The Sankaku App is now at version 2.1 in what is admittedly a performance and maintenance update with no topical wall-building or spirit-cooking functionality as yet.
The changes brought by 2.1:
Performance enhancements: Performance when searching through large numbers of posts has been drastically improved.
Bug fixes: Several recurring bugs have been addressed.
Compatibility updates: Various internal SDKs have been brought up to the latest version to improve app compability.
Questions, quandaries, qualms and quibbles are all welcomed via email or comments.
