Xming X Server for Windows

Changes for Xming version 7.5.0.79 (Snapshots: x86 & x64 22 Apr 2014 13:58)

Update FreeType2 from its project git repository, and the xserver, libXfont, Mesa, pixman and xkeyboard-config from X.Org git.
Use an 8 point font for the 'About Xming' dialog links instead of a fixed height font in logical units. Stops the Website Links being inconsistent with the version and copyright text.
Add customised Windows 8.1 Start screen tiles for Xming and XLaunch.
Stop reporting GL extensions which are supported by WGL but not by the X server (thanks to Jon Turney).
libXfont is now supplied as a dll (thanks to Yaakov Selkowitz). This libraries weak symbol use had prevented correct run-time linking, on PE platforms, and so it had to be linked static.
Because of the awfully tall title bar and the lack of obvious built-in help, in the Aero-style version of XLaunch: I've reverted to just supplying XLaunch in traditional Wizard97 style.
Remove the website link icon from the Start menu (it just clutters the Xming entry in Windows 8.1 Apps view).
Update the OpenGL extension headers and specifications from the canonical OpenGL Registry for use in the X server build (Khronos SVN at revision 26326).
Build both Plink(s) from PuTTY project SVN source at revision 10181.
Xming 7.5.0.78 (Released 11 Apr 2014).

Future and features

I've tested using MinGW-w64's winpthreads as a replacement for Pthreads-Win32 (which is still an active project) and have not yet found a good reason to switch e.g. mutexes appear to be slower and C++11 support isn't needed.
XLaunch's XPing and -find don't work yet with IPv6. Plus testing of XDMCP on IPv6 networks has not been very extensive
Fix a 'borders black, corrupted or missing' rendering error in -mwextwm mode e.g. with xcalc and oclock (tricky). An API change (13/9/07 'Remove the PaintWindow optimization') seems to be the cause.
Get -pseudocolor to work with the various engines (I need an antique 8-bit colour Unix system to progress this). As a workaround use -fullscreen at -depth 8.
Fully utilize the MPX code so that multiple mice and keyboards work with the X server (the MPX code is currently forced/bypassed to be single mouse/keyboard).

Xming-portablePuTTY 7.5.0.79 (x86 & x64 Released 21 Apr 2014)

Build from PuTTY project SVN source at revision 10181.
Make the default 'Preferred SSH protocol version:' 2 only in PuTTY. SSH version 1 is no longer considered safe and the selection '2 only' can be easily changed if you must use it.
Add customised Windows 8.1 Start screen tiles for Pageant, PSFTP, PuTTY and PuTTYgen (but not promptless console applications Plink and PSCP).
Remove the website link icon from the Start menu (it just clutters the Portable PuTTY entry in Windows 8.1 Apps view).
Xming-portablePuTTY 7.5.0.78 (Released 11 Apr 2014).

Xming 7.5.0.78 (x86 & x64 Released 11 Apr 2014)

Update FreeType2 from its project git repository, and the xserver, libX11, libxcb, libXext, libXpm, Mesa, pixman, xkbcomp and xrandr from X.Org git.
Review and sanitise some -logverbose 3 messages from the server.
Tidy and sanitise some of the clipboard code; including making use of Windows global clipboard memory safer.
Provide an explicit error report when the clipboard selection data is empty and don't try to convert nothing!
Widen the 'About Xming' dialog to prevent a text wrap on Windows 8.
Work-around problems when using Xlib client macros in the server in a 64-bit build. (thanks to Jon Turney)
Improve mapping of the no-decoration MOTIF hint to remove system menu controls. (thanks to Jon Turney)
Remove decorations and system menu controls from _NET_WM_WINDOW_TYPE_SPLASH type windows. (thanks to Jon Turney)
When running XLaunch, with 'Display number' empty (i.e. being set automatically), dynamically override any fixed X-Forwarding 'X display location' setting in Plink. Also match XLaunch's display setting with that of the X server, when IPv6 is enabled, to fix a %DISPLAY% mismatch between Plink and the X server.
In xclipboard the default file could not be saved to the install directory. Make this default 'clipboard.txt' on the Windows Desktop (%USERPROFILE%\Desktop\), and when %USERPROFILE% is unset, 'clipboard.txt' in the first available path from GetTempPath().
Update the OpenGL extension headers and specifications from the canonical OpenGL Registry for use in the X server build (Khronos SVN at revision 26208).
Build both Plink(s) from PuTTY project SVN source at revision 10161.

Update FreeType2 from its project git repository, and the xserver, libX11, libxcb-icccm, Mesa, xev, xkeyboard-config and xrandr from X.Org git.
In Xmon fix unknown GenericEvent type decoding. Transposed parameters meant that it was printing the sequence number rather than the type. (thanks to Daniel Stone)
In XLaunch no longer terminate the server when the first client exits. This was a weak feature of the original design which no longer makes sense.
Ensure alpha characters or spaces can't get into the 'Display number' field of XLaunch when loading badly edited (or unvalidated) .xlaunch files.
The version-information resource had gone missing from libxcb-icccm.
Update the OpenGL extension headers and specifications from the canonical OpenGL Registry for use in the X server build (Khronos SVN at revision 25681).
Build both Plink(s) from PuTTY project SVN source at revision 10156.

