Change log includes fixes for wingray and stingray - maybe VZW will push 4.1.2 as the OTA for 3G/4G Xoom?

Judging by that changelog, it appears a new LTE radio is on the way for Stingray...07.23.00. We know the leaked JRO03H build that hit back in August had a new CDMA radio included...03.1A.66PS, but the LTE radio remained the same. Sadly, since the radio firmware on the Xoom is flashed to the actual radio hardware rather than to a storage partition, it can't be dumped for flashing, and thus the only person that actually has that new CDMA radio is the guy who leaked the JRO03H Stingray build originally.
Maybe now that 4.1.2 has updated the LTE baseband, we'll FINALLY get an official Jelly Bean OTA for Stingray. It seems like Google and Motorola have done their part with providing an OS build and radios respectively...now Verizon just needs to approve it.
On a slightly depressing note for those who have ever built AOSP for Stingray...I had a very brief conversation on my G+ with JBQ tonight about the situation with binaries after noticing that every single device had updated Jelly Bean binaries...except Stingray. The latest Stingray binaries are for ICS build IMM76L.
He told me that Stingray binaries will no longer be provided for AOSP. Even though they were always marked as "archived, for reference only" (due to the fact that they don't have a license to redistribute the LTE/CDMA blobs), you could still download up-to-date AOSP binaries for Stingray that at least covered the basics like WiFi and graphics, even though it was on an unsupported basis.
JBQ said tonight "We stopped trying to support stingray when it became clear that we wouldn't be able to license the network stack." So I guess that means that securing a license for Stingray's CDMA/LTE blobs is a lost cause and as such, they've just stopped providing binaries altogether. Sad that they were able to secure redistribution licenses for the CDMA/LTE blobs on toro (VZW Galaxy Nexus), toroplus (Sprint Galaxy Nexus), and crespo4g (Sprint Nexus S), but not for stingray. *shrug*
This, of course, has no affect on actual OTAs. As long as Google keeps releasing OTAs for Wingray, Stingray will get them too albeit on a delay due to Verizon.
It's just sad that, for the longest time, you've been able to build AOSP for Stingray, just without a working radio. Now, if you build it, you'll have to pillage the latest OTA for drivers that cover even the most basic functionality like graphics. Ah well.
OK rant over.
