[cle-release-team] CLE 2.9.x/2.9.2 news: BasicLTI 2.1.0 upgrade (trunk/branch implications)

[Anthony Whyte]

The upcoming Sakai CLE 2.9.2 release will feature BasicLTI 2.1.0, a minor version upgrade that more fully implements IMS Global's LTI 1.1 specification. [1]   In addition, BasicLTI 2.1.0 provides enhanced administrator control over LTI placements and improved LTI-LessonBuilder integration.  Documentation for the LTI API extensions has also been improved and a complete API extensions test suite written in PHP has also been added  Not least, a good many bugs identified in earlier BasicLTI releases have been fixed including several minor security-related issues.  According to Chuck Severance, BasicLTI 2.1.0 effectively completes LTI 1.1 support in the CLE and lays the foundation to begin support for building LTI 2.0 [2].

As we ready the 2.9.x branch for the release of CLE 2.9.2 and BasicLTI 2.1.0 developers and deployers should note the following changes made to trunk, the 2.9.x branch and the 2.9.x-all: branch:

CLE 2.9.x branch
As of r122647, the 2.9.x branch binds to BasicLTI 2.1-SNAPSHOT, replacing 2.0.2-SNAPSHOT.  BasicLTI conversion scripts have also been added to both trunk and 2.9.x /reference/docs/conversion 2.9.1->2.9.2 conversion scripts.

CLE 2.9.x-all branch 
As of r122648, the 2.9.x-all branch's svn .externals file has been updated to include the BasicLTI 2.1.x branch code in the checkout.  If you utilize this branch for development you should delete the /basiclti module code (versioned 2.0.2-SNAPSHOT) and then perform an svn update in order to refresh your check out with BasicLTI 2.1-SNAPSHOT code.

cd 2.9.x-all
