CrossLingua v1.1.0+crosspoint.1.5.0

CrossLingua 1.1.0

Based on CrossPoint Reader 1.5.0.

This release introduces CrossLingua as a bilingual-first e-reader firmware: translate books directly on the device or prepare them with Calibre, then choose how the original and translated text should appear.

🌐 On-device translation

• Translate only the current chapter or the entire book directly on the reader.
• Chapter translation typically takes 1–3 minutes.
• Full-book translation typically takes 10–30 minutes.
• Translation results are cached on the SD card for offline reading.
• The original EPUB remains unchanged.
• Added live progress reporting for chapter and full-book translation.
• Added retry and backoff handling for rate-limited translation providers.
• Added safer recovery from interrupted or incomplete translations.
• Improved memory management during network-heavy translation operations.

Translation time depends on Wi-Fi connectivity, translation-engine availability and the amount of text.

🤖 Translation engines

• Google v2
• Google v1 / HTML
• Google legacy compatibility mode
• Azure
• DeepL
• DeepL Pro
• OpenAI
• DeepSeek
• Gemini

API keys are configured separately for engines that require them.

📖 Lingua reading modes

Added eight ways to display bilingual content:

• Interlinear — compact translation annotations above their corresponding source lines.
• Side by Side — synchronized source and translation columns.
• Interleaved — alternating original and translated paragraphs.
• Tooltip — sentence translations displayed in a small overlay while reading.
• Page Translation — a larger translation overlay for the current page.
• Original Only — source text without visible translations.
• Translation Only — translated text as a clean monolingual book.
• Normal — original and translated paragraphs rendered in the EPUB’s regular flow.

Mode-specific settings include:

• Translation text size.
• Translation colour: Black, Grey or Light Grey.
• Front or side buttons for Tooltip and Page Translation controls.
• Tooltip looping or automatic continuation onto the next page.
• Independent translation-column colouring in Side by Side.
• Landscape and portrait bilingual layouts.

The display mode can be changed without translating the text again.

🔌 Calibre bilingual EPUB support

• Added support for translations embedded directly into EPUB files.
• CrossLingua recognizes language-tagged translated paragraphs.
• Bilingual EPUBs prepared with the Ebook Translator Calibre plugin can use the same Lingua reading modes without translating the book again on the device.

📚 Bookshelf

• Added an optional cover-based Bookshelf interface.
• Added a 3×3 book and folder grid.
• Added progressive EPUB cover generation in the background.
• Generated cover previews are cached on the SD card.
• Added series and folder navigation.
• Hidden and system folders are filtered according to file-browser settings.
• Improved cover-generation performance and reliability.

🔤 EdsLab font

• Added EdsLab, a custom reading font developed specifically for CrossLingua.
• EdsLab is built into the firmware and used as the default reading font.
• Custom .cpfont families can still be installed from the SD card.
• Improved font caching and prewarming for bilingual overlays.

📖 Reading improvements

• Added direct access to Text Settings from the reader menu.
• Preserved the reading position when chapter layout must be rebuilt.
• Improved position recovery after font, layout or Lingua-mode changes.
• Improved translated-text hyphenation and Ukrainian extended-Cyrillic handling.
• Improved footnote placement in Interlinear and Side by Side modes.
• Improved RTL handling in bilingual layouts.
• Improved sentence splitting for Unicode whitespace and paragraph boundaries.
• Improved overlay sizing, paragraph indentation and page refresh behaviour.

🌍 Interface and localization

• Added Lingua and Bookshelf interface strings across supported UI languages.
• Reorganized Lingua settings into mode-specific submenus.
• Added clearer translation progress, fallback and error dialogs.
• Renamed older experimental terminology to the final CrossLingua mode names.

📱 Device support

CrossLingua supports:

• Xteink X3
• Xteink X4

📦 Release infrastructure

• Added independent CrossLingua versioning alongside the upstream CrossPoint version.
