Problem with open-source projects of this scale is there is no real deadlines, management and other usual motivators for the team. Not saying this is bad or flawed model, it just different. As a consequence you have to live in environment where "plans", "roadmaps" and deadlines are flexible to such an extent they essentially cease to exist in usual understanding (there is no bonuses for being on schedule or punishment for missing deadline). They surely have plans and dates in mind, but those are as good as anybody's guess.

The paradigm of open source development are in motivation everyone capable to participate instead of simply asking "Is it done yet?". In perfect world instead of asking "SO WHEN I CAN USE LN" you should go there, pick a task you can help with, and bring release date a minute, hour or day  closer. I am strong supporter of exactly this approach to anything I do.
