 Code changes:
-
 * <<Server Control API>>: `/nsm/server/list` chain of single OSC messages, one for each session,
     is now finalized with sending and empty string "" as session name. Previously this was just
     a symbolically irrelevant console message `"Done."`
-* unstable `/nsm/gui` protocol: Send client status after a GUI attaches to running server. This
-    was not happening before, but it was the intention. It was just broken in nsmd.cpp. This alone
-    would only require API_VERSION_PATCH increment, but we are already incrementing minor.
-* unstable `/nsm/gui` protocol: Send label "launch error!" when a program is added (or loaded) that
-    does not exist in $PATH. This requires no adaptation of any client, server or GUI because labels
-    are arbitrary already and this is not meant for automatic parsing, but as user information.
 * Replies to `/nsm/server/save` etc. will now be sent back to the sender and not falsely to the last
    client who replied to `/nsm/client/save`.  This alone would only require API_VERSION_PATCH
    increment, but we are already incrementing minor.
 * <<Server Control API>>: `/nsm/server/add` was replying with an undocumented error code on success.
    Instead, as this document always specificed, it now sends `"/reply", path, "Launched."`.
    Again, this would have been just API_VERSION_PATCH on its own.
