| 3 | +apply-release-changes.py - Cross-platform script to replace main with a specified release version in YML files |
| 4 | +
|
| 5 | +This script performs two replacements in YML files in .github/workflows/: |
| 6 | +1. Replaces @main with @release/VERSION |
| 7 | +2. Replaces 'test-infra-ref: main' with 'test-infra-ref: release/VERSION' |
| 8 | +
|

| 10 | + python apply-release-changes.py VERSION |

| 13 | + python apply-release-changes.py 2.7 |
