The big news from this month was the General Availability release of Jakarta EE 9 on November 20th, moving to the jarkarta namespace once and for all. This will be followed by an official release at the Eclipse Foundation's JakartaOne Livestream on December 8th - at which our Founder Steve Millidge is a key speaker. You can register to attend here.

It's also been a month of exciting news for Payara as a business, as we've extended our partnership with Azul Systems and taken key steps towards beta testing of our exciting Payara Cloud project, all alongside our regular monthly platform release. We've also been excited to see Payara used as examples in Community materials such as Otávio Santana, Geovanny Mendoza, and Aristides Bravo's new Jakarta EE guide, in various learning materials and blogs, and in a Microsoft tutorial!
