HISTORY of the LZMA SDK |
|
|
----------------------- |
|
|
|
|
|
9.38 beta 2015-01-03 |
|
|
------------------------- |
|
|
- The BUG in 9.30-9.37 was fixed: |
|
|
IArchiveGetRawProps interface was disabled for 7z archives. |
|
|
- The BUG in 9.26-9.36 was fixed: |
|
|
Some code in CPP\7zip\Archive\7z\ worked correctly only under Windows. |
|
|
|
|
|
|
|
|
9.36 beta 2014-12-26 |
|
|
------------------------- |
|
|
- The BUG in command line version was fixed: |
|
|
7-Zip created temporary archive in current folder during update archive |
|
|
operation, if -w{Path} switch was not specified. |
|
|
The fixed 7-Zip creates temporary archive in folder that contains updated archive. |
|
|
- The BUG in 9.33-9.35 was fixed: |
|
|
7-Zip silently ignored file reading errors during 7z or gz archive creation, |
|
|
and the created archive contained only part of file that was read before error. |
|
|
The fixed 7-Zip stops archive creation and it reports about error. |
