ibericode/koko-analytics 1.7.0 on GitHub

Compatibility with sites hosted on WP Engine (which does not allow writing files with the PHP extension to the WP Uploads directory).
Use relative paths in optimized endpoint file, so that the site itself can be moved around freely on the filesystem.
Run aggregator on upgrader_process_complete hook so that we can change aggregation logic without losing any data.
Only use optimized endpoint if the file still exists and is verified to be working. This allows removing the file to immediately switch to the default AJAX endpoint.
Fix a bug in the most viewed posts widget/shortcode that shows all posts instead of an empty result set.
Add group by option to chart.
Better align periods for comparisons.
