+    Rebuild for CUDA 12
+    
+    The transition to CUDA 12 SDK includes new packages for all CUDA libraries and
+    build tools. Notably, the cudatoolkit package no longer exists, and packages
+    should depend directly on the specific CUDA libraries (libblas, libcusolver,
+    etc) as needed. For an in-depth overview of the changes and to report problems
+    [see this issue]( https://github.com/conda-forge/conda-forge.github.io/issues/1963 ).
+    Please feel free to raise any issues encountered there. Thank you! :pray:

+  summary: |
+    Scalable, Portable and Distributed Gradient Boosting (GBDT, GBRT or GBM) Library, for
+    Python, R, Java, Scala, C++ and more. Runs on single machine, Hadoop, Spark, Flink
+    and DataFlow
+  description: |
+    XGBoost is an optimized distributed gradient boosting library designed to be highly efficient,
+    flexible and portable. It implements machine learning algorithms under the Gradient Boosting
+    framework. XGBoost provides a parallel tree boosting (also known as GBDT, GBM) that solve many
+    data science problems in a fast and accurate way. The same code runs on major distributed
+    environment (Hadoop, SGE, MPI) and can solve problems beyond billions of examples.
