In order to make it easier to find up-to-date SRFIs, I've
revised the SRFI process to allow authors to withdraw their
SRFIs even after they have been marked final, as long as a
suitable replacement SRFI is available.  Links from the
original, now-withdrawn SRFI to the new SRFI are prominently
displayed, so it's easy to find the new version.  The
withdrawn SRFI and all its associated files are still
available — just marked withdrawn.

SRFI 40, 114, and 142 have now been withdrawn this way in
favor of their new versions (41, 128, and 151,
respectively).

Regards,

SRFI Editor
