+<p>Now that ImageMagick version 7 is released, we continue to maintain the legacy release of ImageMagick, version 6, at <a href="https://legacy.imagemagick.org/">https://legacy.imagemagick.org</a>. Learn how ImageMagick version 7 differs from previous versions with our <a href="www/porting.html">porting guide</a>.</p>
+
+<p>ImageMagick best practices <strong>strongly</strong> encourages you to configure a <a href="www/security-policy.html">security policy</a> that suits your local environment.</p>
+
+<p>As an analog to linear (RGB) and non-linear (sRGB) color colorspaces, as of ImageMagick 7.0.7-17, we introduce the LinearGray colorspace. Gray is non-linear grayscale and LinearGray is linear (e.g. -colorspace linear-gray).</p>
+
+<p>Want more performance from ImageMagick? Try these options:</p>
+
+<ul>
+<li>Add more memory to your system, see <a href="www/architecture.html#cache">the pixel cache</a>;</li>
+<li>Add more cores to your system, see <a href="www/architecture.html#threads">threads of execution support</a>;</li>
+<li>push large images to a solid-state drive, see <a href="www/architecture.html#tera-pixel">large image support</a>.</li>
+</ul>
+<p>If these options are prohibitive, you can reduce the quality of the image results. The default build is Q16 HDRI. If you disable <a href="www/high-dynamic-range.html">HDRI</a>, you use half the memory and instead of predominately floating point operations, you use the typically more efficient integer operations. The tradeoff is reduced precision and you cannot process out of range pixel values (e.g. negative). If you build the Q8 non-HDRI version of ImageMagick, you again reduce the memory requirements in half-- and once again there is a tradeoff, even less precision and no out of range pixel values. For a Q8 non-HDRI build of ImageMagick, use these <code>configure</code> script options: <code>--with-quantum-depth=8 --disable-hdri</code>.</p>
