- 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
