Sakai 10.4 Testing Overview
Re-testing merged Jiras
All issues that were merged into 10.x, had been tested in trunk before merging. Re-testing in the 10.x branch is another great way to prevent regressions and ensure the functionality is working as intended. See the list of 10.4 fixes. Use the Google doc to sign up.
