The big community news of this month was the release of Jakarta EE 9.1! The Eclipse Foundation brought out Jakarta EE 9.1 Platform and Web Profile specifications and related TCKs - the first release since the breaking namespace change to jakarta. We've rounded up our articles & announcements on this subject below - and watch this space, as Payara Platform is very close to launching our own Compatible Implementation.
We also released the results of our Payara Platform Survery 2021 . Read in fullhere, including what we've learnt about the infrastructure you are using with the Payara Platform, what features you want to see, and our findings on how our users are adopting MicroProfileAPIs and new Jakarta EE versions.
We're already using the results of the survey to shape content that responds to recurring issues users are encountering. See Rudy'sblog on why you might be finding Payara Server slow and an easy fix you may not have tried, as issues with deployment speed was a common theme in our survey results.
As well as Payara's own content, the 'Monthly Catch' also includes our pick of the best from Java EE/Jakarta EE, MicroProfile, Java SE and DevOps influencers and authors this month, and wider industry news. We hope you enjoy, and make sure you are following us onLinkedIn and Twitter, and signed up to our blog, to get this content as it comes!
