1. Run the script:

   python scripts/release/bump_sglang_version.py 0.5.4rc0
   

2. Verify changes with git diff:

   git diff
   

3. Check specific files contain the new version:

   grep -r "0.5.4rc0" python/sglang/version.py
   grep -r "0.5.4rc0" python/pyproject.toml
   grep -r "0.5.4rc0" docs/get_started/install.md
   

4. Reset changes (if testing):

   git checkout .
   

Test Kernel Version Bump

1. Run the script:

   python scripts/release/bump_kernel_version.py 0.3.13
   

2. Verify changes with git diff:

   git diff
   

3. Check specific files contain the new version:

   grep -r "0.3.13" sgl-kernel/python/sgl_kernel/version.py
   grep -r "0.3.13" sgl-kernel/pyproject.toml

Version Format Validation

• SGLang versions: X.Y.Z or X.Y.ZrcN (e.g., 0.5.3 or 0.5.3rc0)
• Kernel versions: X.Y.Z (e.g., 0.3.12)

The scripts will validate the version format and exit with an error if invalid.
