sed can be used to substitute a piece of text with some other text.
sed is a stream editor for filtering and transforming text. It can be used to change text strings in files and piped text. The first sed implementation was written in 1974 and the first GNU sed release appeared in 1989.
The GNU version of sed has been creating temporary files with the wrong umask when its -i (to edit files in place) option is used since version 4.2.1. This is a problem when sed is used on certain fuse file systems. GNU sed version 4.8 has a fix for that bug. And that's it, that's the only noteworthy change between GNU sed 4.7 and 4.8.
The GNU sed homepage is at gnu.org/s/sed/. The source for the latest version can be acquired from ftp.gnu.org/gnu/sed/. All the GNU/Linux distributions install sed as part of the base system. A comprehensive manual is available in the Texinfo format, you can read by typing info sed in a terminal.
