<p>ImageMagick best practices <strong>strongly</strong> encourages you to configure a <a href="security-policy.html">security policy</a> that best suits your local environment.</p>

<p class="highlight">We are utilizing a new community <a target="_blank" href="https://github.com/ImageMagick/ImageMagick6/discussions">discussion</a> service. The previous <a target="_blank" href="https://imagemagick.org/discourse-server/">discourse server</a> remains available to read legacy <a target="_blank" href="https://imagemagick.org/discourse-server/~">discussions</a>.</p>

<p>We discovered a bug in the pseudo-random generator prior to ImageMagick 6.9.10-81, the first 3 values repeated because the random state was not initialized properly. As a consequence of the fix, expect a different numerical sequence when seeding (-seed).</p>
|
||
|
|
|
||
|
|
|
||
|
|
<p>As an analog to linear (RGB) and non-linear (sRGB) color colorspaces, as of ImageMagick 6.9.9-29, we introduce the LinearGray colorspace. Gray is non-linear grayscale and LinearGray is linear (e.g. -colorspace linear-gray).</p>
|

|
||
|
|
<p>ImageMagick <a href="https://imagemagick.org">version 7</a> has been released. We encourage you to migrate your workstreams to version 7. However, we recognize a significant version 6 user community. As such, the ImageMagick development team is committed to maintain, but not enhance, version 6 at least until 2028 and possibly beyond.</p>
|
||
|
|
|
||
|
|
<p>The ImageMagick development process ensures a stable API and <a href="https://abi-laboratory.pro/tracker/timeline/imagemagick/">ABI</a>. Before each ImageMagick release, we perform a comprehensive security assessment that includes <a href="https://github.com/google/sanitizers/wiki/AddressSanitizer">memory error</a>, <a href="https://github.com/google/sanitizers/wiki/ThreadSanitizer">thread data race</a> detection, and continuous <a href="https://github.com/google/oss-fuzz">fuzzing</a> to detect and prevent security vulnerabilities.</p>
|
||
|

|
|
<p>Want more performance from ImageMagick? Try these options:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>add more memory to your system, see <a href="architecture.html#cache">the pixel cache</a>;</li>
|
||
|
|
<li>add more cores to your system, see <a href="architecture.html#threads">threads of execution support</a>;</li>
|
||
|
|
<li>reduce lock contention with the <a href="http://goog-perftools.sourceforge.net/doc/tcmalloc.html">tcmalloc</a> memory allocation library;</li>
|
||
|
|
<li>push large images to a solid-state drive, see <a href="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. If you instead use a Q8 build, you use half the memory The tradeoff is reduced precision. For a Q8 build of ImageMagick, use this <code>configure</code> script option: <code>--with-quantum-depth=8</code>.</p>
