We’ve unlocked game-changing capabilities, including the ability to opt-out of automatic class registration, experimental access to high-performance, multithreading-optimized histograms, and a sleek, ergonomic new file interface (RFile) designed for modern workflows. + +But we didn't stop there. We’ve streamlined the entire codebase for peak efficiency and addressed over 160 items in our trackers to ensure rock-solid stability and cutting-edge features ([see the full list here](https://root.cern/doc/v640/release-notes.html#items-addressed-for-this-release)). Dive into the full [release notes](https://root.cern/doc/v640/release-notes.html) and explore the highlights below! + +🔓**Opt-out of automatic class registration** Break free from histograms and objects automatically attaching to the current (T)directory! Enable this game-changing capability invoking ROOT::Experimental::DisableObjectAutoRegistration(): unlock more control by [exploring the documentation](https://root.cern.ch/doc/master/namespaceROOT_1_1Experimental.html#a74fae8f88965b8c79dfbd25bebbce3a4). +Histograms More features in the new histograms! Concurrent filling is now available, also to save memory in highly multithreaded applications. This feature is even integrated into RDataFrame: [check out the tutorials](https://root.cern/doc/v640/group__tutorial__histv7.html)! + +🤖 **Machine Learning** The Data Loader has been reimagined as ROOT::Experimental::ML::RDataLoader! This powerful tool now performs cluster-aligned reads with a sophisticated shuffling strategy and supports multiple RDataFrames as input. Seamlessly output to NumPy, PyTorch, or TensorFlow, while leveraging new under- and oversampling support for dual-class eager loading. + I/O Experience a brand-new, streamlined HTTP I/O implementation powered by [libcurl](https://curl.se/libcurl/)! This update delivers modern remote read capabilities, including advanced compression, secure transport, and S3 support, all across 🐧🍎🪟. + +🔀 **RNTuple** Multiple threads can share a single reader efficiently thanks to the “active entry tokens” added to the RNTupleReader: very useful for data processing frameworks! + +🌳 **Ready to evolve beyond TTree::Draw?** We’ve provided a comprehensive [Rosetta Stone](https://root.cern/doc/master/classROOT_1_1RDataFrame.html#rosetta-stone) to help you seamlessly transition to RDataFrame! This is the perfect path for high-performance RNTuple support or scaling your workflows across multithreaded and distributed environments. + +🚀 **RDataFrame analysis** By streamlining the memory ownership model and implementing a sophisticated sharing mechanism, RDataFrame now minimizes redundant just-in-time compilation across computation graphs. Experience faster setup times and a significant reduction in memory footprint within a single application! + +📦 **Builtins** We’ve dramatically streamlined our codebase. The builtin package footprints have been [slashed by a factor of 4x](https://root.cern/doc/v640/release-notes.html#moving-from-builtin-dependencies-to-system-provided-packages). This makes ROOT lighter and faster to build than ever, while pivoting toward a robust reliance on high-performance system packages. + + + +## Binary distributions +Instead of manually downloading this binary, please explore first whether your [package manager](../../install/#install-via-a-package-manager){:target="\_blank"} already provides this version. +This way, you will automatically keep up-to-date with the latest stable versions with no manual maintenance on your side. + +| Platform | Files | Size | +|-----------|-------|-----| +| Almalinux 8.10 |
