Hi all, As part of V7.0 release we are planning to remove a number of functions that have either been deprecated or are internal functions no longer used. Please could you review this list and let me know if you believe any of these are still needed?

Thanks Tim

- ds.listOpals
- ds.setDefaultOpals

- ds.table1D
- ds.table2D
- ds.vectorCalc
- ds.look
- ds.message
- ds.ranksSecure
- ds.testObjExists
- ds.dataFrameFill

Internal client helpers deleted:

- meanByClassHelper0a, 0b, 1, 2, 3, 4
- subsetHelper
