MELPA is now available as a source of packages to install. The Options menu has a Manage Emacs Packages command.
The Copy Formatted function (formerly Copy Styled as HTML) is now compatible with any Mac application that can insert formatted documents, including Apple's Keynote and Pages, as well as MS Word. The Copy as PDF function exports a small PDF clipping with the region that is widely usable, including in MS Powerpoint.
The color for printing text is now always black unless fontification chooses a different color. If a dark background is used, colors for black-on-white printing are always darkened. (Configure with `htmlize-white-background'.)
Aquamacs 3.3 is compatible with macOS 10.12 Sierra.
Aquamacs is again usuable from a text terminal (start with -nw), with backspace and C-h being recognized properly.
The commandline tools installation function has been updated for Mac OSX ``El Capitan''.
Reported by Steve Ward.
A script called emacs is provided that will start Aquamacs on the command line (in a text terminal) in a mode that starts up rapidly and provides UI compatibility with GNU Emacs (rather than Aquamacs). This is installed by the command Install Command Line Tools (Tools menu, or M-x aquamacs-install-command-line-tool). The emacs script is non-relocatable and needs to remain in the Aquamacs bundle. You may link to it.
filladapt mode is no longer automatically activated, as it hinders compatibility with some modes. Emacs now provides improved filling on its own, see https://www.gnu.org/software/emacs/manual/html_node/emacs/Adaptive-Fill.html. Requested by Win Treese. Filladapt continues to be available to users who need it. It can be loaded by adding (require 'filladapt) to the Preferences.el file.
Apple Emoji symbols can now be displayed.
Cc-mode is about 30% faster in displaying code and scrolling.
Swift-mode (version 0.5.0-snapshot) provided for editing Swift files.
