   o RooAbsCache

    - New abstract base class for cache objects associated with RooAbsArgs.
      Caches register themselves with the owning RooAbsArg and propagate
      all necessary state changes and meta information to objects in the cache


   o RooCacheManager

    - Concrete template implementation of RooAbsCache with an interface
      and functionality styled after RooNormListManager. The template class
      provide no special handling for cache contents that includes RooAbsArg
      objects and does not forward hook calls. It is thus mostly intended
      to cache basic types indexed on a normalization/integration configuration


   o RooObjCacheManager

    - Class derived from RooCacheManager<RooAbsCacheElement> that implements
      all proper call forwarding and handling of state and other meta information
      to RooAbsArg objects embedded in the cache elements. To facilitate this
      functionality the RooAbsCacheElement defines a pure virtual method
      containedArgs() that must be implemented to expose its contents to
      the cache manager. The default behavior on a serverRedirect hook is
      to sterilize the cache. OperMode changes are not forwarded by default
      to the cache contents as cached objects do not necessarily have the
      same operation mode (e.g. if the cache contains an integral of its owner).
      Any calls to optimizeCacheMode(), printCompactTreeHook(), and findConstantNodes()
      are forwarded. Moreover, optimizeCacheMode() calls are remembered and
      any objects inserted in the cache after such a call was received will be
      optimized upon insertion in the cache

   o RooAbsCacheElement

    - Abstract base class for objects to be managed by RooObjCacheManager. Each
      object must in addition to its payload implement the containedArgs()
      member function that exposes the RooAbsArg object content to the manager
      for processing. The argument passed to containedArgs() indicates the use
      case for the returned list of objects, allowing the cache payload to
      return different lists depending upon use. This is for most applications
      not required.


   o RooAbsCachedPdf

    - Abstract base class derived from RooAbsPdf for p.d.f.s that implement 
      value caching in a grid over the entire domain of the observables. 
      The base class implements the overall caching logistics and manages
      the RooDataHists and RooHistPdfs that respresent the cached contents.
      Derived classes must inputBaseName() defined a unique name prefix for
      all cache objects, actualObservales() and actualParameters() to
      determined the actual observables and parameters given a set of 
      available observables and fillCacheObject() which should fill the
      RooDataHist cache for a given obs/params configuration with the
      p.d.fs values.


   o RooAbsSelfCachedPdf

    - Abstract base class derived from RooAbsCachedPdf that implements
      all of the required logistics in RooCachedPdf and only require
      derived classes from RooAbsSelfCachedPdf to implement evaluate().
      Any class derived from RooAbsPdf can thus be trivially switched
      to derived from RooAbsSelfCachedPdf and gain the caching functionality.
      

   o RooCachedPdf

    - Concrete class derived from RooAbsCachedPdf that implements
      the caching of an externally provided p.d.f in the constructor.


   o RooFFTConvPdf

    - Concrete class derived from RooAbsCachedPdf that implement generic
      numeric convolution of two input p.d.f.s using FFT technique
      and convolution theorem. Actual FFTs are calculated by FFTW
      through TVirtualFFT interface in ROOT. Present implementation only supports 
      convolution in one dimension, but this will be extended later
      as there are no fundamental limitations in RooAbsCachedPdf nor FFTW.
 

   o RooHistPdf

    - Moved from RooFit to RooFitCore because it is used by caching classes


   o RooProdPdf

     - Use new RooObjCacheManager to store partial objects

     - Fix memory leak (already patched in 15.0.14h)


   o RooDataHist

     - Use new RooCacheManager template to cache partial bin volumes

     - Add new set(),setAllWeights() method to update current weight and all weights
       respectively, for use in cached p.d.f.s

     - Add sliceIterator() that iterates over all bins in a lower dimensional 
       slice of the dataset


   o RooDataHistSliceIter

    - Class derived from TIterator that implements the iteration
      over a slice in a reduced number of dimensions in a RooDataHist


   o RooMsgService

     - Speed up processing of debug streams in cases where no debug streams are active

