the ExoMol database for other very extensive line lists in future releases. At present these data are not included in the database.

NaCl
----

The original NaCl ExoMol line lists of Barton [[*et al*]{}]{} [@jt583] computed using [Level]{} have been truncated by removing transitions with $\Delta v
\geq 8$.

KCl
---

The original KCl ExoMol line lists of Barton [[*et al*]{}]{} [@jt583] computed using [Level]{} have been truncated by removing transitions with $\Delta v
\geq 12$.

PN
--

The original PN ExoMol line lists of Yorke [[*et al*]{}]{} [@jt590] computed using [Level]{} have been truncated by removing transitions with $\Delta v
\geq 6$.

AlO
---

A number of ExoMol users pointed out that the vibrational labels used in the original AlO line list were not the best ones. Our analysis of AlO state lifetimes [@jt623] reinforced this impression. The `.states` file has therefore been updated with revised vibrational state labels. We note that these labels are only approximate quantum numbers and this change should not affect any results obtained with the line list.

H$_3^+$
-------

The H$_3^+$ line list of Neal [[*et al*]{}]{} [@jt181] (NMT) is the oldest in the ExoMol database. While it has continued to demonstrate its accuracy
