The Android 5.1.1 update was expected to be released very soon for the Nexus devices.
Build numbersLMY47SandLMY47Wwere seen powering the Nexus 9 and the Nexus 7 (2013), respectively.
This update would likely be an incremental update for usual bug fixing.
Google is expected to release the next update quite soon to fix these issues.
Unlikely, but you never know.
Android 5.1.1 will be fixing all issues such as the memory leak issue along with other little bugs too.
But that… is merely speculation.
