Release 0.65 has arrived and oh boy, is it awesome. First off, in case you have missed the previous release notes and announcements: Starting with this release, Home Assistant has dropped support for Python 3.4. The minimum supported version is now Python 3.5.3. If you are on Hass.io or Docker, you’ll automatically be running the latest and greatest. If you’re on an older Hassbian installation or did your own Linux setup you’ll need to upgrade to at least Python 3.5.3.
Naming entities
With the introduction of the entity registry in 0.63, Home Assistant is making sure that the same devices always receive the same entity IDs. This release is taking it a step further by allowing users to change the name of a device from the frontend. Changing the name will be instantly applied and overrides whatever name the device is given by the integration. If you want to switch back to the name from the integration, set the name to blank.
This feature is, just like the entity registry, only available for integrations that provide unique IDs for their entities. Adding this to each integration is still a work in progress.

Filter sensor
The filter sensor is a new 2nd order sensor by @dgomes: it will consume data from a sensor entity and apply filters to it. For the initial implementation it comes with Low-pass, Outlier and Throttle filters. Expect more to be added in the future.
sensor:
- platform: filter
name: "filtered realistic humidity"
entity_id: sensor.realistic_humidity
filters:
- filter: outlier
window_size: 4
radius: 4.0
- filter: lowpass
time_constant: 10
precision: 2

Light Group
We have had some discussion lately and realized that our current group component is very limiting. Extending it would probably lead to more confusion so we’ve decided to take a new approach: groups that are designed to be part of a specific component. The first one in this series comes at the hand of @OttoWinter: the group light (docs).
The group light creates a single light inside Home Assistant that is representing a group of lights. All commands will be forwarded and the state is a combination of all the lights.
light:
- platform: group
name: Cool Light Group
entities:
- light.amazing_light
- light.foobar
- light.sun
HomeKit
HomeKit got some more upgrades. We’ve added support for temperature sensors in Fahrenheit, alarm systems, switches and thermostats. Just a few releases more and we should be able to cover it all.
Optional words for the Conversation component
The conversation component has always been a great introduction to controlling your house by voice. There is no hotword detection or powerful language engine behind it, but it gives a great intro to what is possible. Starting with this release, it will get a little bit more powerful with the introduction of optional words. To mark a word optional, wrap it in square brackets: Change the light to [the color] {color}.
