 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.
+Specifically, libguile has not yet been reviewed for thread-safeness.
 
-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>.
+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 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 NEWS file is quite long.  Here are the most interesting entries:
 
-  - The INUM macros like SCM_MAKINUM have been deprecated.
+  Changes since 1.7.1:
 
-  - 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 initalize Guile that allows one to use Guile
+    from threads that have not been created by Guile.
 
-  - 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.
+  * Mutexes and condition variables are now always fair.  A recursive
+    mutex must be requested explicitely.
 
-  - There are new malloc-like functions that work better than
-    scm_must_malloc, etc.
+  * The low-level thread API has been removed.
 
-and most importantly
+  * There is a new way to access all kinds of vectors and arrays from
+    C that is efficient and thread-safe.
 
-  - call-with-current-continuation is now also available under the name
-    call/cc.
+  * The concept of dynamic roots has been factored into continuation
+    barriers and dynamic states.
