specially marked. This feature is intended to simplify
trouble-shooting of regular expression searches for single and
multiple-part terms.

<li>Links to images may be accompanied by a <tt>&lt;coords&gt;</tt> tag

href="mapping-skel.txt">skeleton</a>).

<li>Drag-and-drop has been implemented for words that are selected as
the result of a search operation:
<ul>

<li>The highlighting of search words can be controlled by using
parenthesized groups in the regular expression for the search.

<li><acronym title="XML Linking Language">XLink</acronym>s corresponding to
highlighted search words can be dragged from the content pane in which
they appear.

<li>Arboreal keeps better track of what morphology files have already
been loaded.

<li>A portion of the tree may be selected with an 
<acronym title="XML Path Language">XPath</acronym> expression
(<span class="menu">View &gt; Select
<acronym title="XML Path Language">XPath</acronym></span>).
<li><kbd>Ctrl</kbd> + <kbd>.</kbd> (<kbd>Command</kbd> + <kbd>.</kbd> on
the Macintosh) attempts to abort rendering.


<li><acronym title="XML Path Language">XPath</acronym> queries are now
processed more efficiently.

<li>Standard <code>emacs</code> key-bindings work in text input
fields.

<li>Extensions to docspecs system:
<ul>
<li>Text beneath a node can be filtered using Perl substitute syntax
(<code>s/foo/bar/</code>).

<li>The parent of a node can be tested in rendering and filtering rules.

<li>A tag may be specified that serves as a grapheme separator
(implemented for cuneiform texts).

alphabetization in various languages).
</ul>

<h3>Version 2.99</h3>
<ul>
<li>When displaying a page image, a menu option <span
class="menu">View &gt; View large image</span> is available.


<li>A <span class="menu">Find</span> operation displays in the status
bar the number of containers in which there is at least one hit.

refresh the current document, if it has been changed (e.g., with an
external editor).

<li><acronym title="XML Linking Language">XLink</acronym>s for
selected nodes can be dragged from any content pane to any application
that supports drag-and-drop.

<li>File dialogs contain an <span class="menu">Add to
catalog...</span> button.
<ul>

<li>Metadata from
<acronym title="Extensible Markup Language">XML</acronym> texts is
extracted automatically. Rules for what is considered metadata for
various <acronym title="Extensible Markup Language">XML</acronym>
document types are specified with the docspecs system.

<li>If a file does not contain metadata (or does not contain metadata
in a form that Arboreal recognizes), the user is prompted to enter the
data manually.

<li>After catalog entries are accumulated, they can be written out
with <span class="menu">File &gt; Write new catalog.</span> If no
catalog information has been accumulated, this option will write an
empty &quot;skeleton&quot; catalog.

</ul>

<li>Catalog files may contain relative paths. At the time that they
are loaded, relative paths are converted internally to absolute paths
(relative to the base of the
<acronym title="Uniform Resource Locator">URL</acronym> from which
the catalog file was loaded).

<li>A <span class="menu">Window</span> menu contains the titles of all
text windows open in Arboreal.

<li>The term editor has been redesigned to be more ergnonomic and to
offer increased functionality, in accord with the Berlin workshop of
20 June:
<ul>
<li>A list on the right displays all marked instances of the selected
term (in the current text).
<ul>
<li>Selecting an instance in this list allows the user to edit that
term instance.

<li>Double-clicking on an instance opens a new content frame
displaying the container in which the instance is located.
</ul>

<li>A small content pane near the bottom of the term editor displays
the container in which the instance that is being added or edited is
located. This pane is resizeable, and all normal context-menu
functions are available from within it.

<li>At the top of the term editor the current text and language are
indicated. If the user is not currently editing a term instance, s/he
may choose new settings for these options.

<li>Buttons in the term editor have been relabeled and moved to be
more ergonomic.

<li>Red color coding indicates that the instance that has been added
or selected, or that is being edited, belongs to the selected term.

<li>Contextual messages guide the user through the term instance
addition/editing operations.

<li>Term instance parts may be &quot;dragged off&quot; the saturation
bar. With the addition of this operation, Arboreal allows the full
editing of term instances.

<li>The number of instances, both for the current text, and total, is
displayed after the term (e.g., <tt>[5/10]</tt>).

<li>When displaying all term instances, distinct highlighting
differentiates instances of the selected term from instances of other
terms in the same termlist.

