		Dear Go4 users, 
 
the new Go4 version 2.8-0 (build 20800) is available now! 
 
Inside gsi, you can select this version by 
        ". go4login pro" or just ". go4login" 
This command selects Go4 version 2.8-0 with ROOT 4.00/08 
and Qt 3.1.1. A rebuild of the user analysis (make clean all) is necessary.  
 
Go4 versions available by ". go4login xxx" are now: 
"new"           = v2.8-0 (ROOT 4.00/08, Qt 3.1.1. , with future bugfixes) 
"pro"           = v2.8-0 (ROOT 4.00/08, Qt 3.1.1. , from release tarball)  
"old"           = v2.7-0 (ROOT 4.00/04, Qt 3.1.1.) 
Please see ". go4login -h" for complete list. 
 
 
For installation outside gsi linux cluster, 
the complete Go4 framework v2.8 is downloadable as tarball  
at the Go4 website http://go4.gsi.de.

New features in Go4 v2.8 (Sep04) 
 
1.	Marker editor in view panel allows for marking  
	channels or windows.  Labels and arrows can be created. All  
	marker elements can be saved/restored. 
 
2.	New ROOT graphical editor can be called from view panel.  
	The editor dynamically adjusts to the graphical object  
	selected by LMB. 
 
3.	Viewpanel window title: can optionally be set by user and  
	may be kept constant. If a TGo4Picture is displayed, the  
	picture name defines the viewpanel title. 
 
4.	Condition editor: the cursor mode has been removed because the 
	functionality is now provided by the markers 
 
5.	Condition, markers and labels: Implemented correct root  
	streamer (bugfix), i.e. saving and loading these objects  
	in root files is possible with fully recovered functionality 
	and graphical properties. Support of pad display in  
	lin/log scale (bugfix). Additional controls in RMB menu  
	root (set ranges, location, save default properties, 
	reset). Default label setup stored with go4 GUI settings. 
	 
6.	Polygon condition: Implemented statistics functions for  
	work histogram under the cut (integral, mean, rms, etc.).  
	Enabled "InsertPoint/RemovePoint" function in RMB menu (bugfix). 
 
7.	Fit GUI: Selection between sigma and FWHM (default) by  
	Settings->Recalculate gauss width. Fit results may be  
	printed to terminal or Go4 logfile output. 
 
8.	1D drawing: ROOT "L" (line) "C" (curve) "B" (bar chart)  
	"P0" (poly-marker) line styles supported. 
 
9.	Histograms: re-binning, projections, and profiles  
	supported (standard ROOT methods with RMB). Automatic  
	"synchronize with memory" on pad click to get newly  
	 created histograms. 
 
10.	Histogram client: monitoring implemented (auto-update).  
	Drag and drop support. Display error message when server  
	connection is not available (bugfix). Store server  
	specification in Go4 settings. 
 
11.	File store: Storing objects into a ROOT file a title is 
	prompted. This title can be seen in the Go4 browser and  
	the ROOT browser. 
 
12.	UserObjects folder: With AddObject(...) histograms,  
	parameters	and conditions can be put into folders of the 
 	UserObjects folder. They can be located there by the  
 	standard Get methods, e.g. GetHistogram. Editors work also  
 	with objects in these folders. Note: object names must  
 	be unique! 
 
13.	Log window: Empty messages are now suppressed (bug fix). 
 
14.	QtROOT interface: bug fix concerning initialization  
	order of X11 system (ROOT init now before Qt init).  
	Lead to crash of the main gui on newer linux systems  
	when using Qt versions > 3.1 (FEDORA2, SuSe9.1)  
 
15.	Thread manager: bug fix: adjusted default exception  
	handling to work with newer libpthread.so that uses  
	one process for all threads (e.g. FEDORA2). This lead  
	to a crash when go4 threads were canceled 
	(shutdown of the go4 GUI). 
 
16.	Analysis Framework: bug fix: analysis without analysis  
	step (UserEventFunc only) again possible. 
 
17.	Client startup script: full PATH and LD_LIBRARY_PATH   
	of the Go4 GUI environment is passed to the  
	analysis process.
