Release notes for version 1.3
- Additions:
-
A collection of libraries implementing the Concurrent ML
model for concurrent programming has been added; it is
compatible to the CML libraries in Sunterlib. See the
documentation for details.
-
Support for SRFIs 34-36 ("Exception handling for programs",
"Conditions", "I/O conditions") has been added. This is in
the
conditions, exceptions, and i/o-conditions structures,
for which the srfi-34, srfi-35, and srfi-36 structures are
essentially aliases. A bridging infrastructure between the
old condition system and the new one translates condition
objects back and forth, hopefully transparently for the
user.
-
A new infrastructure for dynamically loading external
libraries from shared objects has been added; check the
manual for details. The old infrastructure is still
presented, but is unsupported on Windows and will be
removed in a future release.
-
The
S48_GC_UNPROTECT_GLOBAL macro has been added, which
allows to remove a root added by S48_GC_PROTECT_GLOBAL.
The Scheme 48 header files should now be compileable by a
C++ compiler.
-
An experimental Windows port has been added.
- Changes:
-
The HTML manual is now generated with tex2page.
-
A number of changes to the VM to support the (future)
native-code compiler have been made.
-
The PreScheme type rule for
if is now more strict, thus
disallowing code that would lead to invalid C output.
(This fixes a bug reported by Markus Ziegler.)
- Bug fixes:
-
The
traverse structure for displaying heap statistics has
been re-enabled.
-
A number of misues of
call-error have been corrected
(reported by Taylor Campbell).
-
The
value-pipes package works again
(fix by Taylor Campbell).
-
In PreScheme it is now possible to shift integers by
non-constant shift widths.
-
Logical right shifts in PreScheme work now
(reported by Taylor Campbell).
-
A bug in
terminate-thread! was fixed
(reported by Taylor Campbell).
-
A bug in the implementation of
,exit-when-done was fixed.
-
A bug in the regexp-matching code that prevented matching
the empty string correctly was fixed.
-
A bug in the implementation of
string-contains from srfi-13
was fixed.
-
A bug in the implementation of
:while in srfi-42 was fixed
(submitted by Sebastian Egner).
-
Bugs in the implementations of
angle and magnitude were
fixed.
-
An obscure bug in the implementation of
apply (which was
triggered by certain instances of (apply apply ...) )
was fixed.
-
For a degenerate case of
iterate, the code was made to
conform the documentation
(reported by Taylor Campbell).
-
Various miscellaneous fixes.
Release notes for version 1.2.
