# RETRO 12 - 2018.12

In this release, the executables have been renamed to avoid
naming conflicts with other applications and packages.

    old name       new name
    ==========     ================
    rre            retro
    embedimage     retro-embedimage
    extend         retro-extend
    muri           retro-muri
    repl           retro-repl
    ri             retro-ri
    unu            retro-unu

The addition of the new `|` prefix makes compiler macros
easier to write. Contrast:

    :IF   &[ class:macro ; immediate
    :THEN &] class:macro &choose class:word ; immediate
    
    :IF   |[ ; immediate
    :THEN |] |choose ; immediate
