 # tamRgo 0.0.0.9007
 
 * Used concept of 'XP freeze' at a certain age (21); chance of being unalive after this is dependent on that freeze value and the number of days since that age was reached (towards #23).
-* Adjusedt passive XP accumulation (#24).
-* Alerted user on level up.
+* Adjusted passive XP accumulation (#24).
+* Added alert for user when pet levels up.
 * Created internal dataset as `internal`, containing `$sprites` and `$constants` for a single source of truth on level up thresholds, age for XP freeze, etc.
+* Added a chance-based minigame to the `play()` function.
+* Corrected and update exported-function documentation.