<li>When adding multiple term instance parts, all parts remain
highlighted in the content pane from which they were selected.
</ul>

<li>The format of the mapping file has been revised to allow for fully
reversible <i>n</i>-to-<i>n</i> mappings.

<li>The current directory of file dialogs is preserved between
sessions.

<li>Thumbnail images in a content pane are clickable links to view the
full-size image. Link text no longer appears beside the thumbnail.

<li>Arboreal now displays an <span class="menu">Open text</span>
dialog immediately upon loading.

<li>Notable bugfixes
<ul>
<li>Change of display mode for Greek and Arabic now works reliably.

<li>Ports now work in
<acronym title="Uniform Resource Identifier">URI</acronym>s (e.g.,

<tt>http://archimedes.mpiwg-berlin.mpg.de:8080/</tt>).

<li>Many memory leaks have been closed.
</ul>

<li>Technical improvements
<ul>
<li>Arboreal now uses <a
href="http://xml.apache.org/xalan-j/index.html">Xalan 2.4.D1</a> for
<acronym title="XML Path Language">XPath</acronym> processing.
<li>Arboreal now uses Jakarta ORO for regular expression support. See
the <a href="/scrapbook/regex.html">regular expression summary</a>.


<li>Arboreal has been fixed to work with Java 1.4, which is presently
available on Solaris,
<acronym title="GNU's Not Unix">GNU</acronym>/Linux, and Windows. (For
Apple's plans regarding the release of 1.4, see the <a
href="http://developer.apple.com/java/faq/">Java on Max OS X <acronym
title="Frequently Asked Questions">FAQ</acronym></a>.) Cf. <a
href="/scrapbook/Java1.4.html">Arboreal on Java 1.4 notes</a>.

<li>Layout in content panes is done asynchronously, meaning that there
is no longer a long wait when displaying long texts.
</ul>
</ul>

<h3>Version 2.8</h3>
<ul>
<li><span class="menu">View &gt; Open link(s)</span> displays in the
appropriate tree views the targets of all selected

<acronym title="XML Linking Language">XLink</acronym>. If the target texts are not
already open in a tree, Arboreal opens them as new master texts.

<li>Terminology should now be usable for Chinese.

<li>Notable bugfixes
<ul>
<li>Occasional hangs experienced when displaying new content frames
have been eliminated.
</ul>
</ul>

<h3>Version 2.6</h3>
<ul>
<li><span class="menu">Show page image</span> now appears in the
context menu. Selecting it displays the page image corresponding to
the nearest <tt>&lt;pb&gt;</tt>, starting from the top of the
document. For this to work, there must be an image specified as an

<code>xlink:href</code> on that <tt>&lt;pb&gt;</tt>.

<li><span class="menu">Jump to node</span> in the context menu makes
the relevant node visible in the tree.
<li><span class="menu">View &gt; Select subtree(s)</span> now operates
on <b>all</b> the selected paths, not just the lead path.

<li><span class="menu">View all in tree</span> has a cascading menu
with the choices <span class="menu">Add</span> and <span
class="menu">Replace</span>. The old behavior is <span
class="menu">Replace</span>. The new (<span class="menu">Add</span>)
behavior preserves all currently selected nodes in the tree. <li>Major
speedup to the code that resolves <acronym title="XML Path Language">XPath</acronym>/<acronym title="XML Pointer">XPointer</acronym> queries.


<li>ID-based <acronym title="XML Pointer">XPointer</acronym> queries
will now work even if a
<acronym title="Document Type Definition">DTD</acronym> is absent.

<li>A statusbar allows Arboreal to display informative messages. The
messages are coded by priorty levels (WARN, INFO, DEBUG), and a future
release will allow you to filter out those messages you don't want to
see.
</ul>

<h3>Version 2.5</h3>
<ul>
<li>Arboreal is generalized to work with arbitrary <acronym
title="Document Type Definition">DTD</acronym>s through use of
docspecs. See the <a href="/scrapbook/docspecs/">relevant
documentation</a>.


<li><span class="menu">Edit &gt; Copy links</span> copies <acronym
title="XML Linking Language">XLink</acronym> for selected nodes in tree to the
clipboard.

<li>Term editor frame is raised after an illegal operation in term
edit mode, so as to allow operation to be canceled conveniently.

<li>Pressing <kbd>Enter</kbd> functions as a shortcut for <span
class="menu">OK</span> in the find dialog.
</ul>

<h3>Version 2.33</h3>
<ul>
<li>Regular expressions may be used in attribute value searches.

