Bare Bones Software has announced the release of TextWrangler 4.0, a new version of their free text editing software, based on the same core technology that powers their flagship BBEdit software.

TextWrangler 4.0 touts new editing and disk browser window layouts, switchable syntax color schemes and preservation of open documents on relaunch. A new Preferences window and new Setup window make it easier to customize and configure how to make TextWrangler work the way you want it to.

Filtering and automation has been streamlined, support for Verilog and VHDL has been added, and a new “Open File By Name” feature produces search-as-you-type results. Performance has been improved and user interface changes have been made as well.

What’s more, TextWrangler is still absolutely free. It’s available either through Bare Bones’ Web site or through the Mac App Store.

System requirements call for Mac OS X 10.6 or later.
