Member macro conformances release for SwiftSyntax

Member macro conformances feature has been implemented in Swift 5.9.2 as mentioned in evolution document. Due to the new protocol requirement introduced as part of this proposal, this requires a release from SwifySyntax with protocol definition update.

While the evolution doc feature is mentioned as implemented the SwiftSyntax release required hasn't happened yet. Is there any timeline on when this release will happen?

Also, for scenarios like this, can the evolution document itself contain the accurate status of implementation?
