This release is focused on performance enhancements.
Changes
- Hibernate lazy loading was not working because of Kotlin closed by default classes
- add Hibernate caches: second level, collections, query
- enhance code path to reduce number of database queries
- fix a bug where Series thumbnail would be retrieved by the first book in the collection, instead of the first by number
- remove (unused) bi-directional OneToOne relationship between Book and BookMetadata to reduce database fetch
