| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Over 50 improvements and fixes to the Log4j 1.x support. |
| Continued testing has shown it is a suitable replacement for Log4j 1.x in most cases.</p> |
| </li> |
| <li> |
| <p>Scripting now requires a system property be specified naming the languages the user wishes to allow. |
| The scripting engine will not load if the property isn’t set.</p> |
| </li> |
| <li> |
| <p>By default, the only remote protocol allowed for loading configuration files is HTTPS. |
| Users can specify a system property to allow others or prevent remote loading entirely.</p> |
| </li> |
| <li> |
| <p>Variable resolution has been modified so that only properties defined as properties in the configuration file can be recursive. |
| All other Lookups are now non-recursive. |
| This addresses issues users were having resolving lookups specified in property definitions for use in the <code>RoutingAppender</code> and <code>RollingFileAppender</code> due to restrictions put in place in 2.17.1.</p> |
| </li> |
| <li> |
| <p>Many other fixes and improvements.</p> |

| <li> |
| <p>Removed Message Lookups. |
| This is a hardening related to changes made to prevent CVE-2021-44228. |
| While this change is recommended, it is NOT required to fix CVE-2021-44228.</p> |
| </li> |
| <li> |
| <p>While release 2.15.0 removed the ability to resolve Lookups and log messages and addressed issues with how JNDI is accessed, the Log4j team feels that having JNDI enabled by default introduces an undue risk for our users. |
| Starting in version 2.16.0, JNDI functionality is disabled by default and can be re-enabled via the <code>log4j2.enableJndi</code> system property. |
| Use of JNDI in an unprotected context is a large security risk and should be treated as such in both this library and all other Java libraries using JNDI.</p> |
| </li> |
| <li> |
| <p>Prior to version 2.15.0, Log4j would automatically resolve Lookups contained in the message or its parameters in the Pattern Layout. |
| This behavior is no longer the default and must be enabled by specifying <code>%msg{lookup}</code>.</p> |

