Bare Bones Software has released version 9.1 of BBEdit, my preferred text editor on the Mac, my favorite XML editor on any platforms, what I'm using to type these very words.
Version 9.1 "now includes a copy of Consolas Regular, an excellent antialiased code editing font. This font is licensed from Ascender Corporation for use only with BBEdit."
New copies cost $125.Upgrades from 9.0 are free.
Mac OS X 10.4 or later is required.