     - add macros series oocoutX and oocxcoutX that allow to associate message with
       a different object than *this

   o RooRealBinding

     - Interface new setValue method that allows value to be set outside default
       domain, but inside given alternate named range. For use in numeric integrator
       bindings


   o RooAbsRealLValue

     - Add new inRange() method with range name specifier to check against chosen
       range instead of default range


   o RooCmdConfig

     - Fix dangling return pointer problem in decodeStringOnTheFly() method


   o RooNameSet

     - Fix bug in refoll()


   o RooChi2Var, RooNLLVar

     - Add processing of AddCoefRange() named argument


   o RooConvCoefVar

     - Hold p.d.f in proxy without value/shape state propagation to obtain
       correct dependency of RooConvCoefVar through separate set proxy
       with parameters that do have state propagation

     - In getAnalyticalIntegral() ask for integration coefficient specific
       to coefficient (following interface change in RooAbsAnaConv)


   o RooEfficiency

     - Follow interface change in RooCategoryProxy


   o RooAbsAnaConvPdf

    - Use new RooObjCacheManager to hold normalization and coefficient representations

    - Extend getCoefAnalyticalIntegral() interface so that each coefficient
      can have a separate integration configuration

    - Modify makeCoefVars() such that it constructs the RooConvCoefVars with
      actual dependents for each coefficients, rather than inserting dependencies
      of any of the coefficients in each coefficient. This logic requires support
      from the implementation class that is interface through a new member function
      coefVars()


   o RooAbsReal 

    - Add Boolean data member treeVar that indicates is value buffer is also
      branch buffer of a tree. This information is already present in the RooAbsReal
      but is relatively expensive to retrieve and is always needed in the inner
      loop of data set operations. This extra member significantly speeds up operations

    - Remove superfluous _norm[] token in name returned by integralNameSuffix() if 
      no normalization set is supplied.

    - Add a fillDataHist() method that fills a given RooDataHist with a sampling
      of the given function. Added for support of caching p.d.f.s


    - Downgrading warning on non-dependent projection variables in plotOn() to
      a debug level message

    - Remove function optimizeDirty(),doConstOpt(),undoConstOpt(),findCacheableBranches()
      findUnusedDatasetVariables() and findRedundantCacheServers() as part of reorganization
      of optimization functionality.


   o RooAbsCollection

    - Use iterator semantics instead of vector semantics to process RooLinkedList
      contents in assignment operator

    - Add utility function contentsString() returning stl string with names
      of contents


   o RooAddPdf

    - Rewrite cache management using new RooObjCacheManager that holds projection
      integrals, range integrals and supplemental normalization lists


   o RooAbsOptGoodnessOfFit

    - Improve handling of normalization ranges and reference ranges for test statistics
      containing RooAddPdfs. New named argument in fitTo() and RooNllVar::ctor() pass
      reference range for fractions in RooAddPdf components that do not have an explicit
      fixed definition already. Name all normalization ranges explicitly after the
      subrange to which the're applied to avoid name clashes and conflicts if multiple
      normalization ranges are involved.

    - Rewrite informational messages through RooMsgService

    - Implement new constOptimizeTestStatistic() function that signals all test statistic
      components of a RooAbsArg expression tree to perform their constant term optimization

    - Implement new optimizeCaching() driver function that changes default lazy-evaluation-with-caching
      scheme to test statistic scheme where only parameters objects propagate state changes and
      where all components that depend directly or indirectly on observables have lazy evaluation
      disabled. Changes to p.d.f objects are delegated to RooAbsPdf::optimizeCacheMode(). Changes
      to dataset are delegated to RooAbsData::optimizeReadingWithCaching()

    - Implement new optimizeConstantTerms() function that is back end for constOptimizeTestStatistic
      implementation. 


