fix inflate memory leak for segmented architectures 1257 1258 Changes in 0.92 (3 May 95) 1259 - don't assume that char is signed (problem on SGI) 1260 - Clear bit buffer when starting a stored block 1261 - no memcpy on Pyramid 1262 - suppressed inftest.c 1263 - optimized fill_window, put longest_match inline for gcc 1264 - optimized inflate on stored blocks. 1265 - untabify all sources to simplify patches 1266 1267 Changes in 0.91 (2 May 95) 1268 - Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h 1269 - Document the memory requirements in zconf.h 1270 - added "make install" 1271 - fix sync search logic in inflateSync 1272 - deflate(Z_FULL_FLUSH) now works even if output buffer too short 1273 - after inflateSync, don't scare people with just "lo world" 1274 - added support for DJGPP 1275 1276 Changes in 0.9 (1 May 95) 1277 - don't assume that zalloc clears the allocated memory (the TurboC bug 1278 was Mark's bug after all :) 1279 - let again gzread copy uncompressed data unchanged (was working in 0.71) 1280 - deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented 1281 - added a test of inflateSync in example.c 1282 - moved MAX_WBITS to zconf.h because users might want to change that. 1283 - document explicitly that zalloc(64K) on MSDOS must return a normalized 1284 pointer (zero offset) 1285 - added Makefiles for Microsoft C, Turbo C, Borland C++ 1286 - faster crc32() 1287 1288 Changes in 0.8 (29 April 95) 1289 - added fast inflate (inffast.c) 1290 - deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this 1291 is incompatible with previous versions of zlib which returned Z_OK. 1292 - work around a TurboC compiler bug (bad code for b << 0, see infutil.h) 1293 (actually that was not a compiler bug, see 0.81 above) 1294 - gzread no longer reads one extra byte in certain cases 1295 - In gzio destroy(), don't reference a freed structure 1296 - avoid many warnings for MSDOS 1297 - avoid the ERROR symbol which is used by MS Windows 1298 1299 Changes in 0.71 (14 April 95) 1300 - Fixed more MSDOS compilation problems :( There is still a bug with 1301 TurboC large model. 1302 1303 Changes in 0.7 (14 April 95) 1304 - Added full inflate support. 1305 - Simplified the crc32() interface. The pre- and post-conditioning 1306 (one's complement) is now done inside crc32(). WARNING: this is 1307 incompatible with previous versions; see zlib.h for the new usage. 1308 1309 Changes in 0.61 (12 April 95) 1310 - workaround for a bug in TurboC. example and minigzip now work on MSDOS. 1311 1312 Changes in 0.6 (11 April 95) 1313 - added minigzip.c 1314 - added gzdopen to reopen a file descriptor as gzFile 1315 - added transparent reading of non-gziped files in gzread. 1316 - fixed bug in gzread (don't read crc as data) 1317 - fixed bug in destroy (gzio.c) (don't return Z_STREAM_END for gzclose). 1318 - don't allocate big arrays in the stack (for MSDOS) 1319 - fix some MSDOS compilation problems 1320 1321 Changes in 0.5: 1322 - do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but 1323 not yet Z_FULL_FLUSH. 1324 - support decompression but only in a single step (forced Z_FINISH) 1325 - added opaque object for zalloc and zfree. 1326 - added deflateReset and inflateReset 1327 - added a variable zlib_version for consistency checking. 1328 - renamed the 'filter' parameter of deflateInit2 as 'strategy'. 1329 Added Z_FILTERED and Z_HUFFMAN_ONLY constants. 1330 1331 Changes in 0.4: 1332 - avoid "zip" everywhere, use zlib instead of ziplib. 1333 - suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush 1334 if compression method == 8. 1335 - added adler32 and crc32 1336 - renamed deflateOptions as deflateInit2, call one or the other but not both 1337 - added the method parameter for deflateInit2. 1338 - added inflateInit2 1339 - simplied considerably deflateInit and inflateInit by not supporting 1340 user-provided history buffer. This is supported only in deflateInit2 1341 and inflateInit2. 1342 1343 Changes in 0.3: 1344 - prefix all macro names with Z_ 1345 - use Z_FINISH instead of deflateEnd to finish compression. 1346 - added Z_HUFFMAN_ONLY 1347 - added gzerror() 1348
