# Bond Core v4.27.50 Beta Release Notes

**Release Date:** January 9, 2026  
**Release Type:** Beta

* * *

## Mate Remotes (MT-1500)

_Changes since v4.27.8_

### Bug Fixes

- **Alpha Motor Support:** Fixed an issue where Alpha motor control was broken in recent firmware. ([#3671](https://github.com/ZolibraBond/bond-core/pull/3671))

- **Low Battery Behavior:** Mate now properly displays the critical battery warning and prevents unexpected shutdowns during low-battery operation. ([#3661](https://github.com/ZolibraBond/bond-core/pull/3661))

- **Bluetooth Reliability:** Fixed intermittent Bluetooth connectivity issues where Mate would become unresponsive after disconnecting from the mobile app. The device now reliably accepts reconnection attempts without requiring a manual reset. ([#3663](https://github.com/ZolibraBond/bond-core/pull/3663), [#3656](https://github.com/ZolibraBond/bond-core/pull/3656))

- **Button Backlight:** Fixed an issue where the button backlights would briefly turn on while Mate was fading to sleep (when Auto Brightness is disabled). ([#3643](https://github.com/ZolibraBond/bond-core/pull/3643))

### New Features

- **Locate Device:** Added device locate/identify animation that displays on the LED matrix when triggered from the app. _(Requires forthcoming app update.)_ ([#3650](https://github.com/ZolibraBond/bond-core/pull/3650))

## Bond Bridge (BD-1000) & Bond Bridge Pro (BD-1750)

_Changes since v4.27.6-beta_

### Bug Fixes

- **Draper Discovery:** Fixed an issue where Draper discovery would fill the device table with out-of-subnet devices, preventing in-subnet devices from being discovered. Only affects installations with multiple IP Gateways where total device count exceeds 50. ([#3629](https://github.com/ZolibraBond/bond-core/pull/3629))

- **Hash Updates:** Fixed an issue where device/group state changes were not always detected by integrations. ([#3603](https://github.com/ZolibraBond/bond-core/pull/3603))

### New Features

- **Dendo Shade Presets:** Dendo (RMS115) shade preset positions (A, Center, B) now work with schedules and Home Assistant. ([#3659](https://github.com/ZolibraBond/bond-core/pull/3659))

- **SelectBlinds & 3 Day Blinds:** Added support for SelectBlinds Bridge and 3 Day Blinds Bridge integrations on Bond Bridge Pro. ([#3614](https://github.com/ZolibraBond/bond-core/pull/3614))

### Improvements

- **HTTP Performance:** Improved HTTP API responsiveness, particularly noticeable when sending many commands in quick succession. ([#3664](https://github.com/ZolibraBond/bond-core/pull/3664))

## Testing Recommendations (Beta)

1. **Mate Bluetooth:** Test repeated connect/disconnect cycles from the mobile app; verify reconnection works reliably.
2. **Mate Low Battery:** Verify critical battery warning displays properly with depleted batteries.
3. **Dendo Presets:** Test scheduling preset positions (A/Center/B) via the app or Home Assistant.
