I've posted a news 8 months ago saying that 3.0.0 will come soon.
I apologize this didn't happen. It will, I take more time to improve any last bit to make this release as clean and perfect as possible. The hardest part is the C++ API, since 3.0.0 will include an official C++ API for developing plugins, I will need to take care of this compatibility during the 3.y.z lifetime.
Unfortunately as the only one contributor and not having many feedbacks, I don't always see all these small typos or errors and need more time to improve irccd.
Anyway, irccd 3.0.0 will happen this year and I really want it to be a long term release with the best user experience.
