v 1.2 (October 19, 2003)
	* Find & replace command (Edit/Find & Replace) that clusters the
          matches into similarity groups, so you can see at a glance whether
	  your pattern will be correctly replaced.
	* Changes you make to the pattern library are now saved automatically
	  when you shut down LAPIS, and reloaded automatically when you start
 	  LAPIS again later.
	* Pattern library now runs its patterns automatically and shows
	  how many matches each pattern has on the document. 
	* Region sets can now have regions from multiple documents.  A
	  future LAPIS release will use this feature to make 
	  multiple-document editing easy.
	* LAPIS now uses the standard look and feel of the platform you're
	  running it on: Windows, Macintosh, or Linux.  To change the default
	  look-and-feel, see lapis-1.2/lib/properties.
	* ~/.lapis is now a directory for personal settings, and the old
	  ~/.lapis file is now ~/.lapis/config.  Patterns added to the pattern
	  library are saved in other files in the ~/.lapis directory.
	
v 1.1 (March 18, 2003)
	* Simultaneous Editing mode is much faster
	* Case-sensitive and whole-word options on Pattern pane

v 1.0 (February 27, 2003)
	* web pages can now be edited (to some extent) in WYSIWYG mode
	* Simultaneous Editing mode merged with Selection Guessing mode
	* External parser interface, so that parsers can be written in
	  languages other than Java
	* Brill's part-of-speech tagger incorporated as an external parser;
	  look in English.PartOfSpeech category
	* preliminary XML parser
	* Find & Replace dialog
	* Pattern editor and script editor now appear in sidebar panes
	* ancestor-of and descendant-of pattern operators
	* sort order "ascii" has been renamed more accurately to "unicode"

v 0.99 (April 18, 2002)
	* minor bug fixes
	
v 0.98 (February 6, 2002)
	* switched from gnu.regexp package to Jakarta regexp package, which
	  is at least ten times faster
	* Selection Guessing and Simultaneous Editing dialogs are now displayed
	  as panes on the right side of the browser window
	* literal matches can now produce overlapping region sets
	  (e.g., try matching "aa" against a document containing aaaaa...)

v 0.97 (November 29, 2001)
	* now runs on Mac OS X (thanks to patch from John Gersh)
	* took readlink out of lapis script, so Solaris & Mac OS don't complain
	* other minor bug fixes

v 0.96 (November 8, 2001)
	* outlier highlighting is now available in both selection guessing
	  and simultaneous editing mode.  Turned on and off using checkboxes
	  ("Highlight unusual selections in red") in the mode dialogs.
	* Unusual Matches dialog redesigned
	* new RegionArray data structure for faster pattern matching
	  with monotonic (i.e. non-nested) region sets

v 0.95 (September 6, 2001)
        * Java 1.2 or later is now required. swingall.jar is no longer included.
        * new Selection Guessing mode guesses what multiple selection you
          want to make based on your examples.
        * Simultaneous editing mode now defaults to selection guessing to 
          pick your record set. 
        * Menus and toolbar reorganized
        * Outlier highlighting is now turned off by default.  You can turn it
          back on in the Preferences dialog (Edit/Preferences, SimulEdit tab).

v 0.9 (May 15, 2001)
        * Simultaneous editing mode now highlights the weirdest selections in
          red to call your attention to possible errors.  This technique, called
          outlier highlighting, has a performance cost, so if you'd rather
          not see the outlier highlighting you can turn it off in the Preferences
          dialog (Edit/Preferences, SimulEdit tab).

v 0.8 (April 24, 2001)
        * Improvements in Simultaneous Editing interface.
        * Tcl is now better integrated with LAPIS; Tcl commands run in the 
          Command box now send their output to the browser.
        * Restructured Region and RegionSet class hierarchy.
        * External programs are now killed when Stop is pressed.

v 0.7 (December 8, 2000)
        * Simultaneous editing!

v 0.6 (June 15, 2000)

        * Script optimizer (Optimize toolbar button in Script Editor window) is broken
          right now.

v 0.5 (December 10, 1999)
        * This is an alpha release with a bunch of new Tcl features.
        * Command prompt integrated into Location box. Tcl commands and external commands
          (like "ls -l") can now be typed into the Location box, and their results
          are displayed in the browser.
        * Script editor window (Scripts/Script Editor menu option)
        * Demonstration mode (Scripts/Demonstrate menu option) records a sequence of
          URLs and commands and converts it into a script.
        * Optimizer for eliminating redundant steps in a demonstrated script (see Optimize
          button on Script editor window).
        * Ability to install Tcl scripts as LAPIS tools (in the menubar, toolbar, and
          the Tcl interpreter). See Install button on Script Editor window.
        * Known bugs: too many to list. Follow-up bug-fixing release coming soon.

v 0.4 (August 17, 1999)
        * Preliminary Tcl integration, using Jacl (Java port of Tcl). Documentation
          to follow.
        * Reorganized directory structure for simpler releases.
        * Fixed a bug that prevented switching between Text and HTML mode when a region
          set was highlighted.

        * Fixed a minor bug that prevented default parsers from running.

v 0.3 (July 21, 1999)

        * Feedback button, which pops up a form for submitting bug reports across the Web.

v 0.2 (June 7, 1999)
        * Filtered and Sorted web pages are now rendered properly.
        * TC Editor now has a Run Automatically option, so that a collection of text
          constraints can be invoked automatically any time a document with a certain
          URL pattern or MIME type is loaded.

v 0.1 (May 25, 1999)
        * Initial release.
        * Known bugs: applying Filter or Sort to a web page may produce a 
        * strange-looking web page as a result. For example, hyperlinks in 
        * the result aren't underlined or colored blue (but they can still be clicked).
