We just released op v0.9.0. There are quite a few internal changes but also some new commands/options. Specifically:
op addwas replaced by
op add userand
op add group, with the latter now allowing to add groups to vaults. Similar for
op get documentgot an
--outputoption to write the contents of a document directly to a file. This was added to work around shell output redirection issues.
See the download page for more information. Let us know how it goes!
