+
+GEGL-0.1.0 2009-07-01
+---------------------
+
+- Renamed gegl:load-buffer to gegl:buffer-source and gegl:save-buffer
+  to gegl:buffer-sink (but the old names still work)
+- Represent colors using doubles instead of floats (this change is
+  independent from internal processing)
+- Removed the GTK+ UI parts of the gegl binary and turned gegl into a
+  pure command line tool (which can still visualize stuff with help
+  help the SDL based display operation)
+- Consider {x=G_MININT/2, y=G_MININT/2, width=G_MAXINT, height=G_MAXINT}
+   as the only valid region in which processing may occur. Processing
+   outside of this region is undefined behaviour.
+- Added support for storing allocation stack traces for GeglBuffers
+  so that debugging buffer leaks becomes much easier
+- Made small changes and cleanups of the public API, e.g.
+   - Removed gegl_node_adapt_child()
+   - Made GeglConfig an explicit object
+   - Removed most of the ifdeffed stuff to mask away internal
+     structures
+   - Added gegl_rectangle_infinite_plane() and
+     gegl_rectangle_is_infinite_plane()
+- Added new sampler GeglSamplerSharp
+- Added format property to gegl:buffer-sink
+- Cleaned up and made gegl:introspect work again
+- Add a bunch of test cases using the automake test system (make check)
+  and also port buffer tests to automake
+- General cleanups, bug fixes, increased robustness and improved
+  documentation

+   - gegl:src-in - deal correctly with extens.
+   - gegl:path - new op covering the stroke/fill needs of SVG.
+   - deprecated gegl:shift, the affine family of operations now
+     uses the same fast code paths for integer translations.

+  using a new data type /g4float/ that allows writing CPU agnostic vectorized
+  code for GCC.
