8.4.0

Features:

• Add Unreal4Crash::parse_with_limit which allows specifying a maximum allocation size when extracting compressed UE4 crash archives. (#447)

Fixes:

• Apply speculative handling of stackless functions only on amd64 when creating CFI caches. (#445)

8.3.2

Features:

• Build and publish binary wheels for arm64 / aarch64 on macOS and Linux. (#442)

Fixes:

• Don’t prefix ARM registers with $ for CFI files. (#443)

8.3.1

Fixes:

• Avoid panic when looking for hex suffixes in multibyte character strings in the demangler. (#430)
• Allow processing of ELF files as long as they have valid program and section headers. (#434)
• Expose dynamic symbols in ELF files. (#421)
• Make dsym_parent accept .framework.dSYM. (#425)

8.3.0

Features:

• Write versioned CFI Cache files. Reading those files is only supported with symbolic versions >= 8.2.1, so trying to use a CFI Cache file with an older version of symbolic will fail with a CfiErrorKind::BadFileMagic error.

Fixes:

• Correctly restore callee saves registers when using compact unwind info.
• Correctly map all DWARF information when using BcSymbolMaps.
• Allow processing of PDB files that have broken inlinee file references.
• Skip duplicated DWARF functions which can lead to inline parent offset overflows.

8.2.1

Features:

• Add support for reading versioned CFI Cache files.

Fixes:

• Avoid quadratic slowdown when using compact unwind info on macOS.

8.2.0

Caution:

• Relevant dependencies such as gimli, goblim, and wasm-related libraries were updated.

Features:

• Support for compact unwind info in MachO files was added, along with special casing of some well known macOS system functions.
• The parser of the Breakpad Format was rewritten.

Bug Fixes:

• All valid STACK WIN record types are being parsed correctly. This did add new variants to the BreakpadStackWinRecordType enum. Technically a breaking change, but we do not consider the Breakpad Parser types as adhering to strict SemVer rules.

8.1.0

Features:

• Add support for loading BCSymbolMaps into MachObjects to un-obfuscate symbol names in bitcode builds. (#336)

Bug Fixes:

• Handle too many files more gracefully. (#374)
• Parse .pdb files containing modules without symbols. (pdb#102)

8.0.5

Bug Fixes:

• Fix detecting hidden Swift symbols in MachObject::requires_symbolmap. Additionally, the MachO symbol iterator no longer strips underscores from __hidden# symbols. (#316)

8.0.4

Manylinux2010 has dropped support for Python 2.7. As a result, we're no longer building or testing the Python package with Python 2.7. This and future releases require at least Python 3.6.

Bug Fixes:

• Compute correct line offsets in symcaches with large gaps between line records. (#319)
• Support symcache lookups for public symbols larger than 65k. (#320)
• Fixed bug that caused functions to have a length of 0 in symcaches. (#324)
• Support debug_addr indexes in DWARF functions. (#326)

8.0.3

Bug Fixes:

• Support DWARF information from MIPS compilers in SHT_MIPS_DWARF sections. (#317)
• Remove a duplicate dependency to two versions of walrus for WASM parsing. (#312)
