The Apache Log4j 2 team is pleased to announce the Log4j 2.13.3 release! Apache Log4j is a well known framework for logging application behavior. = Log4j 2 is an upgrade to Log4j that provides significant improvements = over its predecessor, Log4j 1.x, and provides many other modern features = such as support for Markers, lambda expressions for lazy logging, = property substitution using Lookups, multiple patterns on a = PatternLayout and asynchronous Loggers. Another notable Log4j 2 feature = is the ability to be "garbage-free" (avoid allocating temporary objects) = while logging. In addition, Log4j 2 will not lose events while = reconfiguring. The artifacts may be downloaded from = https://logging.apache.org/log4j/2.x/download.html. This release contains a fix for bug LOG4J2-2838. Due to a break in compatibility in the SLF4J binding, Log4j now ships = with two versions of the SLF4J to Log4j adapters. log4j-slf4j-impl = should be used with SLF4J 1.7.x and earlier and log4j-slf4j18-impl = should be used with SLF4J 1.8.x and later. Note that the default XML, JSON and YAML formats changed in the 2.11.0 = release: they no longer have the "timeMillis" attribute and instead have = an "Instant" element with "epochSecond" and "nanoOfSecond" attributes. = If the previous behavior is desired the "includeTimeMillis" attribute = may be set to true on each of the respective Layouts. The Log4j 2.13.3 API, as well as many core components, maintains binary = compatibility with previous releases. GA Release 2.13.3 Changes in this version include: Fixed Bugs =E2=80=A2 LOG4J2-2838: Fix NullPointerException in = ThreadContextDataInjector. Apache Log4j 2.13.3 requires a minimum of Java 8 to build and run. Log4j = 2.3 was the last release that supported Java 6 and Log4j 2.12.1 is the = last release to support Java 7.
