+
+## Changes in 3.0.2
+
+This SDK is using 2020-05-01 version of the API
+
+- The Media Services account now supports system managed identities.
+- When a Media Services account has a managed identity, it can be used to enable encryption at REST with a customer managed key.
+- When a Media Services account has a managed identity, it can be used to access the attached storage accounts using the managed identity.
+- Live event added an Allocate action to put it into StandBy state.
+- Updates to most live event properties are now allowed when the live event is in stopped and standby state.
+- Users can specify a prefix for the static hostname for the live event's input and preview URLs.
+- VanityUrl is now called useStaticHostName to better reflect the intent of the property.
+- When an encoding live event receives input with aspect ratio different from the one specified in the preset, stretch mode allows customers to specify the stretching behavior for the output.
+- Encoding live events can now be configured to output constant fragment size of between 0.5 to 20 seconds.
+- Live transcription APIs allow customers to turn on live transcription for one of the many supported languages.
+- Added property Video.SyncMode which controls the frame rate of the encoded output. Supported values are "Auto", "Passthrough", "Cfr", and "Vfr".
+- Added Property JpgImage.SpriteColumn, which can be used to set the number of columns used in thumbnail sprite image
+- Added CopyAllBitrateNonInterleaved Preset, which can be used to clip an existing asset or convert a group of key frame (GOP) aligned MP4 files as an asset that can be streamed.
+- Added UtcClipTime class, which specifies the clip time as a Utc time position in the media file during a job creation.
+- Added the “Mode” property to Audio/VideoAnalyzerPresets, exposing a new Basic Mode that only performs transcription and caption generation.
+
+### Breaking changes:
+
+- VanityUrl property on LiveEvent is now called UseStaticHostName to better reflect the intent of the property.
+- SubscriptionMediaService class has been removed in favor of MediaService class. SubscriptionMediaService is a duplicate of MediaService class.
+- Basic and Standard live encoding types referred to the same live event type. Basic LiveEventEncodingType has now been removed. Supported encoding types are Standard, Premium1080p or None.
