It is totally backward compatible with SLF4J version - 1.5.8. However, the slf4j-ext module ships with a new package called - <code>org.slf4j.cal10n</code> which adds <a - href="localization.html">localized/internationalized logging</a> - support as a thin layer built upon the <a - href="http://cal10n.qos.ch">CAL10N API</a>.</p> - - <p><a href="http://www.slf4j.org/android/">SLF4J-adroid</a>, - maintained by <a - href="http://dbis.cs.unibas.ch/team/thorsten-moller/dbis_staff_view">Thorsten - Möller</a>, was added as a daugther project of SLF4J. - </p> - - <p>Added missing "Export-Package" declaration for cal10n in the OSGi - manifest file for sfl4j-ext. This was requested in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=156">bug 156</a> by - Pete Muir.</p> - - <p>In log4j-over-slf4j, added missing log(...) methods as requested - by Zoltan Szel in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=139">bug report - 139</a>.</p> - - <p>In log4j-over-slf4j, added missing <code>LogManager</code> class - as requested by Rick Beton in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=150">bug report - 150</a>.</p> - - <p>In the slf4j-ext module, added - <code>getCopyOfChildTimeInstruments</code> and - <code>getCopyOfGlobalStopWatch</code> methods to the - <code>Profiler</code> class. This enables developers to build their - own output formatters for a given Profiler. This feature was - requested by David Lindelöf in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=141">bug 141</a>. - </p> - - <p>Fixed a <code>NullPointerEception</code> occuring in unspecified - conditions as described in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=146">bug report - 146</a> by Dapeng Ni.</p> - - <p>Added missing OSGi manifest to the <em>log4j-over-slf4j</em> - module as requested by Wade Poziombka in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=117">bug 117</a>. - </p> - - <p>OSGi manifests produced by SLF4J now replace the '-' character by - '.' in compliance with the OSGi specification.

It is totally backward - compatible with SLF4J version 1.5.7.</p> - - <p>The Maven pom file for the <code>log4j-over-slf4j</code> module - contained a compile time dependency on the <code>slf4j-jdk14</code> - module. The dependency should have been declared in the test - scope. This problem was reported by Jean-Luc Geering on the slf4j - user list. - </p> - - <h3>June 10th, 2009 - Release of SLF4J 1.5.7</h3> - - <p>SLF4J version 1.5.7 consist of bug fixes and minor - enhancements. It is totally backward compatible with SLF4J version - 1.5.6.</p> - - <p>In SLF4J versions 1.5.5 and 1.5.6, the <code>LoggerFactory</code> - class which is at the core of SLF4J, if a version compatibility - issue was detected, accidentally invoked a method which was - introduced in JDK 1.5. Thus, instead of issuing a clear warning - message, SLF4J would throw a - <code>NoClassDefFoundError</code>. Consequently, SLF4J would not run - with JDK 1.4 and earlier but only if a version incompatibility issue - was present. For example, if you were mixing - <em>slf4j-api-1.5.6.jar</em> with <em>slf4j-simple-1.4.2.jar</em>, - which are mutually incompatible. Please note that this bug affects - only SLF4J versions 1.5.5 and 1.5.6 <em>and</em> only in the - presence of incompatible versions of slf4j-api and its binding. - </p> - - <p>SLF4J will now emit a warning if more than one binding is present - on the class path. This enhancement was proposed in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=132">bug 132</a> - contributed by by Robert Elliot. - </p> - - <p>The Log interface implementations in the jcl-over-slf4j module - will now correctly cope with serialization. This fixes <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=79">bug 79</a> - reported by Mathias Bogaert. Many thanks to Eric Vargo for precisely - identifying the problem and supplying the corresponding patch.