| <div class="paragraph"> |
| <p>This release contains a number of bug fixes and minor enhancements which are listed below.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The Log4j team has been made aware of a security vulnerability, CVE-2021-44228, that has been addressed in Log4j 2.15.0.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Log4j’s JNDI support has not restricted what names could be resolved. |
| Some protocols are unsafe or can allow remote code execution. |
| Log4j now limits the protocols by default to only java, ldap, and ldaps and limits the ldap protocols to only accessing Java primitive objects by default served on the local host.</p> |
| </div> |
| <div class="paragraph"> |
| <p>One vector that allowed exposure to this vulnerability was Log4j’s allowance of Lookups to appear in log messages. |
| As of Log4j 2.15.0 this feature is now disabled by default. |
| While an option has been provided to enable Lookups in this fashion, users are strongly discouraged from enabling it.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Users who cannot upgrade to 2.15.0 can mitigate the exposure by:</p> |
| </div> |
| <div class="olist arabic"> |
| <ol class="arabic"> |
| <li> |
| <p>Users of Log4j 2.10 or greater may add <code>-Dlog4j.formatMsgNoLookups=true</code> as a command line option or add <code>log4j.formatMsgNoLookups=true</code> to a <code>log4j2.component.properties</code> file on the classpath to prevent lookups in log event messages.</p> |
| </li> |
| <li> |
| <p>Users since Log4j 2.7 may specify <code>%{nolookups}</code> in the <code>PatternLayout</code> configuration to prevent lookups in log event messages.</p> |
| </li> |
| <li> |
| <p>Remove the <code>JndiLookup</code> and <code>JndiManager</code> classes from the <code>log4j-core</code> JAR. |
| Removal of the <code>JndiManager</code> will cause the <code>JndiContextSelector</code> and <code>JMSAppender</code> to no longer function.</p> |
| </li> |
| </ol> |
| </div> |
| <div class="paragraph"> |
| <p>Due to a break in compatibility in the SLF4J binding, Log4j now ships with two versions of the SLF4J to Log4j adapters. |
| <code>log4j-slf4j-impl</code> should be used with SLF4J 1.7.x and earlier and <code>log4j-slf4j18-impl</code> should be used with SLF4J 1.8.x and later. |
| SLF4J-2.0.0 alpha releases are not fully supported. |
| See <a href="https://issues.apache.org/jira/browse/LOG4J2-2975">LOG4J2-2975</a> and <a href="https://jira.qos.ch/browse/SLF4J-511">SLF4J-511</a>.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Some of the new features in Log4j 2.15.0 include:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Support for Arbiters, which are conditionals that can enable sections of the logging configuration for inclusion or exclusion. |
| In particular, <code>SpringProfile</code>, <code>SystemProperty</code>, Script, and Class Arbiters have been provided that use the Spring profile, System property, the result of a script, or the presence of a class respectively to determine whether a section of configuration should be included.</p> |
| </li> |
| <li> |
| <p>Support for Jakarta EE 9. |
| This is functionally equivalent to Log4j’s <code>log4j-web</code> module but uses the Jakarta project.</p> |
| </li> |
| <li> |
| <p>Various performance improvements.</p> |
| </li> |
| </ul> |
| </div> |
| <div class="paragraph"> |
| <p>Key changes to note:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Prior to this release Log4j would automatically resolve Lookups contained in the message or its parameters in the Pattern Layout. |
| This behavior is no longer the default and must be enabled by specifying <code>%msg{lookup}</code>.</p> |
| </li> |
| <li> |
| <p>The JNDI Lookup has been restricted to only support the java, ldap, and ldaps protocols by default. |
| LDAP also no longer supports classes that implement the <code>Referenceable</code> interface and restricts the Serializable classes to the Java primitive classes by default and requires an allow list to be specified to access remote LDAP servers.</p> |
| </li> |
| </ul> |
| </div> |
| <div class="paragraph"> |
| <p>The Log4j 2.15.0 API, as well as many core components, maintains binary compatibility with previous releases.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Apache Log4j 2.15.0 requires a minimum of Java 8 to build and run. |
| Log4j 2.12.1 is the last release to support Java 7. |
| Java 7 is no longer supported by the Log4j team.</p> |
| </div> |

| <h3 id="release-notes-2-15-0-added">Added</h3> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Add support for US-style date patterns and micro/nano seconds to FixedDateTime. (<a href="https://issues.apache.org/jira/browse/LOG4J2-2885">LOG4J2-2885</a>)</p> |
| </li> |
| <li> |
| <p>Add BasicAsyncLoggerContextSelector equivalent to AsyncLoggerContextSelector for applications with a single LoggerContext. This selector avoids classloader lookup overhead incurred by the existing AsyncLoggerContextSelector. (<a href="https://issues.apache.org/jira/browse/LOG4J2-2940">LOG4J2-2940</a>)</p> |
| </li> |
| <li> |
| <p>Context selectors are aware of their dependence upon the callers ClassLoader, allowing basic context selectors to avoid the unnecessary overhead of walking the stack to determine the caller’s ClassLoader. (<a href="https://issues.apache.org/jira/browse/LOG4J2-2940">LOG4J2-2940</a>)</p> |
| </li> |
| <li> |
| <p>Add support for Jakarta EE 9 (Tomcat 10 / Jetty 11) (<a href="https://issues.apache.org/jira/browse/LOG4J2-2978">LOG4J2-2978</a>)</p> |
| </li> |
| <li> |
| <p>Add plugin support to JsonTemplateLayout. (<a href="https://issues.apache.org/jira/browse/LOG4J2-3004">LOG4J2-3004</a>)</p> |

| </li> |
| <li> |
| <p>Allow MapMessage and ThreadContext attributes to be prefixed. (<a href="https://issues.apache.org/jira/browse/LOG4J2-3049">LOG4J2-3049</a>)</p> |
| </li> |
| <li> |
| <p>Allow AdditionalFields to be ignored if their value is null or a zero-length String. (<a href="https://issues.apache.org/jira/browse/LOG4J2-3050">LOG4J2-3050</a>)</p> |
| </li> |
| <li> |
| <p>Add CaseConverterResolver to JsonTemplateLayout. (<a href="https://issues.apache.org/jira/browse/LOG4J2-3051">LOG4J2-3051</a>)</p> |

