@Tom Ehrensperger
There are two blank lines introduced in the latest.csv. See the discussions in your thread
http://discourse.weather-watch.com
example of the blank lines at: WXSIM 2018 Released! - #26 by hrvistaweather - WxSim - Weather-Watch.com
These blank lines will break the scripts which use latest.csv as the scripts expects the field-names in the first row and the corresponding unit of measurement in the second row.
I advised my users who’s script failed, to either use the official 2018 release from your website (which is OK) or use lastret.txt when using this test-version or the previous test-version.
My scripts can process either file, but the users will loose functionality when they switch from latest.csv to lastret.txt as lastret.txt contains less fields to process.
In the past 6 years there are multiple different script-versions processing latest.csv, no way anyone can find or warn the users with all their different native languages. So when they update WXSIM the latest.csv should be usable by them also.
