 ### Bugfixes
 * Fixed issue where updated dependencies of substitution files did not retrigger a .db expansion.
+* db expansion happens at build time, not at install time.
 
 ### Other changes
 * Remove `IOCNAME:exit` PV. Stop loading `softIocExit.db` and now it's require that exposes the `BaseVersion` PV.
