6.0.0-alpha1

This marks our first release completely integration tested against Elasticsearch 6.0.0-alpha1.

No big changes from 5.4.0 with the notable exception of

• WatcherStatsResponse which has been reworked in Elasticsearch 6.0.0.
• Support for the mapper-attachment plugin is gone (as its also removed from Elasticsearch 6.0.0)

If you have multiple types in a single index you'll need to move to a 1 type per index solution. If you can not do that straight away you can opt in to multiple types for the time being by using mapping.single_type index settings. For instance alpha1 does not come yet with an updated story for parent/child documents mandatory having to live in the same index.

new IndexSettings(new Dictionary<string, object> {
	{ "mapping.single_type", "false" }
})
{
	NumberOfShards = 2,
	NumberOfReplicas = 0,
};

5.4.0

Highlights: Elasticsearch 5.4 feature parity, we are now rolling with the new new csproj files for our builds.

Features & Enhancements

• #2717 Moved to the new new csproj file. Which means we are now on VS2017 and up (or Rider of course!). There's a ton of infrastructure cleanup work behind this ticket.
• #2659 Add stored_fields support to top hits aggregations (ty @V1tOr !)
• #2702 Add support for time_zone in the date range aggregations (ty @adam-mccoy !)
• #2746 Add support for missing highlight options as well as new options that have been introduced in 5.4
• #2743 Add support for the new remote info API
• #2745 Add support for the xpack info AND usage API
• #2748 Expose num_reduce_phases on search (see elastic/elasticsearch#23288)
• #2747 Expose word delimiter graph token filter
• #2744 Add support for the source exists API
• #2742 Add support for the field caps API

Bug Fixes

• #2753 Timeouts on .NET core did not surface the same way they did as on full framework.
• #2735 Do a double read for elasticsearch server errors for requests that can return a valid response for invalid http status codes (_reindex/_update_by_query)
• #2740 reintroduce show_term_document_count_error which went blatently missing in 5.x
• #2720 Dateformat.epoch_millis serialized a mispelled variant (ty @JefStat !)
• #2721 Make sure we can handle fielddata in the old format when mappings are migrated from 2.x to 5.x
• #2759 Fix HttpClient when used on CentOS, does not allow maxconnections to be set.
• #2761 adjacent scripted metric aggregation responses failed to parse properly (ty @konbur)

For 6.0 we will rely on a new feauture in elasticsearch called typed_keys which will return aggregation names prefixed with type# which will completely replace the current heuristics based parser which should make parsing bugs less likely to creep in. (Although the current one has held up OK since 2.x).
