API changes
- A lot of changes were made to the rendering functions of the facets to make them more extensible.

New features
- Minimum term length option added to analyzer. This prevents small words from being indexed and searched.
- Added option to keep fieldset expanded when executing a faceted search in the "Advanced search" fieldset.
- Added author facet.

Bug fixes
- Fixed bugs in facets when an array is not passed through the query string.

ZF Components
- To make use of the minimum word length setting, the ZF components must be upgraded to the corresponding alpha3 release.

Bug fixes
- Resolved encoding issue that prevented the search query from being properly parsed on some operating systems.
- Added fix that prevented positive keys from being extracted after the default search field has been changed.

New features
- Improved API that promotes code reuse and extensibility.
- Revamped facet API to allow for easy creation and management of facets.
- Integration with contributed Drupal word stemmers.
- Users can define stop words that are excluded from the index.
- Better performance settings.
- Index statistics to see what has been indexed.
- Various bug fixes and minor improvements.

Backward Compatibility
- The 2.0 API is NOT compatible with 1.0 modules.
- 2.0 indexes are NOT compatible with 1.0 indexes.

Bug fixes:
- Fixed SQL error thrown in admin/settings/search in installations where one or more content types are excluded from the search index.

Bug fixes:

- Added fix to prevent orphaned nodes from remaining in the index. The results showed "Page not found" titles.

- Fixed unclosed bold tag in the Search Lucene Content administration page.

Minor changes:

- Prefixed columns with table names in _luceneapi_node_rewrite_sql() to prevent name clashes.

- Fixed the misnamed title of the "Clear cache" page.

- Added safeguards to prevent the site from throwing fatal errors if the ZF components become unavailable.

Bug fixes:
- Added workaround to prevent plus signs from being converted to spaces when searching or paging through results.
- Wrapped the title of the "Faceted search" fieldset with a t() function call (thx Justin).
- Fixed requirements error that is always thrown by Search Lucene Content during a fresh Drupal install (thx Seth).
- Removed error message when attempting to remove a non-empty index directory on uninstall.
- Added source control files to the mask when removing index files on uninstall, because it is not polite to remove directories that are under version control.

Minor changes:
- Added a nicer message with a link to the installation instructions on the project page for ZF requirement failures on install.