</p> - - <p>The log4j-over-slf4j module will now correctly - interact with logging frameworks supporting location information - such as java.util.logging and logback. This fixes <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=131">bug 131</a> - reported by Marc Zampetti. - </p> - - <p><code>SLF4JBridgeHandler</code> will no longer ignore log records - with an empty message. This fixes <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=108">bug 108</a> - reported by Pepijn Van Eeckhoudt and independently by Dan Lewis. - </p> - - <p>In case the <code>toString()</code> method of a parameter throws - an exception, <code>MessageFormatter</code> will now print an error - message, instead of letting the exception bubble higher up as - previously. This fixes <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=112">bug 112</a> - submitted by Joern Huxhorn. - </p> - - <hr noshade="noshade" size="1"/> - - <h3>November 21st, 2008 - Release of SLF4J 1.5.6</h3> - - <p>SLF4J version 1.5.6 consists of bug fixes. Users are encouraged - to upgrade to SLF4J version 1.5.6. The upgrade should pose no - problems. Nevertheless, you might still want to refer to the SLF4J - <a href="compatibility.html">compatibility report</a>. - </p> - - <p>Fixed long standing <a - href="http://jira.qos.ch/browse/LBCLASSIC-87">LBCLASSIC-87</a> and - its younger sibling <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=113">bug - 113</a>. With each call to getLogger() method, - <code>LoggerContext</code> will now retrieve the ILoggerFactory - afresh from <code>StaticLoggerBinder</code>. This change enables - context selectors of native implementations, e.g logback, to work - correctly. - </p> - - <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=114">bug - 114</a> reported by Jason Arndt. Corrected the way - <code>XLogger</code> (in slf4j-ext) passes its fully qualified class - name so that the underlying logging system can correctly compute - location information. - </p> - - - <p>The <code>install()</code> method of - <code>SLF4JBridgeHandler</code> will no longer reset the entire - j.u.l. environment but solely add a <code>SLF4JBridgeHandler</code> - instance to jul's root logger. By the same token, the - <code>uninstall()</code> method will remove previously added - <code>SLF4JBridgeHandler</code> instances without making any other - modifications to the j.u.l. configuration. - </p> - - <p>Added <code>MDCStrLookup</code> to slf4j-ext. This class can be - used with Apache Commons Lang's <code>StrSubstitutor</code> class to - inject values in the SLF4J MDC into strings. Information on - StrSubstitutor can be found at <a - href="http://commons.apache.org/lang/api-release/org/apache/commons/lang/text/StrSubstitutor.html">StrSubstitutor - javadoc</a>. - </p> - - <hr noshade="noshade" size="1"/> - - <h3>October 17th, 2008 - Release of SLF4J 1.5.5</h3> - - <p>The version check mechanism introduced in SLF4J 1.5.4 was - inconsistent with the large size of SLF4J's installed user base. We - cannot expect external SLF4J implementations to align their release - schedule with that of SLF4J. Consequently, this SLF4J version, - namely 1.5.5, retains versions checks but as an elective - process. For further details see the <a - href="faq.html#version_checks">relevant entry</a> in the FAQ. - </p> - - <p>You are highly encouraged to upgrade to SLF4J version 1.5.5. The - upgrade should pose no problems. Nevertheless, you might still want - to refer to the SLF4J <a href="compatibility.html">compatibility - report</a>. - </p> - - <h3>October 16th, 2008 - Release of SLF4J 1.5.4</h3> - - <p>This version corrects critical bugs. - </p> - - <p>Fixed <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=106">critical bug - 106</a>. In previous versions of SLF4J, if during the initial - binding phase, the underlying logging system's default configuration - created or invoked loggers, a <code>NullPointerException</code> - would be thrown. Refer to the <a - href="codes.html#substituteLogger">in error codes</a> document for a - fuller explanation.</p> - - <p>At initialization time, LoggerFactory will now check that the - version of the slf4j-binding matches that of slf4j-api. If there is - a mismatch a warning will be issued on the console. This should help - users identify SLF4J related problems more quickly.</p> - - <p>Improvements in documentation as well as fix for <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=102">packaging - problems</a> related to <em>slf4j-ext</em> module. - </p> - - <p>SLF4JBridgeHandler (part of jul-to-slf4j) now accounts for - loggers with resourceBundle as well parameters. This feature - requested by Darryl Smith in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=98">bug 98</a> and - by Jarek Gawor in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=103">bug - 103</a>.