Can newly released apps by Google for chromecasts be used and also updated in the Chromecast?
Can a Chromecast be unrooted? If not will it likely be possible in the future?
Chromecast actually "pulls" the app from the vendor's site, with the possible exception of Netflix, so it's always running the newest version.
New apps on the Google whitelist are immediately available on Team-Eureka whitelist.
You can also switch it to use the standard Google whitelist if you want.
However, if a new application requires a specific firmware build, as was the case when Cast SDK 2.0 rolled out, then it
may not work, because the custom builds lag behind the Google OTA roll-out. Team-Eureka has lives outside of XDA, as we all should.
Because of this Team-Eureka has been releasing Stock no updates ROMs soonafter a Google OTA is released. These stock ROMs
do not include any Team Eureka features and behave exactly like non-rooted Chromecast, except they preserve root (you can still use FlashCast to flash ROMs/mods) and they
do not auto-update, because update would mean losing root.
As for un-rooting. It's possible to flash a plain stock ROM if you
really want to. That would mean permanently* losing root on the next automatic update.
If you are already rooted and don't want root, I would much rather trade you for a non-rootable Chromecast and preserve your rooted one.
It's
not like a phone where you can unroot then get root back later.
* At least until another exploit is found, though that seems less and less likely as time goes by.