  o RooAICRegistry, RooNormSetCache

    - Remove tracking of allocation cycles of RooArgSets as this scheme is superseded by
      memory pool mechanism for RooArgSet allocation


  o RooMappedCategory

    - Follow interface change in RooCategoryProxy.


  o RooRealMPFE

    - Follow reorganization of optimization functionality: implement new constOptimizeTestStatistic
      function for forwarding to slave processes.


  o RooRealVar

    - Add new setVal() function with range name to facilite setting of values that are outside
      default range, but inside specified alternate range. Needed for numeric integration and
      certain RooAddPdf coefficient projection.


  o RooAbsArg

    - Make state management functions public [is/set][Value/ShapeDirty](), setOperMode90
  
    - Add static _flipAClean boolean to support setACleanAdirty() static method.

    - Implement mechanism for registration of cache objects with base class RooAbsCache.
      Forward all calls to operModeHook(), redirectServersHook(), optimizeCacheMode()
      and printCompactTreeHook() to all caches for further processing
   
    - Define constOptimize() function and provide default implementation that forwards
      to all servers 

    - Implement optimizeCacheMode() function that puts expression tree in optimized
      caching for test-statistics operations (only cache/lazy evaluate nodes that
      do not (indirectly) depend on observables

    - Implement findConstantNodes() function that identifies all nodes that depend
      exclusively on constant observables and >0 observables that are eligible
      for precalculation and caching in test statistics operations by 
      RooAbsOptTestStatistic::optimizeConstantTerms()

    - Define constOptimizeTestStatistics that signal an expression tree that any
      embedded test statistic objects should perform their constant term optimization.
      Default implementation in RooAbsArg forwards call to all servers.


  o RooAbsPdf

    - Use new RooObjCacheManager to manage normalization integrals cache.

    - Process new SumCoefRange() option in fitTo() that sets the coeffient
      interpretation range for all embedded RooAddPdf objects of which
      the interpretation range was not explicitly set

    - Extend interface of fixAddCoefNormalizationSet(): add extra argument
      that controls if AddCoef normalization set are forcibly overruled
      for objects that already have an explicit range setting.

  
   o RooRealIntegral 

    - Add some informational messaging through RooMsgService, rewrite existing ones

    - Speed up numeric summations by precreating the involved RooSuperCategory
      in the ctor rather than in evaluate().

    - Fix bug in dependency insertion: explicitly require servers to be value
      server to avoid pulling in fake dependents.
    
    - Remove obsolete data members

    - Implement new setACleanADirty() function that atomically flips state of
      all AClean objects to ADirty for the duration of the integration step.
      Replaces the much more expensive prepareACleanFunc() that did this
      only for the objects involved.

    - Process factorizing terms in integral only if the list is not empty

    - Process Jacobian terms in integral only if the list is not empty


  o RooAddGenContext

   - Adapt to cache management chanches in RooAddPdf


  o RooNumIntFactory

   - Use STL classes for internal memory management


  o RooSetProxyy

   - Implement operator new() and operator() delete as required because
     RooArgSet implements them 


  o RooAbsGoodnessOfFit

   - Store and forward AddCoefRange information for embedded RooAddPdf objects

   - Implement constOptimizeTestStatistic() and forward to components


  o RooErrorVar

   - Follow inRange() interface change in RooAbsRealLValue


  o RooConvGenContext

    - Adapt code to make it work with both RooAbsAnaConv objects and
      the newly introduced RooFFTConvPdf


  o RooMinuit

    - Follow reorganization of optimization functionality


  o RooProjectedPdf

    - Store projection using new RooObjCacheManager


  o RooGlobalFunc

    - Add RooFit::SumCoefRange() named argument for RooAbsPdf::fitTo() 
      and RooNLLVar::ctor() and RooChi2Var::ctor()


  o RooClassFactory

    - Extend existing makePdf(),makeFunction and makeClass() functions
      to also accept RooAbsCategory arguments, to accept an optional string
      inserted as the return value expression inserted in the 
      evaluate() method of the class created, as well as as option string
      specifying one or more analytical integrations of the given function
      expression that will be advertised in the generated getAnalyticalIntegral()
      code and implemented in the generated analyticalIntegral() code

    - Add makeAndCompileFunction() and makeAndCompilePdf methods that
      generate the code and immediate compile it through ROOTs ACliC interface.
      These functions have a simpler interface because the list of arguments
      of the function to be created can be specified as a const RooArgSet&
      rather than a string with a list of names, thus making it easier
      for on-the-fly definition of compiled objects.

