A fresh batch of Elgg releases are now available. The new 2.2.0 has some handy, new developer features.
Though I made a 2.1.3 release, 2.1 releases are no longer supported. Users should upgrade to 2.2.0 as soon as possible.
1.12.12 is also released for 1.12 users.
Security issues should be reported to email@example.com!
