What's new in GRASS 5.0 beta4 against beta3? (Oct. 1999)

• Lots of bugfixes over 5.0beta3: e.g. fixed "empty text screen" problem, futher improved source code structure, new debug routine G_dump, added missing return statements...
• 121 projections supported now!
• Use m.proj as your "projection calculator" for all 121 projections
  
• DISPLAY: fixed: d.area, d.sites.qual, d.vect.cats
• updated/fixed: g.setproj, m.proj, both support the 121 projections
• RASTER: fixed: r.colors, r.digit, r.flow, r.resamp.rst, r.to.sites, r.slope.aspect, r.contour r.in.poly, r.statistics
• IMAGERY: fixed: i.rectify
• SITES: fixed instable sites format (concerns all site modules)
• fixed: s.surf.rst
• added several sites modules: s.normal, s.perturb, s.qcount, s.probplt, s.rand, s.sample, s.sv, s.univar, s.kcv
• VECTOR: fixed: general bug for all vector modules
• fixed: v.to.rast
• updated: v.in.shape: category text labels support now
• v.digspline renamed to v.digit, removed old v.digit stuff
• added several vector modules from GRASS 4.2.1: v.random, v.extract, v.merge, v.autocorr, v.info, v.export, v.geom
• NVIZ2.2: fixed map selection problem
  - "image dump" writes "xv" readable files now

• Still to do: update r.in.hdf to 4.1.3HDFlib, correct r.surf.contour
• detect further bugs (please report them! or fix them...)
• get vector format 64bit compliant (needs further input)

GRASS 5.x represents the first major change in GRASS GIS functionality in several years.

1. New formats:

2. new applications

3. Improved functionality:

4. New projections:

5. Misc:

      - gets() is an Achilles' heel for GRASS when used on the Web, or where
        through ignorance or malice someone can overrun an input buffer. I 
        have replaced gets() calls with the slightly safer fgets(). 
      - G_warning() and G_fatal_error() are called throughout the GRASS code
        tree as though they accepted variable arguments, i.e. 

           G_warning("Oops: error in %s, i = %d\n",string,integer);

        which is not how they were written. They were written to accept one
        char*, which they write to the screen and/or log. I have re-written 
        these functions so that they accept varargs. This change has not
        been approved by anyone, nor passed any peer review. It just seems 
        right. 
      - G_free() as as companion to G_malloc() and friends. It is annoying
        to have to replace all of the #include  with 
        #include  so instead I just created a function to be 
        included in the gis.h header. This is portable, which is an 
        improvement. 
    

      - It's much easier to track down the mismatched arguments and implicit
        casts with prototypes. These patches provide prototypes for all of
        the src/libes, and as many other libes and modules as I have gotten
        into. 
      - In the module code, the 4.2.1v21 patch has automatically-created
        header files to provide function prototypes within each module. Some 
        of this is overkill. As I work through each module, these headers
        are fixed to be a little less intrusive. Right now, though, there 
        are still compile warnings that are the fault of this prototyping.
      - The 5.0 code has not had as much work as the 4.2-series, so there
        are still a number of bad calls lurking in the modules. With the 
        proper prototypes, maybe somebody can fix them. 
    

     -  Functions with the wrong number of arguments. 
     -  Functions with the wrong type of arguments. 
     -  Functions with the wrong return type. Usually, this is because a
        function is allowed to default to an 'int' return, even though it 
        returns a char*, or struct*. This may work on 32-bit machines, but 
        whenever sizeof(char*) != sizeof(int) (64-bit machines, for example) 
        these functions overwrite memory, dump cores, and generally fail 
        to work. 
     -  Built-in functions without the proper headers. This leads to bad
        return types.
