PyDev 5.0.0 is now available for download.
The major feature in this release is that the PyUnit view will now persist its state across restarts ( personally, I find this pretty handy as I usually try to leave a failing test to be solved so that I know where I stopped ).
Also, this release requires Java 8 to be used ( if you need an older version, you can access the update site for older versions at: http://www.pydev.org/update_sites ).
As a note, if you're unsure on how to update your system java vm ( or it's not possible to ), you can dowload a .tar.gz version from http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html, extract it somewhere and point Eclipse to use it following the info from: http://wiki.eclipse.org/Eclipse.ini ( or just use LiClipse, which has the latest PyDev bundled for a hassle-free installation with many extra goodies ).
See: http://pydev.org for more details on this release ( as a note, PyDev 4.6.0 was previously released with the same contents, but was re-released under 5.0.0 to signal the major change on the required Java VM ).
