--------------------------
Bug Fixes
~~~~~~~~~
- Allow building with older elfutils than 0.188 when building with glibc (for musl libc we still need newer versions). (40)
- Improve error reporting when attaching to a process is forbidden. (98)
- Fix a crash that could occur under some unusual conditions if elfutils could not unwind the stack. (101)
- Drop a use of the f-string ``=`` specifier, which wasn't introduced until Python 3.8 (running PyStack with Python 3.7 was failing because of this). (92)
