#183478 alphabetizing now correct #184161 setting field as 'required' now works properly #215079 not sure if it was broken in the first place, but 'ratings' can be properly changed and checkboxes can be unchecked as expected #212624 hopefully fixed a views exposed filter thing #216821 again, not sure it was broken, but terms are properly shown/added the first time the node is saved #200786 new feature: restrict creation of top level branches #205093 new feature: restrict creation of branches #221028 i think the last two items cover this one as well #215170 changed how terms were saved to use native taxonomy functions which makes sure pathauto gets a hold of them properly #177988 new feature: can now add multiple terms at once still broken: single select of terms (radio button); see http://drupal.org/node/227306

| 484 | * Also, directly going to any taxonomy url will not include nodes so associated. |

| 486 | * Example use case: A vocabulary of interests in a nodeprofile node where you want your own search mechanism |
| 487 | * to sift and show what a user has permission to see, rather than the whole node. |
