Hello, Parser used to have a hard-coded list of keywords that should be parsed, namely "TITLE", "DATE" and "AUTHOR". This is no longer the case since export back-ends can explicitly introduce new parsed keywords (e.g., "SUBJECT" in "ox-koma-letter") with a `parse' behavior (see `org-export-options-alist').
Note that if a keyword is parsed, its associated property (with prefix "EXPORT_") will be, too. Macros are now expanded in any of them. As a side-effect, `org-element-context', which shouldn't depend on back-ends loaded, cannot return objects within "TITLE", "DATE" and "AUTHOR". This shouldn't affect `org-open-at-point', which now follows links within all keywords. Regards, -- Nicolas Goaziou 0x80A93738
