Full Changelog: https://github.com/rails/importmap-rails/compare/v0.8.2...v0.9.0

• NEW: Added --download or -d to bin/importmap to download pinned packages from the CDN into vendor/javascript. This removes a runtime dependency on the CDN. Note that you must add //= link_tree ../../../vendor/javascript .js to your app/assets/config/manifest.js file when using Sprockets (this is automatically done on new installations).
• UPDATE: Upgraded to ES Module Shims 1.2.0
• CHANGE: Pins are no longer preloaded by default. You most explicitly add preload: true to have them be preloaded.
• CHANGE: Demand a minimum Ruby version of 2.7, in line with Rails 7.
• CHANGE: Use a minimized version of ES Module Shims by default.
