GNU ed is an 8-bit clean implementation of the POSIX line-oriented text editor. Ed is the "standard" text editor in the sense that it is the original editor for Unix, and thus widely available. For most purposes, however, it is superseded by full-screen editors such as GNU Emacs or GNU Moe.
Release Notes: No user-visible changes were made. Ed now stops reading stdin when reaching the real End Of File the first time. Previously it needed to reach EOF twice.
Release Notes: Shows the "Try 'ed --help' for more information." message if a bad option is given on the command line. Quote characters in messages have been changed as advised by GNU Coding Standards. The description of address offsets in the manual and a link to the Bash manual have been fixed. The configure option "--datadir" has been renamed to "--datarootdir" to follow GNU Standards. The target "install-bin" has been added to the Makefile.

Release Notes: Displaying of null characters by the "l" command has been fixed. The condition deciding when to show the message "Newline appended" has been corrected. The "modified" flag is now set when reading a non-empty file into an empty buffer. An error that prevented using NUL characters in regular expressions has been fixed. Ed now signals an error if it can't create a shell process when executing a shell command. Ed now flushes stdout/stderr before reading a new command. All command-line options are now documented in the man page.
