Version 1.5.4 brings a more complete EPUB translation and bilingual reading experience, along with new bookmark support for PDF and EPUB so you can return to important parts of long documents more easily. We also improved translation progress visibility, notifications, and task stability to make the translation workflow smoother. This update also adds support for local embedding models to strengthen on-device semantic retrieval and intelligent processing. At the same time, we improved search, import, and large-document performance, with better stability in low-memory situations.
