Migration Guide

Upgrading from v0.9.14 to v0.9.17

1. Update package imports (v0.9.15+)
// Before (v0.9.14)
import { generateKeyPair, signReceipt, verifyReceipt } from '@peac/core'

// After (v0.9.15+) - use specialized packages
import { generateKeyPair } from '@peac/crypto'
import { signReceipt, verifyReceipt } from '@peac/protocol'

// Or use the SDK wrapper for backwards compatibility
import { generateKeyPair, signReceipt, verifyReceipt } from '@peac/sdk-js'
2. Update issue() return handling (v0.9.17)
// Before
const jws: string = await issue(payload)

// After
const result = await issue(payload)
const { jws, subject_snapshot } = result

Release Process

PEAC follows semantic versioning with release trains focused on stability:

  • Pre-1.0 releases use the 0.9.x series
  • Wire format peac.receipt/0.9 is frozen across v0.9.x
  • Library APIs can change pre-1.0 (pin versions in production)
  • Breaking changes are documented in release notes with migration paths
