Are you sure you're talking about features that appear in released
versions of EPICS base? TTBOMK the support for double-buffering of
arrays only appears in the unreleased 3.15 branch of Base, although
I'm going to guess that Michael Davidsaver's Debian packages may have
a back-port of that that functionality to 3.14.
