When modifying an existing feature under features/src/<feature>/, increment the patch component of that feature's devcontainer-feature.json version in the same pull request. Increment it once per feature per pull request, regardless of how many files or commits modify the feature.
Before selecting the new version, bring the working branch up to date with the pull request's target branch (for example, main or release/*) and increment from the version currently on that target branch, not from the working branch's original base.
