    "higher.." to "Godunov" (bug #6 fixed)
[!] Input Dialog provided no data validation for three integer step numbers
    (bug #5 fixed)
[!] Tool Sigma often crashed on [Apply] or [Update] (bug #7 fixed)
[!] Repaired [Ctrl+Shift+S] shortcut for Sigma tool (bug #8 fixed)
[#] String resources eliminated (preparation for internationalization - i18n)
[+] National language support in GUI (limited now to 8-bit encodings only,
    and only for German, French, Italian, Russian and Spanish for this version)

[+] Descriptive explanations of the purpose of menu items
    appearing in the status bar
[!] Project [dir]names can contain spaces from now (bug #4 fixed)
[+] Page "doc\glossary.htm"
[+] Install/uninstall support, changed version number to 0.96
[+] Images next to menu items in main menu
[+] Tool 'Sigma' (experimental) for editing tabular pressure loss
    (and other {x, y}) data and interpolating data by cubic splines
[+] Page "doc\tools.htm" to document tool 'Sigma'
[+] Project "prj\sigma" as a place to start testing tool 'Sigma'
[*] Input data dialog: tab order and checkboxes that can disable text fields

===============================
Version 0.95 Build Jan 01, 2005
-------------------------------
[*] InputDlg: size changed to fit within 800x600 display
[*] UI menus made closer to "Horsepower Lab 1D" standards
[*] Eliminated "\cfg\hpl2d.cfg" and "\cfg\postp.cfg": settings are now
    saved to the Registry
[+] "Open recent.." menu item to "Project" menu
[*] Eliminated "\prj\cprg": now using Reqistry instead
[*#]Changed naming convention for the package's distributive
    ZIP files: now it will look like "hpl2d.095-20050131.zip"
[*] Eliminated "\cfg\mesh.cfg" and "\cfg\" directory itself: 
    internal arrays are now being adjusted via dynamic memory re-allocation
[*] Improved error mesages issued by "mesh.exe"
[*] Debugged and tested the example projects

===============================
Version 0.95 Build Nov 06, 2004
-------------------------------
[+] Added files: README.TXT, LICENSE.TXT, FILE_ID.DIZ,
    CHANGES.TXT (this file), BUGS.TXT and TODO.TXT 
[#] Switched to packaging scheme similar to that of "Horsepower Lab 1D"
[#] Made "*.htm" files format closer to "Horsepower Lab 1D" standards
[*] Spellchecked "*.htm" files and validated them against W3C specs.
[!] Solver "hpl2ds.exe": crashed for severe supersonic flow regimes,
    for domains of specific types (bug #1 FIXED: introduced safer (slower)
    Riemann solver of Godunov instead of too approximate Lcs2 solver).
[!] Solver: failed to resume simulation smoothly: restoring flow data
    from disk was broken (bug #2 FIXED)
[*] Replaced the exact Riemann solver of Godunov by the approximate
    Roe's solver: speedup of up to 10 times achieved; no stability
    prblems detected
