+Changes in 2.1.5 (changes since the 2.1.4 alpha release):
 
 * Notable changes
-** C99 required
-
-Following Emacs, you must use a C99-capable compiler when building
-Guile.  In the future we also expect require C99 to use Guile's C
-interface, at least for `stdint' support.
-
 * New interfaces
-** Implement R6RS custom binary input/output ports
-
-See "Custom Ports" in the manual.
-
-** Implement R6RS output-buffer-mode
-** Implement R6RS bytevector->string, string->bytevector
-
-See "R6RS Transcoders" in the manual.

-** Thread-safe atomic boxes (references)
-
-See "Atomics" in the manual.
-
-** File descriptor finalizers
-
-See "Ports and File Descriptors" in the manual.
-
 * Performance improvements
-** Added unboxing support for `logxor'
-** Better integer unboxing
-
 * Incompatible changes
-** Statically scoped module duplicate handlers
-
-It used to be that if a module did not specify a #:duplicates handler,
-when a name was first referenced in that module and multiple imported
-modules provide that name, the value of the
-`default-duplicate-binding-handlers' parameter would be used to resolve
-the duplicate bindings.  We have changed so that instead a module
-defaults to the set of handlers described in the manual.  If the module
-specifies #:duplicates, of course we use that.  The
-`default-duplicate-binding-handlers' parameter now simply accesses the
-handlers of the current module, instead of some global value.
-
 * Bug fixes
-** Better MinGW support
-
-`system*' is now supported on MinGW targets.
-
-** Avoid flushing buffers on ftell
-
-Fixes regression relative to Guile 2.0.
-
-** HTTP library does not require ETag lists to be qstrings
-
-** Fix bug importing specific bindings with #:select
-
-It used to be that if #:select didn't find a binding in the public
-interface of a module, it would actually grovel in the module's
-unexported private bindings.  This was not intended and is now fixed.
-
-** Stronger thread-safety guarantees for port implementations
-
-See "I/O Extensions" in the manual for notes on threads and port
-implementations.
-
-** Fix fixnum-range checks in R6RS fixnum bitops
-   (http://bugs.gnu.org/14917)
-
-** Fix `monitor' macro
-
-** Fix bug with GUILE_INSTALL_LOCALE=1 and default port encodings
-
-If GUILE_INSTALL_LOCALE is unset in the environment or set to 1, Guile
-will call setlocale() to install the locale.  However it was neglecting
-to set the default port encoding to the locale's encoding.  This is
-fixed.

-** Various compiler bug fixes
