[Building Sakai] OAE 1.4.0 status update

[Anthony Whyte]

The next release of OAE 1.x is nearing completion and quick update is in order.   This release provides a set of UI performance optimizations, caching improvements as well as fixes to a number of slow queries.  A key goal is to reduce page load times as well as the number of requests currently required to assemble a page.  We've also made a number of other minor improvements (see highlighted ticket list below).  We hope too to include a number of accessibility fixes that are currently pending merge and being reviewed.  

Assuming QA proceeds as planned we should be in a position to produce a release candidate in the next week or so with a final release slated for mid-July.

Cheers,

Anthony
