## Improved stability and performance, and Python 3.10
{% details "TODO" %}
The quest to improve the performance of Home Assistant continues. For many
releases, [@bdraco] has been analyzing every single aspect of
Home Assistant and manages to make it faster every single release.
- Improve on story
- Spelling/grammar
- Something about start up reliability improvements
- Make it more to the point?
- Maybe split YAML from JSON
Usually, we have a section at the end of our release notes informing you
about the performance improvements made. The improvements in this release,
however, are a big deal.
To add/process into this maybe:
- Fix setup race when config entry is in a setup retry state ([@bdraco] - [#73145]) (noteworthy)
- Prime platform.uname cache at startup to fix blocking subprocess in the event loop ([@bdraco] - [#73975]) (noteworthy)
- Check if requirements are installed in the executor ([@bdraco] - [#71611]) (noteworthy)
Our YAML & JSON tooling improved, using faster libraries and methods.
JSON is used internally and for communication with the frontend, which is
A LOT snappier now. If you use lots of YAML, you will undoubtedly notice this
when starting Home Assistant or reloading things like your automations 🚀.

performance improvements that have been made. This release, it is a big deal.
For many releases [@bdraco] has been analyzing every single aspect of
Home Assistant and manages to make it faster every single release, but
an exceptional progress has been made this release!
The first one is that our YAML & JSON tooling has been optimized/replaced,
with faster libraries and methods. If you use lots of YAML configuration,
you will seriously notice this a lot when starting Home Assistant or
when reloading things like your automations 🚀. JSON is used a lot internally
and for communication with the frontend or APIs, making things A LOT snappier.
Devices with an integration error during startup, that are able to self recover,
Devices with an integration error during startup that can self-recover
will now do that instantly as soon as the device is discovered.
We now use an better and faster encryption method for the HomeKit Accessory
Protocol (HAP). This improves the performance of the HomeKit, HomeKit Controller,
We now use a better and faster encryption method for the HomeKit Accessory
Protocol (HAP). It improves the performance of the HomeKit, HomeKit Controller,
and Apple TV integrations and prepares Home Assistant for iOS 16.
Lastly, [@pvizeli] has been working hard to ship Home Assistant on Python 3.10!
Which also brings quite an performance improvement. If you are running the Home
Assistant Operating System or use our container installation method, you will
automatically get this, no need to do anything. 🚀
