Full Changelog: v2.0.1...v2.0.2

v2.0.1

In this patch release, we majorly improved typing support and SWR can infer the types based on the configuration.

• When the suspense option is true, the returned data will exclude undefined and the isLoading will always be false.
• When the fallbackData option is provided, the returned data will be the same type of fallbackData, and the isLoading will always be false.

Here's a demo for it:

swr-2.0.1.mp4

• types: make FullConfiguration generic by @huozhi in #2273
• type: enforce array literal as tuple by @promer94 in #2283
• Improve type test by @promer94 in #2289
• update bunchee to remove the extra target cli option by @huozhi in #2298
