After two years of development, the release of the fullscreen console window manager (terminal multiplexer) GNU screen 4.9.0 has been published, allowing the use of a single physical terminal to work with multiple applications, each assigned separate virtual terminals that remain active between different user sessions.
Among the changes:
- An escape sequence ‘%e’ has been added to display the used encoding in the hardstatus line.
- The openpty() call has been utilized for terminal operations on the OpenBSD platform.
- The vulnerability CVE-2021-26937 has been fixed, which caused crashes when processing certain combinations of UTF-8 characters.
- A limit of 80 characters has been set for the session name (previously, using excessively long names led to failures).
- The issue with ignoring the username specified via the ‘-X’ option has been resolved.
