Major Description
Bytes.toBigDecimal and Bytes.toBytes were removed in 0.90.x. Please add it back. We have data encoded using these methods. I don't think BigDecimal class as getBytes/toBytes methods. And even if it had it, if the logic of encoding it into bytes is different, it wouldn't work with the existing data. I am sure that lot of people might face this issue.
I will submit the patch in a day or two.
