Changelog

Language

General

  • implemented the module system with access to the root and parent modules
  • allowed declaring constants, types, functions, and modules in arbitrary order
  • added aliases to the use import statement
  • implemented unit-testing functionality
  • renamed the assert! function to require

Object-oriented

  • added methods with by-value self instance parameter
  • added the syntax sugar for calling methods via the dot . operator

Compile-time

  • extended constant expressions with arrays, tuples, structures, blocks, conditionals, and matches
  • implemented primitive constant functions

Expressions

  • fixed the issue where operations on enums could result into an invalid variant
  • allowed bitwise operations on non-constant and witness values
  • forbidden bitwise operations on signed integers and fields
  • implemented the type inference for integer literals in expressions
  • added the exponent notation of integer literals
  • implemented declaration of multiple variables via tuple destructuring
  • removed the mandatory semicolon after block, conditional, and match expressions

Compiler

  • fixed the bug where namespace items where resolved from outside the namespace
  • fixed the bug where the type of match enumeration variant path pattern used to be unchecked
  • fixed the bug where a structure could be initialized without fields
  • implemented the per-entry dead code elimination optimization for unreachable functions
  • implemented the short-circuiting boolean expressions evaluation
  • improved some error messages

Virtual machine

  • added the overflow checking and enum validation for input JSON files
  • allowed witness array indexes without constraints
  • improved some error messages

Zargo

  • generalized for managing both circuit and smart contract projects
  • improved some commands and default values to decrease redundancy
  • added some commands for publishing and working with smart contracts
  • taught Zargo to mimic Cargo more accurately

Source code

  • added doc comments for the entire project using missing_docs_* lints
  • moved some shared data to crates:
    • zinc_logger
    • zinc_const
    • zinc_math
    • zinc_manifest
    • zinc_source
    • zinc_build
    • zinc_zksync

Overall

  • implemented basic smart contracts
  • developed the Zandbox application for publishing and running smart contracts

Changelog

Language

  • forbidden the division operator /, but implemented std::ff::invert for field inversion
  • allowed casting to types with lesser bitlength (runtime error on overflow)
  • added the bitwise operators |, |=, ^, ^=, &, &=, <<, <<=, >>, >>=, ~ (constant expressions only)
  • added the binary (e.g. 0b101010) and octal (e.g. 0o52) integer literals
  • implemented match exhaustiveness checking without the binding or wildcard pattern
  • removed static statements for global variables (use const instead)
  • limited match scrutinee expression to boolean and integer only, since it is impossible to destructure complex types for now
  • reserved some keywords (see Appendix C of the Zinc book)

Compiler

  • fixed the bug with ! while passing a non-builtin function call as a built-in one's argument
  • fixed the bug with duplicate match expression branches

Overall

  • added a wrapper directory to the release archives to prevent tar- and zip-bombs

Changelog

Language

  • added the Schnorr signature verification to the standard library
  • made enumerations strongly typed, not just groups of constants
  • match scrutinee can be any expression again (including structure literals)
  • implemented automatic loop bounds range type upcasting
  • implemented arithmetic assignment operators (+=, -=, *=, /=, %=)
  • allowed constant expressions as array sizes (both types and literals)
  • field division (i.e. multiplication by inverted value)
  • field comparison (treated as unsigned numbers)

Compiler

  • implemented advanced errors with Rust-like formatting, hints, location pointers
  • added constant overflow checking at compile-time
  • the constant expression Euclidean division and remainder now works just like in VM

Virtual machine

  • fixed 'unconstrained' variables in hash functions
  • fixed constraint generation when the same variable is encountered multiple times in the same expression

Changelog

Language
