Please test your aplite apps thoroughly after rebuilding with SDK 3.8. * Added Pebble Health! * No API is yet available to access health information, but one will be added in an upcoming release. * Improved the rendering of ``NumberWindow``. * Fixed a race when exiting an ``ActionMenuLevel``. * Timeline pins no longer require icons, and will pick a sane default. * 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 a memory leak in ``DictationSession``. * Restored the double vibration when _disabling_ Quiet Time (enabling is still a single vibration). * Restored the missing "Call back" button to iOS missed call pins. * Assorted minor design changes. ### Changes to SDK * Deprecated `png`, `pbi` and `pbi8` in favor of a new `bitmap` resource type. [Read more on our blog!](/blog/2015/12/02/Bitmap-Resources/). * 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. * Font resources are now somewhat smaller than they used to be. ### Changes to Pebble Tool SDK 3.8 is the first version exclusively available via the [new pebble tool](/blog/2015/12/01/A-New-Pebble-Tool/). No future SDK packages will contain the tool, or any changes to the tool. ### Changes to Emulator/Phonesim As with the pebble tool, the emulator and phone simulator are no longer coupled to the SDK.
