GEGL only has released development snapshots thus far. Odd micro versions are
from SVN whilst even micro numbers indicate released snapshots.

Changes in GEGL 0.0.20
⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺
 • Build and code clean ups and fixes.
 • RAW loader using libopenraw.
 • GeglBuffer
   • Linear buffer support, amongst other things enabling GeglBuffer API access
     to external linear buffers in memory.
   • Reworked samplers using a shared caching neighbourhood infrastructure.
   • YAFR - a new resampler contributed by Nicolas Robidoux.
 • GeglVector
   • Added SVG parsing capability (no serialisation yet).
 • GeglOperations
   • Marked user visible strings for translation.
   • Added a fill operation that renders a path.

Changes in GEGL 0.0.18
⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺
 • Configuration both from commandline arguments and at runtime.
 • GeglBuffer
   • New raw tiled raster file format, used both as swap and stored buffers.
   • Sharing between processes through synced swap.
   • Babl powered scan iteration infrastructure for efficient access.
   • Cubic and lanczos samplers re-enabled.
 • Operations
   • Use scan iterator for point-filter, point-composer and point-render base
     classes internally for minimal amount of copies.
   • Optimized variants of some point and compositing operations reimplemented
     using a new data type /g4float/ that allows writing CPU agnostic vectorized
     code for GCC.
   • New temporal filter base class, for operations operating on color values from
     neighbouring frames in a video stream.
   • Autogenerated operation reference installed for use with devhelp.
   • New operations: write-buffer, v4l, color-temperature.

Changes in GEGL 0.0.16
⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺
 • Install headers for development of external operation plug-ins.
 • Added rowstride argument to gegl_buffer_set ()
 • Made it possible for sink operations to do chunkwise processing
   through GeglProcessor.
   when processed using a GeglProcessor.
 • constification of GeglRectangles and babl formats.
 • Build and dist fixes, plugged annoying buffer leaks, GEGL now
   also works on OSX

Changes in GEGL 0.0.14
⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺
 • Relicensed under LGPLv3+.
 • Per node caches (faster recomputation when properties of nodes in
   composition change)
 • Sampler framwork for interpolation.
 • Modified API for retrieving scaled buffers gegl_node_blit / gegl_buffer_get.
 • Renamed XML serialization and parsing API to be descendants of GeglNode.
 • Progress monitoring for GeglProcessor
 • New operation base class GeglOperationAreaFilter
 • API reference installed and browsable using devhelp.
 • New operations: ff-load, mono-mixer, contrast-curve, save-pixbuf,
   compositing ops from SVG-1.2 draft, value-invert, convert-format,
   bilateral-filter, snn-mean
