* Project.getBuildListeners now returns a clone of the listener
  list. Changes to the returned list will not affect the listeners
  currently attached to the Project. It also means that it is safe to
  iterate over the returned list if listeners are added or removed
  during the traversal.

* <pvcs> default filenameformat has been different from Ant 1.4.1.
  Now it is different from 1.5beta1 and 1.5beta2.

* Some messages that are printed during startup will not be
  written to the logfile specified via -logfile as they might destroy
  the format of the file for special BuildLoggers (like XmlLogger).

Fixed bugs:
-----------

* <available> could fail to find files or directories that happen to
  start with the name of the project's basedir but are not children of
  the basedir.

* Nested <property>'s inside <ant> can now be overriden by subsequent
  <ant> and <antcall> tasks.

* <xslt>'s outputtype attribute wouldn't do anything.

* <linecontains> filterreader could swallow lines.

* <sequential> used to configure the tasks (set their attributes)
  before the first task has been executed.  This means that properties
  that have been set by nested task seemed to be unset for the other
  tasks in the same <sequential> element.

* <javac>'s sourcepath setting has been ignored by some compiler
  implementations.

* <javadoc>'s packagelist attribute didn't work.

* the plain mailer would always use port 25 in <mail>.

* Ant's default logger could swallow empty lines.

* ejbjar's iPlanet nested element now can process multiple descriptors.

* IPlanetEjbc was looking in the wrong place for four iiop files.

* <javac> would pass the -source switch to JDK 1.3's javac, even
  though it doesn't support it.

Other changes:
--------------

* <checksum> now uses a buffer (of configurable size).

* The "Trying to override task definition" warning has been degraded
  to verbose level if the two task definitions only differ in the class
  loader instance that has loaded the definition.

* Add a jvmargs to the ejbjar's weblogic element to allow additional
  arguments to be provided to the VM runnign ejbc. Document the
  jvmdebuglevel attribute which can be used to avoid warnings about
  interface classess being found on the classpath. Document the new
  <sysproperty> element which allows JVM properties to be defined.
  Added an outputdir attribute to allow the destination to be a
  directory into which the exploded jar is written.

* ejbjar now supports Borland Enterprise Server 5 and Jonas 2.5

Changes from Ant 1.5beta1 to Ant 1.5beta2
=========================================

Changes that could break older environments:
--------------------------------------------

* Properties will now be expanded in mail message bodies.  This means
that one $ sign will be stripped if your mail message contains the text
$$.

* org.apache.tools.ant.taskdefs.Expand no longer extends MatchingTask.

* Available#setFile now again uses a File argument as it did in 1.4,
this may break environments that have been adapted to the String
argument version present in 1.5beta1.

Fixed bugs:
-----------
* When <move> attempts a rename, it deletes the destination file, if it
  exists, before renaming the source file.  However, <move> was not
  checking if the destination file was actually a directory before
  trying to delete it.

* Make CVS Tasks to work under Cygwin.

* Fix LineContains to handle huge files elegantly without causing
Stack Overflows.

* if you ask for the "classic" compiler on Java1.4, you get upgraded to
"modern" because there is no classic compiler any more.

* the <http> condition was viewing 404 'not found' exceptions as success. Now
it defaults to viewing any response >=400 as an error, and has an errorsBeginAt
attribute you can use if you want a higher or lower value.

* <get> throws a build exception on an http authorization error, unless you
have set ignoreerrors to true.

* <wsdltodotnet> was spelt in Wintel case: <WsdlToDotnet>. It is now lower
case, though the old spelling is retained for anyone who used it.

* Merging of Manifests in jar now works as documented.

* paths that have been separated by colons would be incorrectly parsed
on NetWare.

* runant.pl now supports NetWare.

* <tempfile> and <setproxy> tasks were in beta1, but not defined by
default; They now are. <tempfile> fills a property with the name of a
temporary file; <setproxy> lets you set the JVM's http, ftp and socks proxy
settings.

* <available classname="foo" ignoresystemclasses="true"> failed for
JDK 1.1 and 1.2, even if the class could be found on the
user-specified classpath.

* <property environment=... /> now works on z/OS.

* forked <javac> failed for the wrong reason on JDK 1.1 - Ant would
use a temporary file to hold the names of the files to compile under
some conditons, but 1.1 doesn't support this feature.  Ant will no
longer try this, but you may run into problems with the length of the
command line now.

* the refid attribute for <property>s nested into <ant> or <param>s
nested into <antcall> didn't work.

* <replaceregexp> didn't work for nested <fileset>s.

* <javadoc> dropped sourcepath entries if no "interesting" .java
source files  could be found below them.  This has been backwards
incompatible and caused problems with custom doclets like xdoclet.

* Using the doclet, docletpath or docletpathref attributes of
<javadoc> may have caused NullPointerExceptions.

* nested <filesets> of <javadoc> would include too much.

* <dependset> will no longer choke on <targetfileset>s that point to
non-existing directories.

* <patch> didn't work at all.

* <replace> and <replaceregexp> now fail if the file they are working
on is locked.

* <javadoc> would pick up the wrong executable in the combination JDK
1.2  and AIX.

Other changes:
--------------

* z/OS now gets detected by the os condition.

* <fileset> and <dirset> now have an optional followsymlink attribute
that can prevent Ant from following symbolic links on some platforms.

* BeanShell is now supported in the <script> task.

* <ejbjar> under Weblogic attempts to use the ejbc20 compiler for 2.0 beans
  based on the deployment descriptor's DTD reference. Under weblogic 7.00 Beta
  this ejbc class has been deprecated. To avoid the deprecation warning use
  ejbcclass="weblogic.ejbc".

* <ejbjar> will add a manifest to the generated jar based on the naming
  convention in use. This overrides the manifest specified in the
  <ejbjar> attribute


Changes from Ant 1.4.1 to 1.5beta1
==================================

Changes that could break older environments:
--------------------------------------------

* Important: Single $ signs are no longer silently stripped!

* The filesetmanifest attribute added to <jar> after the 1.4.1
  release has been removed for now.  This change may affect only
  the 1.5Beta/1.6Alpha users.  An attempt will be made to add this
  feature back into Ant 1.6.

Fixed bugs:
-----------

* <zip> and friends would always update existing archive if you set
  the update attribute to true.

* To support backward compatibility with older versions, <pathconvert>
  will once again set the property, even if the result is the empty
  string, unless the new 'setonempty' attribute is set to false|no|off
  (default is "true").

* The manifest task would crash XmlLogger

Other changes:
--------------

* added **/.svn and **/.svn/** to the default excludes
