1.1.0

[shuding]

Highlights for This Release

1. Built-in & stable serialization for SWR keys

useSWR({ query: graphql`...`, variables }, fetcher)
useSWR({ query: graphql`...`, variables }, fetcher)
useSWR({ variables, query: graphql`...` }, fetcher)
// ^all recognized as the same resource

For array keys too, it's safe to do the following:

useSWR([ `...`, { variables } ], fetcher)

2. revalidateFirstPage for useSWRInfinite

This is a new added option for useSWRInfinite (defaults to true), you can use it to control if the first page should be revalidated when changing the size or doing a mutation.

3. Better TypeScript support

• Key / arguments
• Conditional / dependent
• Constant keys
• Returned data
