Note: This release failed to publish properly on Android (see #1155). You will need to use v0.28.1 instead.

FirefoxAccount.ensureCapabilities now takes a set of capabilities
as a parameter. All the device registered "capabilities" such as Send
Tab will be replaced by the passed set of new capabilities.

PushManager.verifyConnection() now returns a boolean. true
indicates the connection is valid and no action required, false
indicates that the connection is invalid. All existing subscriptions
have been dropped. The caller should send a pushsubscriptionchange
to all known apps. (This is due to the fact that the Push API does
not have a way to send just the new endpoint to the client PWA.)
#1114
PushManager.unsubscribe(...) now will only unsubscribe a single
channel. It will return false if no channel is specified or if the
channel was already deleted. To delete all channels for a given user,
call PushManager.unsubscribeAll().
#889

Native libraries should now have debug symbols stripped by default,
resulting in significantly smaller package size for consuming
applications. A test was also added to CI to ensure that this
does not regress in future.
