Compatibility and validation:
- Published as Lagrange-1.5.1.apk (63,691,461 bytes); SHA-256 1b1306961be9c95f8d076293c7c803d9b9980424e1d0b1b7d0ffea7ba79f3766 verified. Release workflow run 33733443965 passed. Local verification passed 632 JVM tests with 0 failures, 0 errors, and 0 skipped, Kotlin and Android-test compilation, lint, and debug/Android-test APK assembly; local signed release assembly was unavailable because signing credentials are CI-configured. Device/emulator checks remain outstanding for volume-button navigation, download notifications, PDF hyperlink interactions, and browser Back behavior.
Known limitations and deferred work:
- BOOX/Android e-ink physical validation remains deferred; the minimum SDK is unchanged.
- Native AppAuth/Custom Tabs OIDC remains deferred until BookOrbit provides deployed mobile-redirect support and the identity-provider callback is registered.
- MOBI, AZW, AZW3, and FB2 remain unsupported.
- Broader offline RAR/7z extraction and additional product work remain deferred.
Upgrade notes:
- No migration action is currently identified for the 1.5.1 changes.
