Inaccurate status history

Since version 1.8, the history queries are cached via transients, which dramatically improves speed and lowers DB calls during the display of the Orders and Users screens. The trade-off though is that the Orders history column information might be at times inaccurate, as is now rebuilt with some delay of up to 1 hour. If that’s an issue to you, the Bulk action -> Rebuild history cache allows updating the history cache manually.

Additionally, filter oshwoo_cache_ttl, (goes into functions.php), can help control the baseline of how long the cache stays fresh before going stale and rebuilding itself (default is 1h). Example usage:

add_filter( 'oshwoo_cache_ttl', function(){ return 0.5; });
