## [0.8.1] - 2024-04-30

### Added

- MTSU_SECURE option to allow enabling and disabling forced SSL

### Changed

- Unified response props to start with capital letter

## [0.8.0] - 2024-03-23

### Added

- Crop gallery covers to fit the aspect ratio of the thumbnail (2:3) better. Also, when it comes to multipage images, Mangatsu tries to find the cover.
- Returning the total count (TotalCount) of galleries when fetching (helps with pagination)
- meta_title_hash column to save the hash of the gallery title. Helps to save time and resources when parsing titles for metadata
- MTSU_FUZZY_SEARCH_SIMILARITY environmental variable to set the similarity threshold for fuzzy search. Default is 0.7 (70%)
- MTSU_LTR environmental variable. For now used for the default to crop gallery covers when needed. Otherwise, the language of the gallery title is used to determine it
- fuzzy (true|false) query parameter to enable or disable fuzzy search when starting metadata task

### Fixed

- Shuffling not working when fetching grouped galleries
- Paging when shuffling enabled (was returning the same first page)
- Various issues with updating galleries
- Crash when trying to count images of an archive that could not be opened
- A rare error when DB UPDATE was rollbacked
- DB lock when creating thumbnails with semaphore

### Changed

- Improve performance when fetching galleries by constructing SQL filters only once
- Return OrderedMap ({ []uuid, []{uuid: gallery} }) instead of a normal mapped results ([]{uuid: gallery}) for grouped galleries
- Store page thumbnails in thumbnails/[gallery uuid]/p/ directory instead of thumbnails/[gallery uuid]/. Cover is stored as thumbnails/[gallery uuid]/cover.[ext]
- Refactored the way galleries are fetched, updated and deleted
- Better gallery validation when updating
- Improve metadata parsing logic and performance
- Improve gallery update and fetch logic
