Hello from the staff at Let's Encrypt.

On September 30, there will be a change in how older browsers and 
devices trust Let's Encrypt certificates, resulting in a minor decrease 
in compatibility. If you run a typical website, you won't notice a 
difference. Devices and browsers running up-to-date software will 
continue working fine, and we've taken steps to make sure the vast 
majority of older devices will too. If you run a large website, or need 
to support less common software (particularly non-browser software), 
you'll want to read about the details at:

In either case, no action is required from you. We're letting you know 
so you can provide answers to any questions your site visitors may have.

Here is a sample hostname from one of your current Let's Encrypt 
certificates:  team.pld-linux.org 

Since 2015 we've served the world with 1.6 billion free certificates, 
each one providing security and privacy to people on the Web. It's work 
that's 100% funded by charitable donations since we are a nonprofit. If 
your company is interested in sponsorship, please email 
sponsor at letsencrypt.org. If you can make a donation, we ask that you 
consider supporting our work today: https://letsencrypt.org/donate/ 
Thank you.
