version 0.10 (2010-08-26):
- KDE integration (the possibility to compile Qt-only still exists)
- template files on remote machines can be used using KIO (only in the KDE
  version)
- TikZ source files on remote machines can be loaded, saved and exported
  using KIO (only in the KDE version)
- error messages while generating the preview are shown in the preview
  window itself
- zooming is done in a separate thread now, so the interface is not blocked
  when zooming at large sizes
- a kpart is available that can be used to view TikZ source files in
  konqueror (the kpart opens files having the text/x-pgf mimetype)
- update list of tikz commands
- remove bug which causes ktikz to hang (since Qt 4.6) when typesetting
  a picture
- remove bug: cannot find TikZ documentation when selecting "TikZ Manual"
  in the Help menu, even if configured correctly
- display description of a newly inserted tikz command (using command
  completion or menu) in the statusbar, so that the user still sees the
  usage of a command after it is inserted
- add option to compile the TikZ code only when pushing a "Build" button
- add reload button
- add shell script and ktikz template to the examples directory which can
  be used to generate the preview with the latex; dvips; ps2pdf sequence
  instead of pdflatex (the usage is described in the shell script code)
- check whether the file has changed when ktikz gets the focus (similar
  to kwrite)
- in the kpart check for file changes and reload if there are any (similar
  as in okular)
- the zoom percentage field is now displayed and edited in the user's locale
- added documentation
- remove bug: when the error box is larger than the preview and the next
  compilation does not give errors, the error box is still visible outside
  the area covered by the preview
- try to find or use the default hard-coded (configurable in conf.pri and
  CMakeLists.txt) path to the TikZ documentation when an empty path is
  stored in the local settings (this is the case e.g. when ktikz is run
  for the first time)
- when inserting code using code-completion, the arguments and options that
  must be filled in are marked by a bullet, the bullets can be browsed with
  the Tab-key
- now also an URL to an online version of the TikZ documentation can be
  specified in the configuration dialog
- an icon for Windows and an NSIS Windows Installer script are now available
- the "Insert" menu is now also translated
version 0.9 (2009-09-10):
- remove bug that on startup the item selected in the template combobox
  did not correspond to the text in the lineedit of the combobox
- correct the height of the lineedits in the configuration dialog
- the path to the TikZ documentation must now be set in the configuration
  dialog
- don't wait one second before generating the preview when a file is
  loaded, the template is changed or shell escaping is toggled
- only files are used now as a template file (previously directories
  and everything with a valid path was used), otherwise the default
  template is used
- if the replacement text is empty, then the default template is used
  instead of giving non-informative errors
- when the commands dock is visible (instead of the menu), the code that
  will be inserted is visible in the status bar on hovering the item in
  the list
- clicking on an item in the commands dock only includes the corresponding
  code once (instead of twice)
- added file name completion to the template line edit and the line edits
  in the configuration dialog
- space and tab markers resize according to the font size of the main text
- the color of the space and tab markers can be changed in the
  configuration dialog
- white space and tabulator settings are separate now
- scrolling in the text edit with the arrow keys is faster now
- better completion of \begin{... and \end{...
- allow to use the icons set in KDE4 when the appropriate variable in
  conf.pri is set
- remove bug that the "Next Image" and "Previous Image" buttons remained
  visible when emptying the code text area
- remove bug: statustip of the toggle view actions in the Settings menu is
  not shown when a toolbar or sidebar is hidden on startup
- add support for session management (open windows will be reopened after
  logging out and logging in again)
- added option in the config dialog to enable/disable completion of the
  tikz commands
- trying to open a file from the "Open Recent" menu that does not exist
  anymore does not cause an empty window to be opened anymore, furthermore
  the file is removed from the "Open Recent" list
Version 0.8 (2009-05-25):
- allow text under icons in toolbar
- remove bug: when a second ktikz window is closed while typesetting,
  the cursor is not restored from busy to normal
- remove bug: when the document is untitled and not yet saved, then
  opening a file opens the file in the current window, destroying the
  unsaved text
- added some tikz commands to the list of commands
- disable "Save" and "Save As" actions when the file in the text editor
  is the same as on disk
- replace the "Replace this occurrence" dialog by a widget shown at the
  bottom of the text editor
- added filter "PGF files" in "Open File" dialog
- the previously selected templates can now be selected from a combobox
- added "Clear" button to each line edit
- remove bug: the size of the default font did not change after setting
  a new font size in the config dialog
- new way of writing the temporary latex and pgf files, this also solves
  the bug in which the line numbers in the log window did not correspond
  to the line numbers in the editor
- each time the template is changed a new QTemporaryFile is used, this
  avoids the bug that if the template contains less characters, then the
  bottom of the old template is still there in the file (luckily latex
  stops parsing at the first \end{document}, so this bug was not visible)
- allow to use KDE4 file dialogs when the appropriate variable in conf.pri
  is set
- remove bug (I hope) that caused ktikz to crash when zooming while ktikz
  is typesetting
Version 0.7 (2008-08-26):
- disable previous image button if the first image is shown, disable
  next image button if the last image is shown
- the first time that the End button is pressed the cursor is moved to
  the end of the line (on screen), the second time the cursor is moved
  to the end of the block (end of the line in the file)
- don't run latex on startup when no document is loaded from the command
