# 2020-06-13: Version 0.9.13
0.9.13 truly is a cross-platform release, the best we've ever done in that respect:
Out of the [49 issues](https://github.com/LibVNC/libvncserver/issues?q=is%3Aclosed+milestone%3A%22Release+0.9.13%22)
closed with this release, 20 alone were related to MS Windows. The result is that 0.9.13
is the first release with full support for Microsoft Windows! The cross-platform focused
work did not end there tough: MacOS support was brought up from barebones to a fully working
production-grade VNC server application. Other highlights are improvements regarding TLS
in LibVNCClient, [SetDesktopSize](https://github.com/rfbproto/rfbproto/blob/master/rfbproto.rst#setdesktopsize)
support in LibVNCServer and a major cleanup of the project's documentation. Last but not
least, 0.9.13 comes with the usual assortment of bugfixes and security improvements.
## Overall changes:
* Small tweaks to the CMake build system.
* The macOS server example was overhauled and is now the most feature-complete sample
application of the project, ready for real-world use.
* Lots of documentation updates and markdownifying.
* The TravisCI continuous integration now also build-checks cross-compilation from
Linux to Windows.
* Setup a [Gitter community chat](https://gitter.im/LibVNC/libvncserver) for the project.
## LibVNCServer/LibVNCClient:
* Both LibVNCServer and LibVNCClient now support an additional platform, namely
Microsoft Windows. Building is supported with Visual Studio as well as MingGW.
* The separate crypto routines used by LibVNCClient and LibVNCServer were refactored
into an implementation common to both libraries.
* Several security issues got fixed.
* The bundled noVNC client is now at version 1.1.0 and included via a git submodule.
## LibVNCClient:
* Added connect timeout as well as read timeout support thanks to Tobias Junghans.
* Both TLS backends now do proper locking of network operations when multi-threaded
thanks to Gaurav Ujjwal.
* Fixed regression in Tight/Raw decoding introduced in 0.9.12 thanks to DRC.
* Fixed encrypted connections to AnonTLS servers when using the OpenSSL back-end.
Made possible by the profound research done by Gaurav Ujjwal.
## LibVNCServer:
* Added a hooking function (`clientFramebufferUpdateRequestHook`) to deliver
rfbFramebufferUpdateRequest messages from clients to the frame producer
thanks to Jae Hyun Yoo.
* Added SetDesktopSize/ExtendedDesktopSize support thanks to Floris Bos.
* Added multi-threading support for MS Windows.
* Fixed VNC repeater/proxy functionality that was broken in 0.9.12.
* Fixed unstable WebSockets connections thanks to Sebastian Kranz.
Overall changes:
CMake now is the default build system, Autotools were removed.
In addition to TravisCI, all commits are now build-tested by AppVeyorCI.
LibVNCServer/LibVNCClient:
Numerous build fixes for Visual Studio compilers to the extent that
one can now build the project with these. The needed changes for
successfully running stuff will be implemented in 0.9.13.
Fixed building for Android and added build instructions.
Removed the unused PolarSSL wrapper.
Updated the bundled noVNC to latest release 1.0.0.
Allowed to use global LZO library instead of miniLZO.
LibVNCClient:
Support for OpenSSL 1.1.x.
Support for overriding the default rectangle decode handlers (with
hardware-accelerated ones for instance) thanks to Balazs Ludmany.
vnc2mpg updated.
Added support for X509 server certificate verification as part of the
handshake process thanks to Simon Waterman.
Added a TRLE decoder thanks to Wiki Wang.
Included Tight decoding optimizations from TurboVNC thanks to DRC.
Ported the SDL viewer from SDL 1.2 to SDL 2.0.
Numerous security fixes.
Added support for custom auth handlers in order to support additional
security types.
LibVNCServer:
Websockets rework to remove obsolete code thanks to Andreas Weigel.
Ensured compatibility with gtk-vnc 0.7.0+ thanks to Micha K pie .
The built-in webserver now sends correct MIME type for Javascript.
Numerous memory management issues fixed.
Made the TightVNC-style file transfer more stable.
# if __BYTE_ORDER == __BIG_ENDIAN
is always true, and e.g. x11vnc wrongly sets bigEndian in the wire
strucure, causing clients to fail.
Check that __BYTE_ORDER is defined before using it, and add a test for
_BYTE_ORDER too.
Bump PKGREVISION

0.9.9
- Overall changes:
* Added noVNC HTML5 VNC viewer (http://kanaka.github.com/noVNC/) connect possibility
to our http server. Pure JavaScript, no Java plugin required anymore! (But a
recent browser...)