| </li> |
| <li> |
| <p>Add missing slf4j-api singleton accessors to log4j-slf4j-impl (1.7) StaticMarkerBinder and StaticMDCBinder. This doesn’t impact behavior or correctness, but avoids throwing and catching NoSuchMethodErrors when slf4j is initialized and avoids linkage linting warnings. (<a href="https://issues.apache.org/jira/browse/LOG4J2-3133">LOG4J2-3133</a>)</p> |
| </li> |
| <li> |
| <p>Avoid ThreadLocal overhead in RandomAccessFileAppender, RollingRandomAccessFileManager, and MemoryMappedFileManager due to the unused setEndOfBatch and isEndOfBatch methods. The methods on LogEvent are preferred. (<a href="https://issues.apache.org/jira/browse/LOG4J2-3141">LOG4J2-3141</a>)</p> |
| </li> |
| <li> |
| <p>Prefer string.getBytes(Charset) over string.getBytes(String) based on performance improvements in modern Java releases. (<a href="https://issues.apache.org/jira/browse/LOG4J2-3144">LOG4J2-3144</a>)</p> |
| </li> |

| <li> |
| <p>Improve NameAbbreviator worst-case performance. (<a href="https://issues.apache.org/jira/browse/LOG4J2-3189">LOG4J2-3189</a>)</p> |
| </li> |
| <li> |
| <p>Allow fractional attributes for size attribute of SizeBasedTriggeringPolicy. (<a href="https://issues.apache.org/jira/browse/LOG4J2-3194">LOG4J2-3194</a>)</p> |
| </li> |
| <li> |
| <p>Pattern layout no longer enables lookups within message text by default for cleaner API boundaries and reduced formatting overhead. The old 'log4j2.formatMsgNoLookups' which enabled this behavior has been removed as well as the 'nolookups' message pattern converter option. The old behavior can be enabled on a per-pattern basis using '%m{lookups}'. (<a href="https://issues.apache.org/jira/browse/LOG4J2-3198">LOG4J2-3198</a>)</p> |

| <p>This release contains bugfixes and minor enhancements. |
| Some of the new features in this release are:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Log4j 2 now requires Java 8 or higher to build and run.</p> |
| </li> |
| <li> |
| <p>Experimental support for Log4j 1 configuration files. |
| See Log4j 2 Compatiblity with Log4j 1.</p> |
| </li> |
| <li> |
| <p>The Logger API has been enhanced to support a builder pattern. |
| This can dramatically improve the overhead of capturing location information. |
| See Log Builder.</p> |
| </li> |
| <li> |
| <p>Better integration with Spring Boot by providing access to Spring variables in Log4j 2 configuration files and allowing Log4j 2 system properties to be defined in the Spring configuration. |
| See Logging in the Cloud.</p> |
| </li> |
| <li> |
| <p>Support for accessing Kubernetes information via a Log4j 2 Lookup.</p> |
| </li> |
| <li> |
| <p>The Gelf Layout now allows the message to be formatted using a <code>PatternLayout</code> pattern. |
| Logging in the Cloud provides an example of this, as well as the use of the Spring and Kubernetes Lookups.</p> |
| </li> |
| </ul> |
| </div> |
| <div class="paragraph"> |
| <p>Due to a break in compatibility in the SLF4J binding, Log4j now ships with two versions of the SLF4J to Log4j adapters. |
| <code>log4j-slf4j-impl</code> should be used with SLF4J 1.7.x and earlier and <code>log4j-slf4j18-impl</code> should be used with SLF4J 1.8.x and later.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Note that the XML, JSON and YAML formats changed in the 2.11.0 release: they no longer have the <code>timeMillis</code> attribute and instead have an <code>Instant</code> element with <code>epochSecond</code> and <code>nanoOfSecond</code> attributes.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The Log4j 2.13.0 API, as well as many core components, maintains binary compatibility with previous releases.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Log4j 2.13.0 requires a minimum of Java 8 to build and run. |
| Log4j 2.3 was the last release that supported Java 6 and Log4j 2.11.2 is the last release to support Java 7.</p> |

