Unreleased

Removed

3.1.0 - 2019-06-03

Added

Changed

• Keyword indexed is now optional for word typed (bool, int, address, ...) event arguments.
• State variable pretty printing now produce 'a, 'b, ... instead of '1, '2, ....
• ACI is restructured and improved:
  • state and event types (if present) now appear at the top level.
  • Namespaces and remote interfaces are no longer ignored.
  • All type definitions are included in the interface rendering.
  • API functions are renamed, new functions are contract_interface and render_aci_json.
• Fixed a bug in create_calldata/to_sophia_value - it can now handle negative literals.

Removed

3.0.0 - 2019-05-21

Added

• stateful annotations are now properly enforced. Functions must be marked stateful in order to update the state or spend tokens.
• Primitives Contract.creator, Address.is_contract, Address.is_oracle, Oracle.check and Oracle.check_query has been added to Sophia.
• A byte array type bytes(N) has been added to generalize hash (== bytes(32)) and signature (== bytes(64)) and allow for byte arrays of arbitrary fixed length.
• Crypto.ecverify_secp256k1 has been added.

Changed

• Address literals (+ Oracle, Oracle query and remote contracts) have been changed from #<hex> to address as ak_<base58check>, oracle ok_<base58check>, oracle query oq_<base58check> and remote contract ct_<base58check>.
• The compilation and typechecking of letfun (e.g. let m(f, xs) = map(f, xs)) was not working properly and has been fixed.

Removed

• let rec has been removed from the language, it has never worked.
• The standalone CLI compiler is served in the repo aeternity/aesophia_cli and has been completely removed from aesophia.

2.1.0 - 2019-04-11

Added

• Stubs (not yet wired up) for compilation to FATE
• Add functions specific for Calldata decoding
• Support for Auth.tx_hash, not available in AEVM until Fortuna release

Changed

• Improvements to the ACI generator

2.0.0 - 2019-03-11

Added

• Add Crypto.ecverify to the compiler.
• Add Crypto.sha3, Crypto.blake2, Crypto.sha256, String.blake2 and String.sha256 to the compiler.
• Add the bits type for working with bit fields in Sophia.
• Add Namespaces to Sophia in order to simplify using library contracts, etc.
• Add a missig type check on the init function - detects programmer errors earlier.
• Add the ACI (Aeternity Contract Interface) generator.

Changed

• Use native bit shift operations in builtin functions, reducing gas cost.
• Improve type checking of record fields - generates more understandable error messages.
• Improved, more coherent, error messages.
• Simplify calldata creation - instead of passing a compiled contract, simply pass a (stubbed) contract string.
