Sakai 2.9.4 (and a note about Lessons with 2.8.x)


If you are running the Lessons that comes with Sakai 2.9.x, database upgrades are handled automatically. No special instructions are needed.


 If you install Lessons yourself, we recommend using the most recent tag. This is currently 1.4.2.  If you install it yourself, you need to be concerned about database schema updates.  We recommend starting once with auto.ddl on. That will handle most database updates for you. The exceptions are in the following files:

 If you are moving from a copy of lessons older than the 1.4.0 tag:

* simplepage.pre29-to29.sql

If you are moving to the 1.4.2 tag from any previous version, and are using mysql: 

* simplepage.for-2.9.2.sql [mysql only] 

If you are unable to use auto.ddl, see the README files in the Lessons source. It will explain how to generate a database update script to go between any two versions of the source.

For the convenience of sites running 2.8, we generate binaries for 2.8. See


Deprecations, Removals and Warnings





2.9.0Citations/Google Scholarretired
Google has discontinued Sakai support in Google Scholar with the new Google Scholar UI introduced earlier this year. This was confirmed directly with Google. For more information, see a sakai-dev post from May 2012:
For now, the problem can be fixed by adding a "sciui=2" parameter to the Google Scholar URL to force the old Google Scholar UI, but it's not clear how long Google will keep the old interface available.
2.9.0NeoChatdisabledNeoChat is a new feature in 2.9.0. We recommend leaving neochat disabled in a production environment until performance and usability tests are completed
