Ably-js v2.28.0: end to end encryption for annotation data payloads
CLIENT LIBRARY SDK IMPROVEMENT
Ably-js 2.28.0 is released, adding end to end encryption for annotation data payloads. These were previously not covered by e2e encryption to allow serverside summaries of certain aggregation types, but those types have been removed in favour of ones which store aggregatable information outside of the data payload, so we can now enable e2e encryption on annotation payloads. You don't need to do anything other than use the new library version to take advantage of this; annotations published on encrypted channels by this library will now automatically have any payloads encrypted, and can be successfully decrypted by any version of ably-js that can handle annotations (since 2.13.0).
