+# Pending Changes
+
+This is a list of pending changes to the Zed extension API that require a breaking change.
+
+This list should be updated as we notice things that should be changed so that we can batch them up in a single release.
+
+## vNext
+
+### Slash Commands
+
+- Rename `SlashCommand.tooltip_text` to `SlashCommand.menu_text`
+  - We may even want to remove it entirely, as right now this is only used for featured slash commands, and slash commands defined by extensions aren't currently able to be featured.
