Capstone

[ API changes ]

- API version has been bumped to 2.1.
- Change prototype of cs_close() to be able to invalidate closed handle.
See http://capstone-engine.org/version_2.1_API.html for more information.
- Extend cs_support() to handle more query types, not only about supported
architectures. This change is backward compatible, however, so existent code
do not need to be modified to support this.
- New query type CS_SUPPORT_DIET for cs_support() to ask about diet status of
the engine.
- New error code CS_ERR_DIET to report errors about newly added diet mode.
- New error code CS_ERR_VERSION to report issue of incompatible versions between
bindings & core engine.


[ Core changes ]

- On memory usage, Capstone uses about 40% less memory, while still faster
than version 2.0.
- All architectures are much smaller: binaries size reduce at least 30%.
Especially, X86-only binary reduces from 1.9MB to just 720KB.
- Support "diet" mode, in which engine size is further reduced (by around 40%)
for embedding purpose. The price to pay is that we have to sacrifice some
non-critical data fields. See http://capstone-engine.org/diet.html for more
details.


[ Architectures ]

- Update all 5 architectures to fix bugs.
- PowerPC:
- New instructions: FMR & MSYNC.
- Mips:
- New instruction: DLSA
- X86:
- Properly handle AVX-512 instructions.
- New instructions: PSETPM, SALC, INT1, GETSEC.
- Fix some memory leaking issues in case of prefixed instructions such
as LOCK, REP, REPNE.


[ Python binding ]

- Verify the core version at initialization time. Refuse to run if its version
is different from the core's version.
- New API disasm_lite() added to Cs class. This light API only returns tuples of
(address, size, mnemonic, op_str), rather than list of CsInsn objects. This
improves performance by around 30% in some benchmarks.
- New API version_bind() returns binding's version, which might differ from
the core's API version if the binding is out-of-date.
- New API debug() returns information on Cython support, diet status & archs
compiled in.
- Fixed some memory leaking bugs for Cython binding.
- Fix a bug crashing Cython code when accessing regs_read/regs_write/groups.
- Support diet mode.


[ Java binding ]

- Fix some memory leaking bugs.
- New API version() returns combined version.
- Support diet mode.
- Better support for detail option.


[ Miscellaneous ]

- make.sh now can uninstall the core engine. This is done with:

$ sudo ./make.sh uninstall

----------------------------------

Release 2.0 deprecates version 1.0 and brings a lot of crucial changes.

[ API changes ]

- API version has been bumped to 2.0 (see cs_version() API)
- New API cs_strerror(errno) returns a string describing error code given
in its only argument.
- cs_version() now returns combined version encoding both major & minor versions.
- New option CS_OPT_MODE allows to change engine’s mode at run-time with
cs_option().
- New option CS_OPT_MEM allows to specify user-defined functions for dynamically
memory management used internally by Capstone. This is useful to embed Capstone
into special environments such as kernel or firmware.
- New API cs_support() can be used to check if this lib supports a particular
architecture (this is necessary since we now allow to choose which architectures
to compile in).
- The detail option is OFF by default now. To get detail information, it should be
explicitly turned ON. The details then can be accessed using cs_insn.detail
pointer (to newly added structure cs_detail)


[ Core changes ]

- On memory usage, Capstone uses much less memory, but a lot faster now.
- User now can choose which architectures to be supported by modifying config.mk
before compiling/installing.


[ Architectures ]

- Arm
- Support Big-Endian mode (besides Little-Endian mode).
- Support friendly register, so instead of output sub "r12,r11,0x14",
we have "sub ip,fp,0x14".
- Arm64: support Big-Endian mode (besides Little-Endian mode).
- PowerPC: newly added.
- Mips: support friendly register, so instead of output "srl $2,$1,0x1f",
we have "srl $v0,$at,0x1f".
- X86: bug fixes.


[ Python binding ]

- Python binding is vastly improved in performance: around 3 ~ 4 times faster
than in 1.0.
- Cython support has been added, which can further speed up over the default
pure Python binding (up to 30% in some cases)
- Function cs_disasm_quick() & Cs.disasm() now use generator (rather than a list)
to return successfully disassembled instructions. This improves the performance
and reduces memory usage.


[ Java binding ]

- Better performance & bug fixes.


[ Miscellaneous ]

- Fixed some installation issues with Gentoo Linux.
- Capstone now can easily compile/install on all *nix, including Linux, OSX,
{Net, Free, Open}BSD & Solaris.

----------------------------------

- Initial public release.
