Dear all,

I am pleased to announce the release of libfuse 3.17.1 (final).

The source code is available for download at https://github.com/libfuse/libfuse/releases.

Please report any issues on this mailing list or the GitHub issue
tracker at https://github.com/libfuse/libfuse/issues.

Release Notes:

First, we apologize for the extended time this release has taken. We wanted to ensure proper ABI compatibility and testing.

Major Changes:

ABI/API Versioning:
    API version remains at 3.x as the API is stable
    SO version increased from 3 to 4 due to ABI issues introduced in 3.11.0 and 3.14.2
    Restored ABI compatibility to 3.10 (fixing incompatibilities introduced in 3.11 and 3.14.2)
    Added automated ABI compatibility tests
    Note: Currently tests only verify against previous tag, not 3.10 yet due to too many false positives.
    Further improvements to the ABI testing are planned.
Version Encoding: The libfuse version is now encoded into programs at compile time using inlined functions in fuse_lowlevel.h and fuse.h
Switched to posix_spawn for better performance with memory-heavy applications and to prevent RDMA-related issues

New Features:

Added support for filesystem passthrough read/write when FUSE_PASSTHROUGH capability is enabled
    New API: fuse_passthrough_open() and fuse_passthrough_close()
    See example/passthrough_hp.cc for usage
Added fmask and dmask options to high-level API for separate permission masks for files and directories
Added signal handling with backtrace printing (fuse_set_fail_signal_handlers())
Added syslog support for fuse_log() messages
    New API: fuse_log_enable_syslog() and fuse_log_close_syslog()
Added thread names to libfuse threads
Fixed buffer misalignment for FUSE_WRITE

libfuse 3.17.1-rc0 Release Notes

First, we apologize for the extended time this release has taken. We wanted to ensure proper ABI compatibility and testing.

Major Changes:

• ABI/API Versioning:
  • API version remains at 3.x as the API is stable
  • SO version increased from 3 to 4 due to ABI issues introduced in 3.11.0 and 3.14.2
  • Restored ABI compatibility to 3.10 (fixing incompatibilities introduced in 3.11 and 3.14.2)
  • Added automated ABI compatibility tests
    Note: Currently tests only verify against previous tag, not 3.10 yet due to too many false positives.
    Further improvements to the ABI testing are planned.
• Version Encoding: The libfuse version is now encoded into programs at compile time using inlined functions in fuse_lowlevel.h and fuse.h
• Switched to posix_spawn for better performance with memory-heavy applications and to prevent RDMA-related issues

New Features:

• Added support for filesystem passthrough read/write when FUSE_PASSTHROUGH capability is enabled
  • New API: fuse_passthrough_open() and fuse_passthrough_close()
  • See example/passthrough_hp.cc for usage
• Added fmask and dmask options to high-level API for separate permission masks for files and directories
• Added signal handling with backtrace printing (fuse_set_fail_signal_handlers())
• Added syslog support for fuse_log() messages
  • New API: fuse_log_enable_syslog() and fuse_log_close_syslog()
• Added thread names to libfuse threads
• Fixed buffer misalignment for FUSE_WRITE

Various minor bugfixes and improvements.

• Readdir kernel cache can be enabled from high-level API.

Future libfuse releases will be signed with signify rather than PGP (rationale). This release is the last to be signed with PGP and contains the signify public key for current (3.15.X) and upcoming (3.16.X) minor release cycle.

• Improved support for some less common systems (32 bit, alternative libcs)

• Unsupported mount options are no longer silently accepted.

• auto_unmount is now compatible with allow_other.

• The extended attribute name passed to the setxattr() handler is no longer truncated at the beginning (bug introduced in 3.13.0).

• As a result of the above, the additional setattr() flags introduced in 3.14 are no longer available for now. They will hopefully be reintroduced in the next release.

• Further improvements of configuration header handling.

• Properly fix the header installation issue. The fix in 3.13.1 resulted in conflicts with other packages.

• Introduce additional setattr() flags (FORCE, KILL_SUID, KILL_SGID, FILE, KILL_PRIV, OPEN, TIMES_SET)

• Fixed an issue that resulted in errors when attempting to compile against installed libfuse headers (because libc symbol versioning support was not detected correctly in this case).
