Dear Sir,

For one of our project we are currently using Intel MKL(Maths kernel library)  ver 10.0.4 on Redhad enterprise Linux 7.2 distribution.

where as we found latest version on site: https://software.intel.com/en-us/articles/intel-math-kernel-library-rele...

is MKL -2019 update4

please let us know what chronology (sequence) of version History (from initial version to latest)

Also, please let us know, way to find out the differences in versions 10.x.x and MKL-2019.update4
