Gary D. Gregory commented on COMPRESS-705:
------------------------------------------
Hi [~jonesbusy]
Yes, there is definitely a release planned as soon as possible. There are just
a couple more items of housekeeping that we need to work on. It is on my
priority list but we have fixes in other components that sometimes get in the
way.
Thank you for your patience!
