-### Added
-- FATE backend - the compiler is able to produce VM code for both `AEVM` and `FATE`. Many
-  of the APIs now take `{backend, aevm | fate}` to decide wich backend to produce artifacts
-  for.
-- New builtin functions `Crypto.ecrecover_secp256k1: (hash, bytes(65)) => option(bytes(20))`
-  and `Crypto.ecverify_secp256k1 : (hash, bytes(20), bytes(65)) => bool` for recovering
-  and verifying an Ethereum address for a message hash and a signature.
-- Sophia supports list comprehensions known from languages like Python, Haskell or Erlang.
-  Example syntax:
-```
-[x + y | x <- [1,2,3,4,5], let k = x*x, if (k > 5), y <- [k, k+1, k+2]]
-// yields [12,13,14,20,21,22,30,31,32]
-```
-- A new contract, and endpoint, modifier `payable` is introduced. Contracts, and enpoints,
-  that shall be able to receive funds should be marked as payable. `Address.is_payable(a)`
-  can be used to check if an (contract) address is payable or not.
-### Changed
 - New syntax for tuple types. Now 0-tuple type is encoded as `unit` instead of `()` and
   regular tuples are encoded by interspersing inner types with `*`, for instance `int * string`. 
   Parens are not necessary. Note it only affects the types, values remain as their were before,
   so `(1, "a") : int * string`
-- The `AENS.transfer` and `AENS.revoke` functions have been updated to take a name `string`
+
-  instead of a name `hash`.
-- Fixed a bug where the `AEVM` backend complained about a missing `init` function when
-  trying to generate calldata from an ACI-generated interface.
-- Compiler now returns the ABI-version in the compiler result map.
-- Renamed `Crypto.ecverify` and `Crypto.ecverify_secp256k1` into `Crypto.verify_sig` and
-  `Crypto.verify_sig_secp256k1` respectively.
