 - New estimators and tests: :class:`~linearmodels.iv.model.IVJIVE`, first-stage rank
   tests, a centered J test, the Hausman and Pesaran CD tests for panel models, and panel
   models that only have effects.

+- Many technical corrections change the numbers that that were produced in 7.0. The most important of
+  these include changes to the default bandwidth of the kernel estimators of ``IVGMM``, ``IVGMMCUE`` and
   ``IVSystemGMM``, the Fama-MacBeth p-values and the weighted panel and system models.

+  See :ref:`changes-alter-rubric-target`.
+- Increased reliability of weighted estimators including testing post-estimation statistics
+  for correctness with weights.
 - Inputs with labels must have the same index as ``dependent`` (or as the first input
   with labels) in every estimator, and input of the wrong type now raises a clear
   ``TypeError`` or ``ValueError``. See *Backward-incompatible changes*.
