…just a small update in case anyone was wondering: I completed an elasticsearch-knapsack export to file from a 0.90.7 (with the plugin built with 0.90.7 dependencies) that was correctly re-imported in a 1.4.2 instance with the latest plugin version, including settings and aliases.
I just checked out the source from github and changed 2-3 lines due to API changes and assembled the plugin to be installed on a 0.90.7 instance. Just wanted to say thanks!
