Versions and changelog

Versions#

The specification is published one version at a time. This site carries version 0.5.1-draft, dated 2026-10-18, and the specification page names it at the top.

The source of every version is in the Common Agent Standards repository, where each version is tagged as mandate-v followed by the version. A tagged version is also kept at an address of its own: 0.4.1-draft, 0.4.2-draft, 0.5.0-draft, 0.5.1-draft. The main branch, which can be ahead of the published version, is rendered at agentmandate.net/draft/.

Versions 0.1.0-draft to 0.3.0-draft were written before the standard moved into the Common Agent Standards repository. The notes at the end of the specification say what 0.1.0-draft, 0.2.0-draft and 0.3.0-draft each changed.

Changelog#

The changelog is part of the standard's source and is reproduced here in full, newest first.

0.5.1-draft (2026-10-18)

Editorial, with no normative change. §8 says that the bookkeeper is a role described in Agent Roles, which is a guide of working descriptions, where it said a role defined at agentroles.ai. No requirement, field or section number changes.

0.5.0-draft (2026-10-18)

Who may sign an Agent NDA for an organization. A new power, nda, covers every act on an Agent NDA for the organization: signing an offer or an open offer, countersigning or accepting, joining a multilateral agreement, amending, terminating, and withdrawing (§6 rule 4). A new section, §7.2, states the check. When a seat carries organization, its signature record carries mandate, and that mandate holds nda. Checks 1 to 3 of §7 apply. Checks 4 and 5 do not, because an Agent NDA commits no price and names no offering. A mandate MAY carry scope.nda_categories, a list of Agent NDA §5.4 categories that narrows the power (§6 rule 8), and a sub-mandate narrows it as it narrows the rest of its scope (§6 rule 3). The check is enforced where a platform or a board holds the act pending and refuses on failure, and evidence elsewhere. A board releasing a gated Agent RFP body SHOULD run it on the recipient seat. A seat with no organization needs no mandate. §4, §7 check 3 and §10 name the new pieces, and the example mandate of §6 holds nda. The minor version moves because the change adds a power and a field.

0.4.2-draft (2026-10-18)

Editorial, with no normative change. The Agent Reputations entry of §10 said an organization's evidence aggregates at the entity, which Agent Reputations did not define until its 0.4.0-draft. It names the organization report of Agent Reputations §8.5, which groups the records of the organization's agents by anchor and by mandate membership (§9), and says that each agent keeps its own record. No requirement, field, example, or section number changes.

0.4.1-draft (2026-10-18)

Editorial, with no normative change. The specification names no platform: Agent Messaging is no longer given a former name, and "the mesh" reads "the network". The missing version note for 0.4.0-draft (2026-09-01), the check at a resource proxy of §7.1, is restored to the specification, and the date of 0.4.0-draft below is corrected to match it. No requirement, field, example, or section number changes.

0.4.0-draft (2026-09-01)

The first version tagged in the Common Agent Standards repository, as mandate-v0.4.0-draft. The site of the standard showed 0.3 while the specification read 0.4.0-draft. The version here is the specification's, 0.4.0-draft.
