Remove
using namespace std;
from Riostream.h, which has huge consequences for all of ROOT.
Riostream.h is now a simple wrapper for fstream, iostream, iomanip for backward compatibility; Riosfwd.h simply wraps iosfwd.
Because of templates and their inline functions, Riostream.h needed to be included in headers, too (e.g. TParameter.h), which violated the assumption that Riostream.h is not exposing its using namespace std to headers.
ROOT now requires R__ANSISTREAM, R__SSTREAM, which does not change the set of supported compilers.
Without "using namespace std", several identifiers are now prefixed by std::; e.g. roofit/* source files now have a using namespace std to keep their coding style.
TFile::MakeProject() now generates "using namespace std" to convert the CINT-style class names into C++ ones.

- Like "SetPoint" the method "Apply" modifies the graph content.
So, a logic similar to the one implemented in SetPoint should
be done, ie:
1) if fHistogram exists it is reset.
2) if gPad exist a gPad->Modified() is issued.

- The following macro generated wrong C file:
{
TGraphErrors *ge = new TGraphErrors(2);
ge->SetName("aaa"); // <<< without this it works
ge->SetPoint(1, 1, 1); ge->SetPoint(2, 2, 1);
ge->Draw("ap*");
gPad->Update();
ge->SavePrimitive(cout);
}

From Olivier and me:
Split the TGraph classes to move the graphics code to separate classes.
These classes will be moved to the hist directory once the classes will be ok.
The TGraphs are painted via the TVirtualGraphPainter class and its concrete
implementation TGraphPainter.
At the difference of the TH1 classes for which a different painter is created
when drawing each histogram, one single TGraphPainter class is created.
The TGraphPainter class does not have internal state, all the information
from TGraph is passed to the drawing functions via parameters.

Change TGraph::ComputeRange to compute the x/y range of the graph.
Move code previously in TGraph::PaintGraph or TGraph::PaintGrapHist to TGraph::ComputeGraph.
The functions like TGraphErrors::ComputeGraph call first TGraph::ComputeRange.

- The signatures of the two SetPointError methods were incomplete. The shift
values in the various directions were missing. To preserve the backward
compatibility, the missing parameters have been added with default value = 0.
The new signature is now used in SavePrimitive which allows a correct saving
of the TGraphBentErrors.

- The SavePrimitive mechanism did not work properly. In particular
it was not possible to save various kind of graphs in several multigraph
in the same macro. Also in case of TGraph the generated macro was wrong
(Add() was missing).
- Make the help in the THTML style

from Axel:
Change the signature of SavePrimitive from
void SavePrimitive(ofstream &out, Option_t *option);
to
void SavePrimitive(ostream &out, Option_t *option = "");
With this change one can do, eg
myhist.SavePrimitive(std::cout);
WARNING: do rm -f tree/src/*.o

From Anna Kreshuk:
- TLinearFitter class: Linear fitter is used to fit a set of data points with a linear
combination of specified functions (with or without weights). The "linear" in the name
stands for "linear in parameters", not variables. The main advantages,
compared to a general non-linear fitter, is that the linear fitter is considerably
faster and doesn't require setting the initial values of parameters.
The linear fitter can be used directly or through TH1::Fit and TGraph::Fit functions
When it's used directly, functions of more than 3 dimensions can be fitted.
- TFormula: a new data member fLinearParts and methods to process it are added. Now
one can create a function of the type that can be fit by the linear fitter.
Example: TFormula f("f", "x++sin(x)") is equivalent to
TFormula f("f","[0]*x + [1]*sin(x)"), but if a TH1::Fit or a TGraph::Fit is performed
with the 1st formula, it goes through the linear fitter, if it's performed with the
2nd formula, it goes through Minuit.
- TMultiGraph class: the Fit method is implemented, allowing to fit all the graphs
of a multigraph simultaneously
- TGraph, TGraphErrors, TGraphAsymmErrors, TGraphBentErrors - functions GetEXhigh(),
GetEXlow(), GetEYhigh(), GetEYlow() implemented to simplify the GraphFitChisquare()
function of the TFitter class
- TH1, TGraph, TGraph2D, TMultiGraph - changes in the Fit functions, allowing to use
the linear fitter. Fitting with "polN" functions redirected to use the linear fitter,
in cases where no options, except "range", are specified.

From Olivier:
New options in TGraphErrors::Paint, TGraphAsymmErrors::Paint and in
TGraphBentErrors::Paint :
if option "3" is specified a filled area is drawn through the end
points of the vertical error bars.
if option "4" is specified a smoothed filled area is drawn through
the end points of the vertical error bars.
Example:
{
gROOT->Reset();
c1 = new TCanvas("c1","A Simple GraphErrors Example",200,10,700,500);
const Int_t n = 20;
Double_t x[n], y[n], ex[n], ey[n];
for (Int_t i=0;i<n;i++) {
x[i] = i*0.1;
y[i] = 10*sin(x[i]+0.2);
ex[i] = 0.08;
ey[i] = 0.1*i;
}
gr = new TGraphErrors(n,x,y,ex,ey);
gr->Draw("A3");
}
