 - **Repo Privileges**
 We have opened up our access rights and have expanded our GitHub privileges to some of the external members of our community.  This gives these community members direct write access to the ResearchKit repository and merge pull requests.
 
 - **Schedule Changes**
 Previously the ResearchKit framework pushed to our master and stable branches simultaneously.  With this release we want to allow for more participation from the community so to accomplish this, we will push to the stable branch some time after our initial push to master.  This will enable the community to check out the new features, provide suggestions and submit pull requests.  During this time between master and stable, we will complete accessibility, localization and QA sweeps of the code so if you make contributions during this time, they will be reflected in the official stable release branch to follow.

 - **Speech Recognition**
 The speech recognition task lets developers present participants with either an image for users to describe or a block of text for users to repeat.  The participant will press record while they follow the prompt and when they have completed recording, a transcription will appear for them to edit if they feel anything was transcribed incorrectly.  The task will generate results that include an audio recording of what the participant said, a transcription of the output from the speech to text engine and the transcription which is editable by the participant if they made any changes to the output.

 The Amsler Grid test is a task that can be used to collect data about a users vision.
