 ### Bug fixes
 
+* export: No longer export duplicate entries in the colorings array, a bug which has been present in Augur since at least v12 [#719][]. [#1218][] (@jameshadfield)
+
+* export: In version 22.0.0, some configurations of export may have resulted in the clade coloring appearing last in the Auspice dropdown rather than first. This is now fixed. [#1218] (@jameshadfield)
+
 * export: In version 22.0.0, validation of `augur.utils.read_node_data` was changed to error when a node data JSON did not contain any actual data. This causes export to error when an empty node data JSON is passed, as for example in ncov's pathogen-ci. This is now fixed by warning instead. The bug was originally introduced in PR [#728][]. [#1214][] (@corneliusroemer)
