EngineX OS 5.0.4.2 (v5.0.4.2)

EngineX OS 5.0.4.2 (v5.0.4.2)

Full multi-model firmware release for Engine OS 5.0.4 standalone players and consoles.

What's new in 5.0.4.2 / 本版更新

• Source screen streaming visibility fix: turning off TIDAL (or any custom streaming service) in Settings → Services → Streaming now hides it cleanly from the Source screen instead of leaving disabled tiles or duplicate TIDAL icons under Connect New Sources. / 修复「设置 → 流媒体服务」中关闭 TIDAL（或其他流媒体服务）后，「来源」界面下方「连接新来源」仍残留已关闭服务或出现两个 TIDAL 图标的问题。
• Waveform style tile in the Control Center (#45): a CDJ-3000 style WAVEFORM COLOR control (DENON / RGB / 3BAND with colour swatches) switches the deck waveform in one tap. 3-Band uses the CDJ-3000 blue / gold / white palette. / 控制中心新增仿 CDJ-3000「WAVEFORM COLOR」的波形样式切换（DENON / RGB / 3BAND 带色带），一点即切；3-Band 改用 CDJ-3000 的蓝 / 金 / 白配色。
• Security hardening (#46): public images ship no SSH key and SSH stays off until you add your own; the key carried by earlier public images is removed from your deck on update; the deck's internal controls answer only the deck itself, so nobody on a shared Wi-Fi can restart, update or reconfigure it. See the README's security section. / 安全加固：公开固件不内置任何 SSH 公钥，自己没放公钥时 SSH 不开放；升级时自动清除旧版公开固件带的公钥；碟机内部控制接口只接受本机调用，同一 Wi-Fi 下的人无法远程重启、升级或改设置。详见 README「安全说明」。
• Factory Reset no longer hangs on "Shutting down..." when the erase cannot run (for example on battery power); the deck returns to its screen instead. / 「恢复原厂设定」在无法擦除时（如电池供电）不再卡在 Shutting down，会回到正常界面。
