Changelog

All notable changes to this project will be documented in this file.

Repository releases and the specification version move on separate tracks; see VERSIONING_POLICY.md. The specification has remained manifest_version: 1.0 since [1.0].

[Unreleased]

Changed

Normalized author metadata in CITATION.cff to full legal name (“Hernán Alfredo Capucci”) for bibliographic consistency.
Configured CITATION.cff to use Zenodo v1.0 archived specification as the preferred citation target (DOI: 10.5281/zenodo.18833956).

[1.1.0] - 2026-03-12

Repository release. No changes to the normative specification (spec/v1.0/); manifest_version remains 1.0.

Added

Conceptual architecture diagram for the ecosystem (docs/architecture/agent-manifest-ecosystem.svg), referenced from README.md and docs/ARCHITECTURE.md.
Ecosystem mapping documentation (docs/ecosystem-map.md).
Registration guides: docs/how-to-register.md and docs/registration-demo.md.
Well-known discovery endpoint on the spec site (.well-known/agent-manifest-registry.json).
$schema references in all examples to improve editor validation.

Changed

Architecture documentation refinements and documentation structure improvements.

[1.0.0] - 2026-03-02

Zenodo trigger release for DOI registration. Content identical to [1.0] (zero commits between the v1.0 and v1.0.0 tags); the tag exists so the GitHub–Zenodo integration could publish the archived, citable version of the specification (DOI: 10.5281/zenodo.18833956).

[1.0] - 2026-02-28

Canonical public release (v1.0).

Date note: 2026-02-28 is the repository/specification release date. The archived citable version (DOI 10.5281/zenodo.18833956) was published on Zenodo on 2026-03-02, which is the date recorded in CITATION.cff and codemeta.json. Both dates are correct; they refer to different events.

Added

Established canonical specification under spec/v1.0/.
Introduced canonical JSON Schema endpoint: https://agent-manifest-spec.org/spec/v1.0/schema.json
Aligned manifest_version to “1.0”.
Standardized domain-based $id for schema.
Prepared release for DOI publication.

Changed

Updated all documentation references to point to v1.0 canonical endpoints.
Clarified versioning model separating specification version from historical development iterations.

Notes

This release supersedes all pre-1.0 development iterations.
Version 1.0 is the frozen canonical specification state.

[0.2.0] - 2026-02-14

Foundational consolidation. No modifications to the normative specification or JSON Schema.

Added

Pre-Execution Authority as explicit grounding doctrine (foundations/pre-execution-authority/).
DESIGN_RATIONALE.md (architectural reasoning).
ROADMAP.md (architecture-first direction).
CORE_PRINCIPLES.md, CONTRIBUTING.md, SECURITY.md.
Doctrinal references integrated into README.md.

Changed

Clarified the separation between doctrine and technical specification, and the stability-over-velocity posture.

Notes

The [0.1.0] section below was written on 2026-02-16 and documents the cumulative pre-1.0 baseline; several of its doctrinal items landed between the v0.1.0 (2026-02-04) and v0.2.0 (2026-02-14) tags and are the substance of this release.

[0.1.0] - 2026-02-16

Pre-canonical structural baseline.

Added

Introduced foundational doctrine under foundations/pre-execution-authority/.
Formalized Pre-Execution Authority as grounding principle.
Introduced DESIGN_RATIONALE.md.
Introduced ROADMAP.md.
Integrated foundational references into README.md.
Added normative terminology reference (TERMINOLOGY.md).
Added required stopping_authority declaration.
Added required audit_surface declaration.
Added required forbidden_actions field.
Added optional capabilities declaration.
Added optional language declaration.

Changed

Updated JSON Schema (spec/manifest.schema.json) for structural alignment.
Introduced conditional validation for data_handling.retention.
Improved purpose.primary_code constraints.
Harmonized accountability terminology.

Notes

Pre-1.0 development release.
Superseded by canonical v1.0 specification.
