Release Notes: This release improved portability and increased speed in UTF-8 locales. A period in regular expressions now accepts NUL bytes. ACLs correctly preserved in in-place mode. A new --follow-symlinks option is available when editing a file in-place. Hold-space is reset between different files in -i and -s modes. A new 'z' extension clears pattern space even in the presence of invalid multi-byte sequences. Bugs in multi-byte processing were fixed. More GNU extensions are now turned off by the --posix options, including all GNU extensions to regular expressions.
Release Notes: This release includes all of the changes that will be in GNU sed 4.1, including improvements to POSIX compliancy, portability fixes, bugfixes, better error messages, and better multibyte character set support (the regex matcher is not MBCS-enabled, though). In addition to these features, Perl's '\G' regular expression feature is now supported in both Perl and POSIX regular expressions.
Release Notes: This release has been merged with super-sed and supports all of its features, except for Perl regular expressions. This includes in-place editing, new sed commands, better documentation, and support for changing the case of the characters with the `s' command. The performance and correctness of the regular expression matcher have also been improved.
Release Notes: This release merges all the features in super-sed except Perl regular expressions (including in-place editing, extended test suite, and associated bugfixes), as well as a bunch of extra commands.
Release Notes: The speed on a particular class of regular expressions was improved, the limit on the number of parenthesized groups in a regular expressions was removed, and the ability to pipe a command in the Bourne shell was added.
