It seems it was pushed to 18/11. Here follows the notice posted on Discord:
> Hey @everyone, apologies for the Blender 5.0 false alarm earlier today. The announcement was scheduled to go out this morning, and I even double-checked the official release date last night before bed to confirm everything was still on track. Unfortunately, an unexpected delay pushed the launch back at the last minute. Blender 5.0 will now officially release on November 18. Thank you all for the enthusiasm and understanding, your support means a lot, and the wait is almost over.
