Save the time the tracker adds a new changed id and use that to compare the age of the record on the server vs the age of the local change to decide if it's server wins or client wins. Fix up various direct uses of changedIDs to use the API and make the save-to-disk lazy to avoid excessive writes. Add a test to make sure addChangedID only increases in time.
Store a HMAC with the encrypted symmetric key instead of just the wrapped key and verify that the HMAC matches before unwrapping. Test that normal getting works and a tampered payload/HMAC fails but succeeds on restoring the correct HMAC.
Generate a SHA256 HAMC hex string from the base64 ciphertext and base64 symmetric key. Generate a HMAC key from the symmetric key and cache them together when unwrapping. Refactor the Utils.sha1 to share the same digest code.

Get rid of get/setInfo on ClientEngine and ClientStore and expose functions to read/modify client data: stats, clearCommands, sendCommand. Also expose the local client information as local[ID,Name,Type,Commands] and rework the storage to use these instead of trying to keep the JS object clients entry in sync with prefs, etc. Update users of the old interface (service/tabs/chrome) to use the new local*. Set the client type based on app id instead of from each app's overlay.
Get rid of Filters and automatically JSON.stringify PUT/POST data that aren't strings, so plain Records can be passed in to PUT and POST. This leverages toJSON of Records to provide an object that can be serialized. Fix up client record serialize/deserialize to still escape/unescape non-ASCII.
Switch to newline mode when using a collection record handler, and look for newlines! Easy! Update test to provide newline-separated strings instead of JSON.
Get rid of lastChannel and return a String object from _request with additional properties of status, succeeded, headers -- even if the response was handled by cache. Update engines to check for non-success and throw the failure. Update tests to use these additional properties instead of lastChannel, etc.
Make sure we generate ASCII data for upload by escaping on serialize and unescaping on deserialize. Test to make sure serialized data is ASCII and the original records aren't modified by serialize.
Remove short-circuit logic of comparing number of keys for deepEquals and iterate through each key on both objects to make sure both have the same value.
Incrementally process records as the collection finds record boundaries and converts them to records for the engine to use. Get rid of the collection iterator and original RecordParser. Add tests for incremental record parsing and remove old iter tests.
Internally store .lastSync as a string but keep exposing set/getters as float values. parseFloat takes both strings and numbers and gives a number.
