9.4.2

What's Changed

• Add plugin-defined (non-exhaustive) variant registry by @flobernd in #8911
  • Unknown discriminators on variant union families (properties, analyzers, char filters, token filters, tokenizers, repositories, similarity settings, aggregations, queries, etc.) now deserialize into an Unknown* carrier and re-serialize losslessly — no data is dropped for plugin-defined or future variants the client doesn't model
  • Opt into strong typing by registering a CLR type for a discriminator: settings.Variants.Register<IProperty, MyPluginProperty>("my_plugin"); registrations are scoped per client instance and AOT-safe — see the Plugin-defined variant types documentation for details
• Regenerate client by @flobernd in #8908 and #8917
  • Generated Unknown* carrier types for all variant families (properties, analyzers, char filters, token filters, tokenizers, repositories, similarity settings, aggregations, queries, suggesters, rescorers) to support the non-exhaustive variant registry
  • Improved XML documentation coverage across generated client methods, request/response types, and type members that previously had no IntelliSense descriptions

9.4.1

What's Changed

• Regenerate client by @flobernd in #8899 and #8907
  • Fixes (de-)serialization of unions with three or more variants — previously, hand-rolled union converters could fail to select the correct variant
  • Search response shape fix in InnerHits: the Fields property is split into Field (single-field selector using Fields) and a new Fields collection of FieldAndFormat — existing usages of InnerHits.Fields = … may need to be retargeted to Field
  • DataStreamLifecycle gains EffectiveRetention and RetentionDeterminedBy; new GlobalRetention and RetentionSource types; GetDataLifecycleResponse now exposes GlobalRetention
  • Reindex rethrottle response now models parent task progress via the new ParentReindexStatus type
  • Inference and _mvt content-type alignment: chat_completion_unified / stream_completion send Content-Type: application/json; _mvt uses the versioned application/vnd.elasticsearch+vnd.mapbox-vector-tile Accept header
