| <div class="paragraph"> |
| <p>This release primarily contains bug fixes 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. |
| 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>The Log4j 2.19.0 API, as well as many core components, maintains binary compatibility with previous releases.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Apache Log4j 2.19.0 requires a minimum of Java 8 to build and run. |
| Log4j 2.12.4 is the last release to support Java 7. |
| Log4j 2.3.2 is the last release to support Java 6. |
| Java 6 and Java 7 are no longer supported by the Log4j team.</p> |
| </div> |
| <div class="paragraph"> |
| <p>For complete information on Apache Log4j 2, including instructions on how to submit bug reports, patches, or suggestions for improvement, see <a href="http://logging.apache.org/log4j/2.x/">the Apache Log4j 2 website</a>.</p> |
