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.

From Valeriy Onuchin:
Changes in font handling connected with html widget development and allows to find the best matching font specified by family, point size, weight, slant. They include:
- new structure describing font attributes
struct FontAttributes_t {
const char *fFamily; // Font family. The most important field.
Int_t fPointsize; // Pointsize of font, 0 for default size,
// or negative number meaning pixel size.
Int_t fWeight; // Weight flag
Int_t fSlant; // Slant flag
Int_t fUnderline; // Non-zero for underline font.
Int_t fOverstrike; // Non-zero for overstrike font.
};
- new class TGTextLayout is used to keep track of string
measurement information.
- new TGFont methods (see descriptions in the source):
Int_t TextWidth(const char *string, Int_t numChars = -1) const;
Int_t XTextWidth(const char *string, Int_t numChars = -1) const;
Int_t TextHeight() const { return fFM.fLinespace; }
void UnderlineChars(Drawable_t dst, GContext_t gc,
const char *string, Int_t x, Int_t y,
Int_t firstChar, Int_t lastChar) const;
TGTextLayout *ComputeTextLayout(const char *string, Int_t numChars,
Int_t wrapLength, Int_t justify,
Int_t flags, UInt_t *width,
UInt_t *height) const;
Int_t MeasureChars(const char *source, Int_t numChars, Int_t maxLength,
Int_t flags, Int_t *length) const;
void DrawCharsExp(Drawable_t dst, GContext_t gc, const char *source,
Int_t numChars, Int_t x, Int_t y) const;
void DrawChars(Drawable_t dst, GContext_t gc, const char *source,
Int_t numChars, Int_t x, Int_t y) const;

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 Federico Carminati:
"I have implemented all copy and equal operators needed to silence all
warnings in AliRoot, as requested. I have implemented shallow copies as
would do the default operators synthetized by the compiler.
Most operators are protected. If users complain, you just have to move
them into the public area, but class derivation is of course supported.
It has been a terrible job, I have modified 278 files, but the changes
are backward compabile, and this goes a long way to permitting user to
use the effc++ flag with root headers."

From Ilka:
Any ROOT GUI can now be saved as a macro. Executing this macro brings back
the current GUI (minus the action handling). This very important development
allows to get easily the source for any GUI, which can then be inspected or
used to create other GUI's. Also this will allow a GUI builder to save and
restore GUI's.
To save the source of a GUI use the methods TGMainFrame::SaveSource() or
TGTransientFrame::SaveSource(), where the latter saves the source for dialogs.
To trigger the saving of any GUI just use ctrl-s.

major changes in the resource management of the GUI classes. Introduced the
new class TGResourcePool which loads and keeps track of the 3 main resource
pools: fonts, picture and graphics contexts. Fonts are now handled via the
new TGFont class (and TGFontPool). In the past the loading of these resources
was done in TGClient and required all GUI classes to have TGClient as friend
to have their global statics initialized by TGClient. Adding a new widget
required TGClient.cxx to be changed too. This was obviously not good.
In addition it is now possible to find the full definition of the original
resource back based on a resource handle (GContext_t or FontStruct_t yielding
a TGGC or TGFont) which is needed for the SavePrimitive() functionality.
The resource pool can be found via TGClient (e.g. gClient->GetResourcePool()).
To see all active graphics contexts, fonts and pictures do:
gClient->GetResourcePool()->GetGCPool()->Print()
gClient->GetResourcePool()->GetFontPool()->Print()
gClient->GetResourcePool()->GetPicturePool()->Print()
For more examples see the widget source code.
These changes are largely backward compatible except maybe for some low
level 3rd party widgets that use some TGFrame internals. In these cases
the following sed command will patch the code:
sed -e "s/fgBlackGC()/GetBlackGC()()/g" \
-e "s/fgWhiteGC()/GetWhiteGC()()/g" \
-e "s/fgHilightGC()/GetHilightGC()()/g" \
-e "s/fgShadowGC()/GetShadowGC()()/g" \
-e "s/fgBckgndGC()/GetBckgndGC()()/g" \
widget.cxx > widget.cxx.new