| <div class="paragraph"> |
| <p>This release contains bugfixes and minor enhancements.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Due to a break in compatibility in the SLF4J binding, Log4j now ships with two versions of the SLF4J to Log4j adapters. |
| <code>log4j-slf4j-impl</code> should be used with SLF4J 1.7.x and earlier and <code>log4j-slf4j18-impl</code> should be used with SLF4J 1.8.x and later.</p> |
| </div> |
| <div class="paragraph"> |
| <p>As of Log4j 2.9.0, the Log4j API was modified to use <code>java.util.ServiceLoader</code> to locate Log4j implementations, although the former binding mechanism is still supported. |
| The Log4j API JAR is now a multi-release JAR to provide implementations of Java 9 specific classes. |
| Multi-release JARs are not supported by the OSGi specification so OSGi modules will not be able to take advantage of these implementations but will not lose functionality as they will fall back to the implementations used in Java 7 and 8. |
| Applications using Spring Boot must add the Multi-Release header to the JAR manifest or the Java 9+ classes will be ignored.</p> |
| </div> |
| <div class="paragraph"> |
| <p>More details on the new features and fixes are itemized below. |
| Note that some tools are not compatible with multi-release JARs and may fail trying to process class files in the <code>META-INF/versions/9</code> folder. |
| Those errors should be reported to the tool vendor.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Note that subsequent to the 2.9.0 release, for security reasons, Log4j does not process DTD in XML files. |
| If you used DTD for including snippets, you have to use XInclude or Composite Configuration instead.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Also subsequent to the 2.9.0 release, for security reasons, <code>SerializedLayout</code> is deprecated and no longer used as default in the Socket and JMS appenders. |
| <code>SerializedLayout</code> can still be used as before, but has to be specified explicitly. |
| To retain old behaviour, you have to change configuration like:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-xml" data-lang="xml"><Appenders> |

| <JsonLayout properties="true"/> |
| </Socket> |
| </Appenders></code></pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>Note that the XML, JSON and YAML formats changed in the 2.11.0 release: they no longer have the <code>timeMillis</code> attribute and instead have an <code>Instant</code> element with <code>epochSecond</code> and <code>nanoOfSecond</code> attributes.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The Log4j 2.11.2 API, as well as many core components, maintains binary compatibility with previous releases.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Log4j 2.11.2 requires a minimum of Java 7 to build and run. |
| Log4j 2.3 was the last release that supported Java 6.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Basic compatibility with Log4j 1.x is provided through the <code>log4j-1.2-api</code> component, however it does |
| not implement some of the very implementation specific classes and methods. |
| The package names and Maven <code>groupId</code> have been changed to <code>org.apache.logging.log4j</code> to avoid any conflicts with Log4j 1.x.</p> |

