| <tt>helper.GetContentPacks</tt>
| →
| <tt>helper.ContentPacks.GetOwned</tt>
| Identical usage.
|-
| <tt>helper.CreateTransitionalContentPack</tt>
| →
| <tt>helper.CreateTemporaryContentPackContentPacks.CreateTemporary</tt>
| Identical usage. (This was a temporary method for the transition to [[Modding:Content packs|SMAPI content packs]], but a few mods have permanent use cases for it.)
|-
| <tt>assetData.AsDictionary<T, T>().Set</tt>
| →
| <tt>assetData.AsDictionary<T, T>().Data</tt>
| The <tt>Set</tt> methods caused a lot of confusion and were of limited usefulness. You can access the dictionary directly using the <tt>Data</tt> field instead.
