• implement gojq.Compare for comparing values in custom internal functions
• implement gojq.TypeOf for obtaining type name of values in custom internal functions
• implement gojq.Preview for previewing values for error messages of custom internal functions
• fix query lexer to parse string literals as JSON to support surrogate pairs ("\ud83d\ude04")
• fix priority bug of declared and builtin functions (def empty: .; null | select(.))
• fix string indexing by index out of bounds to emit null ("abc" | .[3])
• fix array binding pattern not to match against strings ("abc" as [$a] ?// $a | $a)
• fix sub and gsub functions to emit results in the same order of jq
• fix fromjson to keep integer precision ("10000000000000000" | fromjson + 1)
• fix stream option to raise error against incomplete JSON input
• improve array updating index and string repetition to increase limitations
• improve mktime to support nanoseconds, just like gmtime and now
• improve query lexer to report unterminated string literals
• improve performance of string indexing and slicing by reducing allocations
• improve performance of object and array indexing, slicing, and iteration, by validating path values by comparing data addresses. This change improves jq compatibility of path value validation ({} | {}.x = 0, [0] | [.[]][] = 1). Also optimize constant indexing and slicing by specialized instruction
• improve performance of add (on array of strings), flatten, min, max, sort, unique, join, to_entries, from_entries, indices, index, rindex, startswith, endswith, ltrimstr, rtrimstr, explode, capture, sub, and gsub functions
