| <p> |
| As of January 14, 2022, <a href="https://ignite.apache.org/">Apache Ignite</a> 2.12 has been released. You can directly check the full list of resolved <a href="https://s.apache.org/0zyi2">Important JIRA tasks</a> but here |
| let’s briefly overview some valuable improvements. |
| </p> |
| <h3 id="vulnerability-updates">Vulnerability Updates</h3> |
| <p> |
| The Apache Ignite versions lower than 2.11.1 are vulnerable to <a href="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44832">CVE-2021-44832</a> which is related to the <code>ignite-log4j2</code> module usage. |
| </p> |
| <p>The release also fixes 10+ CVE’s of various modules. See <a href="https://ignite.apache.org/releases/2.12.0/release_notes.html">release notes</a> for more details.</p> |
| <h3 id="change-data-capture">Change Data Capture</h3> |
| <p> |
| Change Data Capture (<a href="https://en.wikipedia.org/wiki/Change_data_capture">CDC</a>) is a data processing pattern used to asynchronously receive entries that have been changed on the local node so that action can be |
| taken using the changed entry. |

| <h2><a href="/blog/apache-ignite-2-11-1.html">Apache Ignite 2.11.1: Emergency Log4j2 Update</a></h2> |
| <div> |
| December 21, 2021 by Maxim Muzafarov: <a href="http://www.facebook.com/sharer.php?u=https://ignite.apache.org/blog/apache-ignite-2-11-1.html">Facebook</a><span>, </span |

| </div> |
| <div class="post__content"> |
| <p> |
| The new <a href="https://ignite.apache.org/">Apache Ignite</a> 2.11.1 is an emergency release that fixes <a href="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44228">CVE-2021-44228</a>, |
| <a href="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-45046">CVE-2021-45046</a>,<a href="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-45105">CVE-2021-45105</a> related to the ignite-log4j2 module |
| usage. |
| </p> |
| <h3 id="apache-ignite-with-log4j-vulnerability">Apache Ignite with Log4j Vulnerability</h3> |
| <p>All the following conditions must be met:</p> |
| <ul> |
| <li>The Apache Ignite version lower than 2.11.0 is used (since these vulnerabilities are already fixed in 2.11.1, 2.12, and upper versions);</li> |
| <li>The <code>ignite-logj42</code> is used by Apache Ignite and located in the <code>libs</code> directory (by default it is located in the <code>libs/optional</code>directory, so these deployments are not affected);</li> |
| <li> |
| The Java version in use is older than the following versions: <code>8u191</code>, <code>11.0.1</code>. This is due to the fact that later versions set the JVM property |
| <code>com.sun.jndi.ldap.object.trustURLCodebase</code> to <code>false</code> by default, which disables JNDI loading of classes from arbitrary URL code bases. |
| </li> |
| </ul> |
| <p>NOTE: Relying only on the Java version as a protection against these vulnerabilities is very risky and has not been tested.</p> |

| <p> |
| The new <a href="https://ignite.apache.org/">Apache Ignite</a> 2.11 was released on September 17, 2021. It can be considered to be a greater extent as a stabilization release that closed a number of technical debts of the |
| internal architecture and bugs. Out of more than 200 completed tasks, 120 are bug fixes. However, some valuable improvements still exist, so let's take a quick look at them together. |
| </p> |
| <h3 id="thin-clients">Thin Clients</h3> |
| <p> |
| Partition awareness is enabled by default in the 2.11 release and allows thin clients to send query requests directly to the node that owns the queried data. Without partition awareness, an application executes all queries |
| and operations via a single server node that acts as a proxy for the incoming requests. |
| </p> |
| <p> |
| The support of <a href="https://ignite.apache.org/docs/latest/thin-clients/java-thin-client#cache-entry-listening">Continuous Queries</a>added to the java thin client. For the other supported features, you can check - the |
| <a href="https://cwiki.apache.org/confluence/display/IGNITE/Thin+clients+features">List of Thin Client Features</a>. |
