 ### 💥 Breaking Change
 
+#### EOF removed from Osaka
+
+Following ["Interop Testing Call 34"](https://github.com/ethereum/pm/issues/1499) and the procedural EIPs [PR](https://github.com/ethereum/EIPs/pull/9703) the unfortunate decision to remove EOF from Osaka was made.
+
+To accommodate EOF testing for the interim within EEST, its tests have migrated to a new `tests/speculative` folder. This folder will now contain tests for features that are not yet CFI'd in any fork. When EOF is CFI'd for a fork in the future, all tests will be moved from speculative to the respective future fork folder.
+
+A new fork `EOFv1` has additionally been created to fill and consume EOF related fixtures. Client tests fillers such as `evmone` (and client consumers) will now need to use this fork name.
