    +title: Evolving Draft for ORC Specification v2
    +---
    +
    +This specification is rapidly evolving and should only be used for
    +developers on the project.
    +
    +# TO DO items
    +
    +The list of things that we plan to change:
    +
    +* Create a decimal representation with fixed scale using rle.
    +* Create a better float/double encoding that splits mantissa and
    +  exponent.
    +* Create a dictionary encoding for float, double, and decimal.
    +* Create RLEv3:
    +   * 64 and 128 bit variants

    I think you meant base 128 and 256 varints.
