I've been using the Vector APIs for years now, and I'm still waiting for them to GA!

They are useful for neural information retrieval (RAG, memory), which relies heavily on content vectorization and similarity matching using their dot products.

C# dev here: it’s amazing how different this is from a Microsoft release. First off, Oracle are doing versions at approximately twice the cadence. But also, and I’m guessing this is a function of the much larger Java audience: things rarely get two preview versions in a proper release. Updates in beta versions, yes, all the time. It also feels like Microsoft are bundling a lot more into the platform and leaving less to the community. Again, probably an artifact of the different sizes of the communities. Also, the page reads like an open source “We’re finished, we’re tired.” announcement rather than the razzmatazz of a Microsoft release.

Sorry I only just set -xXx360NoScopexXx=4G to run that latest version without hitting OOM and you are right, it is indeed quite fast with G1.

"The Java Story" documentary by CultRepo on YouTube is pretty great. A major topic is the release cadence which some other comments here are mentioning / joking about.

Project Valhalla will go into Java 28 (next year, and preview version).

Fingers crossed I'll manage to use null type safety in my lifetime.
