Pebble SDK 2.5 - Changelog	2014-09-18

If you are upgrading from a previous version of the SDK, you will need to run the pebble clean command before using the SDK 2.5 with your project.

##Major Changes

• FW 2.5 includes an optimized version of snprintf (and related functions like APP_LOG, etc) that does not support some length format specifiers previously supported (%hh, %ll, %j, %z, %t). The list of supported specifiers has been updated in the snprintf documentation. For those of you that use these previously-supported specifiers, please do not hesitate to contact us and we'd be happy to assist you with updating your code.
• Added compass support.
• Enforced versionLabel formatting in appinfo.json in preparation for app auto updates.
• Added support for Pebble app relaunch on iOS when a Pebble watch is in proximity.
• Added notification dismissal support on iOS8.
• Added emoji support to Pebble notifications and system fonts.

Detailed List of Changes:

Changes for Firmware:

• Added functions heap_bytes_free and heap_bytes_used to view current heap memory usage.
• Added support for uuid_equal and uuid_to_string.
• Added function accel_raw_data_service_subscribe to get accelerometer data with a single timestamp for all samples (significantly reduces memory usage for apps that do not depend on timestamps).
• Added compass support.
• Added emoji support to Pebble notifications and system fonts GOTHIC_24_BOLD, GOTHIC_18 and GOTHIC_18_BOLD.
• Fixed a bug that would cause a crash if a screen shot was taken while one was already in progress.

• Fixed a bug with accel_service that could result in memory being freed twice.
• Fixed a bug where Golf API would show stale information on disconnect.
• Fixed a bug that prevented calling menu_layer_set_selected_index before menu_layer_set_callbacks.
• Fixed a bug which would sometimes cause the command line logging tool to crash when a watchapp crashed.
• Fixed a bug that would cause the sample rate of the accelerometer to be reset when subscribing.
• Added support for Pebble app relaunch on iOS when a Pebble watch is in proximity.
• Added support for notification dismissal on iOS8.
• Fixed numerous bluetooth reliability & connection issues.
• Fixed a reset and other various bugs related to Data Logging.
• Fixed a bug that allowed backing out of FW update screen.
• Fixed a bug that would cause animations between windows to be slow.
