slime-history-repl-map is no longer present. I have not spent the time to understand the new mechanism yet, and thought I'd ask here first How is the new repl history mechanism meant to be used? Perhaps I'm missing something?
as you've probably read in my previous inquiry mail, there was a refactor of the repl navigation in the official CVS and in the process some features have been removed and some bugs were introduced, especially regarding the M-r stuff. (C-g not working while reading a regexp, the double M-r feature was removed, C-up/down walks among the matches instead of uncoditionally stepping one, starting the repl history navigation does not jump to the prompt - some off the top of my head).
i've restored the removed features and fixed the bugs i've found. you can find the details here:
