No, they did not release it for the G5+... To my knowledge, it hasn't even been pushed to a MFN group for testing yet.
In other words, don't expect it anytime soon. Once Moto tests it internally, they select a group of Moto Feedback Network users to test it, and that runs for 30-60 days before general release, assuming there are no issues discovered while testing. If there are issues in the beta/soak test, it returns to development, it's fixed, and the process starts over. Nougat for the Moto X Pure took almost 8 months.
