As of April 2020, Epsilon 14 is now in beta testing, with a release scheduled for later this year.
Epsilon 13 added new features like Mac OS X support, spell checking, smart indenting for HTML and XML, context-sensitive help, improved source code browsing, dired grep, many more file variables, a mode for Tcl files, line numbers, and many new and improved commands. Here's how to update.
Epsilon 12 added new features like new modes for PHP and VHDL, Unicode support, improved pull completion and commenting commands, font styles, session file and dired enhancements, ssh/scp support, new regular expression options, and many other searching improvements, as well as a new customization method that makes updating much easier.
Epsilon 11 added new features like Visual Basic and Python modes, improved support for embedded scripting in HTML, a hex mode for binary files, an identifier completion feature that saves typing, support for some types of Unicode files, as well as many file differencing enhancements.
Epsilon 10 added new features like Perl mode, support for Linux and FreeBSD, and online documentation in Info and web formats.
Epsilon 9.0 added new features like built-in asynchronous Internet functions, auto ID of file types, NT/2000 concurrent process support, modes for HTML and TeX, and more.
This was the first version of Epsilon for Windows. It included a 32-bit executable for Windows 95/Windows NT, plus others for Windows 3.1 and DOS. Among other new new features, this was the first version to include the complete manual in electronic form.
It included new features like syntax highlighting, command history, and extended file patterns.
Its new features included mouse support and a menu bar.
Some of its new features included on-screen highlighting, pop-up windows, and multi-file searching.
This version featured horizontal scrolling and side-by-side windows.
This was the first version of Epsilon to run on a 32-bit (Unix) platform.
This version of Epsilon introduced undo, tags, and the ability to run very large programs.
This was the first version of Epsilon available for Unix. Two months later, in October 1987, we released the first OS/2 version of Epsilon. (Epsilon was one of the first fifty programs available for OS/2. IBM gave us this lucite plaque. Really.)
This version introduced Epsilon's EEL extension language.
This version introduced the concurrent process buffer, which lets you run programs like compilers and continue editing while they run (even under DOS).
The very first version of Epsilon. Epsilon is over thirty five years old!
