But this explicitly confirms that SEGA is done using the DRM. Though it currently doesn't look like they're planning to patch it out of any other games. It at least looks like they're done adding it to any future releases.
The notes don't mention the removal of Denuvo, but the .EXE file is much smaller (20mb vs 220mb, i think.) than it was previously, which usually means it's been taken out.• Fixed an issue related to shaders and shadow rendering affecting lighting/skin tone (most noticeable during cut scene at the end of chapter 6)

• Added border artwork displayed during areas with locked aspect ratio when played in non-16:9 display modes
• Added Background audio slider in audio menu
• Added UI toggle in settings menu
• Added target monitor output selection option for multi monitor setups in advanced graphics menu
• Added support for QWERTZ and AZERTY keyboard layouts
• Fixed an issue where disconnecting a controller during conversation could cause a soft lock
• Fixed an issue where mouse cursor would be confined within application window while in menus
• Fixed an issue which could cause a crash when playing the fishing mini game
• Fixed an issue where the game could crash if the installation folder path includes a dot
