3.1.11

• Using variable-length ints for more efficient representations of many types and values, where fixed-length ints had been used. In most use cases, this should result in shorter binary representations.
• Added FlexUnsignedIntType that can serialize any non-negative JavaScript integer. Generally more efficient than fixed-length ints for distributions skewed towards smaller values.
• Limits removed from array lengths, map sizes, set sizes, and octets lengths
