GNU Astronomy Utilities NEWS -*- outline -*-
+* Noteworthy changes in release 0.1.XXX (2016-09-23) [alpha] Until commit
af59e45: Replaced all occurances of utility to program in book.
+** Bug fixes
+ Linker errors on some operating systems have been fixed (bug #48076).
+ Several memory allocation, checks or redundancies have been fixed: bugs
+ #48453, #48516, #48603, #48611, #48571, #48650, #48657, #48692, #48770,
+ #47866, #48899, #49049, #49007.
+ ImageCrop no longer crashes with very long output file names (bugs #46241
+ and #45380).
+** New programs or headers
+ Table: a new utility to read and write FITS binary and ASCII tables. It
+ can also print the column information (task #13579).
+ Shared libraries and headers are now installed. The libraries can be used
+ in C and C++ programs. This release includes the following headers:
+ `gnuastro.h', `array.h', `box.h', `fits.h', `linkedlist.h', `mesh.h',
+ `polygon.h', `qsort.h', `spatialconvolve.h', `statistics.h', `threads.h',
+ `wcs.h', `txtarray.h' (task #13765).
+ Gnuastro now comes with a script in its top source directory to configure
+ and build Gnuastro (or any other program using the GNU build system) in
+ the tmpfs (on the RAM) for those systems that have it. See the new
+ "Configure and build in RAM" section in the book for more (task #14100).
+** New features
+ MakeProfiles also accepts WCS positions (task #13566).
+ Flat profiles in MakeProfiles can be given a profile specific value. The
+ new `--mforflatpix' option MakeProfile will use the value in the
+ magnitude column as a fixed value for each pixel. This can be very useful
+ in defining a mask, or creating segmentation maps or labeled images (task
+ MakeProfiles can now use input image as canvas. Instead of specifying the
+ WSC and image size paramteres manually, with the new `--inputascanvas'
+ option, MakeProfiles will get this information (along with blank pixels)
+ from an already existing image (task #14116).
+ Type of output in MakeProfiles and Arithmetic can be specified with the
+ `--type' option.
+ Magnitude error column in MakeCatalog with the `--magnitudeerr' option.
+ Arithmetic now has new conditional (task #13870) and logical operators
+ (task #14153) along with an operator for actions only when conditions are
+ true: `where'. The new `isblank' operator will also enable you to select
+ blank, or masked, pixels (task #14146).
+ The `--noerodequant' in NoiseChisel enables it to detect more sharper
+ profiles by disabling erosion on pixels above a certain quantile (task
+** Changes in behavior
+ The two MakeProfiles options `--setconsttonan', `--setconsttomin' have
+ been removed (see `--mforflatpix' above for their alternative).
+ MakeCatalog makes clump catalog only when asked (when the `WCLUMPS'
+ header exists in the objects HDU). This can be very useful in cases like
+ aperture photometry, when the object labels are not generated by
+ NoiseChisel and so a clump image doesn't exist (task #14122).
