The format is based on Keep a Changelog.


## [1.0.1] - 2021-06-17
## Errata
- Data:
	- Unfortunately, we found errors in some variables: 
	For the variable dem11a_h (nationality), there was an error in aggregation for data from the 17th Social Survey (2003), 
	so that students with only German nationality were assigned to those with dual nationality (German and other).
	The variables abr02a to abr02d (type of stay abroad) were not aggregated correctly for the survey years 2003 and 2009, 
	so that students who had not answered this question were also grouped into the respective types of stay abroad.
	For the variable ped04 (time of vocational training), the missings were not set correctly for the survey year 2016. 
	The same applies to the variables abr08a_v21 to abr10i_v21 (sources of funding for study abroad).
