There are several motivations for release 3.0 of Cytoscape, but the overriding theme of the release is to refactor/redesign the code so that ''things'' become easier. ''Things'' in this case has several specific meanings:
 * '''Easier''' interface for plugin writers to understand and use.
 * Better modularity or layering making it '''easier''' for components of Cytoscape can be used in different contexts.
 * Clean up/refactor the structure of the existing Cytoscape core so that it can be more '''easily''' maintained, modified, and extended in the future.
 * Make backwards compatibility '''easier''' to maintain.
 * Clean up the user interface so that it's '''easier''' for users.

Release 3.0 Overall Goals

There are several motivations for release 3.0 of Cytoscape, but the overriding theme of the release is to refactor/redesign the code so that things become easier. Things in this case has several specific meanings:

  • Easier interface for plugin writers to understand and use.

  • Better modularity or layering making it easier for components of Cytoscape can be used in different contexts.

  • Clean up/refactor the structure of the existing Cytoscape core so that it can be more easily maintained, modified, and extended in the future.

  • Make backwards compatibility easier to maintain.

  • Clean up the user interface so that it's easier for users.

Desired Features

  • 2.6. The primary feature for Cytoscape 3.0 is to do everything that 2.6 does. See [http://cytoscape.org Cytoscape].
