 # Changelog
 
+## 1.0.16
+
+- Player rows include `user_id`, `user_name`, `online`, and keep
+  `device_ip_address` (Emby session `RemoteEndPoint`, host only)
+- `retrieve_player_list` accepts `users` (comma-separated include-list)
+  and `include_offline` (merge `GET /Devices` last-used owners)
+- Add-on options `player_users` and `player_links` feed a default
+  include-list and HA entity map (`ha_entity`, `ha_source`, `device_ip`,
+  `emby_device_id`)
+- New tool `resolve_media_player` for "play on the lounge": returns
+  HA entity/source plus `session_id` when live, or `wake_required`
+- Conversation Functions YAML and system prompt updated in DOCS.md
+
+### Potential breaking change
+
+- Player JSON grows `user_id`, `user_name`, and `online`. Re-paste the
+  DOCS.md Functions block to pick up `emby_list_players` parameters and
+  `emby_resolve_player`. Existing PlayNow calls are unchanged.
+- Empty `player_users` means no default filter (same listing as 1.0.15,
+  plus owner fields). Non-empty `player_users` hides other accounts even
+  when the model omits `users`.
+
 ## 1.0.15

-- Media & Emby: Never use execute_services for Emby. Use `emby_search` to find films, TV series, episodes, or music tracks. Use `emby_episode_list` to list or count a series' episodes (seasons via `emby_season_list`). Each episode item includes `premiere_date` (YYYY-MM-DD first air date) when Emby has that metadata; use it for airdate questions. Use `emby_list_players` to find active playback sessions, and `emby_playback_control` to send playback commands (PlayNow, Pause, Unpause, Stop, NextTrack).
