Features Releasing to Stable

Persistent Quota Deprecation Contributors:  cfredric@, mek@, ayui@ ChromeStatus     Bug      Intent to Deprecate and Remove Deprecate and remove support for the legacy window.PERSISTENT quota type. Unlike other removals of old, little-used storage features that only Chromium supports, this one shouldn't break anyone's code. Going forward, webkitRequestFileSystem will simply ignore the type parameter, and requests for PERSISTENT storage will create regular, non-persistent storage. Legacy quota API navigator.webkitPersistentStorage will be an alias to navigator.webkitTemporaryStorage. Deprecated quota API webkitStorageInfo methods will also ignore the type parameter.

Support "Bring Your Own Buffer" reader for SerialPort's ReadableStreams Contributors:  reillyg@ ChromeStatus     Bug     Spec     Intent to Ship The SerialPort interface provides a ReadableStream and WritableStream. This change updates the underlying data source for the ReadableStream to make it a readable byte stream.  "Bring Your Own Buffer" BYOB readers allow developers to specify the buffer into which data is read instead of the stream allocating a buffer for each chunk. In addition to the potential reduction in memory pressure, this allows scripts to control how much data is received in a chunk, as the stream cannot return more than there is space for in the provided buffer.

Please reach out with any questions, comments or suggestions.
