     ==================================================================
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.
