Both releases are considered a pre-requisite for doing a first 2.9 (development series) GIMP release.<\/p>\n<p>The babl library got floating point conversions optimized. Additionally, HSV and HSL color models were added, CIE LAB conversions were fixed.<\/p>\n<p>Most exciting improvements, however, are in the new GEGL release. A total of 71 new image processing operations were added: mostly these are ports of existing GIMP filters. Some of the existing operations were improved, and some got OpenCL versions.<\/p>\n<p>Another focus of this release was performance: OpenCL support is now enabled by default when detected, there&#8217;s experimental multithreading support (use GEGL_THREADS=&lt;number of threads&gt; environment variable) and experimental mipmap rendering (use GEGL_MIPMAP_RENDERING=true environment variable). There&#8217;s also a new default tile backend that writes to disk in a separate thread.<\/p>\n<p><a href=\"https:\/\/thegrid.io\/\" >The Grid<\/a> project contributed several major improvements: support for using URIs in image loaders and the loading of <a href=\"http:\/\/www.jonnor.com\/2015\/01\/imgflo-0-3\/\" >meta-operations in JSON<\/a>, created with imgflo&#8217;s online graph editor.<\/p>\n<p>GEGL&#8217;s website now features a <a href=\"http:\/\/gegl.org\/operations.html#GEGL%20operations\" >gallery<\/a> of available operations and an <a href=\"http:\/\/gegl.org\/operations.html#Gegl\" >API browser<\/a>.<\/p>\n<p>This release of GEGL was brought to you through contributions from 92 people.
