It has been announced in the Linux Mint blog than the trial packages available in Romeo have been officially moved to Hair.
What does this mean? That soon we will have available the LMDE Update Pack 4 (with updated iso). Anyway Clem warns that the job is still in progress and users of LMDE they must wait for it to finish so as not to present problems. So you know guys, good news.
It has already come out. http://blog.linuxmint.com/?p=1949
