Increased Timeout for Client-Side Caching
When a component is generated on the server from metadata, the
page loads from a client-side cache of the indexed database. The client-side cache
timeout has increased from 15 minutes to 8 hours, with a refresh interval of 15 minutes.
This increased timeout can result in faster page loads for users who bootstrap the
application frequently or click links from outside the application to open a new browser
window or tab to Lightning Experience.