    - Add defineFunction() and definePdf() methods define and compile
      a function/pdf using the above functions and immediately instantiate
      an object of the given type passing the specified RooArgSet arguments
      to the constructor of the object. These functions make a compiled
      equivalent of RooFormulaVar based on the TFormula interpreter, i.e.

           RooAbsReal* f = new RooFormulaVar("f","D(1-2w)",RooArgSet(D,w)) ;

      becomes
       
           RooAbsReal* f = RooClassFactory::defineFunction("f","D(1-2w)",RooArgSet(D,w)) ;

   
  o RooAbsCategory

   - Add Boolean data member treeVar that indicates is value buffer is also
     branch buffer of a tree. This information is already present in the RooAbsReal
     but is relatively expensive to retrieve and is always needed in the inner
     loop of data set operations. This extra member significantly speeds up operations

   - Construct explit clean name for TBranch name if node is cached, equivalent
     to what is done in RooAbsReal. Needed because new constOptimizer can also
     cache RooAbsCategory objects


  o RooArgSet

   - Implement operator new() and operator delete() to implement memory pool scheme
     for RooArgSets. The goal of this implementation is to insure that two RooArgSet
     pointers are _never_ the same. This allows to RooNormSet cache manager to safely
     and quickly index integration and normalization configurations by evaluating
     the contents of a RooArgSet only the first time it sees it.


  o RooSimultaneous

   - Implement caching of partial integrals using new RooObjCacheManager

   - Following interface change in RooCategoryProxy ;


  o RooAbsData

   - Defined pure virtual methods optimizeReadingWithCache() and allClientsCached()


  o RooTreeData

   - Implement optimizeReadingWithCache() which determines given a p.d.f to be
     evaluated and a list of the nodes that are cached for it, which observables
     in the dataset are no longer required because they are either not an observable
     of the p.d.f, or they exclusively feed nodes that are cached. Reading of these
     observables is disabled through SetBranchStatus().
  
   - Move allClientsCached() utility function here from RooAbsReal.


  o RooCategoryProxy

   - Remove const char*() conversion operator in favor of a const char* label() method
     to remove possibly ambiguities in C++ math expressions involving category proxies.


  o LinkDef3.h

   - Add newly defined classes

       (fixes oberved crashes of all numeric integration and configuration business)


   o  RooRealVar

     - Back out change that setting asymmetric error clear symmetric error and vice versa.
       It causes just too much confusion...

      addition of missing return statements to make all code
      compile cleanly with '-Wall -Wno-parentheses'

  o RooAbsFunc

    - Make resetNumCall() const

  o RooAbsIntegrator

    - Add calculate() method that wrape integral() between
      profiling code the track the number of integrand
      function calls

  o RooIntegrator1D,RooImproperIntegrator1D,RooSegmentedIntegrator1D,
    RooSegmentedIntegrator2D,RooMCIntegrator

   - Change interface to take RooNumIntConfig class instead
     of now deprecated RooIntegratorConfig class

   - Add member function that advertise capability of the integrator:
     canIntegrate1D,2D,ND,OpenEnded()

  o RooAbsReal

   - Change normalization integral management classes
     (createIntegral(), (set)defaultIntegratorConfig(),
     (set)specialIntegratorConfig()) to work with new
     RooNumIntConfig class.

  o RooArgSet

   - Add new convenience functions get/setRealValue(),
     get/setCatLabel/Index(), get/setStringValue() to
     manage common content of RooArgSet.

