I've just published draft #5 of SRFI 151.  It was

submitted by John Cowan, author of the SRFI.

  https://srfi.schemers.org/srfi-151

Here are John's comments on the draft:

  - [Per Takashi Kato's message,

  bitwise-copy-bit-field and

  bitwise-rotate-bit-field are now in italics in

  the Comparison of proposals section.]

  

  - There is also an editorial change about the

  changes from SRFI 142, from just one to two.

Here's the diff:
