• The basic meaning (Grundbedeutung) of a lemma is displayed in the morphology window. (Donatus currently supports this feature for Latin, Greek, and German.)
• In order to drag links from the content pane, it is now necessary to hold down the Ctrl key. This change was motivated by interference between the popup menu and the drag operation.
• The split between the tree and content panes can be switched between horizontal and vertical orientations.
• Tile horizontally and Tile vertically commands have been added to the Window menu.
• It is possible to browse page images with View > Show previous and View > Show next.
• A Print option is available from the context menu in the content pane.
• Word highlights are preserved when changing views (e.g., Toggle tags).
• The Toggle tags menu item now works properly on OS X.

Version 3.1

• The dictionary window allows the user to change dictionaries, if more than one is available for the selected language.

• The mapping file format has been changed (v3) in order to clarify its proper interpretation (see skeleton).
• Drag-and-drop has been implemented for words that are selected as the result of a search operation:
  • The highlighting of search words can be controlled by using parenthesized groups in the regular expression for the search.
  • XLinks corresponding to highlighted search words can be dragged from the content pane in which they appear.

  • Metadata from XML texts is extracted automatically. Rules for what is considered metadata for various XML document types are specified with the docspecs system.
  • 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.
  • After catalog entries are accumulated, they can be written out with File > Write new catalog. If no catalog information has been accumulated, this option will write an empty "skeleton" catalog.
• 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 URL from which the catalog file was loaded).
• A Window menu contains the titles of all text windows open in Arboreal.
• The term editor has been redesigned to be more ergnonomic and to offer increased functionality, in accord with the Berlin workshop of 20 June:
  • A list on the right displays all marked instances of the selected term (in the current text).
    • Selecting an instance in this list allows the user to edit that term instance.
    • Double-clicking on an instance opens a new content frame displaying the container in which the instance is located.
  • 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.
  • 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.
  • Buttons in the term editor have been relabeled and moved to be more ergonomic.
  • Red color coding indicates that the instance that has been added or selected, or that is being edited, belongs to the selected term.
  • Contextual messages guide the user through the term instance addition/editing operations.
  • Term instance parts may be "dragged off" the saturation bar. With the addition of this operation, Arboreal allows the full editing of term instances.
  • The number of instances, both for the current text, and total, is displayed after the term (e.g., [5/10]).
  • When displaying all term instances, distinct highlighting differentiates instances of the selected term from instances of other terms in the same termlist.
  • When adding multiple term instance parts, all parts remain highlighted in the content pane from which they were selected.
• The format of the mapping file has been revised to allow for fully reversible n-to-n mappings.
• The current directory of file dialogs is preserved between sessions.
• Thumbnail images in a content pane are clickable links to view the full-size image. Link text no longer appears beside the thumbnail.
• Arboreal now displays an Open text dialog immediately upon loading.
• Notable bugfixes
  • Change of display mode for Greek and Arabic now works reliably.
  • Ports now work in URIs (e.g., http://archimedes.mpiwg-berlin.mpg.de:8080/).
  • Many memory leaks have been closed.
• Technical improvements
  • Arboreal now uses Xalan 2.4.D1 for XPath processing.
  • Arboreal now uses Jakarta ORO for regular expression support. See the regular expression summary.
  • Arboreal has been fixed to work with Java 1.4, which is presently available on Solaris, GNU/Linux, and Windows. (For Apple's plans regarding the release of 1.4, see the Java on Max OS X FAQ.) Cf. Arboreal on Java 1.4 notes.
  • Layout in content panes is done asynchronously, meaning that there is no longer a long wait when displaying long texts.

Version 2.8

• View > Open link(s) displays in the appropriate tree views the targets of all selected XLink. If the target texts are not already open in a tree, Arboreal opens them as new master texts.
• Terminology should now be usable for Chinese.
• Notable bugfixes
  • Occasional hangs experienced when displaying new content frames have been eliminated.

Version 2.6

• Show page image now appears in the context menu. Selecting it displays the page image corresponding to the nearest <pb>, starting from the top of the document. For this to work, there must be an image specified as an xlink:href on that <pb>.
• Jump to node in the context menu makes the relevant node visible in the tree.
• View > Select subtree(s) now operates on all the selected paths, not just the lead path.
• View all in tree has a cascading menu with the choices Add and Replace. The old behavior is Replace. The new (Add) behavior preserves all currently selected nodes in the tree.
• Major speedup to the code that resolves XPath/XPointer queries.
• ID-based XPointer queries will now work even if a DTD is absent.
• 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.

Version 2.5

• Arboreal is generalized to work with arbitrary DTDs through use of docspecs. See the relevant documentation.
• Edit > Copy links copies XLink for selected nodes in tree to the clipboard.
• Term editor frame is raised after an illegal operation in term edit mode, so as to allow operation to be canceled conveniently.
• Pressing Enter functions as a shortcut for OK in the find dialog.

