In version 5.2, plone tries hard to suppress the generation of a base element which Zope wants set. This makes the use of relative urls unreliable (they no longer work in all cases where Zope would set the base element). Why was this base suppression logic implemented?
Apparently, this has been introduced to fix "https://dev.plone.org/ticket/13705", but this url is no longer resolved. Is there an archive somewhere for the old tickets?
Maybe here are some pointers: https://web.archive.org/web/20140401051506/https://dev.plone.org/ticket/13705
Thank you. The given URL apparently describes PLIP 13705 which answers my question.
