Yes 1.10 version will be first version for V3 spec. But not all features are implemented on runners such as Spark or Flink.

I thought 1.9.0 already had at least some of the v3 features, like the variant type and column lineages? https://iceberg.apache.org/releases/#190-release

Of course I haven't seen any implementations supporting these yet.

Yes, the specification will be finalized with version 1.10. Previous versions also include specification changes. Iceberg's implementation of V3 occurs in three stages: Specification Change, Core Implementation, and Spark/Flink Implementation.

So far only Variant is supported in Spark and with 1.10 Spark will support nano timestamp and unknowntype I believe.

Any idea when 1.10 will be released?

[talatuyarer]

I believe we are very close to release candidate. We are waiting unknown type support for Apache Spark per latest email
