GNU Nano 2.4.0 Brings Complete Undo System, Linter Support & More
This first stable update to GNU Nano in years is codenamed "Lizf" and brings a wide variety of changes. Among the new features of this alternative to Vim and Emacs is a fully-functionality undo system, Vim-compatible file locking, linter support, formatter support, flexible syntax highlighting, and many bug-fixes.
The GNU Nano 2.2 series was introduced all the way back in 2009, so there's quite a lot of work found in this release unless you were previously using the Nano 2.3 series.
The Nano 2.4 announcement was posted today to nano-devel.