| <div class="paragraph"> |
| <p>This release contains new features, bugfixes and minor enhancements. |
| Some of the new features include support for the Java 9 module system, support for the new SLF4j 1.8 binding mechanism, simplification of the Log4j property naming scheme, and native support of Jetty’s logger. |
| Log4j API is now a fully compliant module while the other Log4j jars are named automatic modules.</p> |
| </div> |
| <div class="paragraph"> |
| <p>As of Log4j 2.9.0, the Log4j API was modified to use <code>java.util.ServiceLoader</code> to locate Log4j implementations, although the former binding mechanism is still supported. |
| The Log4j API JAR is now a multi-release JAR to provide implementations of Java 9 specific classes. |
| Multi-release JARs are not supported by the OSGi specification so OSGi modules will not be able to take advantage of these implementations but will not lose functionality as they will fall back to the implementations used in Java 7 and 8. |
| More details on the new features and fixes are itemized below. |
| Note that some tools are not compatible with multi-release JARs and may fail trying to process class files in the <code>META-INF/versions/9</code> folder. |
| Those errors should be reported to the tool vendor.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Note that subsequent to the 2.9.0 release, for security reasons, <code>SerializedLayout</code> is deprecated and no longer used as default in the Socket and JMS appenders. |
| <code>SerializedLayout</code> can still be used as before, but has to be specified explicitly. |
| To retain old behaviour, you have to change configuration like:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-xml" data-lang="xml"><Appenders> |
| <Socket name="socket" host="localhost" port="9500"/> |
| </Appenders></code></pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>into:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-xml" data-lang="xml"><Appenders> |
| <Socket name="socket" host="localhost" port="9500"> |
| <SerializedLayout/> |
| </Socket> |
| </Appenders></code></pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>We do, however, discourage the use of <code>SerializedLayout</code> and recommend <code>JsonLayout</code> as a replacement:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-xml" data-lang="xml"><Appenders> |
| <Socket name="socket" host="localhost" port="9500"> |
| <JsonLayout properties="true"/> |
| </Socket> |
| </Appenders></code></pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>Note that subsequent to the 2.9.0 release, for security reasons, Log4j does not process DTD in XML files. |
| If you used DTD for including snippets, you have to use XInclude or Composite Configuration instead.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The Log4j 2.11.0 API, as well as many core components, maintains binary compatibility with previous releases with the following exceptions to Log4j Core. |
| Log4j 2.11.0 moves code from <code>log4j-core</code> to several new Maven modules. |
| Dependencies to other JARs that used to be optional in <code>log4j-core</code> are now required in the new modules. |
| The code in these modules have been repackaged. |
| These changes do not affect your configuration files.</p> |

| <div class="paragraph"> |
| <p>This release contains new features, bugfixes and minor enhancements. |
| Some of the new features include support for the Java 9 module system, support for the new SLF4j 1.8 binding mechanism, simplification of the Log4j property naming scheme, and native support of Jetty’s logger. |
| Log4j API is now a fully compliant Java 9 module while the other Log4j jars are Java 9 named automatic modules.</p> |
| </div> |
| <div class="paragraph"> |
| <p>This release supports both SLF4J 1.7.x and SLF4J 1.8.x. |
| Because SLF4J 1.7.x requires implementations to include classes in the <code>org.slf4j.impl</code> package <code>log4j-sl4j-impl</code> cannot be used as a Java 9 module. |
| Support for SLF4J 1.7.x will be removed in a future release.</p> |
| </div> |
| <div class="paragraph"> |
| <p>As of Log4j 2.9.0, the Log4j API was modified to use <code>java.util.ServiceLoader</code> to locate Log4j implementations, although the former binding mechanism is still supported. |
| The Log4j API JAR is now a multi-release JAR to provide implementations of Java 9 specific classes. |
| Multi-release JARs are not supported by the OSGi specification so OSGi modules will not be able to take advantage of these implementations but will not lose functionality as they will fall back to the implementations used in Java 7 and 8. |
| More details on the new features and fixes are itemized below. |
| Note that some tools are not compatible with multi-release JARs and may fail trying to process class files in the <code>META-INF/versions/9</code> folder. |
| Those errors should be reported to the tool vendor.</p> |
| </div> |
| <div class="paragraph"> |
| <p>During testing of the release it was found that one unit test fails when run on Windows. |
| When building from source either use <code>mvn clean install -DskipTests</code> on Windows or run the build on a different operating system. |
| The unit test failure is a problem in the test, not in Log4j. |
| As always, pre-built distributions can be downloaded from <a href="http://www.apache.org/dist/logging/log4j/" class="bare">http://www.apache.org/dist/logging/log4j/</a> or the binaries JARs may be obtained from the Maven central repository.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Note that subsequent to the 2.9.0 release, for security reasons, <code>SerializedLayout</code> is deprecated and no longer used as default in the Socket and JMS appenders. |
| <code>SerializedLayout</code> can still be used as before, but has to be specified explicitly. |
| To retain old behaviour, you have to change configuration like:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-xml" data-lang="xml"><Appenders> |
| <Socket name="socket" host="localhost" port="9500"/> |
| </Appenders></code></pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>into:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-xml" data-lang="xml"><Appenders> |
| <Socket name="socket" host="localhost" port="9500"> |
| <SerializedLayout/> |
| </Socket> |
| </Appenders></code></pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>We do, however, discourage the use of <code>SerializedLayout</code> and recommend <code>JsonLayout</code> as a replacement:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-xml" data-lang="xml"><Appenders> |
| <Socket name="socket" host="localhost" port="9500"> |
| <JsonLayout properties="true"/> |
| </Socket> |
| </Appenders></code></pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>Note that subsequent to the 2.9.0 release, for security reasons, Log4j does not process DTD in XML files. |
| If you used DTD for including snippets, you have to use XInclude or Composite Configuration instead.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The Log4j 2.10.0 API, as well as many core components, maintains binary compatibility with previous releases.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Log4j 2.10.0 requires a minimum of Java 7 to build and run. |
| Log4j 2.3 was the last release that supported Java 6.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Basic compatibility with Log4j 1.x is provided through the <code>log4j-1.2-api</code> component, however it does |
| not implement some of the very implementation specific classes and methods. |
| The package names and Maven <code>groupId</code> have been changed to <code>org.apache.logging.log4j</code> to avoid any conflicts with Log4j 1.x.</p> |
| </div> |