</p> - - <p>We now say that markers contain <em>references</em> to other - markers. We no longer talk about child markers. The javadocs of the - <code>Marker</code> interface have been updated to reflect this - change. Moreover, the <code>hasChildren()</code> method in the - Marker interface has been deprecated and a new method called - <code>hasReferences()</code> was added. - </p> - - <hr noshade="noshade" size="1"/> - - <h3>September 12th, 2008 - Release of SLF4J 1.5.3</h3> - - <p>See also the <a href="compatibility.html#1_5_3">compatibility - report for this version</a>. - </p> - - <p>Added a new module called slf4j-ext for slf4j-extensions. See <a - href="extensions.html">its documentation</a> for further - details.</p> - - <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=71">bug - 71</a> which was re-opened by Manfred Geiler. SLF4J loggers now - survive serialization. By survive serialization, we mean - that the deserialized logger instance are fully functional. </p> - - <p>The fix for <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=68">bug 68</a> as - implemented in version 1.5.1 was incomplete. Michael Furman supplied - a more complete fix which was incorporated in this release.</p> - - <p>When slf4j bridges, e.g. jcl-over-slf4j or log4j-over-slf4j, were - used in conjunction with JUL as the underlying logging system, - JDK14LoggerAdapter created a LogRecord even for disabled log - statements. This performance issue was reported in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=90">bug 90</a> by - Matthew Mastracci. - </p> - - <p>Added support for array values, including multi-dimensional - arrays, as parameters. For example,</p> - <p class="source">log.debug("{} {}", "A", new int[] {1, 2}});</p> - <p>will print as "A [1, 2]" instead of "A [I@6ca1c" as - previously. This enhancement was proposed by "lizongbo". - </p> - - <p>Parameter substitution code has been simplified. SLF4J now only - cares about the "{}" formatting anchor, that is the '{' character - immediately followed by '}'. Previously, the '{' had meaning on its - own. As a result of this change, users no longer need to escape the - '{' unless it is immediately followed by '}'. Existing messages - which escaped standalone '{' character will be printed with a - preceding backslash. However, no data loss in the printed messages - will occur. - </p> - - <p>Added missing <code>getInstance</code> methods to the - <code>Category</code> class in the log4j-over-slf4j module, fixing - <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=95">bug 95</a> - reported by Michael Rumpf.</p> - - <hr noshade="noshade" size="1"/> - - <h3>June 8th, 2008 - Release of SLF4J 1.5.2</h3> - - <p>Improvements to SLF4J documentation as well as fix of <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=88">packaging - problems</a> related to <em>jul-to-slf4j.jar</em> and - <em>jcl104-over-slf4j.jar</em>. - </p> - - <h3>June 5th, 2008 - Release of SLF4J 1.5.1</h3> - - <p>See also the <a href="compatibility.html#1_5_1">compatibility - report for this version</a>.</p> - - <p>In order to support JCL version 1.1.1, the - <em>jcl<b>104</b>-over-slf4j</em> module was renamed as - <em>jcl-over-slf4j</em>. SLF4J will no longer ship with - <em>jcl104-over-slf4j.jar</em> but with <em>jcl-over-slf4j.jar</em>. - The related work responds to enhancement request discussed in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=85">bug 85</a> as - reported by Niklas Gustavsson. - </p> - - <p>The <em>slf4j-jcl</em> binding now depends on commons-logging - version 1.1.1 instead of the older 1.0.4</p> - - - <p>Added a java.util.logging to SLF4J bridge as requested in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=38">bug 38</a> by - Christian Stein, David Smiley, Johan Ferner, Joern Huxhorn and - others. - </p> - - <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=68">bug - 68</a> reported by Su Chuan and David Rauschenbach. SLF4J requires - log4j 1.2.12 or later. However, if an older version of log4j is - present (lacking the TRACE level), in order to avoid - NoSuchMethodError