    1. The following platform specific bug on HPUX has been fixed:
      Dear Oz'ers,
      I tried to browse the line
         {System.virtualStringToValue "a([1.0 3] "#'f:(a#(b(4 unit)#c#_)))'}  
      from chapter 6.4 of the Users Manual with Oz-2.0.4, running under
      HP-UX-9.0 and I got the error message:
      
       %************ parse error **********
       %**
       %**     expecting `LDOTS' or `')''
       %**     in line 1, column 20
       %**
       *** ********************************************************
       *** Error: System
       *** 
       *** illegal argument to System.virtualStringToValue
       *** Virtual String: a([1.0 3] f:(a#(b(4 unit)#c#_)))
       *** 
       *** CallStack: 
       *** procedure SystemVirtualStringToValue ( File: ././System.oz Line:
      108 PC: 1075646168 )
       *** procedure Toplevel abstraction ( Line: 0 PC: 1075431208 )
       *** --------------------------------------------------------
      
      However, doing the same with Oz-2.0.4 under Windows95 works fine.
      Does System.virtualStringToValue need special access to Operating 
      System  functionality, e.g. for creating temporary files?
      Any Idea ?
      

    2. The documentation for Search.object was inconsistent. The method close does not exist, the right method to use is clear (documentation has been fixed).

    3. If the FTP server ftp.ps.uni-sb.de does not work, the system files of the Oz distribution can be also downloaded with the HTTP protocol from http://www.ps.uni-sb.de/oz2/system/dist/.

    4. Emacs 20 requires a patch, which is also included in the lastest distribution.
