Major snapshot release

Major snapshot release image

It has been a while since the last snapshots and alpha releases have been published. This release sets a milestone to our upcoming BETA release.

Wow, this has been a while. Let's first start with the primary reasons for the delay.

  1. Last year we refreshed the web interface and replaced the jqwidgets library asap. This change gave us a lot of improvements, but did not provide a good interface to continu building on. With a fair amount of emails requesting a lighter and more clean interface, reason one was created.
  2. The server was given the ability to serve multiple protocols at the same port like websockets and http on te same port, this was done for both secure and non secure connections, the secure connections even got the http2 and SPDY protocol added on the same port. SPDY is going to retire in favor for http2 and apple announced only secure will be allowed in the future. Cleanup was required, reason 2.
  3. Because the server moved to http2 (with http 1.1 fallback), the clients needed to get updated to take advantages of this resulting in faster data retrieval, reason 3
  4. The server only allowed updates when having a persistent connection using raw or websockets, this made the background service of the android app a very expensive one. A solution for this was needed, reason 4,
  5. Etc. some etc, and a little but more etc.

Because of the above 5+ reasons it took a while to release of a new snapshot kept us really busy, especially the new web interface (which cost weeks and weeks) but here it finaly is. My guess is that you are more interested in what has changed. So to make a long story short, the change logs.


If you are updating, you need to update your the init script and for the users:

  1. Remove assigned mobile devices,
  2. Save the user which had the mobile device asigned,
  3. Re-asign the mobile devices to the user,
  4. Repeat for every user.

The above is not needed for fresh installations.

The above change log is quite abstract as every update consist of a large set of small updates. The largest set of small updates are for the web interface which includes a lot of fixes and updates. Next to the web interface a lot has been done on server internals. With this update we will be able to implement features a lot faster.
