Full Changelog: v0.4.0...v0.5.0

v0.4.0

• Number of bytestring registers reduced from 256 to 16 (to allow running on a low profile hardware)
• Refactored bytestring instruction set to take into account the aforementioned changes
• Size of data segment reduced to 2^16 (from 2^24)
• Lib uses dynamic set of instructions
• Introduced limits for number of libraries per library (256) and in overall tree (1024)
• Refactored modules
• Better display information for main data types
• Bugfixes in Number from/into convertors
• Completed standalone assembler and linker (see https://github.com/pandoracore/aluasm

v0.3.0

This is first fully-functioning release of AluVM reference implementation! It still lacks some minor rarely-used float types of arithmetics (BFloat16, IEEE binary256, 512-bit tapered float) and advanced bytestring operations, and has small test coverage, but otherwise it is the first version that may be tried in the wild to run deterministic programs.

AluVM rust implementation is subjected to be used as a plug-in library inside runtime environments providing the execution context.

You can see an example of AluVM assembly program, compile and run it here: https://github.com/internet2-org/rust-aluvm/blob/master/examples/asm.rs

New in this release:

• Completed assembler
• Core bytestring operations
• Separation of code, data, linked libraries and ISA extensions segments
• Introduction of library format
• Bech32m-based library identifiers
• Support for external ISA extensions
• Instruction complexity counter and settings

Second MVP

Updates in AluVM v0.2

• Better & new float types and dedicated registers
• Instruction set refactoring
• Clear VM & runtime environment separation

MVP

The initial release of AluVM implementation features:

• Assembly language
• Compiler into bytecode representation
• Bytecode format
• Initial instruction set
• Processor implementation for main instructions
• Registry structure