exceptions, the SLF4J's - <code>Log4jLoggerAdapter</code> will map the TRACE level as DEBUG. - </p> - - - <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=78">bug - 78</a> reported by Venu Thachappilly. If the argument array passed - to a Logger printing method (debug, info, etc.) was null, a - <code>NullPointerException</code> was thrown. With the correction, - the messagePattern is returned as is, without parameter - substitution. - </p> - - - <p>Added the <code>getCopyOfContextMap</code> and - <code>setContextMap</code> methods to the <code>MDCAdapter</code> - and <code>org.sf4j.MDC</code> classes. This was requested in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=84">bug 84</a> by - Anton Tagunov. - </p> - - <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=74">bug - 74</a>, an endless recursion problem in Marker.contains method, - reported by Michael Newcomb. Also added he - <code>getDetachedMarker</code> method to <code>IMarkerFactor</code> - and <code>MarkerFactory</code> classes which was indirectly - requested in bug 74. - </p> - - <p>Added the methods <code>getLevel()</code> and - <code>getEffectiveLevel()</code> to the <code>Category</code> class - in log4j-over-slf4j. This addition was requested in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=74">bug 74</a> by - Michael Newcomb. - </p> - - <p>The <a href="migrator.html">SLF4J Migrator</a> - tool has been improved to support migration from JUL to SLF4J. - </p> - - <p>In <code>MarkerIgnoringBase</code> class, corrected mapping of - trace methods with markers to their equivalents without marker - data. Previously, the mapping was trace to debug. The incorrect - mapping affected only calls to the trace method with - markers. Interestingly enough, this bug was picked up by new unit - tests and has not been reported as a bug by our users. - </p> - - - <h3>February 26th, 2008 - Release of SLF4J 1.5.0</h3> - - - <p>A tool called <a href="migrator.html">SLF4J Migrator</a> now - ships with SLF4J. It can help you migrate your project using JCL or - log4j to use SLF4J instead. - </p> - - <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=61">bug - 61</a> reported by Christopher Sahnwaldt. It is now possible to - place a backslash in front of a formatting anchor, by escaping the - backslash. For example, the call to - <code>MessageFormatter.format("C:\\\\{}", "foo")</code> will now - correctly return "C:\\foo". The backslash character needs to be - escaped in Java, which leads to four backslashes. - </p> - - - <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=63">bug - 63</a> reported by Maarten Bosteels. SLF4J now supports MDC for - <code>java.util.logging</code> package. - </p> - - <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=64">bug - 64</a> reported by Michal Bernhard. The log4j binding will now alert - the user if she uses SLF4J with a version of log4j earlier than 1.2.12. - </p> - - <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=65">bug - 65</a> reported by Ben Gidley. Superfluous - <version>${parent.version}</version> lines have been - removed from pom.xml files. These lines reportedly confuse certain - Maven repositories. - </p> - - <p>In the <code>org.apache.log4j.Category</code> class, as - implemented in the log4j-over-slf4j module, calls to the printing - trace() are now correctly mapped to SLF4J's trace() printing method - (instead of debug()). Superfluous printing methods with the - signature <code>xxxx(Object, Object)</code> and <code>xxxx(String, - Object, Object)</code> have been removed. - </p> - - <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=67">bug - 67</a> reported by Chris Custine. The manifest file for - jcl104-over-slf4j now correctly declares version 1.0.4 for the - exported JCL packages. - </p> - - - <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=69">bug - 69</a> reported by Joern Huxhorn, who graciously supplied the fix as - well as a test case. The <code>add</code> method in - <code>BasicMarker</code> class now correctly prevents multiple - addition of the same child. Moreover, the <code>remove</code> method - now correctly removes the specified child marker. - </p> - - <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=41">bug - 41</a> reported by Sebastian Davids.

