No new ordinance shall be construed to repeal a former ordinance as to any offense committed against a former ordinance, nor as to any act done, or penalty, forfeiture or punishment incurred, or any right accrued or claim arising under the former ordinance or, in any way whatever, to affect any offense or act so committed or done, or any penalty, forfeiture or punishment so incurred, or any right accrued or claim arising before the new ordinance takes effect; except that, the proceedings thereafter shall conform, so far as practicable, to the laws in force at the time of the proceedings. If any penalty, forfeiture or punishment is mitigated by any provision of the new ordinance, the provision may, by the consent of the party affected, be applied to any judgment pronounced after the new ordinance takes effect.
