The <jats:italic>International Code of Nomenclature for algae, fungi, and plants<\/jats:italic>, of which the most recently published edition is the <jats:italic>Shenzhen Code<\/jats:italic> of 2018, provides this system for algae, fungi, and plants. This <jats:italic>Code<\/jats:italic> is regularly revised at an International Botanical Congress (IBC), usually held every 6 years, most recently in Madrid, Spain, in July 2024. The Madrid IBC amended the <jats:italic>Shenzhen Code<\/jats:italic>, and the changes took effect on 27 July 2024, when the closing plenary session of the IBC approved the decisions of the Nomenclature Section. It is important to promptly publicize this information because the new edition of the <jats:italic>Code<\/jats:italic> resulting from these amendments, the <jats:italic>Madrid Code<\/jats:italic>, will not be published until mid\u20102025.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>I selected some of the more important of the 433 published proposals to amend the <jats:italic>Code<\/jats:italic> at the Madrid IBC.
