## Errata 
- Data: 
	- Unfortunately, we found an error in the aggregated variables of the year of birth of the children in 
	  version 2-0-0. Instead of reporting the aggregated information for the 4 youngest children, 
	  the aggregated information for the 4 first-named children are reported. 
	  Specifically, the following variables are affected and will be updated in version 3-0-0:
		
		- k1gbjkind1agg2, k1gbjkind2agg2, k1gbjkind3agg2, k1gbjkind4agg2 
		- k1eigkind1agg, k1eigkind2agg, k1eigkind3agg, k1eigkind4agg 
		- k1hhkind1agg, k1hhkind2agg, k1hhkind3agg, k1hhkind4agg 

## [2.0.0]  2021-02-17
### Added
- Documents related to data package
    - Added variable-questionnaire (wave 1) (DE)
### Fixed
- Data:
    - Unfortunately, we found an error in version 1.0.0 during a check. 
      In the spell data set, the episode starts had not been formed correctly in relation to 
      the exam completions from the individual dataset. Therefore, the dates in the episodes were not 
      correct. We have now fixed this bug in version 2.0.0. If you did not work with the spell data set, 
      this error does not affect your analyses.
