According to the Microcode Revision Guidance Guide document published by Intel, the development of updates fixing Spectre vulnerability has been officially stopped.In the version of the document dated April 2 the development status was indicated as "stopped". Previously, in the corresponding columns were either "planned" or "pre-beta. However, this does not apply to all of the company's devices. The company representatives explained their decision by the fact that the devices based on such processors are outdated and have very little commercial support. In addition, most systems using these chips work in "closed mode". This means that they are less vulnerable to attacks using the Spectre vulnerability.
