Changes in this release Solved 3 issues that were reported, together with other improvements: Issue #1: EpXL can now store huge matrices (Matrix:TwoDimension object) containing more elements than the maximum number of columns in Excel (16384). Instead of storing each matrix element in separate spreadsheet cell, each spreadsheet cell now stores a whole matrix row as a string of semicolon-separated values in row-major order. Thus a 1010 matrix is stored in 10 spreadsheet cells, and EpXL can hypothetically store matrices up to a maximum of 16384 rows 16384 columns (assuming single digit elements, as a spreadsheet cell can store string of maximum 32768 characters). Issue #2: More robust epJSON export for objects with extended groups. Issue with slow epJSON export: Is now much faster, and memory overhead is reduced. Smarter algorithm that automatically corrects for incorrect choices, such as 'Autosize' vs 'Autocalculate' More robust import of dates: Date strings are now stored unchanged as a string in the input spreadsheet, not converted to Excel dates. Minor improvements to epJSON schema import.
