When I launched multibit, I was alarmed to learn that the importation blockchain.info wallet export files was removed.
I created such a file (and kept a paper back-up) back in September or August of last year. Because the funds are not mine, I do not keep them on my machine. I was counting on being able to use Multibit to restore the key in the event blockchain.info ever went down or was considered unreliable for some reason.
My immediate response after seeing functionally removed is to not upgrade: upgrades have been often detrimental to the user since the 1996 WIPO "Copyright" and "Performances and Phonograms" treaties.
I then thought: "Ok, maybe there is a reason the functionality was removed if it was a 'bug fix'". I then went to the
Release Notes, then the
Multibit website looking for the source-code and bug-tracking database. I never found it. (Update: it is the "To get involved you should
fork the source code on GitHub." link). I found a link to these forums, and found the thread about how a user lost a lot of Bitcoins and complained on reddit. I searched the forum and found
this thread describing a new blockchain.info wallet import tool.
I finally found the
Blog post explaining the issue. However, the
suggested replacement tool currently just displays the message: "This document has been removed temporarily"
TL;dr: This post is mainly search-engine bait in case somebody else is confused as well.
