<h2 style="font-family: Times New Roman; font-weight: normal;">getAllStatements does not make a copy of returned values, getBestStatements does.</h2>

==== Background ====
The functions <code>getAllStatements</code> and <code>getBestStatements</code> are similar in behaviour but one function returns a list of direct Property-values whilst the other returns a copy of the list of Property-values.

==== The Problem ====
Direct values can be edited on the native Wiki page where the function <code>getAllStatements</code> has been invoked. If a returned property-value was changed and then the function was invoked again, this new value would be temporarily altered.

==== The Solution ====
Changing the <code>getAllStatements</code> behaviour of how values are returned to match <code>getBestStatements</code>, returning a copy of object values rather than directly returning them. This prevents the values from being temporarily altered from the native environment they are being invoked from.

==== Next Steps ====
* Logic of <code>getAllStatements</code> changed to behave as <code>getBestStatements</code> in <code>([[mw:MediaWiki_1.44/wmf.2|1.44.0-wmf-2]])</code>, deployed to all Wikis by 07.11.24.