  o RooConvCoefVar, RooConvGenContext

   - Support class name change RooConvolutedPdf -> RooAbsAnaConfPdf

  o RooCustomizer

   - Add function setCloneBrancSet() that allows to specify
     an external set that takes ownership of the cloned branch
     nodes so that customized objects can live beyond the lifetime
     of the RooCustomizer instance

  o RooImproperIntegrator1D

   - Add code to handle limit scenario changes (closed to open ended
     and vice versa) on the fly

  o RooIntegrator1D

   - Add fixSteps option to terminate integral calculation after
     fixed number of steps w/o extrapolation. This is more robust
     for certain types of integrals

  o RooRealIntegral

   - Change interface to take RooNumIntConfig class instead of
     RooIntegratorConfig class

   - Delegate instantiation of numeric integration engines to
     new class RooNumIntFactory

  o RooNumIntConfig

   - New class to store configuration of numeric integator engines.
     This class has a brief common section with common properties
     like absolute and relative precision convergence criteria,
     and a section with implementation specific details for each
     engine in the form of a RooArgSet. The default settings for
     each existing engine are automatically added to the defaultConfig()
     instance during run-time initialization

  o RooNumIntFactory

   - Factory class for numeric integration engines. Each existing
     integrator engine automatically registers with the factory
     stating its capabilities (1D,2D,ND / Open-ended). The
     createIntegrator() function instantiates an integrator
     appropriate for a given problem. In case more than one
     integration engine can solve the given problem the (user
     changable) information in the RooNumIntConfig passed along
     with the call is used.

  o RooGaussKronrodIntegrator1D

   - New integrator engine based on Gaussian quadrature techniques.
     This implementation, taken from GSL 1.5 implements the Gauss-Kronrod
     techniques where the error on the integral is take from the difference
     between the Gauss and Kronrod techniques. These techniques share common
     sampling points allowing to calculate the error without additional cost.
     This integrator applies the 10,21,43, and 87 point rules in succession
     until the desired accuracy is reached. Open-ended integrals are
     automatically handled through a x -> 1/x coordinate transformation

  o RooAdaptiveGaussKronrodIntegrator1D

   - New integrator engine based on Gaussian quadrature techniques.
     This implementation, taken from GSL 1.5 implements the Gauss-Kronrod
     techniques where the error on the integral is take from the difference
     between the Gauss and Kronrod techniques. These techniques share common
     sampling points allowing to calculate the error without additional cost.
     This integrator applies the 10,21,31,41,51 or 61 point rule and
     recursively subdivides the integration domain until the desired accuracy
     is reached. For integrands with integrable singulaties the Wynn epsilon
     rule can be selected to speed up the converges of these integrals. Open
     ended integrals are automatically handles through a x -> 1/x
     coordinate transformation

  o RooNumConvPdf

    - New operator PDF class that implements numeric convolution of
      any two PDFs. The calculation of the convolution integrand
      is implemented in the auxiliary class RooConvIntegrandBinding,
      which in turn can be integrated with any 1-D numeric integration
      engine. The default integration method for convolution integrals
      is the adaptive Gauss-Kronrod method, which appears to give the
      most stable results. By default the integration is performed
      from -inf to +inf, but can optionally be restricted to a sliding
      window using the setConvolutionWindow class, useful for relatively
      narrow resolution PDFs.

  o RooAbsAnaConvPdf

    - New name of RooConvolutedPdf to clearly distinguish its functionality
      from RooNumConvPdf

 o RooAbsArg

   - Keep track of cloning with attributes. add isCloneOf()
     method to test if objects are clones

 o RooAbsCollection

   - Implement check of 'unique-name rule' in snapshot() method.
     Disabled for the moment as we violate this rule in benign ways
     in several places in the core code. This needs to be fixed first

 o RooAbsPdf

   - Add methods to specify numerical integrator configuration to be
     used in normalization
     There is one global default configuration (RooIntegratorConfig object)
     and each PDF can optionally have a private configuration that
     overrules the default one.

