Updates on open requirements
============================
 + See slides
 + #0401 Proposed for closure
 + #0402 Proposed for closure
 + #1202 Need to understand whether HARP wanted RGP specifically or whether
 they are satisfied with the present solution (Bertini/FTF)
 + #1504 Proposed for closure, but needs communication with Scott Messenger to
 find out whether 9.4 beta meets his requirements.
 + #1502 Prompt beta testers to give feed-back
 + #2501 CMS has performed tests and see no clear benefit.
 Contact CMS to understand whether the item can be closed. 

 Newest requests
 + #2701 charged Kaon cross-section = charged Kaon interaction cross-section 
 + #2703 Proposal to add header and trailer lines to error messages 
 OK with LHCb
 + #2704 Discussion postponed to the user presentation
 
Overview of 9.4-beta release and perspective of 9.4 release in December
=======================================================================
 + See slides
 + slide 7, bullet >>New fast precise neutron cross-section 
 Note: achieved using interpolation of the G4NDL cross sections.
 + slide 15, Bertini interface to precompound will probably not make it into
 the release

 Following the presentation, users were asked to comment on the list of 
 planned supported platforms.
 LHCb: would like to see Visual C++ 9.0 still supported 
 support for Mac OSX 32bit because it has a slightly different compiler
 ALICE: ok
 ATLAS, CMS: not present 

Users' presentations
====================
+ ALICE: Request for Anti Ion Transport (anti-proton to anti-helium)
 + See slides
 Also during the Space Users Workshop dbar support has been requested

+ Requirements on accurate neuron transport and low-energy hadronic physics
 + See slides
 - ENDF/G4NDL no alternative to NJOY (no conversion tool)
 - Tool involved is based on NJOY. NJOY itself is distributed by RSICC.

+ Refined requirements on PIXE
 + See slides
 - To slide 1
 > Have used diagrams to create header files, and tested these for compilation
 and compatibility tests. The evaluation's conclusions are being prepared.
 Results will be reported as soon as available.
