One of the most vesatile IDE's created specifically for scripting languages has just been upgraded to support section lists, unit test integration extensibility, the Zend framework and source control improvements.

I have been using the Komodo IDE since its inception and have been pleased to watch it grow from a fairly simple Perl, Python and Tcl editor to encompass sophisticated project management, version control, expanded language support and remarkable performance and debugging gains over its maturity lifespan and have continually been pleasantly surprised by the additions each point release brings to developers.  There's a reason why Komodo is a consistent Jolt nominee; not only is it a solid development environment, but its active evolution frequently embeds new innovations and notable improvements to the product. The fact that it runs identically on the Windows, OSX and Linux platforms is icing on the coding cake.

The ActiveState Komodo 4.4 release is a free upgrade for registered Komodo 4.x users.  More information about this release can be reviewed on the ActiveState Komodo website, as well as screencasts of the IDE in action.
