* [FIX] Handle JDBC connection errors appropriately (Adam Hutchison).
* [FIX] Fixing wildcarding of Unicode strings.
* [CHANGE] All indices now respond to a public attributes method.
* [FIX] Improved handling of association searches with real-time indices, including via has_many :though associations (Rob Anderton).
2014-01-11: 3.1.0
* [CHANGE] Updating Riddle requirement to >= 1.5.10.
* [CHANGE] Extracting join generation into its own gem: Joiner.
* [FEATURE] Support for Capistrano v3 (Alexander Tipugin).
* [FEATURE] JRuby support (with Sphinx 2.1 or newer).

* [FIX] Indices will be detected in Rails engines upon configuration.
* [FEATURE] Support for Sphinx 2.2.x's HAVING and GROUP N BY SphinxQL options.
* [FEATURE] Adding max_predicted_time search option (Sphinx 2.2.x).
* [FEATURE] Wildcard/starring can be applied directly to strings using ThinkingSphinx::Query.wildcard('pancakes'), and escaping via ThinkingSphinx::Query.escape('pancakes').
* [CHANGE] Auto-wildcard/starring (via :star => true) now treats escaped characters as word separators.
* [FEATURE] Capistrano recipe now includes tasks for realtime indices.
* [CHANGE] Capistrano recipe no longer automatically adds thinking_sphinx:index and thinking_sphinx:start to be run after deploy:cold.
* [CHANGE] UTF-8 forced encoding is now disabled by default (in line with Sphinx 2.1.x).
* [CHANGE] Sphinx functions are now the default, instead of the legacy special variables (in line with Sphinx 2.1.x).

* [FEATURE] Pass through :delta_options to delta processors (Timo Virkalla).
* [FEATURE] All delta records can have their core pairs marked as deleted after a suspended delta (use ThinkingSphinx::Deltas.suspend_and_update instead of ThinkingSphinx::Deltas.suspend).

* [FIX] Excerpts are now wildcard-friendly.
* [FIX] Facet searches now use max_matches value (with a default of 1000) to ensure as many results as possible are returned.

* [FIX] Default search panes are cloned for each search.
* [FIX] Index-level settings (via set_property) are now applied consistently after global settings (in thinking_sphinx.yml).
* [FIX] All string values returned from Sphinx are now properly converted to UTF8.

* [CHANGE] The current_page method is now a part of ThinkingSphinx::Search, as it is used when populating results.
2013-03-23: 3.0.2
* [CHANGE] per_page now accepts an optional paging limit, to match WillPaginate's behaviour. If none is supplied, it just returns the page size.

* [FEATURE] Indexes defined in app/indices in engines are now loaded (Antonio Tapiador del Dujo).
* [FIX] Custom association conditions are no longer presumed to be an array.
* [CHANGE] Empty search conditions are now ignored, instead of being appended with no value (Nicholas Klick).
* [CHANGE] Custom conditions are no longer added to the sql_query_range value, as they may involve associations.
* [FIX] Capistrano tasks use the correct ts rake task prefix (David Celis).
* [FEATURE] Query errors are classified as such, instead of getting the base SphinxError.
2013-02-04: 3.0.1

* [FIX] Load real-time index definitions when listing fields, attributes, and/or conditions.
* [CHANGE] UTF-8 is now the default charset again (as it was in earlier Thinking Sphinx versions).
* [FEATURE] Initial realtime index support, including the ts:generate task for building index datasets. Sphinx 2.0.6 is required.
* [CHANGE] Removing ts:version rake task.
* [FEATURE] SphinxQL connection pooling via the Innertube gem.
2012-12-22: 3.0.0.rc
* [FEATURE] Source type support (query and ranged query) for both attributes and fields. Custom SQL strings can be supplied as well.

* [FIX] Suppressing delta output in test helpers now works (Darcy Laycock).
* [FEATURE] A custom Riddle/Sphinx controller can be supplied. Useful for Flying Sphinx to have an API layer over Sphinx commands, without needing custom gems for different Thinking Sphinx/Flying Sphinx combinations.
2012-10-06: 3.0.0.pre
* First pre-release. Not quite feature complete, but the important stuff is certainly covered. See the README for more the finer details.
