I seen a post on twitter the other day that said it had but i haven't seen anyone talk about it on here yet and the post has been changed in discussion yet.
I dont think it was already released and there was no official announcement of the release yet. If it is already release then topics of the relased of 0.14 will flood the topics on this forum. But as you can see there was no flood yet and this is just a sign that possibly that the new bitcoin core was not yet released. But let us not worry it will be released sooner since it was announced that they will release it this year.
