3435022 - Composable Storefront versioning alignment with Commerce Cloud

1. Version alignment between Commerce Cloud and Composable Storefront

2. Composable storefront uses the Angular framework, which publishes new major versions twice a year. These major versions of Angular have 18-month long-term support windows. In the past, composable storefront was updated twice a year with the new Angular framework. This is changing, as follows:

• The Angular framework update for composable storefront will take place once a year, in February, starting with the release in February 2024.
• Updates to the Angular framework require updates to customer storefronts because framework updates include breaking changes.
• Composable storefront may also include backwards-incompatible changes to the storefront architecture, only when necessary.
• Feature updates after the February update will normally be backwards compatible, using feature flags or by triggering them through the presence of page components.

3. The following is a summary of the new release cadence

• February: Angular framework update, with changes to your storefront usually required, due to unavoidable breaking changes introduced in this release.
• March to November: New release every month, usually with new features, usually backwards compatible.
• December to January: Bug fix releases only because the next framework update is being worked on.

The February 2024 update release uses Angular 17. The following planned framework update will be in February 2025, likely with Angular 19. Final plans will be confirmed near the release date
