Hi all,

I've released a new version of octave-forge.  The
main change is that oct-file support has been
extended backward to octave-2.1.36, plus there is
the usual mix of bug fixes and new functions.
Get it from http://octave.sf.net.

* Extended support backward to octave 2.1.36 and forward to octave 2.1.49
  for all oct-files.  Some scripts make use of features only available in
  more recent versions of Octave.

* Communications: 
  - sqrt over Galois field
  - BCH code, modulator
  - bug fixes and documentation improvements

* Image:
  - added rotate_scale() 

* Optimization:
  - added Nick Higham's adsmax, mdsmax nmsmax for fmins
  - lp() fix range error

* Plotting:
  - surf()/surfc() support gnuplot 3.8i shaded surfaces
  - added peaks()
  - legend() inside/ouside/boxon/boxoff/right/left

ignal Processing 
  - added freqs, invfreqs, invfreqz
  - return statespace and laplacian IIR filters (butter, cheby1, cheby2, ellip)
  - fixed aryule() to return the correct filter

* Statistics: 
  - added normplot()
  - scatter() optimization

* Sparse:
  - added concatenation functions spvcat() and sphcat()

* Symbolic: 
  - added poly2sym, sym2poly, numden, findsymbols, findsym, symlsolve, 
    symfsolve, syminfo
  - subs() accepts cell arrays

* TSA/NaN:
  - many bug fixes and documentation improvements

* Miscellaneous:
  - added cellstr()
  - fieldnames() now returns cell array
  - listen() bugfixes
  - ellipke() supports m < 0
  - deal() now supports [a,b] = deal(b,a)
  - dlmread() converted to C++ for speed and more flexible input

* administration: 
  - target specific build instructions (MacOSX, windows, Irix)
