React on Rails 16.3.0 Release Notes

Upgrading from 16.2.x to 16.3.0​

Update your gem and npm package versions:

# Gemfile
gem "react_on_rails", "16.3.0"
// package.json
{
  "dependencies": {
    "react-on-rails": "16.3.0"
  }
}

Pro users: Use react-on-rails-pro instead of react-on-rails in package.json, and react_on_rails_pro instead of react_on_rails in your Gemfile. See the Pro upgrade guide for details.

Then run bundle install and your package manager's install command.

Key Changes​

Simplified Shakapacker Version Handling​

Removed obsolete minimum version checks (6.5.1) and example generation pinning (8.2.0). The gemspec dependency shakapacker >= 6.0 is now the only minimum version requirement, with autobundling requiring >= 7.0.0. PR 2247.

Bug Fixes​

  • Rspack configuration not applying to all environments: Fixed bin/switch-bundler crashing with Psych::AliasesNotEnabled on YAML files with anchors/aliases, and fixed the --rspack generator flag only updating the default section. PR 2275.
  • Precompile hook not configured when Shakapacker is pre-installed: Fixed the install generator not configuring the precompile_hook when Shakapacker was already installed. PR 2280.
  • bin/dev failing with --route flag: Fixed bin/dev command failing with "Unknown argument" when the generator was run with a --route option. PR 2273.

Pro Changes​

  • License-Optional Attribution Model: React on Rails Pro now works without a license for evaluation, development, testing, and CI/CD. A paid license is only required for production deployments. PR 2324.
  • Multiple License Plan Types: License validation now supports plan types beyond "paid": startup, nonprofit, education, oss, and partner. PR 2334.
  • Node Renderer Master/Worker Exports: Added public master and worker exports to react-on-rails-pro-node-renderer. PR 2326.
