This feature was announced today in the “Post-V8” thread. (KiCad has a Post-Vx thread for each KiCad version for some years now).
That is unlikely to happen. Increments in the third number are bug fix updates and do not introduce new features. KiCad is on a yearly mayor release schedule, and apparently they want to have the new version out just before FOSDEM, so that would be in February. With all the new features, also new bugs tend to be introduced, and plugins often need changes to work with the new KiCad version. For these reasons, many people wait a few months before updating to the next stable version.
