+The input is matched using the default predicate, which means it searches both entry content and outline paths.  This is helpful when a collection of links are kept in Org files: rather than having to first visit the entry containing the desired link, then locate it within the entry, and then open it, the user can simply select the link and open it directly.  For example, if an entry with the heading =Emacs= contained a link named =mailing list=, one could search for =Emacs list= and open the link to the mailing list directly.

+----------------------
+
+This command finds links in entries matching the input query and offers
+them for selection; the selected link is then opened with
+‘org-open-at-point’.
+
+   The input is matched using the default predicate, which means it
+searches both entry content and outline paths.  This is helpful when a
+collection of links are kept in Org files: rather than having to first
+visit the entry containing the desired link, then locate it within the
+entry, and then open it, the user can simply select the link and open it
+directly.  For example, if an entry with the heading ‘Emacs’ contained a
+link named ‘mailing list’, one could search for ‘Emacs list’ and open
+the link to the mailing list directly.

+     not yet comprehensive, e.g.  a query that depends on the specific

+     timestamps were not matched at all.  See #237

+     (https://github.com/alphapapa/org-ql/issues/371).  Thanks to Ihor
+     Radchenko (https://github.com/yantar92).)
+   • Timestamps with day-of-the-week abbreviations are matched more
+     flexibly (allowing, e.g.  a period in French locales).  (See #429
+     (https://github.com/alphapapa/org-ql/discussions/429), #432
+     (https://github.com/alphapapa/org-ql/issues/432).  Thanks to

+     ‘org-ql-view’ buffer to search the buffers which contributed to the
+     agenda/view buffer.
+   • Command ‘org-ql-find-path’, which searches outline paths in the
+     current buffer.
+   • Command ‘org-ql-open-link’, which finds links in entries matching
+     the given query, and opens the selected one with
+     ‘org-open-at-point’.  (This is helpful when a collection of links
+     are kept in Org files: rather than having to first visit the entry
+     containing the desired link, then locate it within the entry, and
+     then open it, the user can simply select the link and open it
+     directly.)
+   • Items in ‘org-ql-view’ buffers now include the ‘org-category’ text
+     property, like Org Agenda buffers, which allows grouping with
+     ‘org-super-agenda’’s category-related selectors.  (#363
+     (https://github.com/alphapapa/org-ql/issues/363).  Thanks to
+     Gabriele Mongiano (https://github.com/kofm) for reporting.)
+
+   *Fixes*
+
+   • Predicate ‘property’ correctly uses the value of
+     ‘org-use-property-inheritance’ when not specified.  (#346
+     (https://github.com/alphapapa/org-ql/pull/346), #356
+     (https://github.com/alphapapa/org-ql/issues/356).  Thanks to Bram
+     Schoenmakers (https://github.com/bram85).)
+
+   *Compatibility*
+
+   • Emacs 27.1 or later is now required.
+   • Org v9.7’s ‘org-element’ API changes required some adjustments.
+     (#364 (https://github.com/alphapapa/org-ql/issues/364).  Thanks to
+     several users for reporting, and to Ihor Radchenko
+     (https://github.com/yantar92) for his feedback.)

+6.1 Copyright assignment
+========================
+
+While Org QL is currently distributed in MELPA, it’s intended
+(https://github.com/alphapapa/org-ql/issues/409) to merge Org QL into
+Org mode.  When that happens, it will become a part of Emacs and Org,
+and therefore cumulative contributions of more than 15 lines of code
+will require that the author assign copyright of such contributions to
+the FSF.  Authors who are interested in doing so may contact
+assign@gnu.org <assign@gnu.org> to request the appropriate form.
