Dear Gretl User-List,

I'm excited to announce the release of version 0.7 of the fdensity package for Gretl. This package allows you to compute and visualize conditional densities of a variable x for each value of a discrete variable d, also known as the "factor."

The key changes in this new version are:

1. Support for list of series in x:
- If multiple series are passed to x, a grid of kernel density estimation (KDE) plots will be created. - This is currently only supported for the scripting mode. In GUI mode, only a single series x can be selected.

2. New cumulative parameter:
- You can now compute the cumulative distribution function (CDF) instead of the probability density function (PDF) by setting cumulative=TRUE.

3. New grid parameter:
- You can now control whether a grid is displayed on the plots by setting grid=FALSE.

4. New logscale parameter:
- The y-axis can now be displayed on a logarithmic scale (base 10) by setting logscale=TRUE.

5. GUI control parameters:
- The logscale and cumulative parameters are now exposed in the Gretl GUI.

6. Increased minimum version requirement:
- The minimum required Gretl version has been increased from 2021a to 2023c.
