** New module (ice-9 rdelim).
This module requires SLIB to be installed and available from Guile.
+** New module (ice-9 buffered-input)
+
+This module provides procedures to construct an input port from an
+underlying source of input that reads and returns its input in chunks.
+The underlying input source is a Scheme procedure, specified by the
+caller, which the port invokes whenever it needs more input.
+
+This is useful when building an input port whose back end is Readline
+or a UI element such as the GtkEntry widget.
+
+** Documentation
+
+The reference and tutorial documentation that was previously
+distributed separately, as `guile-doc', is now included in the core
+Guile distribution. The documentation consists of the following
+manuals.
+
+- The Guile Tutorial (guile-tut.texi) contains a tutorial introduction
+ to using Guile.
+
+- The Guile Reference Manual (guile.texi) contains (or is intended to
+ contain) reference documentation on all aspects of Guile.
+
+- The GOOPS Manual (goops.texi) contains both tutorial-style and
+ reference documentation for using GOOPS, Guile's Object Oriented
+ Programming System.
+
+- The Revised^4 and Revised^5 Reports on the Algorithmic Language
+ Scheme (r4rs.texi and r5rs.texi).
+
+See the README file in the `doc' directory for more details.

* Changes to the stand-alone interpreter
** Evaluation of "()", the empty list, is now an error.
* Changes to Scheme functions and syntax
+** The empty combination is no longer valid syntax.
+
+Previously, the expression "()" evaluated to the empty list. This has
+been changed to signal a "missing expression" error. The correct way
+to write the empty list as a literal constant is to use quote: "'()".
+
+** Auto-loading of compiled-code modules is deprecated.
+
+Guile used to be able to automatically find and link a shared
+libraries to satisfy requests for a module. For example, the module
+`(foo bar)' could be implemented by placing a shared library named
+"foo/libbar.so" (or with a different extension) in a directory on the
+load path of Guile.
+
+This has been found to be too tricky, and is no longer supported.
+What you should do instead now is to write a small Scheme file that
+explicitly calls `dynamic-link' to load the shared library and
+`dynamic-call' to initialize it.
+
+The shared libraries themselves should be installed in the usual
+places for shared libraries, with names like "libguile-foo-bar".
+
+For example, place this into a file "foo/bar.scm"
+
+ (define-module (foo bar))
+
+ (dynamic-call "foobar_init" (dynamic-link "libguile-foo-bar"))
+
+The file name passed to `dynamic-link' should not contain an
+extension. It will be provided automatically.
+
** The module system has been made more disciplined.
The function `eval' will now save and restore the current module
Set or get the hostname of the machine the current process is running
on.
+** New function: mkstemp! tmpl
+
+mkstemp creates a new unique file in the file system and returns a
+new buffered port open for reading and writing to the file. TMPL
+is a string specifying where the file should be created: it must
+end with `XXXXXX' and will be changed in place to return the name
+of the temporary file.
+
** New function: open-input-string string
Return an input string port which delivers the characters from
-`string'. This procedure, together with `open-input-string' and
+`string'. This procedure, together with `open-output-string' and
`get-output-string' implements SRFI-6.
** New function: open-output-string
Return the contents of an output string port.
-** Deprecated: close-all-ports-except. This was intended for closing
-ports in a child process after a fork, but it has the undesirable side
-effect of flushing buffers. port-for-each is more flexible.
