5 new predefined palettes with 255 colors are available vis SetPalette:
if ncolors = 51 and colors=0, a Deep Sea palette is used.
if ncolors = 52 and colors=0, a Grey Scale palette is used.
if ncolors = 53 and colors=0, a Dark Body Radiator palette is used.
if ncolors = 54 and colors=0, a two-color hue palette palette is used.(dark blue through neutral gray to bright yellow)
if ncolors = 55 and colors=0, a Rain Bow palette is used.

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.

TPad::Print always use TImageDump to print gif, png and jpeg files, in interactive and batch mode (previously it was used in the batch case only). This allows to generate output transparent colors in these formats even in interactive mode. The generation of gif, png and jpeg files from the graphics window in interactive mode is kept for OpenGL canvases.

- AsHexString was not returning the proper value in case
of "IsGrayscale()". Before this change gray scale mode

- In TColor::InitializeColors() SetPalette is called only if fgPalette.fN == 0.
fgPalette.fN !=0 means that SetPalette has been, very likely, already called
from rootlogon.C. Calling it again would reset the palette.

Implement two new static functions in TColor
Int_t TColor::GetColorBright(Int_t n)
// Static function: Returns the bright color number corresponding to n
// If the TColor object does not exist, it is created.
// The convention is that the bright color nb = n+150
Int_t TColor::GetColorDark(Int_t n)
// Static function: Returns the dark color number corresponding to n
// If the TColor object does not exist, it is created.
// The convention is that the dark color nd = n+100

TMath::Abs, TMath::Min, TMath::Max, TMath::Sign, TMath::Range
These functions are unfortunately not defined in a standard way in std::
This include is referenced by a new version of TMath.h.
As a result, TMath.h is back compatible with the previous version.
TMathBase.h is used in place of TMath.h in all the classes
that will go into the future miniCore library.
TMath.h and the TMath implementation will go into a new math sub-directory.
TString.h uses TMathBase.h instead of TMath.h.
As a result, it was necessary to include "TMath.h" in some classes
assuming that TMath was included via TString and using other functions
than the ones defined in TMathBase.h

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 Axel:
Patch to set a canvas in grayscale mode (default is color).
New functions in TCanvas and TColor
void TCanvas::SetGrayscale(Bool_t set /*= kTRUE*/)
Set whether this canvas should be painted in grayscale, and re-paint
it if necessary.
One can toggle between a grayscale preview and the regular
colored mode using TColor::SetGrayscale(). Note that in grayscale mode,
access via RGB will return grayscale values according to ITU
standards (and close to b&w printer grayscales), while access via
HLS returns de-saturated grayscales.
TCanvas::SetGrayScale is available via the TCanvas context menu.

From Valeriy Onuchin:
- massive update of TImage/TASImage class.
- update rose_image.C macro to demonstrate new features.
- new example hist2image.C added
I'll try to add more example and documentation asap.
- bug fixes in ROOT gui builder

From Ilka:
code for saving any user
specified color via color widgets in a macro. Any color different from
the standard root colors is saved via hex rgb string. Up to now colors
were save via the index and if this index > 228 the running macro causes
SegV.
A new static method SaveColor() is added in TColor class.

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.

new method GetPixel() and static method Number2Pixel(). Use these methods
to get the pixel value associated with the TColor. This pixel value can
be directly used in the TGxxx GUI classes. For example:
TCanvas *c = new TCanvas;
widget->ChangeBackground(TColor::Number2Pixel(c->GetFillColor()));

added three new static methods:
TColor::GetColor(Int_t r, Int_t g, Int_t b) with r,g,b in range [0,255]
TColor::GetColor(Float_t r, Float_t g, Float_t b) with r,g,b in range [0,1]
TColor::GetColor(const char *hexcolor) with hexcolor of form "#rrggbb"
these methods try to find the color with the specified rgb value in the
list of existing colors, if the color does not exist it will create a
new TColor with the name "#rrggbb", add it to the global list of colors
and return the color number.
Also made the methods HLStoRGB() and RGBtoHLS() static.

delay the calling of XAllocColor() for systems with >8 planes, also optimize
the number of times XAllocColor() is called for the _dark and _light colors.
XAllocColor() is very expensive since it waits for an answer from the X server
before returning. This optimization reduces the startup time of root.exe from
30sec to 10sec over a 64Kbps ISDN line.

W A R N I N G !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
==================================================================
A very long list of changes in this pre-release of version 3.00.
We have modified the signature of many functions (in particular TObject)
to introduce more constness in the system.
You must change your code if your class derives from TObject and uses
one of the modified functions such as ls, Print, Compare, Hash, etc.
The modified functions in TObject have the following signature:
virtual TObject *Clone() const;
virtual Int_t Compare(const TObject *obj) const;
virtual void Delete(Option_t *option=""); // *MENU*
virtual void DrawClass() const; // *MENU*
virtual void DrawClone(Option_t *option="") const; // *MENU*
virtual void Dump() const; // *MENU*
virtual TObject *FindObject(const TObject *obj) const;
virtual char *GetObjectInfo(Int_t px, Int_t py) const;
virtual ULong_t Hash() const;
virtual void Inspect() const; // *MENU*
virtual Bool_t IsEqual(const TObject *obj) const;
virtual void ls(Option_t *option="") const;
virtual void Print(Option_t *option="") const;
A similar operation has been done with classes such as TH1, TVirtualPad,
TTree, etc.
This form allows you to request diffs between any two revisions of this file.
