    The 6.5.1 release is delayed

    A Solr bug is delaying 6.5.1, which triggered a discussion about whether we should still get 6.5.1 out and work on getting 6.5.2 released short afterwards, or whether we should wait for the bug to be fixed before building a new release candidate for 6.5.1. Weak consensus seems to be to wait.

    Elasticsearch master is now on Lucene 7

    Elasticsearch master has been upgraded to a Lucene 7 snapshot so that we can start verifying what impact it has for us, especially in terms of disk footprint and performance given changes around sparse norms and doc values. The nightly benchmarks should pick up this change as of tomorrow.
