# Changelog
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]
### Added
- Experimental Windows port using MinGW cross compilation toolchain.
- Port to BSD systems.
- Explicit argument invalid error code in `libsquashfs`.
- A `--root-becomes` option to `tar2sqfs` and `sqfs2tar`.

### Changed
- Return propper error code from `sqfs_get_xattr_prefix_id`.
- Return propper error code from `sqfs_compressor_id_from_name`.
- Combined error and value return from `sqfs_compressor_id_from_name`.
- Return error code from compressor functions if input is larger than 2G.
- Lots of cleanups, including the build system.

### Removed
- Entirely redundant `sqfs_has_xattr` function from `libsquashfs`.

### Fixed
- LZO compressor moved out of libsquashfs to avoid licensing problems.
- Make overriding configure variables for LZO library actually work.
- Do not follow symlinks when reading xattrs from input files.
- Ignore directory entry named `./` in tar2sqfs. (#22, #31)
- Reject empty string as directory name in libsquashfs. (#22, #31)
- Fix memory leak in tar2sqfs if entries are skipped.
- Fix tar_fuzz error check after seek.
- Fix the `fstree_init` test to account for defaults from `SOURCE_DATE_EPOCH`.
- Honor the no_xattr flag when generating SquashFS images.
- Block size check in `sqfs_super_init`. (#29)
- Fix pthread block processor interfering with application signal handling.

## [0.7] - 2019-10-08
### Added
- LGPLv3 licensed, shared library `libsquashfs.so` containing all the SquashFS
  related logic.
- Sanitized, public headers and pkg-config file for libsquashfs.
- Doxygen reference manual for libsquashfs.
- Legacy LZMA compression support. (#17)
- User configurable queue backlog for tar2sqfs and gensquashfs.

### Changed
- Make sqfsdiff continue comparing even if the types are different,
  but compatible (e.g. extended directory vs basic directory).
- Try to determine the number of available CPU cores and use the
  maximum by default.
- Start numbering inodes at 1, instead of 2.
- Only store permission bits in inodes, the reader reconstructs them from the
  inode type.
- Make "--keep-time" the default for tar2sqfs and use flag to disable it.

### Fixed
- An off-by-one error in the directory packing code. (#18)
- Typo in configure fallback path searching for LZO library.
- Typo that caused LZMA2 VLI filters to not be used at all.
- Possible out-of-bounds access in LZO compressor constructor.
- Inverted logic in sqfs2tar extended attributes processing.
