We are pleased to announce the release of Guile 1.7.1. This is a
|
|
'technology preview' for the upcoming Guile 1.8. It can be found
|
|
here:
|
|
|
|
ftp://alpha.gnu.org/gnu/guile/guile-1.7.1.tar.gz
|
|
|
|
Its MD5 checksum is
|
|
|
|
21c9f4061166900d2926955ade0ef5cc guile-1.7.1.tar.gz
|
|
|
|
This version is guaranteed to contain serious bugs, and the publically
|
|
visible interfaces will almost certainly change before 1.8 is
|
|
released. The 1.7 releases might be termed "selected snapshots".
|
|
|
|
We are releasing it anyway to start testing the new features, and to
|
|
get feedback about how difficult or tedious it is to switch from Guile
|
|
1.6 to this series.
|
|
|
|
Ideally, you should be able to just link your program with Guile 1.7.1
|
|
instead of with Guile 1.6.x. You will get many warnings about
|
|
deprecated features, but your program should nevertheless run
|
|
correctly. If you find that this is not the case (which is quite
|
|
likely) please do not change your program yet. Instead, report the
|
|
problem to <bug-guile@gnu.org>.
|
|
|
|
The shared library major versions have been bumped compared to the 1.6
|
|
series, but they will not be bumped on binary incompatible changes
|
|
within the 1.7 series.
|
|
|
|
|
|
The NEWS file is quite long. Here are the most spectacular entries in
|
|
a condensed form:
|
|
|
|
Changes since the 1.6.x series:
|
|
|
|
- Guile is now licensed with the GNU Lesser General Public License.
|
|
|
|
- The manual is now licensed with the GNU Free Documentation License.
|
|
|
|
- We now use GNU MP for bignums.
|
|
|
|
- We now use native POSIX threads for real concurrent threads.
|
|
|
|
- There is now support for copy-on-write substrings and
|
|
mutation-sharing substrings.
|
|
|
|
- We now have exact rationals, such as 1/3.
|
|
|
|
- A new family of functions for converting between C values and
|
|
Scheme values has been added that is future-proof and thread-safe.
|
|
|
|
- The INUM macros like SCM_MAKINUM have been deprecated.
|
|
|
|
- The macros SCM_STRINGP, SCM_STRING_CHARS, SCM_STRING_LENGTH,
|
|
SCM_SYMBOL_CHARS, and SCM_SYMBOL_LENGTH have been deprecated.
|
|
|
|
- There is a new way to deal with non-local exits and re-entries in
|
|
C code, which is nicer than scm_internal_dynamic_wind.
|
|
|
|
- There are new malloc-like functions that work better than
|
|
scm_must_malloc, etc.
|
|
|
|
and most importantly
|
|
|
|
- call-with-current-continuation is now also available under the name
|
|
call/cc.