 o RooAddPdf

   - Add on-the-fly transformations for coefficients between
     normalization sets.  Users can now specify a
     'reference normalization' via fixCoefNormalization() in
     which the fractions will always be interpreted.
     If no such reference set is specified the default behaviour
     will prevail: the interpretation depends on the current normalization.

 o RooAbsReal

   - Change plotOn() such that when a PDF containing RooAddPdfs
     is projected with data, an appropriate reference normalization
     is set for each, if no user-supplied reference normalization
     was set. This ensures intuitive behaviour of plotOn() for RooAddPdfs

   - Add easy-to-use wrapper function for createProjection()

 o RooErrorVar

   - Add readFromStream/writToStream()

   - Declare fundamental

 o RooImproperIntegrator1D,RooIntegrator1D

   - Add constructors from RooIntegratorConfig

 o RooMCIntegrator

   - Add constructor from RooIntegratorConfig

   - Make #iterations and #call per iteration for grid refinement
     and integration configurable parameters

 o RooProdPdf

   - Complete rewrite. Now _all_ permutations of integration/normalization
     are correctly performed. New implementation uses a product
     of partial integrals created with pdf->createIntegral()

 o RooRealIntegral

   - Add optional RooIntegratorConfig to ctor and pass to numerical
     integrator ctors in various places

 o RooSetProxy

   - Fix server management for owning set proxies

 o Many classes

   - Anticipate potential failure of snapshot() due to unique-name
     rule enforcement and handle such situations appropriately

   parameters clearer.
 - modify signatures of 2D createHistogram() methods for consistency
   with 1D methods.
 - add new createProjection() and fillHistogram() methods.

RooAbsPdf:

 - comment out plot() methods

RooRealIntegral:

 - make normVars ctor parameter const
 - fix bug in printToStream (was always verbose for AbsReal sub-object)
 - add info message before starting an MC integration (>1 dim)

RooAbsCollection:

 - add newline to OneLine printToStream() (this might break some other
   printout but is the expected behavior...)

  Generalize RooArgSet to RooAbsCollection and introduce RooArgList
  and corresponding proxy. Introduce RooArgList where appropriate
  as replacement of a TList of proxies, eliminate all use of TList
  inherited functions in RooArgSet/List.

  Some optimizations implemented following profiling studies

  Various fixes for compilation with Solaris CC 5.0

  o RooAbsArg

    - Change signature of server management function to use RooAbsCollection
      instead of RooArgSet
    - Add proxy management support for new RooListProxy class

  o RooAbsPdf

    - Disable use of RooNameSets as optimization attempt. It appears
      to cost more time than it saves

  o RooAbsProxy, RooArgProxy, RooAbsReal, RooAcceptReject,
    RooDataHist, RooFormula, RooFormulaVar, RooGenCategory,
    RooGenContext, RooGenericPdf, RooPlot, RooRealIntegral,
    RooResolutionModel, RooSetProxy, RooSuperCategory, RooTreeData

    - Follow RooAbsArg member function signature changes

  o RooAddPdf, RooConvolutedPdf, RooFitContext, RooSimFitContext,
    RooFitResult, RooPdfCustomizer, RooProdPdf,

    - Change implementation from using TList to using RooArgList

  o RooAbsCollection

    - New abstract base class for collections of RooAbsArgs. This
      class contains mostly code from the former RooArgSet implementation

  o RooArgSet

    - Re-implement as derived class of RooAbsCollection. A RooArgSet
      cannot contain duplicates (as before), but also doesn't give
      random access (by index) to its member elements

  o RooArgList

    - New implementation of RooAbsCollection that allows duplicates
      in the list, allows sorting and lookup by index.

  o RooListProxy

    - Proxy version of RooArgList, similar to RooSetProxy. To be used
      as data member of RooAbsArg implementation to hold external
      RooAbsArg references.
