Full Changelog: v6.0.0...v6.1.0

v6.0.0

This major version release is a rewrite of libzbc introducing significant changes to the API and drops support for draft standards 4.x. Among other changes, compliance to the final ZBC/ZAC standards is improved and now includes support for such ZAC-2/ZBC-2 features as support for DH-SMR (XMR) devices and support for zone counts > 1 in zone operations.
In more details, the main changes from v5.x are as follows.

• remove block and fake backend drivers. The library now has a pure SCSI pass-through datapath
• allow zone counts > 1 for group processing of zone operations
• emulate >1 zone counts if unsupported by the drive. Modify tools and test programs to accept zone count values
• add command handlers for new XMR operations in SCSI and ATA backend drivers
• add new tests for general zone devices and new XMR drives
• add tests for group zone operations
• improve test script performance
• add the API call to get the running libzbc version
• add command line interface fixes for various corner cases
• clean up code, fix typos, get rid of reasonable checkpatch complaints

Version 5.14.0

This release fixes several issues:

• Various typos in the README file
• Simplify and fix zbc_report_zones() to have the backend drivers handle command buffer allocation. This simplification avoids rare issues with report zones command failing due to an invalid command size.
• Do not set the IMMED bit in the SYNCHRONIZE CACHE command issued by zbc_flush() function.
• Fix and improve configuration and compilation of GTK tools

Version 5.13.0

This release improves compilation and rpm builds, documentation and tools. I details:

• Update the README file and add a code of conduct document.
• Improve configure.ac to avoid warning due to the use of deprecated macros. Dependency on autoconf-archive is also removed.
• Various rpm build fixes
• Fix verbose output format
• Improve the detection of ATA devices with the scsi backend driver
• Add the -scsi and -ata option to all command line tools to respectively force the use of the scsi or ata backend drivers.

Version 5.12.0

This new version improves the library versioning to include the release number (in addition to the major and minor version numbers) in the library .so file name.

Version 5.11.1

This minor release fixes the library version information to maintain binary compatibility for users, avoiding the need to recompile an application against a compatible new version of libzbc.

Version 5.11.0

This release brings many improvements to device detection, build improvements and code cleanup.
The following changes are the most notable:

• Increase of the default command timeout from 20s to 30s to be in-line with the kernel default settings. Similarly to the kernel, the timeout for device write cache flush commands is also double the default value (60s).
• Improved handling of timeout errors. These errors are now notified using the ETIMEDOUT error code instead of the generic EIO.
• SCSI backend driver fixes and improvements: optimized SAT correctness detection for ZAC devices and faster device capacity detection
• Block backend driver improvements: retreive the maximum number of open zones from the device sysfs attributes if the kernel expose it.
• Improvement of the zbc_report_zones() function that avoids multiple buffer allocation/free operations for large reports.
• Fixes and Improvements of debug messages

Version 5.10.0

This release provides the following fixes and improvments:

• Fix the block backend driver to always issue a reset zone ioctl
• Fix the fake backend driver zbc_fake_set_write_pointer() function
• Fix the tools command line parsing and error messages
• Add man pages for all tools
• Improved build system
• Improved RPM builds

Version 5.9.0

This release brings many bug fixes and improvements:

• Support for generating rpm packages using "make rpm"
• Compilation warning fixes
• Configuration fixes (header file checks)
• Various tools bug fixes
• Updates to README documentation
  Details can be found in git log.
