Intel® IPP Library 7.0 Bug Fixes List
The tables below summarize specific customer issues or feature requests that have been addressed by the indicated product releases. Some items span multiple architectures and/or operating systems and some relate only to a single architecture or operating system.
NOTE: The issues, defects, bug reports, and feature requests summarized below represent specific issues with specific test cases. An item listed here does not imply that it necessarily applies to your application(s). If your situation does not match the specific test case associated with an item in this list you may not have experienced the problem associated with that update. It is not possible to describe the details of every issue and its specific test case within these tables.
Providing a complete description of each item in the tables below is impractical. For that reason we ask that you post a request for more information on the IPP user forum and reference this page and the "DPD" number of interest, when you have questions regarding specific items in these tables. Where additional information is available the DPD number will contain a link to the detailed explanation in the IPP forum or knowledgebase.
These tables are updated regularly to correct any errors and omissions.
