  o RooBCPEffDecay,RooBMixDecay

    - Ctor: change from RooArgSet to RooArgList in declareBasis()
      calls to correctly handle cases where dm and tau are the
      same parameter (e.g. zero)

  o RooGaussModel

    - Fix bug in analytical normalization of sinBasisPlus/Minus

  A large number of small fixes and improvements

  o Roo1DTable

    - Modify Print() behaviour. Standard print will
      only show non-empty fields, verbose shows all fields

  o RooAbsArg

    - Change getParameters so that it can accept 0 as
      dataset pointer (implies no dependents)

  o RooAbsPdf

    - Follow plotOn() changes in RooAbsReal

  o RooAbsReal

    - Add optional const RooArgSet* projData argument to
      plotOn(). Projected dependents that appears in this
      dataset, if specified, will be projection via summation
      over data instead of integration.

    - Add clipInvalid option to bindVars() and propagate to
      RooRealBinding

    - Modify cleanBranchName() to truncate 'clean names'
      (which are used for the TTree branch) to 63 chars
      as cannot handle such cases (SEGV). In case name
      is longer than 63 chars, truncate name at 46 chars
      and suffix with _crc followed by hex representation
      of CRC32 checksum of the full name.

    - Add crc32() method to calculate the checksum of a string


  o RooAddModel,RooAddPdf

    - Do not evaluate PDF components multiplied by a zero coefficient

  o RooAddPdf

    - Fix DIV0 in analyticalIntegral if number of expected events
      for all PDFs combined totals zero

  o RooArgSet

    - Add ability to readFromStream and readFromFile to optionally
      flag read arguments with a user specified attribute
      (Mostly useful to determine which elements have _not_ been read)

  o RooConvolutedPdf

    - Change declareBasis() signature from a RooArgSet& to a RooArgList&
      to correctly handle cases where the names of parameters are identical
      (e.g. tau=zero and dm=zero for prompt background models)

    - Expand logic in RooGenContext. Add additional requirement for
      use of optimized generator context: both the physics pdf and
      the resolution model must support direct generation of the
      convolution variable.
      (Still have to fix RooAddModel/Pdf for cases where all components
       can do direct generation)

  o RooCurve

    - Deploy RooRealBinding::clipInvalid feature to zero plotted functions
      outside the validity range of their dependents

    - Add extra points at (xlo,0) and (xhi,0) to obtain correct filling
      pattern when using the 'F' draw option.


  o RooCustomizer

    - Add warnings for multiple split or replace rules on the same leaf


  o RooDataSet

    - Make read() take a const RooArgList& instead of a RooArgList&
      and immediately make temporary copy for internal use.

    - All constructors with string based cut: add default empty cut.

  o RooFitContext

    - Ctor: Compare limits on dependents in PDF and dataset if limits
      of PDF are smaller and fully contained in those of the dataset,
      adjust the dataset ranges in the internal copy and reject events
      outside the PDF limits. If PDF ranges are not identical or fully
      contained in dataset limits, give error message and abort.

    - In fit() fix handling of parameters handed to TMinuit: set pmin/pmax
      to the parameter value for constant parameters. For floating parameters
      with open limits and without error, use 1/10 of the plot range
      instead of 1/10 of the fit range.

  o RooFormula,RooFormulaVar

    - Change RooArgSet to RooArgList to pass formula parameters.
      This allows construction of formulas with ordinal references
      for list of parameters with multiple occurrences of the same
      variable.

  o RooRealBinding

    - Add clipInvalid option, specified in ctor. If set, loadValues()
      will first check if the values to be loaded are in the limits
      of the bound objects dependents. If not the values are not loaded
      and an invalid flag is set. If the invalid flag is set operator()
      will return 0.

  o RooRealVar

    - Add various 'named parameter' functions on a trial basis

  o RooSimFitContext

    - Gracefully handle RooSimultaneous PDFs with missing PDFs.

  o RooSimGenContext

    - Forgot to set index state in theEvent RooArgSet when generating
      the index category

    - Remove forced normalization of index state in evaluate()

    - Remove dummy plotOn() method and specialized plotOn() with data
      method as projection over the index state can now be handled
      the regular plotOn method. Overload RooAbsPdf::plotOn to
      force caller to specify projection dataset for the index category
      if projection over the index category is requested

  o RooTable

    - Remove print(), add default Print(Option_t *), and reimplement
      printing via inheritance from RooPrintable


  o RooTreeData

    - In loadValues(RooTreeData*) explicitly check isValid() of
      each element of _vars after copying. If any is invalid,
      reject the event.

    - In table() change simple clone of tableVar to deep clone.
      Implement use of optional cut string (accidentally omitted sofar)

  o RooTruthModel

    - Add highly trivial direct generator for the convolution variable


  o RooDataProjBinding

     - New lightweight binding between an RooAbsReal and a dataset
       that returns the projection of the real over the dataset
       via summation. If the dataset only contains category variables
       an supercategory of all the datasets categories is created
       and the data is summed (with appropriate weights) over the
       supercategory states instead of over every event.

  void TF1::RejectPoint(Bool_t reject=kTRUE)
  Bool_t TF1::RejectedPoint()

The function TF1::RejectPoint may be used in a user fitting function
to reject points. The fgRejectPoint is automatically reset by Root.

A new member function TF1::IsInside has been added.
Currently it returns kTRUE if the point is inside the function limits.
This function is redefined in TF2 and TF3.
The main purpose of this function is to give additional possibilities
in functions deriving from TF1. For example, if a function is only
defined in some specific non-contiguous ranges, this could be
implemented in a class deriving from TF1 and simply redefining
the function TF1::IsInside.

Of course, the matrix condtioning I added only will work for a symmetric
matrix (as encountered in all fitting problems).

So I added:
1) test to see that matrix is symmetric, only then condition matrix
2) I had also forgotten to correct the resulting determinant.
   Here a caveat: if you pump in a(10x10) matrix with 1e-100 on
    diagonal, inversion will be ok but the final returned determinant
    will have underflowed

This makes sure that CopyTree does not operate on a left over
from a Draw command.  Before this patch doing:
        mytree->Draw("fPx","fPx>10);
        mytree->CopyTree("");
was the SAME as
        mytree->CopyTree("fPx>10");
