6 > PLANS: We're now working towards a 1.0 release which is where we plan
7 >       to stabilise the API. We'll be doing test releases before hand,
8 >       but as always we'll like to hear about any bugs found in the
9 >       current release.

93 > libstatgrab 0.10 (20 May 2004)
94 >
95 > * All function and structure names now follow a standardised

98 >
99 >     #define SG_ENABLE_DEPRECATED
100 >     #include <statgrab.h>

103 >   on currently running processes. See sg_get_process_stats
104 >   for details.
105 > * Compare functions provided for process, network, and disk io
106 >   statistics. These can be used with qsort.
107 > * Error reporting functions added. See sg_get_error and
108 >   associated functions.
109 > * Support added for NetBSD 2.0.
110 > * Lots of code tidying.
111 > * Python bindings now exist in a separate package:
112 >     http://www.i-scream.org/pystatgrab/
113 >
114 > libstatgrab 0.9 (10 March 2004)
115 >
116 > * Added network interface information:
117 >     speed, duplex, up/down.

119 >     i/o packets, i/o errors, and collisions.
120 > * Added support for OpenBSD 3.3.
121 > * Added support for DragonFly BSD 1.0.
122 > * No longer need elevated privileges on most platforms:
123 >     FreeBSD 5, NetBSD, and OpenBSD.
124 >     (see PLATFORMS file for details on which OS's need elevated privileges)
125 > * Minor changes to the return types of the python bindings functions.
126 >
127 > * PLEASE NOTE: this will break binary (only) compatibility.
128 >
129 > libstatgrab 0.8.2 (11 February 2004)
