As we all know Alcatel announced the Marshmallow update coming either March or April and it's the last week of April next week. So it could probably two things:
A. The Marshmallow update could come out next week
B. The Marshmallow update could be delayed
I dunno bout the bug fixing status but what I can say is, at least they are taking their time fixing and preparing the update for us, but I think there is a possibilty the update could be delayed...
