Release 6.30.04 - 2024-01-31


This patch release of the 6.30 branch not only features a few bug fixes, but rather remarkable runtime performance optimizations. The memory footprint of the plugin manager has been reduced. Moreover, the mechanism by which symbols are looked up by the interpreter was improved, avoiding to open and close a large number of libraries at startup, which improves considerably the user experience as well as cpu efficiency on batch jobs. More verbose output is now provided if wrong settings are used for the web-based widgets, the usage of the loopback device is enforced and only one connection is allowed to RBrowser.

Installations in CVMFS

Standalone installations with minimal external dependencies are available at:



The entire ROOT source can be obtained from our public Git repository:

git clone

The release specific tag can be obtained using:

cd root
git checkout -b v6-30-04 v6-30-04

See instructions to build from source.


Windows 10/7/… are supported. 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. You can double-click ROOT to run it; ROOT files get registered with Windows.
  • tar: 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 than 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.
  • If you want to debug your code you need the ROOT debug build (you cannot mix release / debug builds due to a Microsoft restriction).
