-## Known Issues
-
-PR Welcome if you are willing to contribute to one of these issues:
-
-- [ ] Add more unit tests
-
-### ELF
-There are still a few missing implementation of `ElfSection` for completeness:
-
-- [ ] Dynamic Linking Table (`SHT_DYNAMIC`)
-- [ ] Version Symbol Table (`SHT_VERSYM`)
-- [ ] Version Needs Table (`SHT_VERNEED`)
-
-These sections are currently loaded as `ElfCustomSection` but should have their own ElfXXXTable (e.g `ElfDynamicLinkingTable`, `ElfVersionSymbolTable`...)
-
-### DWARF
-
-- [ ] Version 4: support for `.debug_types`, `.debug_frame`, `.debug_loc`, `.debug_ranges`, `.debug_pubnames`, `.debug_pubtypes`, `.debug_macinfo` section
-- [ ] Version 5
-
-### Other file formats
-In a future version I would like to implement the following file format:
-
-- [ ] COFF
-- [ ] Mach-O