Version 2.33

• Regular expressions may be used in attribute value searches.
• New integrity checking for termlists:
  • Term "name" may not be null.
  • Some automatic repair of non-conformant termlist files.
• Major performance improvements to View in tree.

Version 2.3

• There is now an option to search for attributes. Select the Attribute radio button beside Search in. You may then type one attribute/value pair (e.g., "type=head"). [protocol D5]
• Cancel now works as expected when fontifying new text (i.e., bails out).
• Application no longer closes unexpectedly when original window is closed. Arboreal quits only when all main windows have been closed.
• Bug fixes
  • By selecting View in tree in no-tags mode, it was possible to get tags in one panel and no tags in another. Show tags then merely flipped the states. FIXED.
  • A bug prevented preferences from being preserved across sessions if the directory ~/arboreal didn't exist. FIXED.

Version 2.28

• Termlists have their own colors: these show up in the boxes drawn around terms as well as in menus. [protocol B2]
• Colors can be set through the new configuration facility.
• A new configuration facility (with a user-interface within Arboreal and a new XML file format for storing settings) is available. Read its documentation.
• Searching has been changed a little. You now have the options of

  searching whole document:	[+]From root	[+]Recursive
  searching just the selected nodes:	[-]From root	[-]Recursive
  searching the subtrees of the selected nodes:	[-]From root	[+]Recursive

• A combo box allows you to choose the text you want to search.
• 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]
• All morphological features work in slave texts. [protocol B3]

Version 2.1

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

Version 2.02

• 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]

Version 2.00b

• Current selection in tree is preserved when changing tree levels (View > Show tree levels). [protocol A4]
• Selecting View in tree in the popup context menu takes all nodes visible in the current pane and selects them in the tree view. [protocol A4]
• A new property, defaultlang, can be set in .arboreal.properties. Any document for which no language is specified is assumed to be in this language. [.arboreal.properties is obsolete as of 2.23; see now Configuring Arboreal]
• The link pane (File > Open links) can now be closed with "Remove pane" in the popup context menu.
• Catalog and canonical name translation services are available.
  • Use File > Load catalog to load a catalog file (see skeleton).
  • A default catalog file can be set with the catalog property in .arboreal.properties [.arboreal.properties is obsolete as of 2.23; see now Configuring Arboreal]
• No longer are there separate online/offline modes.
• Terminology functions have been moved under a Terms menu.
  • Separate functions are available for loading terms from a file and for loading terms from the server (database).
  • Save and Save as... functions are now separate. [protocol D1]
  • Create an empty term list with New terms. [protocol D6]
  • A Seed terms function allows one to seed the list of candidate terms with terms from other files. [protocol A5]
  • A Close function is also available.
  • Attempting to close termlists that have been modified results in a warning. [protocol D1]
• Multiple termlists can now be open. [protocol A5]
  • Separate termlists are accessed through a cascading ("pull-right") menu.
• A combo box in the Term Editor supports viewing of terms in different languages. [protocol A5]
• Arboreal now supports a larger subset of the XPointer syntax. Arboreal can process all XPointer expressions that are valid XPath expressions; Arboreal also understands the short form xyz for id("xyz").
  • When Arboreal generates an XPointer expression for a container node in the DOM tree, it references the container's id, if that is available. If no id is available, Arboreal generates an XPointer that references the node by its relative position in the tree.
  • Arboreal can only make use of id XPointers if the document has a DTD that defines an identifier id of type ID. Arboreal must be able to see the DTD if it is to evaluate such expressions. [This limitation has been removed as of 2.6.]
• Fixed bug involving removal of necessary whitespace during normalization (e.g., with <expan>  <expan>). [protocol D9]
• Open text opens additional master texts in new frames; these texts share all open terminology lists. [protocol B1]
• XML files pointed to by XLink can be opened as new master texts.

Version 1.85

• Support for opening links. Links are opened by selecting Open link in the popup context menu. A link is any element with an xlink:href attribute. [protocol A2]
  • The "xlink" namespace should be imported in the DTD.
• Image files pointed to by links can be opened natively in Arboreal. The following heuristic is used to identify image files: the URI ends in one of the extensions gif, jpg, jpeg, png. These extensions represent the image file formats for which Java currently provides support. Support for TIFF will be added to JDK 1.4 and will be available for Arboreal then. [protocol A1/A2]
• URIs with XPointers can be opened in Arboreal. Currently, only a small subset of the XPointer syntax is supported. More will come. [protocol A2]
• Arboreal will spawn an external browser (such as Netscape or Internet Explorer) to display all other links. [protocol A2]
• Mapping files use new DTD [link removed: obsolete as of 2.99].
• Ability to edit and to remove terms. [protocol A3]
  • Term removal is disabled in online mode.
