Android M, now known as Android 6.0 Marshmallow, is now in the heat of update season, as Google's latest mobile OS begins OTA rollouts to non-Nexus devices across the world. Now it appears a leak from a meeting at Lenovo has spilled the company's Android Marshmallow update roadmap for many of its devices.

The new leaked Android M update roadmap from Lenovo, if accurate, will undoubtedly come as good news to anyone who has tracked the company's possible Android update schedules for its devices.

As we previously reported, a leaked early version of a possible OTA rollout schedule from Lenovo, purportedly caught online by GSMArena in early November, seemed to show the company's most popular handsets wouldn't be getting an Android Marshmallow update until late 2016.

That leak couldn't be confirmed, though, and it doesn't look as authentic as the new Lenovo leak, found on Weibo and reported by Android Authority, which posted the photo on its site.

Lenovo smartphone owners should hope this leak is the authentic Android M update roadmap, because it shows an update schedule that's much earlier than before.

Specifically, the Lenovo K3 Note, the Chinese Lenovo Vibe X3, and the Chinese Lenovo Vibe P1 are slated in the candid conference room picture for an Android M update in March 2016.

Meanwhile, the international Lenovo A7000 is slated for an April 2016 update to Android Marshmallow 6.0. Finally in June, the international Lenovo Vibe S1 will get Android M, followed by the international Vibe X3 and A7000+ handsets.

While some of those with international Lenovo devices will have to wait until the summer of next year before they receive an OTA rollout of Android 6.0 Marshmallow, if the conference room leak is correct, that still beats waiting until sometime in mid-to-late fall 2016 for any Lenovo device to get an upgrade to Android M, as the first leak purportedly showed.

Still, as Lenovo hasn't officially announced an Android M update schedule for its devices, take the latest leak with the usual grain of salt.
