[ANNOUNCE] Apache Log4j 2.9.0 released
The Apache Log4j 2 team is pleased to announce the Log4j 2.9.0 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.
This release contains the first support of Java 9 as well as bugfixes and minor enhancements. The Log4j API was modified to use java.util.ServiceLoader 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.
Note that subsequent to the 2.9 release, for security reasons, SerializedLayout is deprecated and no longer used as default in the Socket and JMS appenders. SerializedLayout can still be used as before, but has to be specified explicitly. To retain old behaviour, you have to change configuration like:
<Appenders>
<Socket name="socket" host="localhost" port="9500"/>
</Appenders>
into:
<Appenders>
<Socket name="socket" host="localhost" port="9500">
<SerializedLayout/>
</Socket>
</Appenders>
We do, however, discourage the use of SerializedLayout and recommend JsonLayout as a replacement:
<Appenders>
<Socket name="socket" host="localhost" port="9500">
<JsonLayout properties="true"/>
</Socket>
</Appenders>
Note that subsequent to the 2.9 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.
The Log4j 2.9.0 API, as well as many core components, maintains binary compatibility with previous releases.

Apache Log4j 2.9.0 requires a minimum of Java 7 to build and run. Log4j 2.3 was the last release that supported Java 6.
Basic compatibility with Log4j 1.x is provided through the log4j-1.2-api component, however it does not implement some of the very implementation specific classes and methods. The package names and Maven groupId have been changed to org.apache.logging.log4j to avoid any conflicts with log4j 1.x.
For complete information on Apache Log4j 2, including instructions on how to submit bug reports, patches, or suggestions for improvement, see the Apache Apache Log4j 2 website:

Re: Announcement is ugly

When I copied from GitHub in the past, the resulting email would look just

reformatted things like that or if the mailing list software filters HTML
emails now like that.

Re: Announcement is ugly
Posted by Ralph Goers <ra...@dslextreme.com>.
What you show here looks much like what the announcement in the dev list looks like. Notice the headings for the changes are ugly even in your email.
I sent it to the dev list as one email and the announce list as a second email since I have to use different email addresses. But the content was formatted exactly the same. I suspect the announce list does extra stuff.

Example:
Apache Log4j 2.9.0 Release Notes
The Apache Log4j 2 team is pleased to announce the Log4j 2.9.0 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.
This release contains the first support of Java 9 as well as bugfixes and
minor enhancements. The Log4j API was modified to use
java.util.ServiceLoader 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.
Note that subsequent to the 2.9 release, for security reasons,
SerializedLayout is deprecated and no longer used as default in the Socket
and JMS appenders. SerializedLayout can still be used as before, but has to
be specified explicitly. To retain old behaviour, you have to change
configuration like:
<Appenders>
<Socket name="socket" host="localhost" port="9500"/>
</Appenders>
into:
<Appenders>
<Socket name="socket" host="localhost" port="9500">
<SerializedLayout/>
</Socket>
</Appenders>
We do, however, discourage the use of SerializedLayout and recommend
JsonLayout as a replacement:
<Appenders>
<Socket name="socket" host="localhost" port="9500">
<JsonLayout properties="true"/>
</Socket>
</Appenders>
Note that subsequent to the 2.9 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.
The Log4j 2.9.0 API, as well as many core components, maintains binary
compatibility with previous releases.

------------------------------
Apache Log4j 2.9.0 requires a minimum of Java 7 to build and run. Log4j 2.3
was the last release that supported Java 6.
Basic compatibility with Log4j 1.x is provided through the log4j-1.2-api
component, however it does not implement some of the very implementation
specific classes and methods. The package names and Maven groupId have been
changed to org.apache.logging.log4j to avoid any conflicts with log4j 1.x.

Announcement is ugly
Posted by Ralph Goers <ra...@dslextreme.com>.
Although it looks great at GitHub, I really dislike what copying the page there makes the actual announcement look like. It doesn’t look too bad below, except that the headings look odd, but when it goes to the announcement list it looks terrible. http://mail-archives.us.apache.org/mod_mbox/www-announce/201708.mbox/%3Ccd8b8bef-882e-fb69-6e89-d72428416ab8@apache.org%3E <http://mail-archives.us.apache.org/mod_mbox/www-announce/201708.mbox/%3Ccd8b8bef-882e-fb69-6e89-d72428416ab8@apache.org%3E>.
Any ideas?

> 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.

> This release contains the first support of Java 9 as well as bugfixes and minor enhancements. The Log4j API was modified to use java.util.ServiceLoader 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.

> Note that subsequent to the 2.9 release, for security reasons, SerializedLayout is deprecated and no longer used as default in the Socket and JMS appenders. SerializedLayout can still be used as before, but has to be specified explicitly. To retain old behaviour, you have to change configuration like:

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.

> This release contains the first support of Java 9 as well as bugfixes and
minor enhancements. The Log4j API was modified to use
java.util.ServiceLoader 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.

SerializedLayout is deprecated and no longer used as default in the Socket

be specified explicitly. To retain old behaviour, you have to change
configuration like:

> 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.

> This release contains the first support of Java 9 as well as bugfixes and minor enhancements. The Log4j API was modified to use java.util.ServiceLoader 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.

> Note that subsequent to the 2.9 release, for security reasons, SerializedLayout is deprecated and no longer used as default in the Socket and JMS appenders. SerializedLayout can still be used as before, but has to be specified explicitly. To retain old behaviour, you have to change configuration like:

> 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.

> This release contains the first support of Java 9 as well as bugfixes and minor enhancements. The Log4j API was modified to use java.util.ServiceLoader 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.

> Note that subsequent to the 2.9 release, for security reasons, SerializedLayout is deprecated and no longer used as default in the Socket and JMS appenders. SerializedLayout can still be used as before, but has to be specified explicitly. To retain old behaviour, you have to change configuration like:
