 ### ⚠ BREAKING CHANGES
 
 * generalized wildcard queries ([#458](https://github.com/GenSpectrum/LAPIS-SILO/issues/458))
+  * The preprocessing config field pangoLineageDefinitionFilename has been renamed to lineageDefinitionFilename.
+  * We now accept a YAML lineage definition file instead of a Pango alias key. A script (scripts/alias2lineageDefinitions.py) is provided to transform a list of lineages and an alias into the required file format.
+  * Input and query validation now checks whether the provided lineage exists in the defined lineages, and errors are thrown if validation fails.
+  * The metadata type pango_lineage has been removed
