[Larceny-users] ANN: Larceny v0.963 "Fluoridation" (yet another bug fix release)

[William D Clinger]

Larceny and Petit Larceny v0.963 are now available
for download at

    http://larceny.ccs.neu.edu/

Larceny v0.963 fixes about 20 bugs in the recent
v0.962 release that were identified by (or with
the help of) the PLT Scheme R6RS test suite that
Matthew Flatt announced in comp.lang.scheme one
week ago yesterday.

Larceny v0.963 still fails 45 of 8843 tests in
revision 10978 of the R6RS test program.  These
failures are confined to 4 of the 24 standard
libraries tested, two of which have one failure
each.  Of the 45 failures, 35 occur within
(rnrs io ports), and correspond to unimplemented
or deprecated features of that library.  Most
other test failures involve negative zero or
branch cuts in inexact arithmetic.

We believe Larceny implements the most important
99.5% of the R6RS, but we will continue to make
improvements.  Thank you for your patience and
support.

We must also thank Matthew Flatt for making his
excellent R6RS test program available to other
implementors of the R6RS.
