*** proof-shell-process-output now sets proof-shell-last-output and
proof-shell-last-output-kind which gives clearer interface internally
and with rest of code. See docs.
+
+*** Support for "tracing" buffers added.
+ This was added for Isabelle's simplifier tracing, when a large
+ amount of output is produced during a proof for debugging.
+ The user would rather see the output as it arrives than wait
+ for a long time.
+ Experimental stage and not yet enabled for any prover.
+ See proof-shell-spill-output-regexp.