This bug - was <a - href="http://www.slf4j.org/pipermail/user/2007-April/000323.html">reported</a> - and precisely described by Andrew Cooke. - </p> - - - <hr noshade="noshade" size="1"/> - - <h3>February 25th, 2007 - Release of SLF4J 1.3.0</h3> - - <p>This release consists of rearrangement of classes among - projects. More specifically, the - <code>org.slf4j.LoggerFactory</code> class is now packaged within - the <em>slf4j-api.jar</em> file instead of the various slf4j - bindings. <b>It follows that client code needs to depend on only - slf4j-api in order to compile, while the various slf4j bindings are - only needed as runtime dependencies.</b> See also the <a - href="faq.html#maven2">Maven2-related FAQ entry</a>. Given the - practical significance of this change, we highly recommend that - library-authors upgrade to version 1.3 at their earliest - convenience. - </p> - - <p><a href="http://bugzilla.slf4j.org/show_bug.cgi?id=23">Bug number - 23</a> has been fixed, at the cost of minor and backward compatible - changes. In other words, jcl104-over-slf4j now preserves caller - location information. - </p> - - <p>It is now possible to obtain the root logger of the underlying - logging implementation by requesting a logger named - "ROOT". This feature was requested by Sebastien Davids - in <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=35">bug - report 35</a>. </p> - - <p>For an exact list of changes please refer to the <a - href="changes/changes-1.3.txt">1.3.0 compatibility report</a> file - as generated by clirr.</p> - - - <hr noshade="noshade" size="1"/> - - <h3>January 24th, 2007 - Release of SLF4J 1.2</h3> - <p>This release includes several modifications to make SLF4J - an <a href="http://www.osgi.org/">OSGi</a>-friendly framework. - The modules' MANIFEST.MF files now include - OSGi metadata. Regarding these improvements, and OSGi in general, the - SLF4J project is happy to welcome John E.

More importantly, the log4j-over-slf4j module has been - moved to the logback project, under the name <a - href="http://logback.qos.ch/bridge.html">log4j-bridge</a>. - </p> - - <p>Added the file "org.apache.commons.logging.LogFactory" under - META-INF/services directory which went missing in the 1.1.0 series - of SLF4J. This fixes a compatibility problem with Apache Axis which - uses its own discovery mechanism, namely, commons-discovery version - 0.2. The problem was reported in bug <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=33">report 33</a> - by David Varnes. - </p> - - <p>The file jcl104-over-slf4j.jar had various entries missing in its - MANIFEST.MF file, as reported by Boris Unkel in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=30">bug number - 30</a>. - </p> - - <hr noshade="noshade" size="1"/> - - <h3>November 16th, 2006 - Release of SLF4J 1.1.0-RC1</h3> - - <p>This release consists of packaging related bug fix in addition to - minor documentation changes. - </p> - - <p>Contrary to RC0, RC1 no longer uses SNAPSHOT versions for the - slf4j-parent pom. The solution to <a - href="http://ceki.blogspot.com/2006/11/solution-to-maven2-version-number.html">Maven - version problem</a> does not work for public projects such as SLF4J - because SNAPHOTs are not allowed on ibiblio. - </p> - - - <hr noshade="noshade" size="1"/> - - <h3>November 4th, 2006 - Release of SLF4J 1.1.0-RC0</h3> - - <p>This release consists of bug fixes.

