These release notes only cover the differences from the previous stable/dev branch split (1.16.0). For detailed changelogs, please see the git repository, or the ChangeLog file distributed in the tarball.
- virt-sysprep has been rewritten and expanded (thanks Wanlong Gao) http://libguestfs.org/virt-sysprep.1.html - virt-sparsify --zero is a new option that zeroes the named partition or filesystem - virt-sparsify can now safely sparsify Linux swap partitions - virt-sparsify fixed so it cleans up after ^C http://libguestfs.org/virt-sparsify.1.html - a new tool 'libguestfs-make-fixed-appliance' is provided to build fixed appliances that can be copied to other machines that don't have febootstrap support http://libguestfs.org/libguestfs-make-fixed-appliance.1.html - virt-filesystems now displays the parents (containers) of MD devices and volume groups - virt-alignment-scan, run with no args, displays alignment information for all libvirt domains - virt-df and virt-alignment-scan will display information from all guests even when a disk is inaccessible - virt-rescue new --scratch option to make scratch disks https://rwmj.wordpress.com/2012/04/26/virt-rescue-scratch/#content - virt-make-fs can now be used to create btrfs - virt-edit preserves permissions, UID, GID and SELinux context when editing files - guestfish passes the close event over stdout and remote correctly - guestfish new '--pipe-error' option lets you detect errors in pipe commands - guestfish globs now expand device names - comma and colon characters in filenames now handled correctly by all virt tools
- added support for Fedora 17+ - added support for FreeDOS - added support for Buildroot and Cirros - inspection is now compatible with Windows guests that have been sysprepped (thanks Grant Williamson).
- broad support for btrfs added, including adding multiple devices, fsck, snapshots (thanks Wanlong Gao) - the new 'mount-local' API brings FUSE support directly into the core libguestfs API https://rwmj.wordpress.com/2012/05/14/tip-using-mount-local-api-from-c/#content - new man page: guestfs-performance(1), which contains performance tuning tips http://libguestfs.org/guestfs-performance.1.html - new man page: guestfs-faq(1), Frequently Asked Questions http://libguestfs.org/guestfs-faq.1.html - ENOTSUP (from guestfs_last_errno) is now returned for APIs that are not supported

- The debian/ subdirectory has been removed. We recommend you use the official Debian packages made by Hilko Bengen. http://people.debian.org/~bengen/libguestfs/ http://packages.debian.org/search?keywords=libguestfs - O_CLOEXEC / SOCK_CLOEXEC is now used for almost all file descriptors that the library opens. - posix_fadvise is called when sequentially reading or writing large files. - close all file descriptors and remove all signal handlers in the recovery process - multiple gcc warnings and Coverity bugs have been fixed; many strict-overflow bugs have also been fixed - use ./configure --enable-valgrind-daemon to use valgrind on the daemon; many errors have been fixed - use ./configure --with-qemu-options to pass extra options to qemu - the daemon now has a growable strings buffer type (DECLARE_STRINGSBUF) - the <guestfs.h> header file works with C++ and we have a regression test for this - multiple APIs which should only be called in the CONFIG state now give an error if they are not - .gitignore fixed to use absolute paths - gobject bindings have been expanded, including mapping libguestfs events to gobject signals (thanks Matt Booth) - gobject documentation is generated properly (thanks Matt Booth) - gobject header files now live in a subdirectory - CompareWithString test in the generator now works - FUInt32, FUInt64 struct field types now use the correct XDR type - OCaml tests are now run on bytecode and native code. - java -Xlint:all is used, and all warnings have been fixed - bmptopng, wrestool (etc) missing or failure no longer prints warning messages - ruby: Use RbConfig instead of Config. - PYTHONPATH is set by the ./run script. - appliance building is now thread-safe. - appliance now uses 'ip' instead of 'ifconfig' and 'netstat' commands - several fixes to make parallel builds work properly - guestfish --listen now cleans up properly - the BUSY state has been removed - gettextize has been removed, replaced by a simple Makefile.am - gettext support now covers virt-resize, virt-sparsify and virt-sysprep - better support for the arm architecture
