### 22th of August 2007 - Release of version 0.9.8

This version of logback synchronizes with SLF4J version 1.4.3. In particular, logback now natively supports SLF4J's MDC API introduced in SLF4J version 1.4.1. If you are using SLF4J version 1.4.1 or later please make sure upgrade to logback version 0.9.8 or later.

Fixed a number of documentation related bugs, in particular bug 90 reported by Luc Maisonobe and bug 88 reported by Sebastian Davids.

It is now possible to include configuration file fragments (in XML) as a resource. Previously, it was only possible to include a file by specifying a path to a file or a URL. This feature was requested by Michael Newcomb in bug 89.

Fixed caller data extraction problem as reported in bug 78 by Hans van der Meer.

The LoggingEvent class' constructor now correctly takes into account the argument array passed by the user. This problem was reported in bug 85 by Robert Christian.

### 29th of May 2007 - Release of version 0.9.7

This release corrects packaging bugs 75 and 76 related to the migration of logback to SLF4J version 1.4.0. There are no other changes.

### 23rd of May 2007 - Release of version 0.9.6

Logback is now aligned and compatible with SLF4J version 1.4.0, thus correcting bug 73 as reported by Andy Gerweck.

Fixed `NoClassDefFoundError` problem when running under JDK 1.4 as reported by Brian Suksomwong.

Fixed bug 63 as reported by La Canea Rosario. Calling log4j (bridge) with the trace level will no longer cause an IllegalStateException to be thrown.

Fixed bug 70 as reported by Dirk Ooms. The %throwable conversion word is now recognized as documented in the logback manual. Moreover, the manual now mentions the %nopex word which can be used to force `PatternLayout` to ignore the exception contained in the logging request.

As in most releases, the documentation has been improved.

### April 2nd, 2007 - Release of version 0.9.5

Fixed methods `isInfoEnabled`, `isWarnEnabled` and `isErrorEnabled` methods in `ch.qos.logback.classic.Logger` class which failed to work correctly. This bug was reported today by Pavel Kral on the slf4j-user list.

Contrary to previous versions of logback, the various Logger.isXYZEnabled(Marker) methods now take into account the marker information passed as parameter.

As discussed in bug 54, during automatic initialization, it makes better sense to first check for logback-test.xml file and only if that fails, to check for logback.xml. Maven2 will guarantee that the logback-test.xml file, if places undder test/resources will not be included in the artifact it produces.

### March 29th, 2007 - Release of version 0.9.4

Significant bug fixes made to `c.q.l.access.TeeFilter` and Co. Images and other binary files are now intercepted and replayed correctly. As for "x-www-form-urlencoded" post requests, their input buffer is left untouched. In a best-effort attempt, the input buffer for "x-www-form-urlencoded" post requests is later reconstructed through the request parameters. However, it may differ from the original buffer.

The logback team released today the first version of a plugin for Eclipse that allows developpers to visualize logs generated by a running application. It offers several nice features. Please check the console plugin-in guide for more details.

### March 20th, 2007 - Release of version 0.9.3

Includes in configuration files are now supported by Joran, logback's configuration framework. A file can contain an include element that has a file or url attribute pointing to a configuration file. See the chapter about configuration in the logback's online manual for more information.

Corrected bug 53 reported by Wilkins Poe. There is now a dependencies page that shows the requirements of each of logback's modules.

After a discussion on the SLF4J mailing list started by Franck Routier, a correction has been made when logging using the JCL104-over-slf4j module. Logback now correctly shows the caller location information.

As in most logback releases, the documentation has been improved.

### March 5th, 2007 - Release of version 0.9.2

The documentation is now in the docs/ directory to allow an easier access to the logback manual and website for offline viewing.

### March 5th, 2007 - Release of version 0.9.1

Logback-class now depends on SLF4J version 1.3.0 instead of 1.2.

Numerous improvements to the documentation.

Bug #46 reported by Mark Renyolds has been fixed. The `TimeUtilTest` should now run fine under any time zone.

Bug #45, also reported by Mark Reynolds, has been fixed. There should be no `ClassCastException` thrown anymore when passing an `Object` to the printing methods using the log4j-bridge module.

### January 31st, 2007 - Release of version 0.9

The `JMXConfigurator` has been improved. It now shows the context's Status objects, which lets users check the internal state of logback.
