Changelog

0.11.0 (2026-06-22)

Import: The database options from the library menu have been removed. There is no longer a need to manually flush data. To manually trigger a full import scan, there is a new button in the settings menu under the import category.
Library: Unsupported files are no longer fingerprinted and indexed into the sqlite DB. This is configured via the allowed_kinds setting.

Import: stop renaming legacy library data files (#538) (b4b106f)

ota: increase artifacts per_page to 50 to avoid pagination truncation (#560) (a5c78cf)
Settings Editor: Reset dictionary display on download failure (#532) (9415fe5)

Library: due to book cover extraction is part of the indexing process now, you should no longer see app stuttering when navigating the library view. (86a0a36)
Library: emit import progress in 5% steps (#561) (3184937)

dictionary: Fuzzy dictionary search no longer corrects first-character typos Fuzzy word lookup now uses a 3-character prefix pre-filter for performance. Searches where the query and the target word differ in the first three characters will no longer return results. For example, searching "bas" will not suggest "bar".
library: hashes are now calculated using BLAKE3 instead of the custom implementation using mtime which caused inconsistent hashing. BLAKE3 is more CPU and battery intensive, and slower.

WiFi: going from Nickel to Cadmus does not interrupt WiFi connection (6bfd7b4)
WiFi: previous DHCP leases will now be re-used, resulting in stable IP addresses. (6bfd7b4)

Library sorting is now precomputed instead of calculated on demand. Should benefit big libraries. (93cb8a1)
Memory usage should reduce a tiny bit, as the whole library is no longer loaded in memory. Memory pressure reduction depends on how big the library is to begin with. This will benefit folks with huge libraries. (93cb8a1)
optimize dictionary loading (#364) (5b23c62)
startup: Library import is now async, this means that it no longer blocks startup. (7fbf304)
Startup: Wifi management on startup is now async, instead of sync. This should improve startup speeds. (6bfd7b4)

Library: With the introduction of SQLite for managing library data, there is no longer a need to set library mode to filesystem or (fake) database. It is all now stored into SQLite. This means this field is obsolete and has been removed.