Update FreeType2 from its project git repository, and the xserver, glxgears, glxinfo, libX11, libxcb, libxcb-icccm, libXext, libXfont, Mesa and xkeyboard-config from X.Org git.
Don't create fbConfigs for un-accelerated pixelFormats provided by the generic renderer. (thanks to Jon Turney)
Allow the Windows beep/bell to be turned off with generic X server option -f 0, or when the server is running, by xset -b or xset b off or xset b 0. Unlike the X server on Linux/Unix, no fine control of volume, pitch or duration is possible due to the use of the MessageBeep(MB_OK) function i.e. just the Windows default beep.
Correctly free the buffer object data with _mesa_align_free(bufObj->Data) in _mesa_delete_buffer_object(). Note: release 7.5.0.74 did not have this problem and it is now fixed in X.Org git master Mesa.
Tidy some comments in the XLaunch XML Schema Definition file.
Update the OpenGL extension headers and specifications from the canonical OpenGL Registry for use in the X server build (Khronos SVN at revision 25148).
Build both Plink(s) from PuTTY project SVN source at revision 10135.

Revert X.Org xserver change 'glx: Simplify glXDestroyContext'. You get BadContextTag errors when the tag for a deleted context is given as the previous tag in a MakeContextCurrent request (thanks to Jon Turney for spotting this).
Revert X.Org xserver change 'glx: Fix a corner case in DrawableGone'. You can get an xserver crash, on client exit, if this is not reverted with the above.
Make WGL child window creation more consistent with its parent.
Add Windows XP x64 Edition to the OS detector.
Don't use xserver/hw/xwin/ddraw.h in the build: it's not consistent with ddraw.h from MinGW-w64 (i.e. DirectDraw2 methods are equivalent between MinGW-w64 and Microsoft, but not the local ddraw.h)). Also fix two 'incompatible pointer type' build warnings when including MinGW-w64's ddraw.h and calling the IDirectDraw2::CreateSurface method.
Update the OpenGL extension headers and specifications from the canonical OpenGL Registry for use in the X server build (Khronos SVN at revision 24702).
Build both Plink(s) from PuTTY project SVN source at revision 10109. The change since the last release is only a minor one (from Simon Tatham), I had already similarly patched, so there is no functional change.

Tidy some clipboard patches for the xserver.
Sanitise the installers' Welcome page.
In the Xming installer promote Xmingrc and libXfixes to main components from tools. Also, no longer supply the obsolete example_Xmingrc file with tools components.

Migration to the MinGW-w64 toolchain is now complete (currently: gcc release 4.8.1, binutils CVS head 2013-07-22 and mingw-w64 trunk SVN 5982).
Provide an x64 Xming (i.e. built native 64-bit for Windows x64) in parallel with the original 32-bit version.
Fix various taskbar quirks (and others) in -multiwindow mode (x64 Xming). Some calls to XChangeProperty() and XGetWindowProperty() needed correcting for the increase in size of a HWND (from one to two 32-bit quantities) between x86 and x64.
Fix the WoW detector log report and add x64 Xming detection.
In -multiwindow mode more closely follow ICCCM section 4.1.7 when setting X input focus to a window when the native Windows window acquires input focus. This helps JDK 1.7 clients acquire the focus correctly. (thanks to Jon Turney)
No longer ship libXaw-6.dll, it is obsolete, only libXaw-7.dll is linked by 'Tools and clients'.
Correct four functions with 'unsigned long' parameters (declared in xserver/hw/xwin/winprefs.h) where just a specific handle type should have been used (fixes some x64 build warnings).
Htmlhelp.lib is now linked x86 and x64, by XLaunch and portablePuTTY, from the Windows Software Development Kit (SDK) for Windows 8. Note: these 'Static LIB files' are classified as Distributable Code by Microsoft in their SDK license.

Supply XLaunch built with MinGW-w64 (for x86); again! The wide-character function quirks, with the new toolchain (currently: gcc release 4.8.1, binutils CVS head 2013-07-05 and mingw-w64 trunk SVN 5935), are finally fixed and migration to it can therefore continue (x86 and x64).
Migrate libxcb's build to the new toolchain and correct a missing closesocket() call on an error path. Also migrate bitmap, ico, libICE, libSM, libXaw, libxcb-icccm, libXext, libXfixes, libXi, libXmu, libXrandr, libXrender, libXt, libXtst, mkfontscale, oclock, viewres, xcalc, xclock, xhost, xkbcomp, xkill, xlsatoms, xlsclients, xlsfonts, xmodmap, xprop, xrandr, xset, xsetroot and xwininfo.
