• Defaulting guardrails to null changes the API contract; confirm that consumers can handle missing guardrails and consider documenting the default behavior.

    val guardrails: GuardrailsHash? = null,

src/main/kotlin/io/newm/kogmios/protocols/model/GovernanceAction.kt:57

• Making ancestor optional could break existing clients expecting a non-null value; ensure this change is intentional and update documentation or API versioning if necessary.

    val ancestor: UtxoInput? = null,

buildSrc/src/main/kotlin/Versions.kt:15

• The removal of MAVEN_REPO_AUTH_PLUGIN and addition of MAVEN_PUBLISH suggests changes in publishing setup; verify that build scripts are updated and no plugin references are left dangling.

    const val MAVEN_PUBLISH = "0.34.0"

tests pass locally as they require an ogmios instance to run.
