+## High level summary
+
+The Plutus team is finalizing work for the upcoming intra-era hard fork.
+
+Four of the `Value` primitives have now been costed, and the remaining three are currently in progress.
+After this, the final step before will be performing end-to-end testing for all new features to be introduced in the hard fork.
+
+We are also preparing a blog post on UPLC 2025, which will be published soon.
+
+In parallel, we continue progressing on other tasks, including support case analysis related to Data.
