Rails 8 container images come pre-configured with all necessary components, reducing setup complexity and configuration needs

Emphasis on making Rails accessible for single-person development teams while maintaining scalability for larger applications

Moving away from cloud vendor lock-in and high-margin services toward simpler, self-hosted solutions using basic Linux servers

Prop Shaft replaces older asset pipeline solutions with a simpler, modern approach aligned with HTTP/2 capabilities

Strong focus on backwards compatibility while modernizing the framework and removing outdated patterns
