ROOT enables statistically sound scientific analyses and
visualization of large amounts of data: today, more than 1 exabyte
(1,000,000,000 gigabyte) are stored in ROOT files. The Higgs was
found with ROOT!

*.*

As high-performance software, ROOT is written mainly in C++. You can
use it on Linux, macOS, or Windows; it works out of the box. ROOT is
open source: use it freely, modify it, contribute to it!

ROOT comes with an incredible C++ interpreter, ideal for fast
prototyping. Don't like C++? ROOT integrates super-smoothly with
Python thanks to its unique dynamic and powerful Python = C++ binding
. Or what about using ROOT in a Jupyter notebook?

RNTuple: Where are we now and what's next? (26 Jan
2024)

Hello, this is Florine from the ROOT team! Over the
past year, I've been working as a technical student
funded by ATLAS to evaluate and help further develop
RNTuple. As you may already be aware, RNTuple [1] is
currently being developed as the successor to TTree,    Latest
and is projected to be used in Run 4. I imagine you     Releases
might be wondering why there is a need for a
completely new (TTree-incompatible) system, and what
this looks like. That's why in this blog post, I will     * Release
try to answer this question, as well as give you an         6.32/00 -
overview of the current status of RNTuple, what we're       28th of
still working on before its first production release        May, 2024
(and what we will work on beyond this), and finally       * Release
how you can already try it out!                             6.30.06 -
