		- New sfind filtering in the server side
		- Added new tests (and enabling failing ones) to increase coverage
		- Added docker image (release) for 0.9.6 ([!279](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/279))
		- Added FUSE support([!264](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/264))
		- fuse_client mounting a virtual path exists, avoiding usage of LD_PRELOAD.
		- Added tests for FUSE support



		### Changed
		- Disabled at_parent/at_fork/at_child as it seems unneded now
		- Moved some CMAKE options to config.hpp and env variables ([!285](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/285))
		- LIBGKFS/ GKFS _SYMLINK_SUPPORT, _RENAME_SUPPORT and _CREATE_CHECK_PARENTS.
		- Now all the performance options are in config.hpp and env variables.

		### Fixed
		- SYS_lstat does not exists on some architectures, change to newfstatat ([!269](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/269))
		- We cannot use lstat directly as may cause a recursion call on libc interception.
		- Un/Packing order of directory entries in compressed format was incorrect ([!281](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/281))
		- Fix pytorch mmap ([!291](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/291))
