+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
--- End diff --
No, I mean that the new RLEv3 needs to support both 64 bit and 128 bit
integers. The specification of course could just define the spec using 128
bits, but the Java and C++ implementation would likely be split.
