$static_title = 'Khronos OpenGL Specification Update Policy';
<p> This page describes policy of the Khronos OpenGL Working Group for
updating API and Shading Language Specification documents, as well as
extension documents. </p>
<p> This policy was last updated on 2019-03-13. </p>
<h2> Specification Updates </h2>
<p> The current core (OpenGL 4.6, OpenGL ES 3.2, OpenGL SC 2.0, GLSL 4.60,
GLSL ES 3.20, and GLX 1.4) documents are updated in response to issues
and bugs the OpenGL Working Group considers priorities. The update
frequency is irregular and dependent on the accumulated backlog of
issues, up to several times per year. </p>
<p> While Khronos publishes older (non-current) Specifications such as
OpenGL 4.5 or OpenGL ES 3.0, such Specifications are usually <b>not</b>
updated in response to issues and bugs unless there's a compelling
reason. One such compelling reason has been to update older OpenGL ES
Specifications on which WebGL is based, in response to requests from the
WebGL Working Group. </p>
<h2> Extension Updates </h2>
<p> Khronos-approved (<tt>ARB</tt>, <tt>OES</tt>, or <tt>KHR</tt> vendor
suffixed) extensions are usually updated when corresponding changes are
made to a core Specification, but with some time lag. </p>
<p> This is a recent policy. Older bug fixes to core Specifications have not
always been back-ported to the corresponding extensions, and we are
unlikely to perform this exercise for closed issues and bugs without
compelling reason. </p>
<p> We will tag each Khronos-approved extension with a link to this policy
document and a recommendation to refer to the current core Specification
for the latest wording. </p>
