+The websocket API provides a sensor that will keep track of the number of current connected clients. You can add it by adding the following to your configuration:

 - __Z-Wave__ - The usb_path in configuration.yaml now overrides config entry usb_path. This is potentially a breaking change if people have a stale usb_path setting in configuration.yaml that's no longer accurate. This should help reduce the number of people that need to manually edit the storage/core.config_entries file if their usb_path changes. ([@cgarwood] - [#22038]) ([zwave docs])
 
 - __iOS__ - Improves the text description of ATTR_BATTERY_STATE_UNPLUGGED from Unplugged to Not Charging as many new iOS devices now use Wireless charging and there is no concept of "Plugging In". This is potentially a breaking change if you have automations making use of "unplugged". ([@FattusMannus] - [#22152]) ([ios docs])
-- __Iliad Italy__ - __Removed__ - This was removed because it uses webscraping and Iliad is conducting a/b testing on their web pages, making it  not stable for use in production.  ([@eliseomartelli] - [#22175]) ([iliad_italy docs])

 - __Netgear lte__ - The previous three components (network, notify, and sensor) now fall under one netgear_lte component. Check the [updated documentation](https://www.home-assistant.io/components/netgear_lte/) for more information. ([@amelchio] - [#22105]) ([netgear_lte docs])
-- __API streams sensor__ - __Removed__ -  This sensor component was designed to count connected front-end clients. However, it depended on the implementation details of other components, and has therefore been broken since 0.80, so it has been removed. The replacement sensor is now the [websocket_api sensor](https://www.home-assistant.io/components/sensor.websocket_api/), which does basically the same thing apart from the rename.

 - __Public Transit (GTFS)__
   * The state for this sensor component was a countdown in minutes. If the next departure was in a few hours, this number became quite large and a tad harder to rapidly calculate mentally (463 minutes anyone?). The sensor's state output has been changed from minutes to an ISO 8601 UTC timestamp, which allows the UI to interpret the state as needed. ([@renemarc] - [#21053]) ([gtfs docs])
   * Sensor updates were running many database queries to populate attributes, on top of the bus schedule queries themselves. This is doubled with two sensors. That led to a lot of slowdowns for everything else when using an SD card! Considering that some data never changes (agency, routes...) and that others like departure times are good until invalidated, now we fetch such metadata at first and then only when relevant changes do occur. GTFS sensor attributes are now named using the standard snake_case format. ([@renemarc] - [#20966]) ([gtfs docs])
