What is the maximum array size for a .DDT in Control Expert (formerly named Unity Pro)?

Previous to CE v15.1 the array size of the DDT could not exceed 64K bytes.
As of CE v15.1 the DDT maximum array size was increased to 2M bytes.

Note: the max 'Array Variable' size remains at 64K for all versions and is not expected to change.

***The release notes of v15.1 implied that the array variable size increased but it did not. ***
