## [0.0.14] - 2018-1-15
### Changed
- BREAKING: elf: `iter_notes` renamed to `iter_note_headers`
- BREAKING: mach: remove `is_little_endian()`, `ctx()`, and `container()` methods from header, as they were completely invalid for big-endian architectures since the header was parsed according to the endianness of the binary correctly into memory, and hence would always report `MH_MAGIC` or `MH_MAGIC64` as the magic value.
- elf: courtesy of @jan-auer, note iterator now properly iterates over multiple PH_NOTEs
### Added
- mach: added hotly requested feature - goblin now has new functionality to parse big-endian, powerpc 32-bit mach-o binaries correctly

- elf: note iterator has new `iter_note_sections` method
## [0.0.13] - 2017-12-10
### Changed
- BREAKING: remove deprecated goblin::parse method
- BREAKING: ELF `to_range` removed on program and section headers; use `vm_range` and `file_range` for respective ranges
- Technically BREAKING: @philipc added Symtab and symbol iterator to ELF, but is basically the same, unless you were explicitly relying on the backing vector
- 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
- pe: add PE characteristics constants courtesy @philipc
- 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

### Changed
