Intel QPL v0.3.0

Usability and Documentation

• Changed libaccel-config.so to a build time dependency on Linux instead of loading it for Hardware Path execution at runtime, it is now required to add -laccel-config when building the application with QPL
• Fixed duplications in status codes documentation page in Developer Reference

Deprecated Functionality

• Dropped support of qpl_op_set_membership, qpl_op_find_unique and qpl_op_rle_burst analytic operations
• Dropped support of zero compression: qpl_op_z_compress{16, 32} and qpl_op_z_decompress{16, 32}

Bug Fixes

• Changed accelerator dispatching to use lazy initialization with locks to ensure thread safety. Previous behavior might result in crashes on user's side when they fork a child process to submit job to the accelerator
• Fixed non-optimal Huffman Only compression when executing on Software Path
• Fixed incorrect mapping of accelerator status codes to library status codes which previously resulted in returning undocumented error to the user

Known issues/limitations

• Intel QPL cannot be built from direct downloadable files (.tar, .tgz) since it has submodules which are not included to the archives by GitHub during release creation
• Internal error code QPL_STS_INTERNAL_ERROR has been moved from error code 222 to error code 6. This could affect users having a hardcoded check for error 222
• On Linux libaccel-config.so must be placed in /usr/lib64/ to build and run Intel QPL, even if only the Software Path execution is used
