@ -5,6 +5,28 @@ All notable (user-facing) changes to this project will be documented in this fil
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
## [2.1.3] - 2024-03-04
### Changed
- Aligned BDDISASM APX instructions syntax with some of the Intel recomandations (using the suffix notation for `NF` and `ZU` indications, using finite set notation for `DFV` operands).
### Disassembly differences
- The `ZU` indication is appended as a mnemonic sufix, as per recomandations. However, in case of `SETcc` instructions, BDDISASM will append the `ZU` indication AFTER the condition code (similar to `CMPccXADD` and with initial `SETcc.ZU` specification).
- The `DFV` (default flags value) operand obeys the finite set notation, but it is placed as the last operand of the instruction.
## [2.1.2] - 2024-02-27
### Added
- `Read` access for the `rIP` operand for the `SYSCALL` instruction.
- `SCS`, `rCX`, `rDX` operands for the `SYSEXIT` instruction.
## [2.1.1] - 2024-02-26
### Added
- `Read` access for the `rIP` operand for some `CALL` instructions.
## [2.1.0] - 2024-02-20
