The Apache Ant team currently maintains two lines of development. The 1.9.x releases require Java5 at runtime and 1.10.x requires Java8 at runtime. Both lines are based off of Ant 1.9.7 and the 1.9.x releases are mostly bug fix releases while additional new features are developed for 1.10.x.
The latest releases are 1.9.14 and 1.10.5 and 1.10.5 contains a superset of 1.9.14 - with the exception of a few tasks and features that no longer work with Java8 anyway (like the apt task).
The full release notes of the latest releases are below.
Changes from Ant 1.9.13 TO Ant 1.9.14 ===================================== Changes that could break older environments: ------------------------------------------- * ClearCase#runS has been augmented by a two arg-version and the one-arg version will no longer be called. This may affect subclasses that have overridden runS. Fixed bugs: ----------- * fetch.xml must retrieve runtime rather than compile dependencies for mail task. Bugzilla Report 62621 * augment task now throws a BuildException (as noted in its manual) instead of a IllegalStateException in the absence of the "id" attribute. Bugzilla Report 62655 * org.apache.tools.zip.ZipOutputStream would sometimes potentially use an incorrect compression level for a zip entry. This is now fixed. Bugzilla Report 62686 * cccheckout would ignore an error of the "ls checkout" command even if failOnError was set to false. Bugzilla Report 63071 Other changes: -------------- * generatekey task now supports SubjectAlternativeName during key generation. * the <modified> selector has a new built-in algorithm 'lastmodified' which computes a value based upon the lastmodified time of the file. * signjar and verifyjar now support the -providerName, -providerClass and -providerArg command line options of keytool via new attributes. Bugzilla Report 65234 * signjar and verifyjar now supported nested <arg> elements for command line arguments that are not supported explicitly by the tasks via attributes. * added several attributes to <javadoc> that support modules. Bugzilla Report 62424 * Jsch library dependency has now been upgraded to 0.1.55. Jsch is the library behind the sshexec and scp Ant tasks. Github Pull Request #84 * ftp task manual has been updated to mention that the remote listing of files honours the followsymlinks attribute. Bugzilla Report 63226
Changes from Ant 1.10.4 TO Ant 1.10.5 ===================================== Fixed bugs: ----------- * Fixes a regression in the "get" task where redirects from a HTTP resource to a HTTPS resource started throwing an exception. Bugzilla Report 62499 * the new allowFilesToEscapeDest didn't work when set to false and archive entries contained relative paths with so many ".." segnments that the resulting path would go beyond the file system root. Bugzilla Report 62502 Other changes: -------------- * Java task now accepts a "sourcefile" attribute to allow single file source program execution, a feature that is introduced in Java 11.
