| # Changelog | ||
|
|
||
| ## 0.3.0 (2022-11-23) | ||
|
|
||
| - Implemented `call` operation for context-isolated function calls. | ||
| - Added support for custom kernels. | ||
| - Implemented `syscall` operation for kernel calls, and added a new `caller` instruction for accessing the hash of the calling function. | ||
| - Implemented `mem_stream` operation for fast hashing of memory regions. | ||
| - Implemented `adv_pipe` operation for fast "unhashing" of inputs into memory. | ||
| - Added support for unlimited number of stack inputs/outputs. | ||
| - [BREAKING] Redesigned Miden assembly input/output instructions for environment, random access memory, local memory, and non-deterministic "advice" inputs. | ||
| - [BREAKING] Reordered the output stack for Miden assembly cryptographic operations `mtree_set` and `mtree_get` to improve efficiency. | ||
| - Refactored the advice provider to add support for advice maps, and added the `adv.mem` decorator for copying memory regions into the advice map. | ||
| - [BREAKING] Refactored the Assembler and added support for module providers. (Standard library is no longer available by default.) | ||
| - Implemented AIR constraints for the stack component. | ||
| - Added Miden REPL tool. | ||
| - Improved performance with various internal refactorings and optimizations. | ||
|
|
||
| ## 0.2.0 (2022-08-09) | ||
|
|
||
| - Implemented new decoder which removes limitations on the depth of control flow logic. | ||
| - Introduced chiplet architecture to offload complex computations to specialized modules. | ||
| - Added read-write random access memory. | ||
| - Added support for operations with 32-bit unsigned integers. | ||
| - Redesigned advice provider to include Merkle path advice sets. | ||
| - Changed base field of the VM to the prime field with modulus 2^64 - 2^32 + 1. | ||
|
|
||
| ## 0.1.0 (2021-11-16) | ||
|
|
||
| - Initial release (migration of the original [Distaff VM](https://github.com/GuildOfWeavers/distaff) codebase to [Winterfell](https://github.com/novifinancial/winterfell) backend). |
