Name : jansi
Product : Fedora 34
Version : 2.1.1
Release : 4.fc34
URL :   http://fusesource.github.io/jansi/
Summary : Generate and interpret ANSI escape sequences in Java
Description :
Jansi is a small java library that allows you to use ANSI escape sequences
in your Java console applications. It implements ANSI support on platforms
which don't support it like Windows and provides graceful degradation for
when output is being sent to output devices which cannot support ANSI sequences.

--------------------------------------------------------------------------------
Update Information:

This update provides log4j 2.16.0, to address the critical vulnerability
CVE-2021-44228 ("Log4Shell"). Note with 2.16.0, JNDI is entirely disabled by
default; to use it, you must set `log4j2.enableJndi` (please carefully consider
potential security issues before doing so). The updated jansi adds (back) a
feature, `AnsiRenderer`, which the newer log4j requires; this is the only change
to jansi. For other changes in log4j 2.16.0, see the [upstream
changelog](  https://logging.apache.org/log4j/2.x/changes-report.html#a2.16.0).
Most changes are compatible enhancements or bug fixes, but there may be some
behaviour changes.
--------------------------------------------------------------------------------
ChangeLog:

* Mon Dec 13 2021 Adam Williamson - 2.1.1-4
- Backport patch to bring back AnsiRenderer
