I see - sounds good for updating the version in apros. Bring it up to the last release of jquery-xblock, and locally you can cherry-pick this commit to have the resources sent by the LMS with the hash format: https://github.com/edx-solutions/edx-platform/commit/de88e5adeab2718548dfd858d6d52e5520e2f452 (branch https://github.com/edx-solutions/edx-platform/commits/xblock-external-ui ). I'm going to push it to the LMS too, so you only need to care about apros for now.
