- An CMake issue in `path_util` that caused the compilation to fail was fixed ([!115](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/115)).
- Fixed an issue where `ls` failed because newer kernels use `fstatat()` with `EMPTY_PATH`
- Fixed an issue where `LOG_OUTPUT_TRUNC` did not work as expected ([!118](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/118)).

daemons, the requests are scheduled using the AGIOS scheduling library before
they are dispatched to the shared backend parallel file system.
- The `fsync()` system call is now fully supported.
## Improved
### Improved
- Argobots tasks in the daemon are now wrapped in a dedicated class,
effectively removing the dependency. This lays ground work for future
non-Argobots I/O implementations.
- The `readdir()` implementation has been refactored and improved.
- Improvements on how to the installation scripts manage dependencies.
## Fixed
### Fixed
- The server sometimes crashed due to uncaught system errors in the storage
backend. This has now been fixed.
- Fixed a bug that broke `ls` on some architectures.
