Contract keys in future release of 3.x.x

As described in the docs,

Contract keys are not supported in this release of Canton 3.x. Support for non-unique contract keys will come in a future release of Canton 3.x.

So is there the concept somewhwere described or able to use? What’s the version the unique contract keys will be supported in?

@Lukasz2891, in the past, announcements about proposed features have been made at Digital Asset Daml Release Notes. Once such an announcement is made, I’ll try to remember to update this thread too.

Contract Keys (non-unique) were introduced with Canton 3.5.1.
