Nice work! I noted a couple of typos :
- documention should be documentation
- miss behaviour should be misbehaviour.

Subject: a draft for the top of the NEWS for 2.0.12
Here below a draft for the top of the NEWS file for Guile 2.0.12
It needs review, in particular the 'Notable changes - Goops entry',
see FIXME in the text.

* Changes in 2.0.12 (since 2.0.11):
** Notable changes
Guile 2.0.12 needs libunistring >= 0.9.3
This check is now part of the configure step.
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
(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
*** 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
*** 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
*** 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:
- It makes the reader case sensitive.
- It disables the recognition of keyword syntax in conflict with the
R6RS (and R5RS).
- It enables the `square-brackets', `hungry-eol-escapes' and
`r6rs-hex-escapes' reader options.
*** SRFI-14 character data set
SRFI-14 character data set has been regenerated for Unicode 8.0.0.
*** Web modules
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.
The following 2 new procedures have been added: 'string-utf8-length' and
'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
'write' has been optimized: this shows a 19% improvement on the "string
without escapes" micro-benchmark of 'write.bm', and 12% on "string with
'read-string' speed up: this yields a 20% improvement on the
'scm_string_hash' has been deprecated.
'scm_read_string_like_syntax' now accept "\(" as equivalent to "(".
Tow new macros have been added: 'SCM_VALIDATE_SIZE_COPY' and
*** New Module
Add (ice-9 unicode) module.
Functionalities have been added to disable automatic finalization: see
the (Smobs) documentation node for the details and new functions.
'EXIT_SUCCESS' and 'EXIT_FAILURE' added and documented.
The following ARM target have been added: "arm.*eb", "^aarch64.*be", and
