Thank you! JDK 18 Early Access build 20 is now available

[Rory O'Donnell]

Hi Oleg,
 

Thank you.

I'm retiring at the end of November 2021, it's time to spend more time with the family.

We started the Quality Outreach back in October 2014.  We now have 170+ projects participating.

Thank you for taking the time to provide Testing feedback , excellent bugs and support throughout

the last seven years.

It's been a pleasure working with you. I am delighted to say that the program will continue

with the support of the Java DevRel Team, with David Delabassee as your contact. David has

been assisting with on-boarding new projects for the last couple of years.

All the best, Rory