* Added a GTK+ VNC viewer example.
- LibVNCServer/LibVNCClient:
* Added support to build for Google Android.
* Complete IPv6 support in both LibVNCServer and LibVNCClient.
- LibVNCServer:
* Split two event-loop related functions out of the rfbProcessEvents() mechanism.
This is required to be able to do proper event loop integration with Qt. Idea was
taken from Vino's libvncserver fork.
* Added TightPNG (http://wiki.qemu.org/VNC_Tight_PNG) encoding support. Like the
original Tight encoding, this still uses JPEG, but ZLIB encoded rects are encoded
with PNG here.
* Added suport for serving VNC sessions through WebSockets
(http://en.wikipedia.org/wiki/WebSocket), a web technology providing for multiplexing
bi-directional, full-duplex communications channels over a single TCP connection.
* Support connections from the Mac OS X built-in VNC client to LibVNCServer
instances running with no password.
* Replaced the Tight encoder with a TurboVNC one which is tremendously faster in most
cases, especially with high-color video or 3D workloads.
(http://www.virtualgl.org/pmwiki/uploads/About/tighttoturbo.pdf)
- LibVNCClient:
* Added support to only listen for reverse connections on a specific IP address.
* Support for using OpenSSL instead of GnuTLS. This could come in handy on embedded
devices where only this TLS implementation is available.
* Added support to connect to UltraVNC Single Click servers.
0.9.8
- Overall changes:
* Automagically generated API documentation using doxygen.
* Added support for pkg-config.
* Fixed Mingw32 cross compilation.
* Fixed CMake build system.
- LibVNCServer/LibVNCClient:
* All files used by _both_ LibVNCServer and LibVNCClient were put into
a 'common' directory, reducing code duplication.
* Implemented xvp VNC extension.
* Updated minilzo library used for Ultra encoding to ver 2.04.
According to the minilzo README, this brings a significant
speedup on 64-bit architechtures.
- LibVNCServer:
* Thread safety for ZRLE, Zlib, Tight, RRE, CoRRE and Ultra encodings.
This makes all VNC encodings safe to use with a multithreaded server.
* A DisplayFinishedHook for LibVNCServer. If set, this hook gets called
just before rfbSendFrameBufferUpdate() returns.
* Fix for tight security type for RFB 3.8 in TightVNC file transfer
(Debian Bug #517422).
- LibVNCClient:
* Unix sockets support.
* Anonymous TLS security type support.
* VeNCrypt security type support.
* MSLogon security type support.
* ARD (Apple Remote Desktop) security type support.
* UltraVNC Repeater support.
* A new FinishedFrameBufferUpdate callback that is invoked after each
complete framebuffer update.
* A new non-forking listen (reverse VNC) function that works under
Windows.
* IPv6 support. LibVNCClient is now able to connect to IPv6 VNC servers.
* IP QoS support. This enables setting the DSCP/Traffic Class field of
IP/IPv6 packets sent by a client. For example starting a client with
-qosdscp 184 marks all outgoing traffic for expedited forwarding.
Implementation for Win32 is still a TODO, though.
* Fixed hostname resolution problems under Windows.
- SDLvncviewer
* Is now resizable and can do key repeat, mouse wheel scrolling
and clipboard copy and paste.
- LinuxVNC:
* Fix for no input possible because of ctrl key being stuck.
Issue was reported as Debian bug #555988.
alternative from mk/jpeg.buildlink3.mk
This allows selection of an alternative jpeg library (namely the x86 MMX,
SSE, SSE2 accelerated libjpeg-turbo) via JPEG_DEFAULT=libjpeg-turbo, and
follows the current standard model for alternatives (fam, motif, fuse etc).
The mechanical edits were applied via the following script:
#!/bin/sh
for d in */*; do
[ -d "$d" ] || continue
for i in "$d/"Makefile* "$d/"*.mk; do
case "$i" in *.orig|*"*"*) continue;; esac
out="$d/x"
sed -e 's;graphics/jpeg/buildlink3\.mk;mk/jpeg.buildlink3.mk;g' \
-e 's;BUILDLINK_PREFIX\.jpeg;JPEGBASE;g' \
< "$i" > "$out"
if cmp -s "$i" "$out"; then
rm -f "$out"
else
echo "Edited $i"
mv -f "$i" "$i.orig" && mv "$out" "$i"
fi
done
done
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
