serverextension is available in all servers, but it only does anything if the source is modified for it - But no...
This update had nothing to do with the ac_server directly - This was all about consistency in logging and extensibility of configuration and synchronization.
We also upgraded the underlying Operating System on all of the servers we host on.
To explain further - this update was really just a lot of things that had to be done for some time, that we had wanted to do for a while.
The big stuff is still on the way, but this was a major version swap for us, And now we will be much more prepared to implement other things to the system in the future - But we had to get to this point first...
We had a few noticeable impacts on day-to-day operation - and that is a failure so apologies from me on the little things we are still working out.
Ideally, you wouldn't ever notice any major changes, and I think for the most part, no one can really 'see' these changes directly besides the few of us working on it, but it has been a lot of work to achieve the current state, and so it was needed for us to share some of this.
It is much harder to post a demo or screenshot of Admin successes... We will just keep writing and hope eventually it will show in the code we develop... =)
EDIT: To try and demonstrate the level of awesome that you can't see - think of server configuration options - In AC - everything is traditionally done in a text file - The list of passwords and other options are written out in plain text - and then the server references the information in the text when it is called.
We are now organizing this configuration information in DATABASES.... Which may seem like overkill for the tasks of AC, but for a number of reasons, is actually incredible!
If you don't think that was any effort, try googling how to do it...
