Ben, we apologize for the lack of notification, we felt our customers would want to install all of the updates at the same time so where going to send an email when all updates where completed. We did not want flood the email boxes of our customers. we have been announcing updates here in the forums as well on on our Facebook page and Twitter feed. In response to your message, I have asked our marketing manager to send individual email updates.
Also, please see this response from Ray to one of your other posts:
We didn't want to crowd our customer email boxes with alerts and messages since the updates are coming out so quickly and our plan was to make the announcement early next week as soon as all of the updates have been pushed live. So far we have released fixes for Data Bridge and mySQLi server behaviors. Our plan is to get eCart out today, and Design Extender and free tools tomorrow so that we can send out the announcement over the weekend.
It wasn't an act of arrogance to not announce, it was a decision to not annoy people with too many emails and based on the concept that most of our customers will want to upgrade everything at once. Many have downgraded and are still using CC 2014 in the meantime and wouldn't want to upgrade to 2014.1 until all of the extensions have been updated.
We have been making the announcements in the forums and social media channels in the mean time so that active customers can see the progress if they are interested.
I further apologize if this was the wrong decision for you. This has been a difficult and unexpected problem that has caused us some frantic reworking of how our extensions activate over a short period. We are doing our best to correct the problem in a timely manor and it is our highest priority.
