Yesterday we highlighted the release of TextWrangler 4, the wonderful free text editor from Bare Bones Software. Here’s a closer look at the new stuff you’ll find in this update.

We’re a big fan of BareBones Software here and endorse their incredible BBEdit app whenever we have the chance, but if you don’t want to parcel out fifty bones for it, BareBones has just done everyone a solid and brought over many of the new features from BBEdit 4.0 to their free, powerful text editing software, TextWrangler.

Mac OS X developers have been given a few extra months to accept the Mac App Store app sandboxing requirements… or to forget about selling their apps through Apple’s store altogether.

Originally, the deadline was November 1st, but Apple has since uncharacteristically extended the deadline to March 1, 2012. After that, all apps sold in the Mac App Store must use Mac OS X Lion’s new sandboxing framework. That framework is another thing Lion had adopted from iOS and is meant to increase security on the Mac.

With the deadline extended, developers now have about four months to decide on whether they will support sandboxing in their apps. The problem? If they do, some apps will become just shadows of their former selves.

TextWrangler is a well-named application. It’s there to do a particular job, and that job is wrangling text.
