The following release notes list only changes since [3.10-beta1](/sdk/changelogs/3.10-beta1/). ### Changes to Firmware * ``health_service_get_measurement_system_for_display`` no longer crashes when called on real watches. * ``rand`` is now seeded from the hardware RNG on app start, as it was in firmware 3.4 and earlier. * An issue causing the sleep graph to sometimes be blank on the deep sleep display of the Health app was resolved. ### Changes to SDK * `CFLAGS` and `LINKFLAGS` env variables are now correctly honored by the app build process. * JSON files under the `src/js/` directory are available to `require` in newly-created projects. * ``persist_write_bool`` and ``persist_write_int`` are now correctly documented to return the number of bytes written on success.
