-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.
-
-See NEWS and the manual for more details.
+We are pleased to announce the release of Guile 1.8.0.  It can be
+found here:

+    ftp://ftp.gnu.org/gnu/guile/guile-1.8.0.tar.gz
+
+Its SHA1 checksum is

+We already know about some issues with 1.8.0, please check the mailing
+lists:

+
+The NEWS file is quite long.  Here are the most interesting entries:
+
+  Changes since 1.6:
+
+  * 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 have exact rationals, such as 1/3.
+
+  * We now use native POSIX threads for real concurrent threads.
+
+  * 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 explicitly.
+
+  * The low-level thread API has been removed.
+
+  * There is now support for copy-on-write substrings and
+    mutation-sharing substrings.
+
+  * 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.
+
+  * 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.
