 ## Install
 
 ```
-commons @ git+ssh://git@git.rethinkstudios.io/rethink-public/commons.git@v0.2.1
+commons @ git+ssh://git@git.rethinkstudios.io/rethink-public/commons.git@v0.2.3
 # async address/geo lookups (fetch_ip / ip_location / fetch_location) need the extra:
-commons[addr] @ git+ssh://git@git.rethinkstudios.io/rethink-public/commons.git@v0.2.1
+commons[addr] @ git+ssh://git@git.rethinkstudios.io/rethink-public/commons.git@v0.2.3
 ```
 
 The base install pulls **nothing** (stdlib). Only `commons[addr]` adds `aiohttp`, and
 only for the geo lookups — the pure `commons.addr.ip` utilities ship in base.
 
+Drop the `@v0.2.3` suffix from the line above to install the latest unpinned.

 ## timing
 
 Unix ints stay the storable value; datetimes are produced on demand in whatever
