Git Methodology#

This page defines the canonical branch model used for CCCL development and release maintenance.

Canonical branches#

  • main

  • branch/X.Y.x

    • Branches from main meant for stabilizing and publishing tagged releases.

    • Created via release automation.

    • Changes should be made via the backport process.

  • ctk/X.Y.x

    • Branches from branch/X.Y.x meant for representing exact contents of CUDA Toolkit Releases

    • Created by NVIDIA. May contain internally developed features that are additive with the release it was based on.

    • This is a read-only branch and is created when the CTK or relevant documentation becomes available.

Tagging conventions#

  • vX.Y.Z: finalized release tags on release branches

  • vX.Y.Z-ctkN.M.K: finalized release tags exactly equivalent to the CCCL contents in NVIDIA CUDA Toolkit release N.M.K.

  • vX.Y.Z-rcN: release-candidate tags for pre-release validation.

  • vX.Y.Z.dev: the first commit of development for X.Y.Z (the commit that increments the library version)
