+## v0.0.22

+- Fix shell completion with multiple NetBox instances: typing a hostname without an instance prefix (`fsn1-bx1<Tab>`) found nothing in bash and zsh, because only `prod/…` was offered. Hostnames that are unique across all instances are now offered without the prefix; connecting to them still checks every instance for ambiguous names.
+- zsh also accepts instance-qualified matches for the typed hostname, so names that exist in several instances are offered as `prod/…` and `stg/…`.
+
 ## v0.0.21
 
 - Ship a zsh completion script built for large caches: 5000 hosts complete in under 0.1 s instead of hanging for seconds with Cobra's generated script.

 Completions are served from the local cache — no network request on every `<Tab>`.
+With several NetBox instances, a hostname that exists in only one instance is
+completed without the instance prefix (`web01`); names that exist in several
+instances are offered as `prod/web01`, `staging/web01`. In bash, type the
+instance prefix for those; zsh and fish offer them for the hostname alone.
 The zsh script that `netssh completion zsh` prints is built for large caches:
 5000 hosts complete in well under a second. To limit the number of hostnames
 offered, set `completion.max_results`.
