When using links for fluid widgets (like Paginator widgets) it is not possible to disable the cHash calculation.
A new argument
useCacheHash for the
<f:widget.link> and the
<f:widget.uri> ViewHelpers has been added
to re-enable the previous behaviour.
Additionally, using cHash and addQueryString is counterproductive for deterministic caching purposes,
thus this combination should not be set by TYPO3 core by default.
