There's no change since what we wrote on the releases page. Most of the supported devices are on the 2023-09-05 patch level. As explained on the site, AOSP had the patch level string set to 2023-09-01 for all devices and we didn't delay the release to make an aesthetic change for the devices with all the 2023-09-05 patches.
Our current stable release for the Pixel 6, Pixel 6 Pro, Pixel 6a, Pixel 7, Pixel 7 Pro, Pixel Tablet and Pixel Fold has the 2023-09-05 patch level already and there will be an early update to the 2023-10-01 patch level today.
Pixel 4a is end-of-life and is receiving extended support. The patch level is permanently frozen going forward since it won't ever get the required firmware patches.
5th generation Pixels are on 2023-09-01 because there hasn't been a 2023-09-05 release of the Android Open Source Project or stock Pixel OS with Qualcomm firmware/driver updates.
Pixel 7a is the only device with standalone Qualcomm Wi-Fi and is in the same situation as 5th generation Pixels.
