Has AMQ resolved the selector issue?

Hi all, It's well known that AMQ has the selector issue which causes consumers with selector to subscribe messages they are interesting in can not receive any messages dispatched from broker.
It's usually to get into this trouble when a topic has many durable subscriptions with selector enabled.
I donot known the latest release of AMQ 5.5.1 has resolved the problem or not?

The issue (with sparse selector match) still exists as selectors are
only run on messages in memory. It is possible to configure the
maxPageSize to ensure that all messages live in memory. But for memory
constrained systems, the problem still exists.
Virtual topics can provide an alternative solution to durable
subscribers with selectors.
