2009-XX-XX:
    * version 2.2a1pre
    * IMPORTANT: Map.flags has been replaced with individual properties.
      Mappings defined in plugins with mappings.add will need to be updated.
      E.g.
          mappings.add(...,
              { flags: Mappings.flags.ARGUMENT |
                       Mappings.flags.COUNT |
                       Mappings.flags.MOTION |
                       Mappings.flags.ALLOW_EVENT_ROUTING });
      is now
	   mappings.add(...,
               { arg: true, count: true, motion: true, route: true });
    * IMPORTANT: shifted key notation now matches Vim's behaviour. E.g. <C-a>
      and <C-A> are equivalent, to map the uppercase character use <C-S-A>. - Is this still true, or going to be true? --djk
    * add '-javascript' flag to :autocommand
    * add 'private' - enter private browsing mode, matching 'PrivateMode'
      autocommand
    * add -description option to :command
    * command-line options are now supported via the host application's
      -liberator option
    * add ;i and ;I for opening image location (in new tab)
    * add all.html to show all help sections in a single page - available via
      :help all
    * add ;c extended hint mode - open the context menu
    * add @: mapping - repeat the last Ex command
    * add \ mapping - toggle between rendered and source view

2009-05-21:
    * version 2.1
    * IMPORTANT: Default value of 'complete' has been changed from 'sfl' to 'slf'
    * massively speed up :open completions
    * TabMixPlus (and other tab extensions) should work much better now
      together with Vimperator unless you :set guioptions+=[nN]
    * remove 'preload' option. You can fake it by some custom javascript in your init file
    * add :frameonly
    * add :stopall
    * add :tabdo
    * add 'encoding'
    * add 'hintinputs'
    * add :silent

2009-03-28:
    * version 2.0
    * IMPORTANT: For compatibility with vim, guioptions=b has been renamed
      'B'. 'b' now represents the bottom scrollbar.
    * IMPORTANT: :set now sets multiple options, as in Vim. Spaces in values
      must be quoted or escaped.
    * IMPORTANT: Due to much improved autocompletion, changed default 'complete' option
      value to 'sfl', listing intelligent Firefox location bar results. Using 'b' or 'h'
      might cause problems/massive slowdowns, use with care!
    * IMPORTANT: AlwaysHint mode with ;F mode changed the semantics slightly.
    * IMPORTANT: command actions now take an args object, returned from
      commands.parseArgs, as their first argument. This will break any commands
      not using the args parser explicitly.  The old string value is now
      available via args.string.
    * IMPORTANT: 'verbose' is now used for message levels. Logging is
      controlled by the extensions.liberator.loglevel preference.
    * IMPORTANT: :viusage and :exusage now jump to the help index, use the
      special versions for the old behavior.
    * IMPORTANT: renamed Startup and Quit autocmd events to VimperatorEnter and
      VimperatorLeave respectively.
    * IMPORTANT: 'verbose' is now by default at 1, set to 0 to not show any status messages.
    * IMPORTANT: $VIMPERATOR_HOME is no longer used.

    * Selecting an <input type="file"> with hints now causes the commandline to prompt
      for file input (instead of doing nothing).
    * [count]<C-n> now goes to the [count]th next tab rather than the [count]th tab.
    * add ~/.vimperator/info/{profile}/, similar to viminfo
    * add $VIMPERATOR_RUNTIME, $VIMPERATOR_INIT
    * :hardcopy now supports output redirection to a file on Unix and MacUnix
    * add ";f" extended hint mode to focus a frame
    * add "r", "l", and "b" to 'guioptions' to toggle the scrollbars.
    * remove spaces and newlines when open urls starting with http:// or similar
      before :o http://linux .com would search for http://linux and for .com, now
      it just opens linux.com. Also handy when pasting broken urls with p or P.
    * add 'wildcase' option
    * 'linkbgcolor', 'linkfgcolor', ... have been replaced with highlight
      groups, HintElem and HintActive
    * new 'followhints' option
    * :buffers supports a filter now to only list buffers matching filter (vim
      incompatible, but consistent with other commands)
    * Favicon support in many places
    * add 'Fullscreen' autocommmand
    * add :colorscheme
    * multibyte support for hints (thanks Xie&Tian)
    * add 'exrc'

    * add . mapping
    * add N% normal mode command
    * add interpolation for items such as <url> to autocommands

    * add <PageUp>/<S-Up> and <PageDown>/<S-Down> command-line mappings for
      selecting the previous and next history items
    * remove 'hintstyle', 'hlsearchstyle', 't_vb' and 'visualbellstyle' - use
      :highlight {Hint,Search,Bell}
    * add :highlight
    * add :optionusage
    * add :doautocmd and :doautoall
    * add :style and :delstyle commands, allow :so to source stylesheets
    * add DOMLoad autocmd event
    * add :messages and 'messages'
    * add :runtime
    * add 'runtimepath'
    * allow ; hints to work in the multiline output widget
    * add :scriptnames

    * :dialog and :sidebar arguments are now case-insensitive
    * many bug fixes

2008-08-16:
    * version 1.2
    * IMPORTANT: changed :command to behave like Vim's version.
      Eg. An alert command specified previously as
          :command AlertMe alert(args)
      should now be defined as
          :command AlertMe :js alert(<args>)
    * IMPORTANT: changed (again) the default keybinding to temporarily disable all
      Vimperator keybindings from ctrl-q to ctrl-z since many users complained
      about hitting ctrl-q twice and exiting vimperator
    * IMPORTANT: removed old :buffers! buffer window, as it was ugly and slightly broken
      use "B" or :buffers instead
    * IMPORTANT: input fields are not blured anymore by default after a page has loaded
      use :set [no]focuscontent to control the behavior (thanks Paul Sobey for the
      generous donation which made this behavior possible)
    * IMPORTANT: ctrl-x/a never take possible negative URLs into account, it was just
      too unpredictable

    * new 'urlseparator' option for specifying the regexp used to split the arg to
      :open, :tabopen and :winopen
    * :set editor now accepts quoting/escaping to use an editor with spaces in the path
    * support for :%foo as a count for commands (not yet widely used)
    * show informative message when a background tab was loaded, especially useful
      with a hidden tab bar.
    * new "l" flag for 'complete' to reuse the Firefox awesome bar for getting better
      completions for :open. Works only when 'wildoptions' contains "auto" and can
      be a little buggy if you are typing too fast.
    * new wildoptions=auto option (default off for now), to automatically list
      completions without the need to press the tab key
    * new argument parser for ex commands, should tell better error messages when
      you do things like :bmark -tag=a,b instead of :bmark -tags=a,b
