# Pebble SDK 2.0 BETA6 - Changelog

Source: https://developer.repebble.com/sdk/changelogs/2.0-BETA6/

_Release Date: January 17 2014_

- Pebble SDK 2.0 is currently in BETA and intended for developers only.
- Applications written for Pebble 1.x are not compatible with SDK 2.0
- If a 2.0 version of an application exists, the Pebble mobile applications will automatically install it when when a user upgrades her/his Pebble.

> **IMPORTANT NOTES FOR iOS Users** :
> 
> - You must delete the Pebble app on your phone before installing this new version. It will now be called "Pebble Dev" and not "Pebble.". You must also re-install all of your JavaScript apps after installing this new version.
> 
> - iPhone5S, iPad Air and Retina iPad Mini users will need to manually pair in the **Settings** of the phone.

## What has changed since BETA5

Overview:

- The iOS Application distributed with BETA6 includes the new Pebble appstore
- The firmware fixes a number of hard to reproduce crashes with system timers. This will fix a lot of the "Dangerously rebooting" Pebble crashes.

### Known Problems and limitations

- `getAccountToken()` (in PebbleKit JS) is not working yet. It currently returns a random string. In an upcoming update (before 2.0) it will return a unique token linked to the Pebble user account. This is tied with appstore functionnalities and not available yet in this beta build.
- The bugs that were reported on datalogging-iOS on BETA5 are not fixed yet in this release

### Changes for Firmware:

- Rework the system timer to fix all timer related crashes
- Add support for Pebble Steel LED to show charging status
- Round rather than floor the battery charge percentage
- Reverted timings for stm32 for 64MHz system clock based on stable 16Hz SPI clock. Fixes display flicker at 30Hz, as well as saving power at the lower system clock (80-\>64) and sleeping more often due to faster display updates.
- Fix a crash when canceling the bluetooth pairing dialog
- Fix a bug where pushing a window in a window\_unload callback would cause a crash
- Export AccelData structure in the API doc
- Vibrate when an app or watchface is installed
- Fix a bug where the phone modal window would not update properly
- Fix the light threshold for Pebble Steel

### Changes for Pebble iOS App:

- Added the Pebble appstore
- Added support for In-App Notifications
- Add support for migrating 1.x apps into 2.0 apps
- Fix a bug where the iOS app could crash when you switch away from a JavaScript app that has an ongoing network connection
- PebbleKit JS iOS: sendAppMessage() now returns a transaction id

### Changes for Pebble Android App:

- No changes.

### Changes for PebbleKit iOS:

- add isNewer convenience call to PBWatch+Version
- move NSJSONSerialization helper to PebbleVendor
- add isEqualVersionOnly to just compare version number components, ignoring timestamp & hash

### Changes for PebbleKit Android:

- No changes.

### Changes for SDK Tools:

- Fix spelling in an error message (s/Insure/Ensure/)

### Changes for Examples:

- No changes.

### Changes for Documentation:

- Fix a 404 on the pebble tool link in the JS guide
- Fix the persistence guide to reflect the new standardized parameters orders
- Fix a typo in the title of the UI framework guide
- Added designer resources in the UX design chapter
