We have released Picard 2.2.3 as a maintenance release to address a couple of bugs. The new release is available for download on the Picard website.
More details in our blog post:
Meanwhile development of what will become Picard 2.3 is also progressing. There is no schedule yet for this next feature release, but if you are curious you can look at the tickets currently tagged for the 2.3 release to see what is currently planned and partly already done. No promises though that any individual feature will make it into the release, but we’ll see how this goes. I’m pretty sure there will be a beta release this time.
