## Versioning
`aesophia` has a version that is only loosely connected to the version of the
Aeternity node - in principle they will share the major version but not
minor/patch version. The `aesophia` compiler version MUST be bumped whenever
there is a change in how byte code is generated, but it MAY also be bumped upon
API changes etc.
## Interface Modules

# About this release
This is the `aesophia` compiler version 2.0.0. The main changes compared to version 1.2.0 are:
* 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.
* Use native bit shift operations in builtin functions, reducing gas cost.
* Add Namespaces to Sophia in order to simplify using library contracts, etc.
* Simplify calldata creation - instead of passing a compiled contract, simply
pass a (stubbed) contract string.
* Add a missig type check on the `init` function - detects programmer errors earlier.
* Improve type checking of `record` fields - generates more understandable error messages.
* Improved, more coherent, error messages.
* Add the ACI (Aeternity Contract Interface) generator.
