Borsh 2.0? Not planned

[frol]

So far we don't want to release any more breaking changes, but let's keep track of potential breaking changes here.

• Read/Write mutable reference in serialize and deserialize_reader is unnecessary #270
• Extract alloc feature (2.0 candidate) #281
• Adding Async support #139
• Cannot derive BorshDeserialize for a struct containing Box<[T]> #323

Please consider adding a VarInt type used for storing the lengths of things such as Vec.

@narodnik Please, create a separate issue with more details on the use-case. Vectors are already supported, so it is unclear what is the problem you face.
