  Upgrade to version 1.2.8

       has been disabled until further notice. This impacts ContextJNDISelector
       and insertFromJNDI element in configuration files.
     + Also in response to log4Shell/CVE-2021-44228, all database (JDBC)
       related code in the project has been removed with no replacement.
     + Note that the vulnerability mentioned in LOGBACK-1591 requires write
       access to logback's configuration file as a prerequisite. The
       log4Shell/CVE-2021-44228 and LOGBACK-1591 are of different severity
       levels. A successful RCE requires all of the following conditions to be
       met:

  - write access to logback.xml

  - use of versions lower then 1.2.8

  - reloading of poisoned configuration data, which implies application
         restart or scan='true' set prior to attack
