Highlights

Known issues

some protocol version 3.4 devices stop responding due to too many communication errors after some time since 2026.4.0. This version continues to make improvements to avoid communication errors, but since the root cause is not fully understood the fixes in this version are not considered a final fix for the issue.
the infrared platform is undergoing incompatible changes again in HA 2026.6. At this stage, I believe only unit tests will be affected.
a service to send learned remote commands through the infrared platform was added a couple of versions ago, but is not fully working, so is not advertised in the docs.
lights that use a masked dp to control multiple lights have synchronization problems when changed together. Although fixed in the previous version, this fix needed to be partially reverted due to side effects on devices that do not mix entities in the same dp.

HA Scenes that affect two entities from the same device sharing the same dp were previously improved by #4986, but due to adverse impact on other devices with multiple entities that have their own dps this has been reverted for this release.
daizuki_heatpump: deprecated entities from December have been removed, use the climate entity instead.
watermark switches have been standardized for translation. Some variant naming such as "OSD watermark" and "Timestamp" has been updated. Migration is provided, but may not cover all uses.
timer switches have been standardized for translation. Some variant naming has been updated. Migration is provided, but may not cover all uses.
recording_mode selects have been standardized for translation. Some variant naming and option naming has been updated. Options are standardized to "event" and "continuous". If you have automations changing these selects, please check as the migrations only cover entity naming.
night_vision selects have been standardized for translation. Some variant naming and option naming has been updated. Options are standardized to "on", "off" and "auto". If you have automations changing these selects, please check as the migrations only cover entity naming.
This will be the last version to work on HA 2026.5, as HA seems to have abandoned deprecation periods and is introducing breaking changes with every major release now.
