Blog post about Let's Encrypt root certificate expiration and OpenSSL 1.0.2

[Tomas Mraz]

I've written a blog post to explain the situation with the old Let's
Encrypt root certificate expiration which will happen on 2021-09-30 and
the behavior of OpenSSL 1.0.2 with that root certificate.

Please read, if interested:
