• (ms) Bob Kleemann reported that logdie() in wrapper classes
  printed incorrect caller lines. Fixed by adding
  caller_depth_offset() utility to Log4perl.pm.
  
• (ms) Meir Guttman reported a use case for logging messages
  with dynamic levels on log4perl-devel@lists.sourceforge.net.
  Added to manual page.
  
• (ms) Implemented suggestion by Neil Hooey to check for and report
  undefined message elements before they're assembled in Appender.pm
  and a warning is issued without a proper code location:
