    GLext.h updates: how often?

    Looking over the latest glext header (version 29, 6/20/05) I noticed that DEPTH24_STENCIL8_EXT was missing, which is part of the more recent EXT_packed_depth_stencil extension.

    So I was just wondering if there's any rhyme or reason to the updates, or is it just a question of the prevailing winds?

    No biggie, just curious if there's an official stance on this at all.

    When a new extensions comes up or when a new GL version comes up. GL 2.1 spec has been released so it won't be long.
    PBO is core. sRGB textures. Non square matrix in GLSL.

    PBO and sRGB means new defines.
    nVidia has annouced they will release a 2.1 driver soon.

    an open source GLU replacement library. Much more modern than GLU.
    float matrix[16], inverse_matrix[16];
    glhLoadIdentityf2(matrix);
    glhTranslatef2(matrix, 0.0, 0.0, 5.0);
    glhRotateAboutXf2(matrix, angleInRadians);
    glhScalef2(matrix, 1.0, 1.0, -1.0);
    glhQuickInvertMatrixf2(matrix, inverse_matrix);
    glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
    glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);

    I just updated the registry with a glext.h containing OpenGL 2.1 interfaces. We had some behind the scene infrastructure changes that were delaying updates for a while, but have setup autoupdates out of the internal Khronos Subversion tree now. The nominal answer to "when does it get updated" is "when someone submits new extensions for the registry", but there is always some lag time.
