We are pleased to announce the release of Guile 1.7.2. This is a
|
|
'technology preview' for the upcoming Guile 1.8. It can be found
|
|
here:
|
|
|
|
ftp://alpha.gnu.org/gnu/guile/guile-1.7.2.tar.gz
|
|
|
|
Its MD5 checksum is
|
|
|
|
7fabb64198993e971f65a27846202388 guile-1.7.2.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".
|
|
|
|
Specifically, libguile has not yet been reviewed for thread-safeness.
|
|
|
|
We are releasing it anyway to start testing the new features, and to
|
|
get feedback about how well Guile actually behaves in a multi-threaded
|
|
setting.
|
|
|
|
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 interesting entries:
|
|
|
|
Changes since 1.7.1:
|
|
|
|
* There is a new way to initalize Guile that allows one to use Guile
|
|
from threads that have not been created by Guile.
|
|
|
|
* Mutexes and condition variables are now always fair. A recursive
|
|
mutex must be requested explicitely.
|
|
|
|
* The low-level thread API has been removed.
|
|
|
|
* There is a new way to access all kinds of vectors and arrays from
|
|
C that is efficient and thread-safe.
|
|
|
|
* The concept of dynamic roots has been factored into continuation
|
|
barriers and dynamic states.
