values as well.</para></listitem>

<listitem><para><link linkend="TYPE_LOGICALEXPRESSION"> logicalexpression

<para> <itemizedlist mark='opencircle'>

<listitem><para>This release features some bigger cleanup changes.
Some of them do break compatibility with older version of TaskJuggler.
While we try very hard to avoid such situations, we do prefer to have
a consistent and logical language. Since the TaskJuggler user base is
still comparatively small, we decided to break compatibility now
rather than later. The changes are fairly minor, so they won't affect
many users.  Please see further down for more details.</para></listitem>

project information.</para></listitem>

</para></listitem>

<listitem><para>The optional attribute <link

<listitem><para>Include statements within tasks are no longer
supported. They lead to ambiguous interpretation of
certain attributes.</para></listitem>

<listitem><para>The optional attribute <link

linkend="PROPERTY_export">export</link>. This allows to export sub tasks of a

specify whether you like to start you week on Sunday or
Monday.</para></listitem>

<listitem><para>Support for a <computeroutput>flags</computeroutput>

<listitem><para>Sub tasks do now inherit the dependencies of their
container tasks. Specifying dependencies after sub tasks is now
illegal since they would be only used for checking, but not for
scheduling.</para></listitem>

<listitem><para>The logic checker for task attributes has been
completely rewritten. Since it probably catches some more errors, you
might have to fix your project now. Such cases would have resulted in
wrong results anyhow. Lots of test cases have been added to the test

attribute.</para></listitem>

<listitem><para>The HTML reports feature now 3 kind of index numbers.
The sequence number reflects the order of declaration in the project
files. The index is a logical order based on the hierarchy and other

sets.</para></listitem>

Due to a bug in the scheduling algorithm a heavy mixture of ALAP and
