Bumping to next development version

Fixed a bug in TimeBasedFileNamingAndTriggeringPolicyBase

Optimization in LogbackMDCAdapter.get(String)

The configuration refers to these as  suite names,  not spec names.

Formatted LogbackValve with code style settings

Fixed timing issue in JettyBasicTest

Optimization: use Collections.emptyMap() in LoggingEvent

fixes viewAsGroovy Link for configurations with styling

* modifies ignore-regex in order to ignore <span> tags correctly

The following unit tests were failing because they were expecting the
logger context to have package data enabled by default, but the default
had been changed to false in 8141f88e.

 * ExtendedThrowableProxyConverterTest.integration
 * RootCauseFirstThrowableProxyConverterTest.integration

This patch explicitly enables packaging data for the test's logger context.

Add japanese translation for logback manuals.

Add XML support to en/disable stacktrace package detail

This prevents developers from attempting to modify event's mdc map. For example by invoking

event.getMDCPropertyMap().put("k", "v");

This fixes LOGBACK-1063 by ricochet.

with the latest version the release process fails

Fixed a bug in TimeBasedFileNamingAndTriggeringPolicyBase causing the policy to always rollover according to the local system time and ignore the time zone passed in the file name pattern. LOGBACK-611 introduced the possibility to specify time zone in the file name pattern and the file names are now correctly created according to the specified time zone. However, rollover is still based on the old behaviour, e.g., if the pattern is set to /wombat/foo.{%d, UTC}, rollover will happen at midnight of the local system time, instead of midnight in UTC. If for example the log is created at 00:59+01:00 02/01/2015 (local system time), the rollover will happen at 00:00+01:00 03/01/2015 instead of 01:00+01:00 02/01/2015 (i.e., 00:00Z 02/01/2015).

Changed the default enable status of packaging info in stacktraces
to be disabled to avoid the expensive lookup unless requested.

Added an XML attribute "packageTrace" to <configuration> in order to
allow enabling or disabling the packaging info in stacktraces. When
the attribute is omitted, the default setting is assumed (disabled).

To enable package detail in logback.xml:

  <configuration packageTrace="true">
    ...
  </configuration>
