# Pebble SDK 3.8-beta10 - Changelog

Source: https://developer.repebble.com/sdk/changelogs/3.8-beta10/

_Release Date: December 9 2015_

This is a pre-release version of the Pebble SDK. Only changes since beta8 are included.

### Changes to Firmware

- Resolved an issue causing alarms to not vibrate in standby mode
- Added `shortSubtitle` property to all timeline layouts. 
  - This string, if provided, will be used as the subtitle in the timeline list view.
- Added a `displayTime` enum to the timeline weather layout. 
  - If `none`, it will not display a time. If `pin`, it will display the time of the pin in the title. The default is `pin`.
- Timeline pins were no longer last updated in 1970.
- Resolved some minor layout issues.

### Changes to SDK

- Added `PBL_MICROPHONE` and `PBL_SMARTSTRAP` macros, which will be defined when a microphone or a smartstrap connector is available, respectively. Note that the runtime availability of the services should still be tested, as the presence of hardware is not sufficient.
- Removed spuriously exported `_EMOJI` fonts. Emoji symbols will display in system fonts as before.
- Fixed an issue causing the generation of indexed PBIs containing non-black transparent pixels to fail.
