* 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+** The empty combination is no longer valid syntax.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
* return 0 if the request is for 0 bytes, with no end-of-file
check
+** New function: object->string OBJ
+
+Return a Scheme string obtained by printing a given object.
+
** New function: port? X
Returns a boolean indicating whether X is a port. Equivalent to
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
+`get-output-string' implements SRFI-6.
+
+** New function: open-output-string
+
+Return an output string port which collects all data written to it.
+The data can then be retrieved by `get-output-string'.
+
+** New function: get-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.
Use one of the new functions scm_remember_upto_here_1,
scm_remember_upto_here_2 or scm_remember_upto_here instead.
+** New function: scm_allocate_string
+
+This function replaces the function scm_makstr.
+
+** Deprecated function: scm_makstr
+
+Use the new function scm_allocate_string instead.
+
** New global variable scm_gc_running_p introduced.
Use this variable to find out if garbage collection is being executed. Up to
SCM_ROSTRINGP, SCM_RWSTRINGP, SCM_VALIDATE_RWSTRING, SCM_ROCHARS,
SCM_ROUCHARS, SCM_SETLENGTH, SCM_SETCHARS, SCM_LENGTH_MAX, SCM_GC8MARKP,
SCM_SETGC8MARK, SCM_CLRGC8MARK, SCM_GCTYP16, SCM_GCCDR, SCM_SUBR_DOC,
-SCM_OPDIRP, SCM_VALIDATE_OPDIR, SCM_WTA, RETURN_SCM_WTA
+SCM_OPDIRP, SCM_VALIDATE_OPDIR, SCM_WTA, RETURN_SCM_WTA, SCM_CONST_LONG,
+SCM_WNA, SCM_FUNC_NAME, SCM_VALIDATE_NUMBER_COPY,
+SCM_VALIDATE_NUMBER_DEF_COPY
Use SCM_ASSERT_RANGE or SCM_VALIDATE_XXX_RANGE instead of SCM_OUTOFRANGE.
Use scm_memory_error instead of SCM_NALLOC.
Use SCM_DIR_OPEN_P instead of SCM_OPDIRP.
Use SCM_MISC_ERROR or SCM_WRONG_TYPE_ARG instead of SCM_WTA.
Use SCM_MISC_ERROR or SCM_WRONG_TYPE_ARG instead of RETURN_SCM_WTA.
+Use SCM_VCELL_INIT instead of SCM_CONST_LONG.
+Use SCM_WRONG_NUM_ARGS instead of SCM_WNA.
** Removed function: scm_struct_init
This can be used to set an apply function to a smob type.
+** Deprecated function: scm_strprint_obj
+
+Use scm_object_to_string instead.
+
+** Deprecated function: scm_wta
+
+Use scm_wrong_type_arg, or another appropriate error signalling function
+instead.
+
\f
Changes since Guile 1.3.4:
Implements the interface to documentation strings associated with
objects.
+** New module (ice-9 time)
+
+Provides a macro `time', which displays execution time of a given form.
+
+** New module (ice-9 history)
+
+Loading this module enables value history in the repl.
+
* Changes to the stand-alone interpreter
** New command line option --debug