  line
- adjust size of the viewport in which the preview is displayed when new
  items are added to the tikz picture
- added completion of the tikz commands
- the tikz commands are now loaded from an XML file
- corrected the size of the colored background around the highlighted
  brackets
- remove bug in ConfigDialog::selectFont() (replace "if (&ok)" by "if (ok)")
- the command "New" in the "File" menu now opens a new empty window,
  the commands "Open" and "Open Recent" open the selected file in a new
  window, a "Close" command is added which empties the current window
- the (empty) document is not typesetted anymore when the "Close" command
  (which has the same behavior as the old "New" command) is executed
- add the directory in which the template file is located to the
  $TEXINPUTS environment variable (useful if the template \inputs other
  files)
- layout changes in the configuration dialog

  svn://anonsvn.kde.org/home/kde/trunk/KDE/kdebase/runtime/pics/oxygen/)
Version 0.5 (2007-10-02):
- removed memory leaks
- added Qt logo to the "About Qt" item in the Help menu
- zooming now keeps the same object in the center of the visible area
  that was previously in the center (instead of scrolling to position
  (0,0))
- the tikz commands can be inserted from either a menu or a dockwidget
- more tikz commands are added to the menu/dockwidget
- put the preview area in a dock widget which allows more flexibility
  than a splitter
- added an item in the "Help" menu for opening the file pgfmanual.pdf in
  the PDF viewer configured in the system (if that file is located
  somewhere in the LaTeX texmf tree)
- switched to poppler version 0.6
- removed bug in the config dialog which caused the table items to
  not be shown as disabled upon opening the config dialog when the
  highlighting is set to standard
- added a What's This button in the configuration dialog
- remove crash when zooming at startup before loading or editing tikz
  code
- ktikz now remembers the zoom factor from the previous session
- the application icon is now also installed and is referred to in the
  desktop file (so the icon also appears in the KMenu)
- the build files (*.o *.ui moc_* qrc_*) are now put in a separate build
  directory (when building), leaving the source directory clean
Version 0.4 (2007-08-13):
- added German translation
- show status tip for the "Open Recent" and "Export" submenus
- it is now possible to have more than one image in one document: just
  put the different tikzpictures one below the other in the code and
  then press the "Show previous image" and "Show next image" button to
  browse between the previews (but it is not possible to save or export
  them separately)
- the previous picture is not displayed anymore in the preview when
  the text edit becomes empty (or when the user starts a new document)
- the document modification status is shown correctly now in the title bar
- the preview can be scrolled by dragging the image
- added undo, redo and select all to the Edit menu and to the toolbar
- added comment/uncomment of the current line or selection
- the scrollbars will disappear if the image becomes smaller than the
  view when zooming out
- added a menu with tikz commands
- a better highlighting of the tikz code is implemented based on the
  contents of the tikz commands menu
- made an application icon (I just took the kate icon from oxygen and
  added the text "KTikZ", the text in the icon is in the Fertigo font
  from http://www.josbuivenga.demon.nl/fertigo.html)
- added What's This texts for most widgets and icons
- added a configuration dialog (the highlighting colors and fonts, the
  number of entries in the "Open Recent" menu and the path to pdflatex
  and pdftops can be set)
- messages on standard output are only shown when compiled in debug mode
- in the log box short messages are shown instead of the contents of the
  log file; the contents of the log file can be viewed by pressing the
  "View Log" button
- added an "Abort typesetting" button; for example, typesetting the
  following code never exits:
  \begin{tikzpicture}[x=1cm,y=1cm % note the missing ]
    \draw[->] (0,0) -- (4,0);
  \end{tikzpicture}
- added a context menu to the preview area
- more sensible default sizes for the different widgets in the main
  window on first startup
Version 0.3 (2007-08-06):
- show in the statusbar the position of the cursor in the text edit
- the preview image (in PDF format) is displayed using poppler instead
  of converting the PDF file to PNG first and displaying the PNG file
  (poppler version 0.5.4 is used)
- added zooming of the image (using poppler)
- export to PNG is done directly in Qt now; as a consequence (of this
  and of using poppler to display the preview image) ktikz no longer
  depends on ImageMagick
- added "Open Recent" menu
- if ktikz is run on the command line, then it loads the first argument
  (if it is a valid file name)
- the open/save file dialog remembers the last directory in which a
  PGF source file was opened/saved
- loading of translations if available
- added French translation
- changed qmake files so that the files will be installed in the correct
  place (the installation prefix can be configured in the file conf.pri)
- the wait cursor is displayed while typesetting the PGF picture to PDF
Version 0.2 (2007-08-02):
- replaced the icons in XPM format by icons in PNG format from KDE4's
  Oxygen theme (obtained from
  svn://anonsvn.kde.org/home/kde/trunk/KDE/kdelibs/pics/oxygen)
- placed the text edit and the preview area in a splitter so that their
  relative width can be changed by the user
- placed the log text edit in a dockwidget (which can be hidden)
- temporary files are now put in QDir::tempPath() + "/ktikz"
  (on Linux this is /tmp/ktikz), so your working directory remains clean
- closing the application now removes all temporary files and stops the
  thread
- the first time that the thread (generating the output image) is
  executed is not on startup anymore, but when the user actually
  changes the text or loads a file
- images can now be exported to EPS, PDF and PNG
- for some standard actions, the standard key sequence is used (e.g.
  QKeySequence::Open instead of Ctrl+O)
- the toolbars can be hidden
- corrected typo "TiKz" to "TikZ"
- a function runProcess is used which makes the code of generatePdfFile
  and generatePngFile easier (in tikzpngpreviewer.cpp)
- made a better about dialog
