-** The #!r6rs directive now influences read syntax
+*** Dependencies
+
+Guile 2.0.12 needs libunistring >= 0.9.3
+This check is now part of the configure step.
+
+*** Goops
+
+Two major changes have been made:
+
+1- #:init-value on class-allocated slots: allocating an instance of a
+class with a #:class or #:each-subclass slot allocation should not
+re-initialize the class-allocated slot.
+
+2- accessor methods only apply to subclasses with their slot
+
+FIXME
+(a) let users know that it will break Goops user code relying on
+previsouly inherited getters, setters and accessors ... (b) why this: so
+that Guile 2.x.x behave like guile-1.8 wrt Goops. But the full picture
+is rather strange, and will be (re)fixed soon, see this discussion
+http://thread.gmane.org/gmane.lisp.guile.user/11218/focus=11813 for some
+details.
+ENDFIXME
+
+*** FFI: Add support for functions that set 'errno'
+
+When accessing POSIX functions from a system's libc via Guile's dynamic
+FFI, you commonly want to access the ‘errno’ variable to be able to
+produce useful diagnostic messages.
+
+This is now possible, check the Guile's dynamic FFI documentation for
+the details, in paticular the following entries have been updated
+accordingly: pointer->procedure, scm_pointer_to_procedure and
+scm_pointer_to_procedure_with_errno.
+
+*** Add SRFI-25 implementation
+    
+Adds an implementation of SRFI 25 on top of Guile's native arrays. The
+implementation does not introduce a disjoint type; Guile arrays and
+SRFI-25 arrays can be used interchangably, though with different, partly
+conflicting APIs.
+
+*** Add SRFI-28 implementation
+
+Adds an implementation of SRFI 28 Basic Format Strings.
+
+*** The #!r6rs directive now influences read syntax
 
 The #!r6rs directive now changes the per-port reader options to make
 Guile's reader conform more closely to the R6RS syntax. In particular:
@@ -19,12 +65,154 @@ Guile's reader conform more closely to the R6RS syntax. In particular:
 - It enables the `square-brackets', `hungry-eol-escapes' and
   `r6rs-hex-escapes' reader options.
 
-* Bug fixes
+*** SRFI-14 character data set
 
-** Don't replace + with space when splitting and decoding URI paths
+SRFI-14 character data set has been regenerated for Unicode 8.0.0.
 
-See the documentation for `uri-decode', for more on the new
+*** Web modules
-`#:decode-plus-to-space?' keyword argument.
+
+The (web server) module now exports 'server-impl' procedures, (web server
+http) exports the 'http' server implementation.
+
+Also, http location header accepts URI-reference, not just absoluteURIs.
+
+*** Strings
+
+The following 2 new procedures have been added: 'string-utf8-length' and
+'scm_c_string_utf8_length'.
+
+'string-hash' has been optimized: this yields a 50% improvement on the
+"narrow string" benchmark of 'hash.bm', 41% on "wide string", and 76% on
+"long string".
+
+'write' has been optimized: this shows a 19% improvement on the "string
+without escapes" micro-benchmark of 'write.bm', and 12% on "string with
+escapes".
+
+'read-string' speed up: this yields a 20% improvement on the
+"read-string" benchmark.
+
+'scm_string_hash' has been deprecated.
+
+'scm_read_string_like_syntax' now accept "\(" as equivalent to "(".
+
+*** Libguile
+
+Tow new macros have been added: 'SCM_VALIDATE_SIZE_COPY' and
+SCM_NUM2SIZE.
+
+*** New Module
+
+Add (ice-9 unicode) module.
+
+*** SMOBs
+
+Functionalities have been added to disable automatic finalization: see
+the (Smobs) documentation node for the details and new functions.
+
+*** Posix
+
+'EXIT_SUCCESS' and 'EXIT_FAILURE' added and documented.
+
+*** Architectures
+
+The following ARM target have been added: "arm.*eb", "^aarch64.*be", and
+"aarch64".
