trpc/trpc v8.3.0

on GitHub

• Batching fix: ability to pass undefined to batch inputs without them being type-casted as null - #669
• HTTP requests: flatten POST HTTP requests, skip wrapping in input property - #671

Both of the above changes shape of HTTP-requests, but backwards-compatability and tests are added, in case someone uses tRPC as a public API.

Thanks to @simonedelmann for the idea on #669!
