Release v0.5.7 contains the following changes:

* Tidy up of debug messages in the memory driver test app.
* Add EPOLLET flag when adding fd to epoll to support upstream driver
* Correct calculations of available slab space in qae_mem_utils.c
* Tidy up parsing for LimitDevAccess setting
* Documentation update for release of OpenSSL_1_1_0

Release v0.5.6 contains the following changes:

* Remove unnecessary parenthesis to fix style of switch() statements
* Add missing #include to fix compilation warnings.  Also fix the indentation of other #include lines
* Code changes required by changes in constness of some function parameters in OpenSSL-1.1.0.
    - Make DSA_SIG and ECDSA_SIG getters const
    - Constify the parameter getters for RSA, DSA and DH
* Fix for the issue caused by RSA decrypt call to engine now passing RSA_NO_PADDING instead of RSA_PKCS1_PADDING and the padding removal being handled in the calling function. This was not supported by the QAT Engine. The issue was introduced by the following OpenSSL commit:

    5b8fa431ae8eb5a18ba913494119e394230d4b70
    Make RSA key exchange code actually constant-time.
* Fix to allocate r/s for DSA_SIG and ECDSA_SIG in the engine code.  This change was necessary due to the following OpenSSL commit:

    8cc44d970ced1004db0727d7a7b3e2709c442e55
    Don't allocate r/s in DSA_SIG and ECDSA_SIG.
* Change to the QAT engine build process such that the default QAT engine shared library install directory is  </path/to/OpenSSL/install_directory>/lib/engines-1.1. This change was necessary due to the following OpenSSL commit:

    b2de11c58b57e7f0d58c6f8a1d4177705650647e
    Versioning engines default location: the Unix case.
* Fix valgrind's memcpy warning.
* Fix debug functions for common memory driver
* Fix missing cleanup of engine specific error strings
* Update README.md to document OpenSSL speed bug

* Support for event driven mode with Upstream driver

* Fix config file for the latest version of Upstream driver

Release v0.5.4 contains the following changes:

* Adding updated Autotools dependency files
* Fix for the Autotools timestamp issue
* Support for building the Memory Driver under Ubuntu

Release v0.5.3 contains the following changes:

* Various Fixes for the Autoconf based installer
* Fix compilation error when PRF is disabled
* Added configuration files for the Upstream driver
* Remove Makefile link dependencies that are no longer required
* Remove code for Zero Copy Mode

Release v0.5.2 contains the following changes:

* Fix support for building with the Common Memory Driver
* Fix issue where Engine Initialization Messages can fail due to a NULL instance.
* Add Support for Upstream Intel Quickassist Technology Driver
* Fix to checking return status of qat_ecdh_compute_key call
* Change to use an Autotools generated configure script for installation
* Update to documentation - make depend order.
