OK, we think we're going to delay the release to next week now. We made the call because of the potential to include a cool extra feature that we think may benefit a cross-section of users. This is the ability to have Quark produce small 'baked' JARs containing only the executable Java classes and an entry point to a CAL function of type [String] -> () i.e. a main function taking string arguments.
I use the term "baked" above, because such JARs will not include a Workspace with the metadata necessary to be able to use the contents dynamically (such as in the many cases where we use Quark as a functional metaprogramming library for Java, typically creating transient functions under application control). However, this is great for writing straightforward apps and utilities. Being small and having much less metadata to load up to support dynamic programming means that startup time is drastically improved too with this deployment model.
So, hopefully we'll be able to dot the I's and cross the T's on this feature for next week, and if it makes it into the next revision then we will probably badge it as Open Quark 1.5.
