The update 18 frequency is irregular and dependent on the accumulated backlog of 19 issues, up to several times per year. </p> 20 21<p> While Khronos publishes older (non-current) Specifications such as 22 OpenGL 4.5 or OpenGL ES 3.0, such Specifications are usually <b>not</b> 23 updated in response to issues and bugs unless there's a compelling 24 reason. One such compelling reason has been to update older OpenGL ES 25 Specifications on which WebGL is based, in response to requests from the 26 WebGL Working Group. </p> 27 28<h2> Extension Updates </h2> 29 30<p> Khronos-approved (<tt>ARB</tt>, <tt>OES</tt>, or <tt>KHR</tt> vendor 31 suffixed) extensions are usually updated when corresponding changes are 32 made to a core Specification, but with some time lag. </p> 33 34<p> This is a recent policy. Older bug fixes to core Specifications have not 35 always been back-ported to the corresponding extensions, and we are 36 unlikely to perform this exercise for closed issues and bugs without 37 compelling reason. </p> 38 39<p> We will tag each Khronos-approved extension with a link to this policy 40 document and a recommendation to refer to the current core Specification 41 for the latest wording. </p> 42 43<?php include_once("../../../assets/static_pages/khr_page_bottom.php"); ?> 44</body> 45</html> 46
