MULTIPLE MERGES
komikku-app / komikku ★ 4.1k+

Two merged pull requests shipped in the official v1.13.3 release — added a "refresh selected entries" action to the library screen, and fixed the library-update strategy so manga without chapters still get refreshed correctly when restricted by their source.
