I've just published draft #8 of SRFI 144.  It was submitted
by Will Clinger, co-author of the SRFI.

  <https://srfi.schemers.org/srfi-144/>

Here are Will's comments on the latest changes for this
draft:

  Changed the Bessel functions to take their arguments in
  the same order as the C functions jn and yn, and noted
  that those functions are not part of the C99 standard but
  are instead X/Open System Interfaces Extensions to that
  standard.

  Also changed the specification and implementation of
  make-fllog-base to require the base be greater than 1.0.

  This should become draft #8, but I left that change for
  the editor.  I believe these should be the last changes
  necessary before SRFI 144 becomes final.

Here are all the commits since the previous draft:
