Hi :) Bug 25669 has stalled on the choice of two options, it needs a confirmation that one of the alternative patches implements indeed one of the two options which is enough for just ES 7 support and raises no question about additional configuration work unlike the other option. https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=25669 Bug 25669 - ElasticSearch 6: [types removal] Specifying types in put mapping requests is deprecated (incompatible with 7) Cheers, -- Victor Grousset/tuxayo
