This version is mainly a maintenance release featuring a slightly reworked interface that improves loading speed.It also fixes a few bugs under the hood.
The WebDAV interface is removed from the free version of Calenco. It is now included as a major rewrite in the professional version.
A "reverse dependencies view" was added. Searching was improved. A new database is used to enhance performance and reduce repository storage size. MathML formulas in PDF output are supported. Many enhancements and bugfixes were made.
DITA and DocBook4 support were added. Support for more languages was added. The file preview area now has two tabs: Preview, with a preview render of the selected file; and Code, with a raw text view which even lets you edit the raw text and store it back on Calenco. Besides the depstree, there's a "flat list" file view that lets you sort files by name, size, type, author. The flat list file view has a search pane, letting you filter out files according to their content (using full-text search).
This release added support for more languages and more help items in the UI, including help on the popup dialogs. In the dependencies tree you must now use Shift+Click to select a file and all of its dependencies. Clicking alone will select the file only, not its dependencies. The REST API specs docs were updated to match the 2.1 implementation. DITA documents are now properly indexed and thus searchable. There were many UI enhancements and bugfixes.