SLF4J now explicitly declares a dependency on JDK 1.4 in its - pom.xml file. - </p> - - <p>Fixed an incorrect reference to the logback project in slf4j-api - pom file. This bug was reported by Boris Unkel in <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=29">bug number - 29</a>. - </p> - - <p>Fixed a synchronization problem in factories of almost all SLF4J - bindings. This bug was reported independently by Howard M. Lewis Ship - and Boris Unkel in bug reports <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=26">26</a> and - respectively <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=26">27</a>. - </p> - - <hr noshade="noshade" size="1"/> - - <h3>September 7th, 2006 - Release of SLF4J 1.1.0-beta0</h3> - - <p>Release 1.1.0-beta0 is a relatively important release with a - refactoring of the way class files are organized in jar files. In - previous releases, each binding was self-contained in a single jar - file. In this release, each and every binding depends on - <em>slf4j-api.jar</em> which contains the bulk of the classes - required to use SLF4J, except for one or two adapter classes. Only - the adapter classes are now shipped with each specific binding jar - as appropriate for the underlying logging system.. - </p> - - <p>This release is built using Maven instead of Ant. As for the java - code, it has not been changed.</p> - - <hr noshade="noshade" size="1"/> - - <h3>June 8th, 2006 - Release of SLF4J 1.0.2</h3> - - <p>Release 1.0.2 is a maintenance release containing bug fixes - only.</p> - - <ul> - - <li>Fixed <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=22">bug number - 22</a> reported by Bjorn Danielsson.

This change - should not adversely affect end-users. However, SLF4J bindings need - to be updated. This has been done for all the bindings shipped with - SLF4J distribution as well as NLOG4J. As for x4juli, the update is - planned for its next release. - </p> - - <p>The merge between the <code>MarkingLogger</code> and - <code>Logger</code> interfaces has been motivated by the need to - allow end-users to easily switch between logging systems that - support markers and those that do not. - </p> - - <p>Added a default instance to SimpleLoggerFactory to serve as a - last resort fallback mechanism. This instance is designed to be used - by a very specific group of users, namely for those developing - logging systems (e.g. log4j or LOGBack). It is not intended for - end-users of the SLF4J API. - </p> - - <hr noshade="noshade" size="1"/> - - <h3>January 9th, 2006 - Release of SLF4J 1.0-RC5 and NLOG4J - 1.2.21</h3> - - <p>A maintenance release correcting bugs <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=11">#11</a> and <a - href="http://bugzilla.slf4j.org/show_bug.cgi?id=12">#12</a> and in - general improved resilience to null input parameters across - implementations.

Many - thanks to Christian Beil for accurately reporting bug #4. - </p> - - <p>There has been also an effort to minimize the file sizes of the - various jar files produced by SLF4J, resulting in jar files - approximately 40% smaller than in version 1.0beta9. - </p> - - <p>Given that the SLF4J API is now deemed stable, this release is - marked as RC1, that is release candidate number 1. - </p> - - - <hr noshade="noshade" size="1"/> - - <h3>October 19th, 2005 - Release of SLF4J 1.0-beta9</h3> - - <p>The SLF4J distribution now includes two distinct bindings - <em>slf4j-log4j12.jar</em> and <em>slf4j-log4j13.jar</em> in order - to differentiate between log4j version 1.2 and version 1.3. This - distinction is absolutely necessary because log4j 1.2 and 1.3 are - not run-time compatible, although they are mostly compile-time - compatible. - </p> - - <hr noshade="noshade" size="1"/> - - <h3>October 19th, 2005 - Release of SLF4J 1.0-beta8 and NLOG4J 1.2.18</h3> - - - <p>Added a new SLF4J binding, <em>slf4j-log4j.jar</em>, intended to - be used in conjunction with vanilla <em>log4j.jar</em>, as - distributed by the <a href="http://logging.apache.org">Apache - Logging Services</a> project. The slf4j-log4j binding is quite - similar in structure to the JDK 1.4 binding that existed - previously. - </p> - - <p>The slf4j-log4j binding addresses compatibility problems which - arose when copies of both <em>log4j.jar</em> and <em>nlog4j.jar</em> - lay on the class path, in particular when it was undesirable or - impossible to remove the preexisting <em>log4j.jar</em> file. - </p> - - <p>Methods in the <code>org.slf4j.Logger</code> interface related to - markers were moved to a separate super interface called <a - href="api/org/slf4j/MarkingLogger.html"> - <code>org.slf4j.MarkingLogger</code></a>.

