Recent releases

    Release Notes: This release adds Searchable and Searchables annotations to enable marking prevalent object instance fields as being full-text indexed using Lucene. PrevalentManager has added search methods for executing Lucene queries against the search indices.

    •  20 Jul 2008 11:05

      Release Notes: The user can query for objects based on indexed field(s). Null value fields are indexed, and queries can be based on null value. Metadata features are exposed in PrevalentObject. A bug was fixed in update where modifying non-prevalent objects did not update the index with a new value.

      •  12 Jul 2008 19:10

        Release Notes: The PrevalentManager facade was introduced, which provides an easier interface (similar to JDO PersistenceManager) than the Prevayler API. IndexStorage was modified to reduce memory requirements by not storing objects directly. Add and Update transactions were replaced with a single Save transaction.