<li>New integrity checking for termlists:
<ul>
<li>Term &quot;name&quot; may not be null.

<li>Some automatic repair of non-conformant termlist files.
</ul>

<li>Major performance improvements to <span class="menu">View in
tree</span>.

</ul>

<h3>Version 2.3</h3>
<ul>
<li>There is now an option to search for attributes. Select the <span
class="menu">Attribute</span> radio button beside <span
class="menu">Search in</span>. You may then type one attribute/value
pair (e.g., &quot;<code>type=head</code>&quot;). [protocol D5]

<li><span class="menu">Cancel</span> now works as expected when
fontifying new text (i.e., bails out).

<li>Application no longer closes unexpectedly when original window is
closed. Arboreal quits only when <em>all</em> main windows have been
closed.


<li>Bug fixes
<ul>
<li>By selecting <span class="menu">View in tree</span> in no-tags
mode, it was possible to get tags in one panel and no tags in another.
<span class="menu">Show tags</span> then merely flipped the states.
FIXED.

<li>A bug prevented preferences from being preserved across sessions
if the directory <code>~/arboreal</code> didn't exist. FIXED.
</ul>
</ul>

<h3>Version 2.28</h3>

<ul>
<li>Termlists have their own colors: these show up in the boxes drawn
around terms as well as in menus. [protocol B2]

<li>Colors can be set through the new configuration facility.

<li>A new configuration facility (with a user-interface within
Arboreal and a new
<acronym title="Extensible Markup Language">XML</acronym> file format
for storing settings) is available. Read its <a
href="/scrapbook/configure.html">documentation</a>.

<li>Searching has been changed a little. You now have the options of
<table border="1">
<tr><td>searching whole document:</td><td><tt><b>[+]</b>From root</tt></td><td><tt><b>[+]</b>Recursive</tt></td></tr>

<tr><td>searching just the selected nodes:</td><td><tt><b>[-]</b>From root</tt></td><td><tt><b>[-]</b>Recursive</tt></td></tr>
<tr><td>searching the subtrees of the selected nodes:</td><td><tt><b>[-]</b>From root</tt></td><td><tt><b>[+]</b>Recursive</tt></td></tr>
</table>

<li>A combo box allows you to choose the text you want to search.

<li>Searching is possible in slave texts. At the moment, the search
must start from the root, and the results must be displayed in a
separate frame; Arboreal will not allow you to change these options.
More flexible searching will come with the next release. [protocol B3]

<li>All morphological features work in slave texts. [protocol B3]

</ul>

<h3>Version 2.1</h3>
<ul>
<li>Thumbnails can be displayed inline in the content pane (in
tags-off mode). Arboreal looks for thumbnails in the subdirectory
<code>thumbs</code> of the directory that contains images. E.g., for
<code>figures/1.jpg</code>, the thumbnail will be
<code>figures/thumbs/1.jpg</code>.
</ul>

<h3>Version 2.02</h3>

<ul>
<li>Terminology highlighting takes the form of a box drawn around
terms; other sorts of highlighting are indicated by shading. Both
types of information are now visible simultaneously. [protocol B2]
</ul>

<h3>Version 2.00b</h3>
<ul>
<li>Current selection in tree is preserved when changing tree levels
(<span class="menu">View &gt; Show tree levels</span>). [protocol A4]

<li>Selecting <span class="menu">View in tree</span> in the popup
context menu takes all nodes visible in the current pane and selects
them in the tree view. [protocol A4]

<li>A new property, <code>defaultlang</code>, can be set in

<code>.arboreal.properties</code>. Any document for which no language
is specified is assumed to be in this language. [<font
color="red"><code>.arboreal.properties</code> is obsolete as of 2.23;
see now <a
href="http://archimedes.fas.harvard.edu/scrapbook/configure.html">Configuring
Arboreal</a></font>]

<li>The link pane (<span class="menu">File &gt; Open links</span>) can
now be closed with "Remove pane" in the popup context menu.

<li>Catalog and canonical name translation services are available.
<ul>

<li>Use <span class="menu">File &gt; Load catalog</span> to load a
catalog file (see <a href="catalog-skel.txt">skeleton</a>). <li>A
default catalog file can be set with the <code>catalog</code> property
in <code>.arboreal.properties</code> [<font
color="red"><code>.arboreal.properties</code> is obsolete as of 2.23;
see now <a
href="http://archimedes.fas.harvard.edu/scrapbook/configure.html">Configuring
Arboreal</a></font>]

</ul>

<li>No longer are there separate online/offline modes.

