|

|

In the previous version, XGBoost statically linked NCCL, which significantly increased the binary size and led to hitting the PyPI repository limit. With the new release, we have made a significant improvement. The new release can now dynamically load NCCL from an external source, reducing the binary size. For the PyPI package, the ``nvidia-nccl-cu12`` package will be fetched during installation. With more downstream packages reusing NCCL, we expect the user environments to be slimmer in the future as well. (#9796, #9804, #10447)

***************************************************
|
||||
Parts of the Python package now require glibc 2.28+
|
||||
***************************************************
|
||||
Starting from 2.1.0, XGBoost Python package will be distributed in two variants:
|
||||
|
||||
* ``manylinux_2_28``: for recent Linux distros with glibc 2.28 or newer. This variant comes with all features enabled.
|
||||
* ``manylinux2014``: for old Linux distros with glibc older than 2.28. This variant does not support GPU algorithms or federated learning.
|
||||
|
||||
The ``pip`` package manager will automatically choose the correct variant depending on your system.
|
||||
|
||||
Starting from **May 31, 2025**, we will stop distributing the ``manylinux2014`` variant and exclusively
|
||||
distribute the ``manylinux_2_28`` variant. We made this decision so that our CI/CD pipeline won't have
|
||||
depend on software components that reached end-of-life (such as CentOS 7). We strongly encourage
|
||||
everyone to migrate to recent Linux distros in order to use future versions of XGBoost.
|
||||
|
||||
Note. If you want to use GPU algorithms or federated learning on an older Linux distro, you have
|
||||
two alternatives:
|
||||
|
||||
1. Upgrade to a recent Linux distro with glibc 2.28+. OR
|
||||
2. Build XGBoost from the source.