| <p>This release contains bugfixes and minor enhancements.</p> |
| </div> |
| <div class="paragraph"> |
| <p>As of Log4j 2.9.0, the Log4j API was modified to use <code>java.util.ServiceLoader</code> to locate Log4j implementations, although the former binding mechanism is still supported. |
| The Log4j JAR is now a multi-release JAR to provide implementations of the Java 9 specific classes. |
| Multi-release JARs are not supported by the OSGi specification so OSGi modules will not be able to take advantage of these implementations but will not lose functionality as they will fall back to the implementations used in Java 7 and 8. |
| More details on the new features and fixes are itemized below.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Note that subsequent to the 2.9.0 release, for security reasons, <code>SerializedLayout</code> is deprecated and no longer used as default in the Socket and JMS appenders. |
| <code>SerializedLayout</code> can still be used as before, but has to be specified explicitly. |
| To retain old behaviour, you have to change configuration like:</p> |

| <div class="paragraph"> |
| <p>Note that subsequent to the 2.9.0 release, for security reasons, Log4j does not process DTD in XML files. |

| <div class="paragraph"> |
| <p>Basic compatibility with Log4j 1.x is provided through the <code>log4j-1.2-api</code> component, however it does |

| <p>This release contains several bugfixes and new features. |
| The new features include the ability to have the <code>RollingFileAppender</code> log directly to the archive files. |
| More details on the new features and fixes are itemized below.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Note that subsequent to the 2.6 release a minor source incompatibility was found due to the addition of new methods to the <code>Logger</code> interface. |
| If you have code that does:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-java" data-lang="java">logger.error(null, “This is the log message”, throwable);</code></pre> |

| <p>The Log4j 2.8 API, as well as many core components, maintains binary compatibility with previous releases.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Log4j 2.8 requires a minimum of Java 7 to build and run. |
| Log4j 2.3 was the last release that supported Java 6.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Basic compatibility with Log4j 1.x is provided through the <code>log4j-1.2-api</code> component, however it does |
| not implement some of the very implementation specific classes and methods. |
| The package names and Maven <code>groupId</code> have been changed to <code>org.apache.logging.log4j</code> to avoid any conflicts with Log4j 1.x.</p> |

