          - rust default stable version (\`ci/rust-toolchain-stable.toml\`)
          - rust default nightly version (\`ci/rust-toolchain-nightly.toml\`)
          - python version for the python lint (\`.github/workflows/lint.yml\`)
          - tor and tgen versions for the tor tests (\`.github/workflows/extra_tests.yml\`)
          - versions of github actions (\`uses: <action-name@version>\` in \`.github/workflows/*.yml\`)

          Shadow's dependencies may also need to be updated.

          \`\`\`bash
          # The cargo \`upgrade\` subcommand requires \`cargo install cargo-edit\`. \`cargo upgrade\`
          # won't update the lock file for all dependencies, so \`cargo update\` is also needed.
          cd src && cargo upgrade --incompatible && cargo update
          \`\`\`
