 - Metadata resolvement will now give absolute and relative processed count updates via the log in case a lookup session takes longer than one minute. This is so large libraries do not give the impression of the tool having a hang-up. Example: `Current meta data resolvement status: [27399/46386] (59,07 %) - Next update in 1 minute.`
 - More memory performant query building for native SQL binary usage via lazy loading iterator.
 - Fixed bug where a malformed SQL query causes the tool to halt indefinitely. The tool will now exit and output the malformed queries for further diagnoses.
+- Quick saves for metadata json files so progress will be saved after a crash/premature exit by user.
 
 ## 1.6.3b
 - fixed "database not found" bug that some docker users experienced and could only solve it via a `OVERRIDE_DATABASE_LOCATION` entry
