1 | 1.3.0 | ||
2 | * first sv8 release | ||
3 | * major changes in the API (decoder and demuxer are split) | ||
4 | |||
5 | 1.2.3 | ||
6 | * Reduced memory usage and code size. Patch by Peter Pawlowski | ||
7 | |||
8 | 1.2.2 | ||
9 | * Fixed compilation under OpenBSD | ||
10 | * Unix EOF again | ||
11 | |||
12 | 1.2.1 | ||
13 | * Warnings cleanup, patch by Tomas Salfischberger, Thom Johansen and | ||
14 | Daniel Stenberg (Rockbox) | ||
15 | * Mplayer interface, patch by Reimar Doffinger | ||
16 | * Unix EOF everywhere | ||
17 | |||
18 | 1.2 | ||
19 | * 1.1.1 broke the API (BOOL type changed to mpc_bool_t). Version bumped to 1.2 to reflect the major change. Sorry to those who were caught by this error | ||
20 | * Fixed relative/absolute includes (#include "stuff.h" in /include/mpcdec, #include <mpcdec/stuff> in src/) | ||
21 | * Added msvc project files | ||
22 | * Changed mpc_reader_t structure, any specific data of the reader's | ||
23 | implementations should be hidden behind the (void*) data pointer. (example | ||
24 | in default implementation mpc_reader_file) | ||
25 | * Renamed to libmpcdec (to make room for libmpcenc) | ||
26 | |||
27 | 1.1.1 | ||
28 | * fix for fixed-point mode bug | ||
29 | |||
30 | 1.1 | ||
31 | * add compliance & cleanup patches from Michael Roitzsch of xine project | ||
32 | * switch to BSD license | ||
33 | * port to pure C | ||
34 | * add doxygen documentation | ||
35 | * revise API somewhat | ||
36 | |||
37 | 1.0.3 | ||
38 | * autotools build process | ||
39 | * sample binary added | ||
40 | * floating-point mode by default | ||
