cloudflare ... [More] implementation. It noticeably accelerates decompression on current CPUs. A simple auto obj = dir->Get("some object"); (where dir can be a file) Pythonizations for RDataFrame providing AsNumPy New leaf types /f, /d for Float16_t and Double32_t: tree->Branch("floatArray", floatArray, "floatArray[7]/f[0,100]"); // Float16_t array with range from 0 to 100 Several new functions for RVec, e.g. DeltaR The RooJohnson PDF was added to RooFit Considerably faster, STL-style iteration through RooArgSet and RooArgList Transparency for lines, texts and markers in the TeX output. Many new features in JSROOT, including initial WebVR support thanks to Diego Marcos (get your Cardboards ready!) Added support for GCC9, macos 10.15 (Catalina beta 2) and Xcode 11.0 beta If you build against ROOT using its CMake infrastructure you might be interested in the changes to ROOT_GENERATE_DICTIONARY and ROOT_STANDARD_LIBRARY_PACKAGE. For this and what else is new please have a look at the release notes! Release Notes The release notes for this release can be found here.

Its more than 2000 commits since v6.16/00 also introduce several new features: A new builtin zlib library that's based on CMS's fork of the Cloudflare ... [More] implementation. It noticeably accelerates decompression on current CPUs. A simple auto obj = dir->Get("some object"); (where dir can be a file) Pythonizations for RDataFrame providing AsNumPy New leaf types /f, /d for Float16_t and Double32_t: tree->Branch("floatArray", floatArray, "floatArray[7]/f[0,100]"); // Float16_t array with range from 0 to 100 Several new functions for RVec, e.g. DeltaR The RooJohnson PDF was added to RooFit Considerably faster, STL-style iteration through RooArgSet and RooArgList Transparency for lines, texts and markers in the TeX output. Many new features in JSROOT, including initial WebVR support thanks to Diego Marcos (get your Cardboards ready!) Added support for GCC9, macos 10.15 (Catalina beta 2) and Xcode 11.0 beta If you build against ROOT using its CMake infrastructure you might be interested in the changes to ROOT_GENERATE_DICTIONARY and ROOT_STANDARD_LIBRARY_PACKAGE. For this and what else is new please have a look at the release notes! Release Notes The release notes for this release can be found here.

We offer two packaging types: exe: a regular Windows installer package also setting up the required environment variables. With uninstall via "Control Panel" / "Add or Remove Programs". Simply download and start, or open directly. You can double-click ROOT to start it, ROOT files get registered with Windows. tar: the traditional variant. Unpack e.g. with 7zip. Start ROOT in a Microsoft Visual Studio Prompt (in Start / Programs / Microsoft Visual Studio / Tools). If you installed ROOT to C:\root then call C:\root\bin\thisroot.bat before using ROOT to set up required environment variables. Important installation notes You must download the binary built with the exact same version of Visual Studio as the one installed on your system. Do not untar in a directory with a name containing blank characters. Take the release version if performance matters.

Milosz Blaszkiewicz and Aleksandra Mnich (AGH University of Science and Technology - Poland) wanted to evaluate a set of Big Data tools for the analysis of the data from the TOTEM experiment which will enable interactive or semi-interactive work with ... [More] large amounts of data. They ended up re-implementing a full Totem analysis in a declarative fashion using RDataFrame and distributing their calculations over a big Spark cluster with PyRDF. Check it out on CDS!   [Less]

ROOT's main test suite roottest has several tests that still use GNU-Makefiles. For Windows, to ease maintenance, and to get rid of a legacy tool called rmkdepend we need to transform them to CMake. Start with a simple one, e.g. ... [More] root/tree/string/Makefile! Expected Results Less GNU-Makefiles, more consistent / complete CMake-based setup. Requirements Basic CMake and GNU make knowledge; there is nothing ROOT specific. [Less]

ROOT's binaries understand a mixture of short and long arguments. The parsing is done in C++, with ad hoc C++ code. We would like to switch to a C++ command line argument library. This would imply implementing ROOT's options (e.g. in ... [More] TApplication.cxx and rootcling_impl.cxx) using that library. Expected Results ROOT's command line arguments are parsed with a C++ library; we can combine arguments: root -lbq tutorials/hsimple.C Requirements Basic C++ knowledge; there is nothing ROOT specific.
