Release 1.0.4

Changes since 1.0.4:

• Added LCFS_MOUNT_FLAGS_TRY_VERITY/tryverity mount option to do best-effort fs-verity
• Use the new loewerdir+ and datadir+ overlayfs mount options from linux 6.6
• mkcomposefs is now multi-threaded when computing digests and copying files
• mkcomposefs now uses copy_file_range when copying files
• Added some initial rust crates to handle composefs dump files
• Added fuzz tests
• Documentation updates
• Fix some crashes and leaks
• Improve error reporting
• Fix build on various libc types and versions

Release 1.0.3

Changes since 1.0.2:

• Image format version 1 was added that allows storing overlay whiteouts in
  a composefs image.
• libcomposefs added max_version option
• mkcomposefs added --version and --max-version options
• composefs can now be build without go-md2man
• Minor bugfix handling file read errors

Release version 1.0.2

Changes since 1.0.1:

• Dropped composefs-from-json in tests in favour of using the
  composefs-info dump format.
• libyajl dependency dropped
• libcomposefs now limits the number of xattrs per file to 64k
• Fixed build against libc without reallocarray
• Performance fixes
• go-md2man is used instead of pandoc for manpages
• Minor fixes to spec file

Release version 1.0.1

Changes since 1.0.0:

• mkcomposefs now supports --from-file which reads image descriptions
  in the format of composefs-info dump output.
• composefs-info dump output now shows content and hardlink target
• mount.composefs now uses the new mount api on recent kernels, which
  fixes a regression in escaping commas in upperdir/lowerdir/workdir
  options.
• lcfs_node_set_payload() now accepts NULL to unset
• Some performance improvements
• Fixed errors in error reporting
• Added more manpages

Release version 1.0.0

This is the first stable release of composefs. Starting now, we
guarantee a stable library ABI and a binary stable file format. The
later means that any image build from an identical lcfs_node tree and
identical write options, will produce a file that is binary identical
to a later run even with a different version. The same is true for
a mkcomposefs run with the same options.

Major changes since 0.1.4:

• Added a soname with version to libcomposefs

• All required overlayfs xattr changes are now upstream and the
  corresponding image generation changes have been made in
  composefs. This includes support for escaping overlayfs xattrs and
  whiteouts for nested overlayfs mounts.

• fs-verity built-in signature support was dropped in favour of
  userspace signatures.

• The erofs images now uses the new bloom filter for faster xattr
  lookups. This is backward compatible and old erofs version still
  work (sans the speedup).

• Files can now be inlined in the erofs image to avoid overhead of
  using redirections for small files.

• There is a new API to regenerate a lcfs_node tree from a composefs
  image file.

• There is a new composefs-info tool that lets you dump info about
  images, including what objects it refers to and which ones are
  missing from a given basedir.

• Various fixes, cleanups and new tests
