Detailed Changes

1. React 19 Upgrade

• All relevant packages (subapp-react, subapp-redux, xarc-opt-react, xarc-react-router) now require react@^19.1.0 and react-dom@^19.1.0 as peer dependencies.
• DevDependencies and direct dependencies have also been updated to use React 19.

2. Redux and React Router Updates

• subapp-redux:
  • Now requires redux@^5.0.0 and @reduxjs/toolkit@>=2 (both as peer and dev dependencies).
  • react-redux updated to ^8.0.1 (peer and dev).
• subapp-react and xarc-react-router:
  • Now require react-router@^7.1.5 or ^7.2.0 as peer and/or direct dependencies.

3. Dependency Alignment and Modernization

• All packages have updated their dependencies and peerDependencies to align with the latest versions of React, Redux, React Router, and related libraries.
• DevDependencies for Babel, testing, and build tools have been updated to recent versions for better compatibility and performance.
• The lockfile (pnpm-lock.yaml) has been updated to reflect all dependency changes.

4. Package Version Bumps

• subapp-react bumped to 2.0.0
• subapp-redux bumped to 3.0.1
• xarc-opt-react bumped to 3.0.1
• xarc-react-router bumped to 2.0.0

5. No Major API Changes

• No breaking API changes were introduced in the code itself; the changes are focused on dependency updates and version alignment.

Impacts

• Projects using these packages must now use React 19+ and compatible versions of Redux, React Router, and related libraries.
• You may need to update your application code if it was using older versions of these libraries.
• The upgrade ensures access to the latest features, performance improvements, and security patches from the React ecosystem.
• The codebase is now aligned with the latest React and Redux releases, reducing technical debt and making future upgrades easier.
