issue2551353 - Add roundup-classhelper for 2.4.0 release Changes to the classic template are not done yet. Still testing. This commit has document updates and changes to rest.py. rest.py: add /rest/data/user/role endpoint to core so the user doesn't have to add the /rest/roles endpoint via interfaces.py. It will only send roles for a user with Admin role and there is no way to override this currently. acknowledgements.txt: Added members of team3 to other contributors. Specified for all other contributes what they worked on. upgrading.txt: added classhelper section and basic template change directions. Linked to admin_guide for full directions. admin_guide.txt: documented install, translation, troubleshooting, config etc. user_guide.txt: added section on using the classhelper. Added reference to section earlier in the doc. Added image for section.
