+# Change Log
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](http://keepachangelog.com/)
+
+## [0.6.1] - 2022-11-05
+
+### New Features
+- Expose Class and Endian in the public interface. These types are exposed in the FileHeader type and so they should also be accessible for users to inspect.
+
+## [0.6.0] - 2022-11-01
+
+### New Features
+
+- Add fuzz targets for parts of our ELF parsing interface via cargo-fuzz
+- Add SysVHashTable which interprets the contents of a SHT_HASH section
+- Add StringTable::get_raw() to get an uninterpreted &[u8]
+- Add ParsingTable.len() method to get the number of elements in the table
+- Add some note n_type constants for GNU extension notes.
+- Add default "to_str" feature to get &str for gabi constant names
+
+### Changed Interfaces
+
+- Change File::segments() to return a ParsingTable instead of just a ParsingIterator
+- Change File's SectionHeader interfaces to provide a ParsingTable instead of just a ParsingIterator
+- Remove deprecated File::section_data_for_header() in favor of File::section_data()
+- Remove FileHeader wrapper types OSABI, Architecture, and ObjectFileType
+- Remove ProgramHeader wrapper types ProgType and ProgFlag
+- Remove Symbol wrapper types SymbolType SymbolBind SymbolVis
+- Remove wrapper type SectionType
+- Remove unhelpful SectionFlag wrapper type
+- Remove Display impl for FileHeader, SectionHeader, ProgramHeader, Symbol
+- Remove ParseError::UnsupportedElfVersion in favor of more general ParseError::UnsupportedVersion
+
+### Bug Fixes
+
+- Fix divide by zero panic when parsing a note with alignment of 0 (Error instead of panic)
+- Use checked integer math all over the parsing code (Error instead of panic or overflow)
+- Fix note parsing for 8-byte aligned .note.gnu.property sections (Successfully parse instead of Erroring)
+- Add size validation when parsing tables with entsizes (Error instead of panic)
+
+## [0.5.0] - 2022-10-30
+
+### New Features
+
+- Add File::symbol_version_table() interface to get the GNU extension symbol versioning table
+- Add Symbol.is_undefined() helper to check if a symbol is defined in this object
+- Add File::section_data() which opportunistically parses the CompressionHeader if present
+
+### Bug Fixes
+
+- Fix StringTable to return a ParseError on index out of bounds instead of panicking
+- Fix File::section_data_as_rels to properly parse Rels (not Relas)
+
+## [0.4.0] - 2022-10-24
+
+### New Features
+
+- Add .note section and segment parsing
+- Add .dynamic section and segment parsing
+- Add .rel and .rela section parsing
+- Add File::section_headers_with_strtab to get both a header iter and strtab concurrently.
+
+### Changed Interfaces
+
+- The ReadBytesAt trait was changed to be implemented for an owned CachedReadBytes. This means that File::open_stream now expects to move-own the CachedReadBytes as opposed to taking a mutable reference.
+
+## [0.3.1] - 2022-10-21
+
+### New Features
+- Add File::section_data_for_header() to get raw section data for a given section
+
+### Bug fixes
+- Fix section header table parsing when ehdr.e_shnum > 0xff00
+
+## [0.3.0] - 2022-10-20
+
+### New Features
+- Add a `no_std` option by fully moving the parser over to lazy zero-alloc parsing patterns.
