l2p20.03.00 build 1 - 1 June 06

== Level 2 DAQ: hirosky/mverzocc
l2admin                   l2-02-01-00 <- l2p20-br-01
  Use the Run2B version of the L2 calorimeter workers....
l2online                  l2-01-02-00 <- l2p20-br-01
  The wrong type of tag was used for l2p20.01.01.
  There is no actual code change.


== Level 2: cwiok
l2cal2bbase               p20-br-01 <- new
  Included for the first time - Run2B version of the L2 calorimeter worker(s)
l2cal2bemworker           p20-br-04 <- new
  Included for the first time - Run2B version of the L2 calorimeter worker(s)
  Include the right version of the Run2B L2 EM worker with the latest
    version of the EM likelihood
  Add protection against division by zero
l2cal2bjetworker          p20-br-01 <- new
  Included for the first time - Run2B version of the L2 calorimeter worker(s)
l2cal2bworker             p20-br-01 <- new
  Included for the first time - Run2B version of the L2 calorimeter worker(s)
l2calemworker             p20-br-01 <- v03-00-01
  Set the likelihood (Run2B) to zero and bump up the version of
  the EM object for compatibility with the latest version of IOGEN object.
l2caljetworker            p20-br-01 <- v03-00-02
  Set the tau energy and ratio to zero and bump up the version of
  the jet object for compatibility with the latest version of IOGEN object.
l2gblem                   p20-br-02 <- p20-br-01
  Fixed typo LIKELHOOD/LIKELIHOOD
l2gblgeneric              p20-br-02 <- p20-br-01
  Fix a possible problem arising when one of the two cuts (on sphericity or
  aplanarity) is disabled (i.e. cut value = 0)
l2gblmuon                 p20-br-01 <- v00-02-02
  Tagged (et > _minEt) bug fix that was only in p17 branch
l2gbltrack                p20-br-03 <- p20-br-01
  Set base objects in l2btag tool
l2gblworker               p20-br-04 <- p20-br-01
  Modifications for L2 splitting/oring (new version of L2 global header,
  with different mechanism for taking care of mapping of trigger bits,
  new classes for handling scripts/superscripts). Add new L2 global objects
  for L2 sphericity and taus. To ensure backward compatibility with
  Run2A data add copies of the L2 global header objects and the
  relevant classes needed for reading the data.
l2io                      p20-br-03 <- p20-br-01
  Changes for Run2B: add quantities used for tau ID to the L2
  preprocessor jets and the EM likelihood to the L2 preprocessor
  EM objects. Modify the L2 global header to handle L2 splitting/oring.
  Add L2 global objects for tau and sphericity.
  Introduce copies of the Run2A L2 header objects for backward
  compatibility. Modify the precision of the STT b-tagging variable.
  Fix a synchronization error occurring online when dealing with unknown
  channels (the bug fix hadn't been ported to the development branch during
  the P17 development)
l2message                 p20-br-03 <- l2-01-01-00
  Remove any trace of the iogen code in the l2message package area
l2parser                  p20-br-02 <- v00-02-04
  Increase buffer sizes (needed for L2 oring/splitting)
l2workerbase              p20-br-01 <- v01-00-04
  Remove iogen from path of automatically generated include files

== Level2: cwiok/mverzocc
l2cal2bemworker           p20-br-05 <- p20-br-04
  bug fixes for the calculation of the EM likelihood 
 (and protections against divide by zero)
l2cpsworker               p20-br-01 <- v03-00-01
  Synchronization of l2p20.03.00 tags with l2p17.09.00 ones.
l2gblworker               p20-br-05 <- p20-br-04
  increase the buffer size for ETAFILTERS (need more to run V15
  triggerlist)

l2p20.03.00 build 3 - 9 June 06

== Level2: mverzocc
l2cal2bjetworker          p20-br-02 <- p20-br-01
  Fix a bug in the L2 jet worker. When finding the 2nd leading tower
  (used for tau identification) the algorithm didn't enforce the
  requirement that the 2nd leading tower is near the leading tower
  inside the jet.
