## What has changed since BETA6

Overview:

 - More random crashes fixed in the firmware
 - Seriously improved datalogging on iOS (and some bugfixes on Android)
 - Fixed the URL scheme to install Pebble applications. It did not work in Beta6.
 - Added support for `getAccountToken()` in PebbleKit JS (iOS only at the moment)
 - iOS application and PebbleKit iOS are now 64 bits compatible
 - iOS application does not crash on iPhone 4 anymore
 - Some breaking changes in PebbleKit iOS: We cannot use NSNumber categories in 64 bit because their size is unknown. We added a new PBNumber class. This class is returned if you use the NSNumber Pebble category.

### Known Problems and limitations

 - Android does not include the Pebble appstore yet
 - PebbleKit iOS apps may see error messages about parsing firmware in their logs. This will be removed soon and does not impact anything in PebbleKit iOS.

### Changes for Firmware:

 - fix bugs with modal windows over fullscreen apps
 - fix bugs where action bar buttons could get "stuck"
 - reduced the power used by Pebble Steel LEDs
 - fix some data logging corruption issues on Pebble
 - fix a bug where the time of a notification would not be displayed properly
 - adjusted the battery charged thresholds so that Pebble Steel turns green when apps show 100%
 - fix a bug where you could get 110% battery
 - fix a bug where datalogging session could be incompletely initialized when pushed
 - fix a bug that could happen when looking for notifications
 - fix a bug where some original Pebbles (ev2_4) would never hit 100% battery
 - fix infinite loop if you push a modal while one is closing
 - fix some button problems on Pebble Steel

### Changes for Pebble iOS App:

 - added support for 64bits compilation
 - fix a bug where 64 bit devices would not display the bluetooth accessory picker
 - native login / signup screen
 - fix some button sizes to display text properly
 - calculate the area of the buttons on the left menu to highlight them dynamically
 - data logging: do not print error messages for partially fetched data - unless we are actually done
 - fix some bugs around the Bluetooth accessory picker
 - better management of the screens stack in onboarding process. allows users to go back.
 - do not display icon for watchfaces in the my pebble screen
 - fix bug where appstore url-scheme would not work
 - add link to terms and conditions
 - deal with timeout errors while installing apps
 - downloading apps in the Caches directory instead of Documents since that one gets pruned automatically by the system (Fixes pebblekit#39)
 - only allow to start dragging the center view if you start dragging from the left edge
 - fix crash for iPhone 4 users
 - fix bug where datalogging would try to send data to the Pebble app (instead of 3rd party apps)
 - lazy loading the web appstore views to improve loading speed
 - sort apps alphabetically in the locker
 - memory optimization to stay in the background longer

 - fix a bug where the configuration view was not sometimes not dismissed
 - rename the "Done" button of the configuration view to "Cancel"
 - send empty string back to the JS if the user cancels the configuration view (as per documentation)
 - only show the "notifications not set up" if there's a watch connected
 - fix a JS bug where in some conditions the 'showConfiguration' event might be fired before the 'ready' event

### Changes for Pebble Android App:

 - Datalogging: if a session contains bad data, just remove it at startup

### Changes for PebbleKit iOS:

 - PebbleKit iOS is now 64 bits (armv7s) compatible
 - We cannot use NSNumber categories in 64 bit because their size is unknown. We added a new PBNumber class. This class is returned if you use the NSNumber Pebble category.