<li>Terminology functions have been moved under a <span
class="menu">Terms</span> menu.
<ul>
<li>Separate functions are available for loading terms from a file and
for loading terms from the server (database).

<li><span class="menu">Save</span> and <span class="menu">Save
as...</span> functions are now separate. [protocol D1]

<li>Create an empty term list with <span class="menu">New
terms</span>. [protocol D6]


<li>A <span class="menu">Seed terms</span> function allows one to seed
the list of candidate terms with terms from other files. [protocol A5]

<li>A <span class="menu">Close</span> function is also available.

<li>Attempting to close termlists that have been modified results in a
warning. [protocol D1]
</ul>

<li>Multiple termlists can now be open. [protocol A5]
<ul>
<li>Separate termlists are accessed through a cascading ("pull-right")
menu.
</ul>

<li>A combo box in the Term Editor supports viewing of terms in
different languages. [protocol A5]


<li>Arboreal now supports a larger subset of the <a
href="http://ibiblio.org/xml/books/bible2/chapters/ch20.html"><acronym
title="XML Pointer">XPointer</acronym></a> syntax. Arboreal can
process all <acronym title="XML Pointer">XPointer</acronym>
expressions that are valid
<acronym title="XML Path Language">XPath</acronym> expressions;
Arboreal also understands the short form <code>xyz</code> for
<code>id(&quot;xyz&quot;)</code>.

<ul>
<li>When Arboreal generates an
<acronym title="XML Pointer">XPointer</acronym> expression for a
container node in the DOM tree, it references the container's
<code>id</code>, if that is available. If no <code>id</code> is
available, Arboreal generates an
<acronym title="XML Pointer">XPointer</acronym> that references the
node by its relative position in the tree.

<li>Arboreal can only make use of <code>id</code>
<acronym title="XML Pointer">XPointer</acronym>s if the document has a

<acronym title="Document Type Definition">
DTD</acronym> that defines an identifier <code>id</code> of type
<code>ID</code>. Arboreal must be able to see the <acronym
title="Document Type Definition">DTD</acronym> if it is to evaluate
such expressions. [<font color="red">This limitation has been removed
as of 2.6.</font>]
</ul>

<li>Fixed bug involving removal of necessary whitespace during
normalization (e.g., with

<code>&lt;expan&gt;&nbsp;&nbsp;&lt;expan&gt;</code>). [protocol D9]

<li><span class="menu">Open text</span> opens additional master texts
in new frames; these texts share all open terminology lists. [protocol
B1]

<li><acronym title="Extensible Markup Language">XML</acronym> files
pointed to by <acronym title="XML Linking Language">XLink</acronym> can be opened
as new master texts.
</ul>

<h3>Version 1.85</h3>
<ul>

<li>Support for opening links. Links are opened by selecting <span
class="menu">Open link</span> in the popup context menu. A link is any
element with an <code>xlink:href</code> attribute. [protocol A2]
<ul>
<li>The "xlink" namespace should be imported in the <acronym
title="Document Type Definition">DTD</acronym>.
</ul>

<li>Image files pointed to by links can be opened natively in
Arboreal. The following heuristic is used to identify image files: the
<acronym title="Uniform Resource Identifier">URI</acronym> ends in one
of the extensions <code>gif</code>, <code>jpg</code>,

<code>jpeg</code>, <code>png</code>. These extensions represent the
image file formats for which Java currently provides support. Support
for <acronym title="Tagged Image File Format">TIFF</acronym> will be
added to <acronym title="Java Development Kit">JDK </acronym>1.4 and
will be available for Arboreal then. [protocol A1/A2]

<li><acronym title="Uniform Resource Identifier">URI</acronym>s with
<acronym title="XML Pointer">XPointer</acronym>s can be opened in
Arboreal. Currently, only a small subset of the
<acronym title="XML Pointer">XPointer</acronym> syntax is supported.
More will come. [protocol A2]

<li>Arboreal will spawn an external browser (such as Netscape or
Internet Explorer) to display all other links. [protocol A2]


<li>Mapping files use new
<acronym title="Document Type Definition">DTD</acronym> [<font
color="red">link removed: obsolete as of 2.99</font>].

<li>Ability to edit and to remove terms. [protocol A3]
<ul>
<li>Term removal is disabled in online mode.
</ul>
</ul>
