This release supports materializing as new indexes query-based combinations (crawl mixes) of old search indexes. This should make query performance of crawl mixes much better. Cache pages of search results now have a new history UI that allows you to search cache pages in all indexes you have, much like the way Internet Archive does. Yioop now supports single character edit spell corrections on searches after they have been performed, and it has an API for transliterating between roman and other scripts. Query performance has been improved over previous versions and lots of minor bugs have been fixed.
