Jython 2.5.2 Release Notes

The following features have been added and bugs have been repaired for 2.5.2. For a look at the complete roadmap for Jython along with links for the PEPs and other information, please look at the roadmap:

New Features

The socket module now includes ipv6 support

The socket module now also includes Internationalized Domain Names (RFC 3490) support on Java 6

Performance improvements around method invocation. 2.5.2 runs the richards benchmark 3x faster and the pystone benchmark 20% faster than 2.5.1

The posix/nt module was rewritten in Java and the performance of its often performance-critical stat function has significantly improved

Improved OSError errno messages on Windows

Slightly improved startup time (ongoing Issue #1380)

Better readline module emulation (required for IPython support)

Python functions can be directly passed to Java methods that take a single method interface (such as Callable or Runnable)

Add google indexer (by Yin Wang and Steve Yegge)
