1.06-2

	[CHANGE] Conforms to jnum 0.20. 

	[CHANGE] Header edits no longer use Cursor, following jnum 0.20
	convention.

	[TWEAK] Suppress messages about trimmed header comments, and 
	duplicate header cards.



1.06-1


	[NEW] {imagetool} New option 'pxlcrop' that behaves like 'crop' but
	takes min/max pixel indices instead of angular offsets.

	[CHANGE] Extra header keys are now migrated from the master header
	of the input images.

	[CHANGE] Extra HDUs in input images are carried on without 
	modification.


1.05-7

	[TWEAK] Convert CRUSH images written in Jy/pixel to Jy/beam, when
	necessary.


1.05-6

	[BUG] {imagetool} 'imagetool' was broken due to a badly placed line of
	code. Fixed.

	[FIX] Autocrop vertical range determination was flawed. Fixed.

	[COSMETIC] Updated icon set.


1.05-5

	[FIX] Noise factor reported for image noise was actually squared.

	[TWEAK] Reporting source of noise estimate changed from 'data' and
	'image' to 'RAW' and 'IMAGE'.



1.05-4
	[FIX] 'brightness' offset in sqrt scale fixed. It does go negative 
	properly.

	[TWEAK] Finer 'brightness' and 'contrast' adjustment steps.


1.05-3

	[NEW] {imagetool} '-masks=xflag' option that allows flagging data 
	outside of the masked regions.

	[NEW] {imagetool} '-azimuthal' option to write azimuthal profiles of 
	circular regions.

	[FIX] {show} Occasional NullPointerException in 'Distance Measure' mode
	fixed.

1.05-2

	[TWEAK] Disable nom.tam.fits duplicate header key warnings (for now...)

1.05-1

	[NEW] {imagetool} Image operations now add HISTORY entries into the
	FITS headers.

	[NEW] {coadd} Coadding now adds HISTORY entries to FITS header.

	[FIX] Conversion to MJy/sr fixed. Previously it did not account for
	amoothing properly. See more below...

	[FIX] Image beam sizes (FWHM and area) are now calculated dynamically
	based on the underlying beam properties and smoothing. This provides
	a more robust approach, which is less prone to errors.
	

1.04-2

	[FIX] 'imagetool' '-masks=match' option was not working well with 
	generic mask inputs. Now it should be somewhat better...

1.04-1

	[NEW] 'imagetool' has a new option -flatNoise=X, which sets a flat 
	noise rms value of X for the entire image.

1.03-1
	
	[BUG] Errors on aperture fluxes have not been renormalized for smoothed
	images, yielding unrealistically low aperture flux errors when
	smoothing was used. Fixed.

	[FIX] Median levelling outside regions only! (Previously the entire
	map are was used.)

	[CODE] Math.hypot() replaced with faster (though less precise) 
	ExtraMath.hypot().


1.02-1

	[NEW] Support for newly introduced FITS keywords:

		SBMAJ, SBMIN, SBPA	// smoothing beam
		XBMAJ, XBMIN, XBPA	// extended filter beam
		IBMAJ, IBMIN, IBPA	// underlying instrument beam

	These are in standard units (e.g. radians if angles or standard SI 
	units otherwise).


1.01-4

	[BUG] Re-estimation of noise ran amok, causing major problems in
	the source extraction tool 'detect', for example. The bug was due to
	botched legacy support for old maps created by CRUSH-1.xx. It is
	hopefully fixed now, while still maintaining legacy support. 

	[FIX] Deconvolution normalization fixed.

	[FIX] {show} File->Reload did not reset menus as expected. Fixed.

1.01-3	

	[BUG] Equatorial (RA/DEC) image output had the wrong CDELT1 sign 
	(should have been negative, but was written positive). As such, maps
	produced by 'imagetool', 'coadd', 'difference', or 'detect' all 
	appeared inverted.


1.01-2 	(21 August 2014)	

	[FIX] Polygon display inadvertently broken in previous update. Fixed.


1.01-1	(6 August 2014)

	[NEW] {show} Distance measure mode is added. In that mode, dragging
        will measure distances between two points on the map. The measure mode
        can be toggled on/off in the Tools menu, or via the hotkey 'm'.


1.00

	--- Initial Release --- 

	[NEW] {show} Use arrows to reposition image in steps (or drag with 
	mouse [see below] for finer control).

	[NEW] {show} Pressing Control key (Ctrl) together with mouse button is
	the same a a right button press, while Alt+button is the same as a 
	middle button press. This makes things easier for the MacOS folks.

	[NEW] {show} GUI launches even when no image argument is given.

	[NEW] {show} Menus can now be used for many operations.

	[NEW] {show} Display images of all coordinates systems (e.g. Galactic
	Ecliptic, Super-Galactic or Focal-plane).

	[NEW] {show} Drag images around with right button pressed.

	[NEW] {show} Continuous repaints while dragging/zooming.	

	[NEW] {show} Circular regions and polygonal apertures repaint while
	drawing, always showing current size/shape.

	[NEW] {show} Center and circular radius are shown in info panel while
	drawing circular regions. Coordinates and offsets are show in Polygon
	Draw Mode.

	[NEW] {show} Polygonal regions are now also labelled.

	[NEW] {show} Mouse wheel can be used to zoom image in/out. On the flux
	labels it adjust zero level. While similar to pressing 'Z'/'z' or
	'B'/'b' the wheel action offers finer control.

	[NEW] {show} Window now has its proper CRUSH icon instead of the
	generic java one :-).

	[NEW] {show} Hotkey 'S' can be used to resample on a coarser grid. 
	(Note, 's' was already defined as resampling onto a finer grid, so it 
	was just a matter of offering the complement operation.)

	[NEW] {show} Hotkey 'D' can be used to delete the last circular region 
	only.

	[NEW] {show} Hotkey 'a' can be used to toggle between rendering speed 
	and quality. In 'speed' mode repainting while dragging is also 
	disabled, resulting in a similar funtion as before the new fancy 
	updated. Quality rendering is default. The command-line option 
	'-nofrills' can also be used to select 'speed' mode at launch.

	[SPEED] Eliminated unnecessary complex weight calculation when reading
	FITS. This resulted in a considerable speedup when opening large images.

	[SPEED] Small performance tweaks to FITS reading.

	[SPEED] {show} Accelerated rendering via BufferedImage().

	[SPEED] {show} Removed extraneous repaints().

	[SPEED] {show} Multithreaded rescaling calculation.

	[SPEED] {show} Reversed loops in most places for faster execution.

	[FIX] {show} Middle and Right mouse clicks now detected for MacOS.

	[FIX] {show} 'Temperature' colorscheme was added twice by mistake.

	[TWEAK] {show} Initial size of window is made to be a better fit to
	the desktop.

	[TWEAK] {show} Updated help screen.

	[TWEAK] {show} Fitting circular regions has cleaner output.

	[TWEAK] {show} Font changed from Monospaced to SansSerif on region and
	flux labels and info panel.

	[CODE] Eliminated duplicate utility classes. The tools now fully rely 
	on the kovacs.util classes.

	[CODE] {show} Eliminated SHARC-2 specific code bits and most dead code.
  
	[CODE] {show} Hotkey detection made more elegant.

	[MAN] Updated man pages.
