 // CHANGELOG
 // (minor and older changes stripped away, please see git history for details)
+//  2026-10-01: OpenGL: Avoid querying glGetIntegerv(GL_CLIP_ORIGIN) again when using DrawCallback_ResetRenderState. (#2186, #3998, #3146, #3143, #8640)
 //  2026-09-17: OpenGL: Added support for platform_io.DrawCallback_SetSamplerFromTex. (#9378)
 //  2026-09-07: OpenGL: Round framebuffer dimensions to the nearest integer instead of truncating them. (#9538, 9515, #8628)
 //  2026-07-15: OpenGL: Backup and restore GL_UNPACK_ROW_LENGTH and GL_UNPACK_ALIGNMENT in UpdateTexture() to avoid corrupting caller GL state. (#8802, #9473)
