So here we have it - Infinispan 5.0 Pagoa has been released. This is a big, big release over 4.2.x, with over 45 new features (including the much more robust PUSH-based rehashing, XA recovery, smart L1 invalidation and virtual nodes) and over 30 bugs squashed, including several critical performance and stability related ones. Major new programming models are supported too - from Spring and CDI through to OSGi, map/reduce and distributed code execution.
Pagoa has gone through over six months of development, the first alpha being made publicly available in December 2010, and 8 whole release candidates since the end of April this year. This is the most stable, fastest, feature-rich version of Infinispan to date. Pagoa has been integrated in other products, projects, frameworks and services - including the lightning-fast JBoss AS 7 - and we expect to see much, much more in this regard.
Pagoa really is a community-centric release. I've seen loads of participation, from users, system integrators, extension-authors, researchers and academics, framework authors, and PaaS providers. This participation has taken the form of providing feedback and bug reports through to profiler analysis; from helping with documentation and demos through to contributing major new features; from suggesting ideas and improvements to participating in detailed design meetings. It is this participation that really helps Infinispan grow and mature, and at the same time innovate, taking us one step closer to becoming the best damn data grid out there.
So, a big thank you to everyone who participated, this really is your release.
As usual, download the release, provide feedback, read through the detailed changelog. And check out our brand-new documentation site too!! :-)
Finally, in other news, I recently blogged about Brahma, the codename for Infinispan 5.1. Yes, work has already started here, expect Brahma to be a real firecracker. Check out the post, vote for your most desired features. Brahma will also form the basis of Red Hat's Enterprise Data Grid product, which was announced in May. You'll finally have a fully supported open source data grid!
