v3.0.0

This version is compatible with 960f8d139940fa0814d3fac44da9a2975642f5d3 of clvm

Breaking Change

• The type of None is now undefined (Previously it was null)
• Removed isSExp() and isCLVMObject() since these don't exist in the Python's clvm and they brought slightly different behaviour.
• run_program() has been deprecated. Use run_chia_program or run_clvm instead.
  Note: run_program() is still available, but it cannot handle new CHIP-0011 operators like secp256k1_verify.

Changed

• Now op_div does not accept negative operands.
• convert_atom_to_bytes() now is able to convert an object which has toBytes() method.
• SExp can be initialized from LazyNode of clvm_wasm (Rust version of clvm)
• Upgraded bls-signatures to 2.0.3
• Upgraded npm dev dependencies
• Replaced yarn.lock with pnpm-lock.yaml

Added

• Added clvm_rs(clvm_wasm) support
  • Exposed run_chia_program
  • Exposed run_clvm
  • Exposed LazyNode
    • Added toJSON() method to LazyNode (This is not implemented in clvm_wasm)
  • Exposed Flag
  • Exposed serialized_length
  • Exposed node_from_bytes
• Added asUint8Array() method to Stream
• Added toJSON() method to Bytes
• Added toJSON() method to SExp
• Added tests
• Added example code

Known Issues

• Loading blsjs.wasm into a web browser from ESModule code requires to put the wasm file into url's root path.
  For example, when the main (compiled) js file is loaded by
  <script type='module' src="https://xxx.yyy.zzz/aaa/bbb/ccc/main.js"></script>
blsjs.wasm will be fetched from https://xxx.yyy.zzz/blsjs.wasm.
  This is module context only. if the main js file is not on module context like
  <script defer src="https://xxx.yyy.zzz/aaa/bbb/ccc/main.js"></script>,
  blsjs.wasm will be fetched from https://xxx.yyy.zzz/aaa/bbb/ccc/blsjs.wasm.
  However, with clvm >= 3.0.0, most of bls operations run inside clvm_wasm_bg.wasm.
  So I believe you don't need to load blsjs.wasm in most cases.

v2.0.1

This version is compatible with 480b32840c525e17b5ab2f29036c033febaae71e of clvm

Changed

• Changed error message format if argument of x is a single atom.
  For example, when you run (x (q . 2000)), output will be
  (Prev) FAIL: clvm raise (2000) => (Now) FAIL: clvm raise 2000

v2.0.0

This version is compatible with fc73cd9dc2fc30a1fd461d0f05af9f9679e042c8 of clvm

Breaking Change

The behaviour of op_div has changed. See detailed explanation here

Changed

• Made op_div bug-compatible with clvm_rs
• Replaced npm package @chiamine/bls-signatures with bls-signatures

v1.0.9

This version is compatible with 389efa3fbe65c77600da63c78d29c0866d292754 of clvm

Fixed

• Fixed an issue of as_javascript with tuples inside tuples and ending with 0

v1.0.8

This version is compatible with 2722c78ddb92f067c5025196f397e4d2955f9053 of clvm

Fixed

• Fixed typo in error message
• Fixed an issue where op_substr did not work as expected.
• Fixed an issue where cost calculation for op_subtract was not correct.
• Fixed limbs_for_int return wrong value when argument is 0.
• Fixed an issue where Bytes comparison returns wrong result in some cases.
• Fixed an issue where op_softfork crashed with argument atom larger than or equal to 53bit.
• Fixed G1Element error message.

v1.0.7

This version is compatible with 2722c78ddb92f067c5025196f397e4d2955f9053 of clvm

Added

• Added type declaration file browser/index.d.ts on build.

Changed

• Changed SExp/CLVMObject properties atom and pair to readonly to prevent potential bug.
• Changed src/__bls_signatures__.ts location to src/__bls_signatures__/index.ts to prepare for future wasm-loading tweaks.
• Upgraded @chiamine/bls-signatures to 0.2.1-beta.2.
• Use CLVMType instead of CLVMObject as a valid type representation of CLVMObject.
  (CLVMObject should not be used as a type because there might be number of type incompatibility due to new private field)
