+Snapshot 0.5.1 (2005-06-20 Carl Worth <cworth@cworth.org>)
+==========================================================
+API changes
+-----------
+* Removed cairo_status_string(cairo_t*) and add
+  cairo_status_to_string(cairo_status_t) in its place. Code using
+  cairo_status_string can be ported forward as follows:
+
+	cairo_status (cr);
+	->
+	cairo_status_to_string (cairo_status (cr));
+
+* Removed the BAD_NESTING restriction which means that two different
+  cairo_t objects can now interleave drawing to the same
+  cairo_surface_t without causing an error.
+
+* The following functions which previously had a return type of
+  cairo_status_t now have a return type of void:
+
+	cairo_pattern_add_color_stop_rgba
+	cairo_pattern_set_matrix
+	cairo_pattern_get_matrix
+	cairo_pattern_set_extend
+	cairo_pattern_set_filter
+
+  See discussion of cairo_pattern_status below for more details.
+
+API additions
+-------------
+* Improved error handling:
+
+	cairo_status_t
+	cairo_pattern_status (cairo_pattern_t *pattern);
+
+  This snapshot expands the status-based error handling scheme from
+  cairo_t to cairo_path_t and cairo_pattern_t. It also expands the
+  scheme so that object-creating functions, (cairo_create,
+  cairo_pattern_create_*, cairo_copy_path_*), are now guaranteed to
+  not return NULL. Instead, in the case of out-of-memory these
+  functions will return a static object with
+  status==CAIRO_STATUS_NO_MEMORY. The status can be checked with the
+  functions cairo_status and cairo_pattern_status, or by direct
+  inspection of the new status field in cairo_path_t.
+
+  Please note that some objects, including cairo_surface_t and all of
+  the font-related objects have not been converted to this
+  error-handling scheme.
+
+* In addition to the above changes, a new private function has been added:
+
+	_cairo_error
+
+  This function can be used to set a breakpoint in a debugger to make
+  it easier to find programming error in cairo-using code. (Currently,
+  _cairo_error is called when any error is detected within a cairo_t
+  context, but is not called for non-cairo_t errors such as for
+  cairo_path_t and cairo_pattern_t).
+
+* Fixed cairo_path_data_t so that its enum is visible to C++ code, (as
+  cairo_path_data_type_t).
+
+Performance improvements
+------------------------
+* Made a minor performance improvement for clipping, (restrict clip
+  surface to the new intersected bounds).
+
+* Optimize rendering of a solid source pattern with a pixel-aligned
+  rectangular path to use backend clipping rather than rasterization
+  and backend compositing.
+
+* Optimize cairo_paint_with_alpha to defer to cairo_paint when alpha
+  is 1.0.
+
+Bug fixes
+---------
+* Fixed memory leak in cairo_copy_path.
+
+* A build fix for non-srcdir builds.
+
+PDF backend fixes
+-----------------
+* New support for path-based clipping.
+
+* Fix for text rotated to angles other than multiples of π/2.
+
+Win32 backend fixes
+-------------------
+* Fix for text extents.
+
+Xlib backend
+------------
+* Implemented a complex workaround for X server bug[*] related to
+  Render-based compositing with untransformed, repeating source
+  pictures. The workaround uses core Xlib when possible for
+  performance, (ie. with CAIRO_OPERATOR_SOURCE or CAIRO_OPERATOR_OVER
+  with an opaque source surface), and falls back to the pixman
+  image-based compositing otherwise.
+
+  [*] https://bugs.freedesktop.org/show_bug.cgi?id=3566
+
+* Various bug fixes, particularly in the fallback paths.
