Changes in this version:

- A number of new pivot table function have been added:
- geometric and harmonic means,
- variances and standard deviations,
- counting specific numbers,
- counting strings based on regular expressions,
- kurtosis,
- skewness,
- most frequently occurring numbers and strings.

To maximize performance, (most of) the pivot functions can make use

of up to 64 processor cores.

- Added optional chi-square tests for generated pivot tables.

(Hints: tables must specify the “Grand total” column and row; if there are not any column fields, the expected test chi2 values are assumed to be uniformly distributed.) - Sort ranges and keys can be saved and re-used easily.
- In the IF() functions now only one of the two conditional parameters is evaluated. Previously both were calculated so in this update IF() functions will be proportionally faster.
- The chitest() function now returns P(X > c^2) instead of the P(X < c^2). The “Settings > Legacy Compatibility” option enables preserving the previous behavior.

**March 30, 2018 - 16.8.3 Update**

- Data copied to the Clipboard is now available after closing a given workbook and/or GS-Calc.

**November 23, 2018 - 16.8.4 Update**

- The “Replace/All” commands couldn’t be used to replace empty cells. In this update the “Find/Find All/Replace/Replace All” commands can be used find and replace empty cells and to delete cells containing specific values.
