||
|
|
|
||
|
|
### 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.

|
|
||
|
|
- Change File::segments() to return a ParsingTable instead of just a ParsingIterator
|
||
|

|

|
|
### 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)
|
||
|
|

|
||
|
|

## [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.

||
|
|
|
||
|
|
