The release 2.5 of the Sauter tools to generate true sized fonts contains 
the following news:

* Support for LaTeX2e up to at least 1998/06/01. fontmath.cfg
  now reads fontmath.ltx, so it should be in sync with whatever
  version of LaTeX is used. fonttext.cfg can handle both lower case and
  mixed case names of the encoding definition files. Added `magstep 6
  and 7' sizes (29.86 pt and 35.83 pt) to saut*.fd, to bring them in
  line with latex/base/t1cmr.fd.

* A new directory make-mf with tex files for generating metafont files,
  replacing the msdos and unix batch files.

* Use rounded \magstep sizes everywhere now, both in make-mf
  and for the AMS symbol fonts, bbm fonts and rsfs fonts
  contributed by Hubert Holin; recomputed holin/ready-mf/*
  with the new sizes.

* A new maintainer

* No change in the fonts themselves.

Unfortunately, changing all magstep sizes to rounded sizes
(10.95, [..] 20.74, 24.88, 29.86) breaks compatibility.
But the problem is, that the compatibility was broken already:
the files under ready-mf used rounded magstep sizes already,
the files under holin/ready-mf did not, the VMS batch file did
produce rounded sizes, the unix and msdos batch files did not,
teTeX's mktexmf will generate rounded sizes (apart from the 11 pt,
at the moment), etc.
    So the current changes might lead lead to checksum mismatches
between old and new .tfm and .pk files, but at least the system
is consistent now.
    For who wants to change back to the old magstep sizes, they
were 10.954451, 20.736, 24.8832, and 29.8685984 
(which should have been 29.85984).
