snap2
   * Avoid Cleanup Segfault. Avoid Cleanup Segfault. Allocates filepath using
     strdup to avoid segfault is target_dir parameter is not supplied in
     motion.conf. Moves out from signal handler the cleanup for pipe and mpipe.
     (Angel Carpintero)
     http://www.lavrsen.dk/twiki/bin/view/Motion/AvoidCleanupSegfault
   * Major code cleanup concerning signedness of chars all over the code to
     allow compilation with gcc4.0 (like in Fedora Core 4) without any
     errors or warnings. This will probably require that some of the not yet
     included patches will have to be fixed because it it code all over the
     place that has been changed. (Kenneth Lavrsen)

snap3
   * Changed the order of drawing the red mask in setup mode so that the
     smartmask is drawn after the fixed mask (Joerg Weber).
   * Changed the configure script so that /usr/lib64 is also searched for
     the presense of ffmpeg (should fix the problem with 64 bit machines)
     (Kenneth Lavrsen).
   * Changed the configure script so that rpms can be made by normal non-root
     users (Angel Carpintero, Kenneth Lavrsen).

snap4
   * Fixed the ffmpeg code so that Motion also compiles against libavcodec
     build 4754 or later. (Per J鰊sson)
   * Above change in configure script for 64 bit ffmpeg support also implemented
     in the freeBSD configure (Angel Carpintero)
   * Webhttp control interface fixed so it also works in FreeBSD (Angel
     Carpintero)
   * Improved the display of fixed mask. It is now shown as grey instead of
     red. This makes it easier to see the smart mask working when you also have
     a fixed mask (Joerg Weber).
   * Netcam First Header patch. If an error with jpeg decompression occured at
     connecting to a mjpeg streaming webcam, this patch skips this jpeg and tries
     to decompress next jpeg up to MAX_HEADER_RETRIES (20) (Peter Holik).

snap5
   * Small improvement in framerate accuracy (Peter Holik).
     http://www.lavrsen.dk/twiki/bin/view/Motion/FramerateAdjust
   * Fixed a bug in the autobrightness algoritm (Per Johnsson)
   * Fixed a bug in the webhttpd code related to pan/tilt. Bug was introduced in
     snap4 (Angel Carpintero, Kenneth Lavrsen).
   * Improved the labelling algoritm so that locate feature and tracking features
     includes all labelled areas above threshold (Joerg Weber).
     http://www.lavrsen.dk/twiki/bin/view/Motion/ImprovedLabellingPatch
   * Fixed bug reporting errors when creating symlink to last snap (Bill Maidment)
   * Changed all use of localtime to localtime_r which is threadsafe
     (Kenneth Lavrsen).
   * Implemented a modified version of the WebcamCompressInMemory so that Motion
     no longer uses the tmpfile() function for buffering the frames of the mjpeg
     stream (Peter Holik).
     http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory
   * Modified the WebcamCompressInMemory patch so that Motion now supports the
     mjpeg webcam stream while being setup for saving PPM images (Kenneth Lavrsen).
     http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory
   * Major clean-up of code in picture.c and webcam.c so that function names and
     variable names are less confusing. Also added many comments in picture.c.
     (Kenneth Lavrsen).

snap6
   * Webcam code commented more (Kenneth Lavrsen)
   * New improved webcam feature. When you set webcam_motion on Motion will now
     stream at 1 fps instead of none. When motion is detected the webcam stream
     increases to the limit set in the config file. This change makes the
     webcam_motion much more interesting. The previous function always ended up
     with clients timing out. (Kenneth Lavrsen).

snap7
   * Implemented WebcamShortWriteHandling patch (Bill Brack)
     http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamShortWriteHandlingPatch
   * Implemented the libjpeg-mmx patch. Installing the MMX version of libjpeg
     can increase performance. Especially for machines with very little CPU power.
     It only modifies the configure script. If you do not have the libjpeg-mmx
     the configure script with ignore this and use the standard libjpeg.
     Note that RPMS will be built without this (Peter Holik and Angel Carpintero).
     http://www.lavrsen.dk/twiki/bin/view/Motion/LibJpegMmx

snap8
   * Small code cleanup in webcam.c and picture.c and .h for the webcam code
     (Peter Holik and Kenneth Lavrsen)
   * Small code cleanup in motion.c for the variable holding the number of
     microseconds since epoch. The old code worked fine but relied on an integer
     overflow every 71 minutes. (Bill Brack and Kenneth Lavrsen)
   * Implemented a fix/work around to a bug related to building and installing
     RPMs on Suse. (Paul Beltrani)
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x07x14x212356
   * Small speed optimization in the creation of reference frame (Peter Holik).
   * Complete rewrite of the Netcam code. Should fix many of the reported and
     still open netcam bugs. This is first release in a snapshot. Expect to find
     bugs. Testing is important. If you have a netcam please test this and report
     bugs.
     http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamCodeRewritePatch

snap9
   * Fixed bug related to disabled webcam or duplicate webcam port. Error log
     accept(): Socket operation on non-socket continuously written to syslog.
     (Kenneth Lavrsen)
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x01x150922
   * Fixed memory leak in webhttpd related to use of strdup (Angel Carpintero).
   * Improved the error reporting in the Netcam code and did a few minor
     corrections and code cleansups (Bill Brack).
   * Implemented a much easier to use motion_log function which replaces the
     calls to prinf and syslog. The implementation to actually use this has been
     implemented in video.c and the Netcam code files. Rest will be in next snap.
     This code change as no impact to the user (Bill Brack).
     http://www.lavrsen.dk/twiki/bin/view/Motion/ErrorLoggingEnhancementPatch
   * Fixed a bug in video.c so that VIDEO_PALETTE_GREY cameras now actually work
     (Bill Brack).
   * Implemented the conversion of signal to sigaction which should be more
     thread safe. Hopefully this still keeps Motion from making Zombies.
     (Christophe Grenier).
     http://www.lavrsen.dk/twiki/bin/view/Motion/ConvertSignalToSigaction
   * Added new feature: Double size text. A new config option 'text_double' can
     be set 'on' and this scales the text to double size. Default is off.
     (Andrew Hamilton).
     http://www.lavrsen.dk/twiki/bin/view/Motion/TextScalingPatch

