100   Internals
101         Git hosting has moved to http://github.com/libguestfs
102
103         The various test directories have been rearranged logically, and now
104         all appear under 'tests/'.
105
106         There is a 'make extra-tests' rule which runs ordinary tests and
107         additional tests, using valgrind to check for memory problems.
108
109         Multiple memory leaks and other problems found by valgrind and fixed.
110
111         Support for optional arguments in the generator has been rewritten
112         to provide more features and safety (Matthew Booth).
113
114         With gcc -fvisibility=hidden is used for internal symbols, avoiding
115         call indirection via the PLT.
116
117         RHashtable functions can be tested in the generator.
118
119         ADD_ARG macro in daemon allows arg lists to be constructed without
120         risk of stack smashing.
121
122         Fix generation of OCaml functions that have more than 10 arguments.
123
124         psmisc has been added to the appliance, allowing use of 'fuser',
125         'killall' and 'pstree' for debugging.
126
127         bindtests now cover RBufferOut and optional arguments (Matthew Booth).

131        - 761460 guestfs_utimens hangs on named pipes

135        - 760000 libguestfs fails to compile with Ruby >= 1.9
136        - 755729 Error message for resize2fs-M needs tweaking
