If so, upgrade your programs to TLS 1.2 or above as soon as possible. The minimum versions for common programming languages are as follows:
Java: TLS 1.2 can be manually enabled from 7u95, and is enabled by default from 7u131.
Python: 2.7.9, and 3.2 or later.
Node.js: v0.10.x or later.
C#: .NET Framework 4.5 and Mono 3.2 or later.
