# Release Notes

URL: https://docs.nexart.io/docs/release-notes

What changed at the current documented baseline across @nexart/ai-execution, @nexart/agent-kit, @nexart/cli, @nexart/policy, and NexArt Node.

## Overview

This page summarizes the current documented baseline. For exact version numbers and how they relate to each other, see Versions.

## @nexart/ai-execution 1.4.0

This release is additive. It introduces the V2 record schema (`ai.execution.v2` snapshot type, `cer.ai.execution.v2` bundle type, protocolVersion `1.3.1`, `jcs-v1` canonicalisation). V1 (`ai.execution.v1` / `cer.ai.execution.v1`) is unchanged and remains fully supported.

- New V2 API surface: `createSnapshotV2`, `sealCerV2`, `certifyDecisionV2`, `verifyCerV2`, `verifyCerV2Async`, `verifyAiCerBundleDetailedV2`, `certifyDecisionFromProviderCallV2`.
- New V2 evidence and protected-set helpers: `buildModelEvidenceV2`, `evidenceString`, `deriveProtectedSetV2`, `validateSnapshotV2Schema`, `decisionRefDomain`.
- New AIEF exports: `verifyAief`, `mapToAiefReason`. See AIEF.
- New confidential V2 helpers: `sealConfidentialV2`, `verifyConfidentialV2` and their async variants, `computeCommitment`, `generateSalt`.

## @nexart/agent-kit 0.6.0

Adds `certifyAiExecutionV2(params)`, returning `{ bundle, certificateHash, executionId, openings? }`. Existing V1 surfaces (`wrapTool`, `certifyDecision`, `certifyDecisionWithPolicy`, `createProjectSession`, `exportProjectBundle`, `importProjectBundle`, `verifyProjectBundleDetailed`, `startWorkflow`) are unchanged. They stay V1 forever: `wrapTool` and `startWorkflow` step bookkeeping have no V2 counterpart.

## @nexart/cli 1.3.0

The CLI verifies both `cer.ai.execution.v1` and `cer.ai.execution.v2` bundles (dual-schema verification). It adds an `--aief` flag on `nexart ai verify`, projecting the AIEF v0.2.5 Section 9 result (exit 0 = PASS, exit 1 = FAIL). See AIEF for details.

## @nexart/policy 0.1.0 (new package)

A new, standalone producer-side package for declarative, data-only policy predicates over captured execution fields. See Policy SDK.

## NexArt Node 0.25.0

`/api/attest` now dispatches by bundle schema, accepting both `cer.ai.execution.v1` and `cer.ai.execution.v2`. Unknown AI-family schemas (for example `cer.ai.execution.v999`) fail closed rather than being accepted or best-effort processed.

## What Did Not Change

Unchanged in this baseline
- The canonicalisation protocol itself and the set of supported protocolVersion values.
- `projectHash` semantics for Project Bundles.
- `certificateHash` coverage rules for existing V1 records.
- CLI exit codes for existing commands.
- Verification of existing V1 records.

## Next

- Versions: the four independent version axes and current baseline.
- AIEF: verifying V1 and V2 bundles.
- Policy SDK: the new package.