snap10
   * Error Logging Enhancement Patch v 1.3 (Angel Carpintero) including:
     http://www.lavrsen.dk/twiki/bin/view/Motion/ErrorLoggingEnhancementPatch
      * Populate the motion_log to the whole motion source code.
      * Fixed FreeBSD copilation.
      * Added the posiblity to pass NULL as struct context *
      * Removed unused errno variables.
      * Fixed errno in rotate.c , set to 0.
      * Fixed some errno flags in webhttpd.c and motion.c
      * Fixed a bug when not motion.conf is found
      * Removed printf from all files
      * Fixed the conf_list[] index in motion.c
   * RotateBswapFix Patch v 2 (Per J鰊sson) including:
      * cleanup in code comments
      * fix for __bswap_32 macro collision
      * fixed bug where initialization would be incomplete for invalid degrees
        of rotation
      * now uses motion_log for error reporting
     http://www.lavrsen.dk/twiki/bin/view/Motion/RotateBswapFix
   * Re-mplementation of optional Proxy Server for Network Cameras (Bill Brack).
     http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamProxyServerPatch
   * Included a CODE_STANDARD text file to help new developers make patches
     that are easier to integrate without too much manual editing. (Kenneth
     Lavrsen)
   * Added the missing rotate feature in the new netcam code (Bill Brack)

snap11
   * Updated the ffmpeg.c code so that Motion can now be built with ffmpeg CVS
     release from the June/July 2005 timeframe (Per J鰊sson).
     http://www.lavrsen.dk/twiki/bin/view/Motion/FfmpegCodecPatch
   * Improved error handling of missing picture frames from camera. Especially
     network cameras will often not be able to provide a picture frame from time
     to time. Motion would retry before and eventually and rather quickly exit
     the camera thread and maybe completely exit. The improved handling now
     makes a copy of the previous frame for 5 seconds (longer if cpu_low is
     activated because the implementation is 5 X framerate frames) and then
     show a grey image with a message saying the connection is lost and an ISO
     format time stamp of first poor connection. (Kenneth Lavrsen).
   * Implemented version 2 of the NetcamErrorImprovementPatch which should
     work with the improved error handler. Changes include:
      * Changes handling of non-streaming camera to include a separate thread.
      * Changes the value returned from netcam_next to the motion main loop to
        indicate the status of the image returned.
      * Many changes to the comments, and some enhancement to the logic, to begin
        the implementation of points agreed on the NetcamRetryErrorDiscussion page.
      * Implements the triple-buffering scheme proposed by PeterHolik (but not the
        "Without Locking" portion of his proposal).
     Version 2 however does not seems to recover when an mjpeg stream resumes
     after a period of not being available. (Bill Brack)
     http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamErrorImprovementPatch
   * Note: Snap11 release as a developer sync release. Bug reports welcome.
     FreeBSD code changes not tested yet.

Release
   * Netcam error handling improvements and cleanup from Walgrind analysis
     (Bill Brack).
   * Added a configure option --with-developer-flags which enables many compiler
     warnings that can be used by developers to make code more robust. Not
     for normal users building Motion (Bill Brack)
   * http-control: Fixed segfault when motion is restarted from command line
     ( kill -s 1 pid_motion ). Improved control code so Motion can Restart and
     Finish 'smoothly'. (Angel Carpintero).
     http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl
   * Changed the 5 second missed camera signal timeout to 30 seconds. (Kenneth
     Lavrsen)
   * Fixed bug where an extra jpeg is saved if you have output_normal=best
     and you stop motion after an event has ended. (Kenneth Lavrsen)

3.2.1   Detailed changes for 3.2.1 since 3.1.19_snap3
snap1
   * Major new feature. XMLRPC is replaced by a simpler http remote control
     interface (implemented by Angel Carpintero)
     http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl

snap2
   * Fixed netcam->userpass problem (Angel Carpintero)
   * Added support in configure for athlon64 from
     http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x30x190907
     (Angel Carpintero and William M Brack)
   * Fixed some gcc warnings (William M Brack)
   * Code cleanup from a valgrind analysis (William M. Brack).

snap3
   * Added Best Preview Patch (Joerg Weber)
     http://www.lavrsen.dk/twiki/bin/view/Motion/BestPreviewShot

snap4
   * Fix for tracking control with http control (Angel Carpintero)
   * Added the new feature Setup Mode (Joerg Weber). This also enables
     much more error messages given to the console when in non-daemon mode
     while still preserving the messages in syslog which are important
     for daemon mode debugging.
     The patch is still being worked on and is not finished.
     Changes in the FreeBSD code are not yet tested.
     http://www.lavrsen.dk/twiki/bin/view/Motion/SetupModePatch
     Remove most command line options and replace them by an option to specify
     location to motion.conf and a few options related to setting up motion.
     (Joerg Weber). This is also included in SetupModePatch.
   * Small improvement of the http control interface (link to setting itself
     on the html response when setting parameter) (Kenneth Lavrsen)
