 +      - The sideband compatibility code has been removed, hence
 +        sideband connections (introduced in 0.4.11) are now mandatory.
 +      - Addblob commands can produce output.
 +      - The stat command no longer sends garbage when para_server was
 +        compiled against libgcrypt.
++      - Dependencies for gengetopt files are computed automatically.
++        This eliminates a constant source of build bugs.
