OpenLabyrinth v3.2 released

We just kicked out a new minor version release. For those of you who are running your own OpenLabyrinth servers, you can download this new version from

For most of us who don’t have to deal with that level of geekiness, you can simply check out the new features at – you may need a login to see many of the features that are oriented towards case authors.

OpenLabyrinth bookmarks return

In OpenLabyrinth v2, there was a useful little feature where you could place a bookmark anywhere in a lengthy case and then return to that same point earlier. This feature had lain dormant in OpenLabyrinth v3 for some time but now, good news…

Bookmarks are back. If you click the [bookmark] button on the right side of a case node, you can leave a bookmark in the case, to which you can return later. And, as an enhancement over the old version, now any scores that you had accumulated to that point are now restored. If you take a look at the Session Report at the end of the case, your data and pathways from the two parts of the case are merged into a single session.

This will be particularly useful for our longer cases. Try it out and let us know what you think.

A few small things to note when using Bookmarks:

1. This only works for registered Users (the system has to know who you are to maintain continuity between such sessions).
2. When you click on the [bookmark] button, don’t expect any fancy bells & whistles to go off. OLab just quietly notes your current place.
3. To resume a bookmarked case, click on the menu Labyrinths | My Labyrinths and then scroll or search through that list. Any case where you left a Bookmark will have an orange [Resume] button, as well as the usual green [Play] button.
4. A User can only leave one bookmark per case but can leave bookmarks in as many cases as they like.
5. When you Resume a case from a bookmark, the bookmark is immediately cleared.

As a case author, if you want to prevent use of Bookmarks, simply remove the [bookmark] button from the Skin for that case.




Upcoming server changes

We have a few changes coming over the next 2-3 weeks in our server setups and apologize for any inconvenience caused.

The development box at is running on a Dell server that is now getting a bit elderly. We will be moving it to a virtual server farm for better reliability and capacity. And speaking of capacity, the disk is rather full as well so we will be adjusting this as well.

[Update on disk space: I found a whole pile of old unneeded files and deleted them. Much more disk space now. I hope we also see a small improvement in OLab3 performance.]

So those who are doing dev work at demo.olab3 might find that server down intermittently during this changeover.

For our production servers, we will take a more formal and smooth migration approach with proper announcements.
