Pebble SDK 2.5 - Changelog

Release Date: September 18 2014

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.

  • Added support for uuid_equal and uuid_to_string.

  • 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 that would cause the sample rate of the accelerometer to be reset when subscribing.

  • Added support for notification dismissal on iOS8.

  • Fixed a reset and other various bugs related to Data Logging.
