	* lib/: converted from statical to dynamical linked library
	* lib/: read_write_image and read_write_pivdata in single module io.c
	* lib/: all relevant functions for image PROCESSING and evaluation, 
	data-validation and post-processing have been included in the modules
	image.c eval.c, valid.c post.c of libgpiv
	* lib/: assert for checking on (non-)memory allocs in public functions
	* lib/eval.c: central differential scheme for image evaluation
	* lib/valid.c: substitution with particle displacement from next
	higher correlation peak by using the library function instead of
	rr.
	* lib/utils.c: gpiv_piv_gnuplot included.
	* lib/io.c: gpiv_fread_hdf_piv gpiv_fwrite_hdf_piv.
	
	* include/gpiv.h: reduced to main definitions, structure defs and 
	inclusions of headers under gpiv/
	* include/gpiv/: added image.h eval.h, valid.h post.h

2003-5-21 Gerber Van der Graaf
	* lib/io.c: HDF version 5 added
	* lib/: Spatial-scale, time-scale and zero-off_x/y parameters 
	moved from PivPostPar to ImagePar

2003-7-13 Gerber Van der Graaf
	* src/: libgpiv functions with error handling return 
	char *error_message = NULL or char *error_message != NULL
	* debian/: Binary packages can be extracted in Debian format.

2004-1-30 Gerber Van der Graaf
	renamed nbits to depth in ImagePar struct
	added image processing module img_proc
	tmp directory defined by TMPDIR, TMP or TEMP or /tmp is used

2004-2-18 Gerber Van der Graaf
	moved gpivrc to the more common name gpiv.conf
	process parameters use defaults if gpiv.conf is absent

2004-5-28 Gerber Van der Graaf
	glib used for memory allocation of vectors and arrays
	arrays and vectors with specified starting index ended with: _index

2005-1-19 Gerber Van der Graaf
	Initiation of Data Acquisition (DAC); trigerring of lasers and camera 
	by using RTAI and Realtime Linux. Obtained from J. Soria. 
	Recording images from IEEE1394 (Firewire) IIDC compliant camera's

2005-2-23 Gerber Van der Graaf
	improved adaptive grid by (bi)linear interpolation or substitution
	from old grid, gpiv_piv_select_int_point depreciated: substituted
	by gpiv_piv_gridgen.

2005-2-26 Gerber Van der Graaf
	added gpiv_piv_isiadapt, parameter flags (parameter_logic) defined as
	gboolean

== CD 0.3.0, Challenge
2005-5-20 Gerber Van der Graaf
	* lib/eval.c: improved int_mean: local image intensities
	* lib/eval.c: cov_top: improved snr, removed writing results to piv_data
	* lib/eval.c: cov_subtop: avoid division by 0
	* lib/eval.c: cova: removed char **fftwis; not needed as wisdom is public
	and causes memory leak
	* lib/eval_speed.c: optimized and simplified of internal function of
	dxdy_at_new_grid
== Sourceforge 0.3.2
2005-10-10 Gerber Van der Graaf
	* include/gpiv/: img_proc.h moved to imgproc.h
	* lib/: img_proc.c moved to imgproc.c
	* lib/: added imgproc_deform.c Provided by P. Thvenaz 
	(philippe.thevenaz@epfl.ch) and based on:
	P. Thvenaz, T. Blu, M. Unser, "Interpolation Revisited," IEEE  
	Transactions on Medical Imaging, vol. 19, no. 7, pp. 739-758, 
	July 2000.

== patch1 0.3.2
2006-24-2 Gerber Van der Graaf
	* src/img_proc.c: imgdeform; bug repair by Sjaak Verdoold
	<sverdoold@gmail.com> ; Height = image_par->nrows
	* src/eval.c: assign_img2intarr*; bug repairs by Sjaak
	Verdoold <sverdoold@gmail.com> ; Check if Interrogation Areas are
	within the image boundaries.

== patch2 0.3.2
2006-26-3 Gerber Van der Graaf
	* configure.in: library linked to libglib-2.0 instead of libglib-1.2
	* changed macro GPIV_CFLAGS/LIBS to GLIB_CFLAGS/LIBS
