# Version changes

This page contains details of the changes between versions. Only changes that could theoretically impact the behavior of existing apps in Live mode to a newer nedyx version are listed here.

## Changes in version 1.83

* PDFs are now using the same locale as the current browser.
* The = operator can no longer be used in conditions.
* The DOWNLOADEXCEL function was including unexpected cell formats.
* The maximum amount of cells which are returned by functions or operators has now a limit of 500,000. If more cells are returned, a !LIMIT error is displayed instead.
* The COUNT, RANGETOCSV and CSVTORANGE functions have now new default parameters (see function description). Exisiting functions have been automatically modified, so that they work as before.
* The SETSELECTION function has been renamed to SWITCH.
* The On switch action is now executed if a menu is switched by the SWITCH function. To prevent recursive calls, the ISUSERACTION function is recommended to use.
* If the GETDATA function is called with "forbidden words", like delete, drop, etc., the function is now executed.
* A cell reference to a cell containing 0 returns now 0 (before an empty value was returned).
* The widget assignment operator (=) returns now the assigned range (before it returned an empty value).
* The idle time check works more reliable now.
* In cell edit mode, all decimal places are not displayed.

## Changes in version 1.66

* Most functions return now an error if an error is used as parameter (Exceptions are e.g. COMBINE, and the IF function).
* Cell-based conditions in the IF function were returning true if the condition was an error. Now it returns an error as well.
* The function SETSELECTION (now SWITCH) was sometimes switching to a wrong position.
* DECTOHEX now returns letters in upper case.
* Tooltips are now displayed on empty cells as well.
* The functions SUM, MIN, MAX and COUNT returned sometimes unexpected values, especially in case of non-numeric or emtpy cell values.
* The tooltip property had an unexpected impact on the vertical alignment of table cells.
