 ## Switch
+  * Put back support for switch creation with packages argument and
+    `--packages` option with cli 2.0, and a specific error message for cli 2.1
+    [#4853 @rjbou - fix #4843]

+  * [BUG] Fix `set-invariant: default repos were loaded instead of switch repos [#4866 @rjbou]

+  * When inferring a 2.1+ switch invariant from 2.0 base packages, don't filter out pinned packages as that causes very wide invariants for pinned compiler packages [#5176 @dra27 - fix #4501]
+  * Really install invariant formula if not installed in switch [#5188 @rjbou]
+  * On import, check that installed pinned packages changed, reinstall if so [#5181 @rjbou - fix #5173]
