[keul]
- ``icon:`` and ``title:`` features also for internal links
[keul]
- Error migrating from 0.7: the catalog was created inside the
``portal_setup`` tool!
[keul]
- Added a new "refresh catalog" command on tables
[keul]

This prevent infinite caching of computed columns
[keul]

[keul]

----------------

Plone form labels

[keul]

- Fixed a problem with link-like columns and cache. Do not return object absolute_url
because a backend URL could be cached. Instead use the *resolveuid* URL and run
table through portal_trasform when in view.
Drawback of the approach: when editing the table's URLs still use *resolveuid*
[keul]