It is totally backward compatible with SLF4J version + 1.5.6.</p> + + <p>In SLF4J versions 1.5.5 and 1.5.6, the <code>LoggerFactory</code> + class which is at the core of SLF4J, if a version compatibility + issue was detected, accidentally invoked a method which was + introduced in JDK 1.5. Thus, instead of issuing a clear warning + message, SLF4J would throw a + <code>NoClassDefFoundError</code>. Consequently, SLF4J would not run + with JDK 1.4 and earlier but only if a version incompatibility issue + was present. For example, if you were mixing + <em>slf4j-api-1.5.6.jar</em> with <em>slf4j-simple-1.4.2.jar</em>, + which are mutually incompatible. Please note that this bug affects + only SLF4J versions 1.5.5 and 1.5.6 <em>and</em> only in the + presence of incompatible versions of slf4j-api and its binding. + </p> + + <p>SLF4J will now emit a warning if more than one binding is present + on the class path. This enhancement was proposed in <a + href="http://bugzilla.slf4j.org/show_bug.cgi?id=132">bug 132</a> + contributed by by Robert Elliot. + </p> + + <p>The Log interface implementations in the jcl-over-slf4j module + will now correctly cope with serialization.

Many thanks to Eric Vargo for precisely + identifying the problem and supplying the corresponding patch.</p> + + <p>The log4j-over-slf4j module will now correctly + interact with logging frameworks supporting location information + such as java.util.logging and logback. This fixes <a + href="http://bugzilla.slf4j.org/show_bug.cgi?id=131">bug 131</a> + reported by Marc Zampetti. + </p> + + <p><code>SLF4JBridgeHandler</code> will no longer ignore log records + with an empty message.

This change + should not adversely affect end-users. However, SLF4J bindings need + to be updated. This has been done for all the bindings shipped with + SLF4J distribution as well as NLOG4J. As for x4juli, the update is + planned for its next release. + </p> + + <p>The merge between the <code>MarkingLogger</code> and + <code>Logger</code> interfaces has been motivated by the need to + allow end-users to easily switch between logging systems that + support markers and those that do not. + </p> + + <p>Added a default instance to SimpleLoggerFactory to serve as a + last resort fallback mechanism. This instance is designed to be used + by a very specific group of users, namely for those developing + logging systems (e.g. log4j or LOGBack). It is not intended for + end-users of the SLF4J API. + </p> + + <hr noshade="noshade" size="1"/> + + <h3>January 9th, 2006 - Release of SLF4J 1.0-RC5 and NLOG4J + 1.2.21</h3> + + <p>A maintenance release correcting bugs <a + href="http://bugzilla.slf4j.org/show_bug.cgi?id=11">#11</a> and <a + href="http://bugzilla.slf4j.org/show_bug.cgi?id=12">#12</a> and in + general improved resilience to null input parameters across + implementations.

The slf4j-log4j binding is quite + similar in structure to the JDK 1.4 binding that existed + previously. + </p> + + <p>The slf4j-log4j binding addresses compatibility problems which + arose when copies of both <em>log4j.jar</em> and <em>nlog4j.jar</em> + lay on the class path, in particular when it was undesirable or + impossible to remove the preexisting <em>log4j.jar</em> file. + </p> + + <p>Methods in the <code>org.slf4j.Logger</code> interface related to + markers were moved to a separate super interface called <a + href="api/org/slf4j/MarkingLogger.html"> + <code>org.slf4j.MarkingLogger</code></a>.
