tzdb Release data2011l

Changelog (from NEWS)

There are just 2 changes that cause different generated tzdata files from
  zic, to Asia/Hebron and Pacific/Fiji - the possible change for Bahia, Brazil
  is included, but commented out.  Compared with the diff I sent out last week,
  this version also includes attributions for the sources for the changes
  (in much the same format as ado used, but the html tags have not been
  checked, verified, or used in any way at all, so if there are errors there,
  please let me know.)
