### Added

- use scroll 0.8.0 and us scroll_derive via scroll
- fix notes including \0 terminator (causes breakage because tools like grep treat resulting output as a binary output...)
### Added

- mach: SizeWith for RelocationInfo
- mach: IOWrite and Pwrite impls for Nlist

## [0.0.12] - 2017-10-29

### Changed
- All binaries formats now have lifetimes
- Elf has a lifetime
- Strtab.new now requires a &'a[u8]
- Strtab.get now returns a scroll::Result<&'a str> (use strtab[index] if you want old behavior and don't care about panics); returning scroll::Error is a bug, fixed in next release

## [0.0.9] - 2017-04-05
### Changed
- Archive has a lifetime
- Mach has a lifetime
