• (ms) [RT 60665] HUP handlers are stacked on top of each other now,
  to make sure that multiple file appenders recreate multiple
  files and not just one (patch provided by Karen Etheridge).
  
• (ms) [RT 60197] Fixed uninitialized value warnings with
  the multiline appender and provided a test case (patch provided
  by Karen Etheridge)
  
• (ms) [rt.cpan.org #59617] Fixed system-wide threshold without appender
  thresholds. Bug reported by Dmitry Bigunyak.
  
• (ms) [rt.cpan.org #24884] Using require() instead of incomplete
  logic in L4p::Util::module_available(). local DIE
  handler takes care of user-defined DIE handlers
  ignoring $^S (suggested by Eric Wilhelm and others).
  
• (ms) [rt.cpan.org #60386] Fixed init_and_watch() which
  double-bumped the caller_level and led to uninitialized
  values in the pattern layout. Thanks to Mitja Bartsch for
  the report.
  
• (ms) Applied patch by Karsten Silkenbäumer to add an optional
  $log_dispatch_level to create_custom_level(). Updated
  documentation.
