199 | ------------------------- | |
200 | - The bug was fixed in LzmaDecode.c (ANSI-C LZMA Decoder): | |

202 | decoder could access memory outside of allocated range. | |
203 | - Speed optimization of ANSI-C LZMA Decoder (now it's about 20% faster). | |
204 | Old version of LZMA Decoder now is in file LzmaDecodeSize.c. | |
205 | LzmaDecodeSize.c can provide slightly smaller code than LzmaDecode.c | |
206 | - Small speed optimization in LZMA C++ code | |
