Previously columns with negative int64 values were stored either as float64 or string depending on whether the negative int64 values are bigger or smaller than -2^53. If the integer values are smaller than -2^53, then they are stored as string, since float64 cannot hold such values without precision loss. Now such values are stored as int64. This should improve compression ratio and query performance over columns with negative int64 values.
