5 see ChangeLog for details

36 * Linux (ultra)sparc fixes
43 * add support for more Linux architectures (powerpc, sparc, arm)
44 * support lots more Linux syscalls
46 * add IPX and IPIP support

50 Changes in version 3.1
51 ======================
54 * Linux 68k is supported
55 * Linux alpha is supported
56 * configure is upgraded to autoconf 2.x
57 * using -f in combination with -e now works correctly
58 * output can be piped to a program
59 * tracing setuid programs works better
60 * it is now reasonable to install strace setuid to root in some circumstances
61 * new useful tracing names like file and process to trace whole
62 classes of system calls, e.g. -efile traces all system calls that
63 take a file name as an argument
64 * IPC calls on SunOS 4.1.x are decoded
65 * Linux program memory is reliably dereferenced
66 * Linux decodes at least the name of all syscalls as of pre2.0.4
67 * various cosmetic changes and bug fixes
69 Changes from versions 2.x to version 3.0
70 ========================================
72 * filename arguments are neither abbreviated nor stringified
73 * string arguments are now true C strings using octal instead of hex by default
74 * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY)
75 * by default the output for multiple processes now goes into one file
76 * all structures, vectors, bitsets, etc. use consistent output formats
77 * the -c option now means count calls, -i does what the old -c used to do
79 New Features in version 3.0
80 ===========================
82 * non-ascii strings can be optionally printed entirely in hex
83 * the output format is readable when mutiple processes are generating output
84 * exit values are printed in an alignment column
85 * is is possible to suppress messages about attaching and detaching
86 * various tracing features can be enabled on a per syscall/signal/desc basis
87 * selective tracing of syscalls
88 * selective printing of syscall structures
89 * selective abbreviation of long structures on a per syscall basis
90 * selective printing of raw syscall arguments and results
91 * selective tracing of signals
92 * selective dumping of all I/O read from file descriptors
93 * selective dumping of all I/O written to file descriptors
94 * optional counting of time, calls, and errors for each syscall
