 ## [Unreleased]
 
 ### Added
+- The file name of FlowDB's automatically generated at init config file can now be specified by setting the `AUTO_CONFIG_FILE_NAME` environment variable. By default this is `postgresql.configurator.conf`.
 
 ### Changed
 - FlowDB now enables partitionwise aggregation planning by default
+- The location inside the container of FlowDB's automatically generated config file has changed to `/flowdb_autoconf/$AUTO_CONFIG_FILE_NAME`.
 
 ### Fixed
 - Queries that have multiple of the same subquery with different parameters no longer cause duplicate scopes in tokens. [#6580](https://github.com/Flowminder/FlowKit/issues/6580)
