This page lists bug fixes and changes in beta build 4.5.0.21 that have occurred since 4.5.0.16.

Clipboard

A few bugs involving mishandling of certain special characters.
Minor updates to when pasted text is quoted.
Fixed bug when time-of-day values are copy-pasted, in which some displayed as date-time values afterwards rather than just time-of-day.
Several bugs related to copy-paste to and from MulitTables.

Diagrams

Text typed into text node doesn't display initially.
When drawing arrows from variables to/from lists, some problems relating to identifiers within cell expressions not getting automatically commented and uncommented when they should.

Fixed a small and rare issue related to numeric round-off, in which for example (0.8*10)*x and (10*0.8)*x produced slightly different results with slightly different round-off error for certain real values of x.

Fixed inconsistencies relating to the comparison of complex numbers. You cannot say that 1j<2j -- complex numbers are incomparable. Made several adjustments to comparison operators and functions like Max to reflect this accurately and clearly.

When a date format (display numbers as dates) is active, changed it so that the components of complex numbers are not shown as dates. 30-Sep-2013 + 10-Aug-1992j would never make sense.

When using A[I=J] on index J longer than I, no warning is issued anymore in 4.5. When J was a local index, the warning was still showing.

Improved handling of cases when object collisions occur when adding or merging a module or library. In particular, when the collision involves distinctly different object types, it is clear without asking the user that these should be kept distinct -- never merged. So appropriate renaming occurs more seamlessly.

When path to Libraries directory was too long (for a non-default install location), linked libraries were not being found automatically and Add Library... was not opening to the correct directory.

The Assignment operator, (A:=B), which sets a table definition when used from a button script when B is an array, now preserves the table type. So if the table was a DetermTable, the assignment no longer changes it to a Table. Note: If your intention is to change it to a Table, then assign it to be Null first, then do the assignment.

Assignment and slice assignment not preserve controls in tables. If an edit table contains Checkbox or Choice cells, and you change the value of the cell from a button script to a value that appears in the Choice or to 0 or 1 for a Checkbox, the existing control is preserved in that cell, but is changed to select that value.

Several oddities and extra error message boxes when a domain contains an invalid expression. Small visual layout changes.

Exception when getting description (model-specific)
When you have a DefTable for a SubTable, CATable::SetDataByElements or CATable::SetDataByLabels followed by CATable::GetDataByElements or CATable::GetDataByLabels, with no call to CATable::Update, did not reflect the changed cell.
When you have a DefTable for a SubTable, CATable::Update now imports any changes made so the SubTable's parent cells by other paths while the CATable was being held.
Support for the new MultiTable table type was added to ADE's DefTable.