| <p>This release contains several bugfixes and new features. |
| The new features include new logging API modules for Scala 2.10 and 2.11, and support for various non-blocking queue implementations in <code>AsyncAppender</code>. |
| Furthermore the <code>ThreadContext</code> map can now be configured to be garbage-free, and users can now inject context data from other sources than <code>ThreadContext</code>. |
| Context data values can be any <code>Object</code>, not just <code>String</code>s. |
| More details on the fixes are itemized below.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Note that subsequent to the 2.6 release a minor source incompatibility was found due to the addition of new methods to the <code>Logger</code> interface. |
| If you have code that does:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-java" data-lang="java">logger.error(null, “This is the log message”, throwable);</code></pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>or similar with any log level you will get a compiler error saying the reference is ambiguous. |
| To correct this either do:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-java" data-lang="java">logger.error(“This is the log message”, throwable);</code></pre> |

| <p>The Log4j 2.7 API, as well as many core components, maintains binary compatibility with previous releases.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Log4j 2.7 requires a minimum of Java 7 to build and run. |
| Log4j 2.3 was the last release that supported Java 6.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Basic compatibility with Log4j 1.x is provided through the <code>log4j-1.2-api</code> component, however it does |
| not implement some of the very implementation specific classes and methods. |
| The package names and Maven <code>groupId</code> have been changed to <code>org.apache.logging.log4j</code> to avoid any conflicts with Log4j 1.x.</p> |

| The new features include the ability to be <em>garbage-free</em> (avoid allocating temporary objects) while logging if certain conditions are met, a new YAML Layout, the ability to merge configuration files, and documenting Log4j’s performance against other logging frameworks and in various logging configurations. |
| More details on the features and bugfixes are itemized below.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Note that subsequent to the release a minor source incompatibility was found due to the addition of new methods to the <code>Logger</code> interface. |
| If you have code that does:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-java" data-lang="java">logger.error(null, “This is the log message”, throwable);</code></pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>or similar with any log level you will get a compiler error saying the reference is ambiguous. |
| To correct this either do:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-java" data-lang="java">logger.error(“This is the log message”, throwable);</code></pre> |

| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-java" data-lang="java">logger.error((Marker) null, “This is the log message”, throwable);</code></pre> |

| <div class="paragraph"> |
| <p>Log4j 2.6 maintains binary compatibility with previous releases.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Log4j 2.6 requires a minimum of Java 7 to build and run. |
| Log4j 2.3 was the last release that supported Java 6.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Basic compatibility with Log4j 1.x is provided through the <code>log4j-1.2-api</code> component, however it does |
| not implement some of the very implementation specific classes and methods. |
| The package names and Maven <code>groupId</code> have been changed to <code>org.apache.logging.log4j</code> to avoid any conflicts with Log4j 1.x.</p> |

| <p>Apache Log4j 2.3 requires a minimum of Java 6 to build and run. |

| <h3 id="release-notes-2-0-beta9-changed">Changed</h3> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Changed the (relatively new) PatternLayout configuration attribute "suppressExceptions" to "alwaysWriteExceptions" to more correctly indicate what it does. As such, the meaning of this attribute has reversed (previous "true"s should become "false"s, and vice versa). Since this was an undocumented attribute up until now, it’s unlikely this change will affect any users.</p> |
| </li> |
| <li> |
| <p>Changed the "suppressExceptions" configuration attribute for all Appenders to "ignoreExceptions" to avoid confusion with Java 7 suppressed exceptions. Also renamed the Appender#isExceptionSuppressed() method to Appender#ignoreExceptions() to avoid the same confusion. All Appenders by default internally log and then ignore exceptions encountered while logging. Setting "ignoreExceptions" to "false" on an Appender causes it to allow exceptions to propagate to the caller. You must set "ignoreExceptions" to "false" for Appenders you are wrapping in the Failover Appender.</p> |
| </li> |
| <li> |
| <p>Cleaned up tests and cleared up documentation for the JPA appender following the resolution of EclipseLink issue #412454.</p> |
| </li> |
| <li> |
| <p>Improved site by adding quick jump-off page and menu for Javadoc links for all components.</p> |
