The artifacts can be found on artifactory here with the code available on GitHub, as ever.

Let’s start with the biggest number: 150. That’s how many bug fixes, usability tweaks, and documentation improvements we’ve made since the release of Corda 4.0. Though few things in life are as certain as death, taxes, and a point release shortly after major software versions; Corda 4.1 brings all of the lessons learned during the development of Corda Enterprise 4.0 to the open-source community.

Version 4 of the Corda API continues to evolve

In Corda 4.1 you’ll find the core features of both Corda and Corda Enterprise are more closely aligned than past releases, making CorDapps testing in mixed-type environments easier than ever! We’ve learned some important lessons from Corda/Corda Enterprise 3.0, and we think Corda API version 4 delivers a stable, robust, feature-rich platform to drive your DLT needs from PoC to production; whichever flavour of Corda you’ve chosen.

Upgrading from Corda 4 to 4.1 should be relatively painless, and we strongly suggest all developers and users upgrade their nodes and apps as soon as possible to benefit from the past 3 ½ months of polish. For those appreciative of the theme we like to run through these things… that’s about long enough grow a whole tiger!!

It’s not flashy, it’s not packed full of new features, but we’re proud nonetheless to deliver you a whole lot of goodness and work with you all to deliver it. I, for one, cannot wait to see what the community builds with it.
