# Changelog
|
|
All notable changes to this project will be documented in this file.
|
|
|
|
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
|
|
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
|
|
|
|
## [Unreleased]
|
|
### Added
|
|
- New builtin function `Crypto.ecrecover_secp256k1: (hash, bytes(65)) => bytes(32)`
|
|
for recovering Ethereum address from message hash and signature.
|
|
|
|
### 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`
|
|
|
|
### Removed
|
|
|
|
## [3.2.0] - 2019-06-28
|
|
### Added
|
|
- New builtin function `require : (bool, string) => ()`. Defined as
|
|
```
|
|
function require(b, err) = if(!b) abort(err)
|
|
```
|
|
- New builtin functions
|
|
```
|
|
Bytes.to_str : bytes(_) => string
|
|
Bytes.to_int : bytes(_) => int
|
|
```
|
|
for converting a byte array to a hex string and interpreting it as a
|
|
big-endian encoded integer respectively.
|
|
### Changed
|
|
- Public contract functions must now be declared as *entrypoints*:
|
|
```
|
|
contract Example =
|
|
// Exported
|
|
entrypoint exported_fun(x) = local_fun(x)
|
|
// Not exported
|
|
function local_fun(x) = x
|
|
```
|
|
Functions in namespaces still use `function` (and `private function` for
|
|
private functions).
|
|
- The return type of `Chain.block_hash(height)` has changed, it used to
|
|
be `int`, where `0` denoted an incorrect height. New return type is
|
|
`option(hash)`, where `None` represents an incorrect height.
|
|
- Event name hashes now use BLAKE2b instead of Keccak256.
|
|
- Fixed bugs when defining record types in namespaces.
|
|
- Fixed a bug in include path handling when passing options to the compiler.
|
|
### 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.
