>     1.
> 
> String Metric Type - Enhancements
>         * /strings endpoint was enhanced with querying capabilities similar
>         to other metric types, including tag related features (
>         HWKMETRICS-402 )
>         * The endpoints under /strings are still experimental, so changes
>         which break backwards compatibility could be introduced in future
>         releases. The experimental tag allows time for feedback to better
>         determine what the API should be.
>     2.

> */stats & */raw Replace */data - second deprecation warning!
>         * */data has been deprecated and functionality split into two single
>         purpose endpoints, this is applicable for all metric types (gauge,
>         counter, availability, and string)
>         * */stats endpoints return bucketed, statistical or query-time
>         aggregated data
>         * */raw endpoints accept and return raw data for a metric
>         * Please update your code to use the new endpoints and follow the
>         release notes for more details regarding removal.
>         * For more details: HWKMETRICS-24 , HWKMETRICS-57
>     3.
> 
> REST API Updates
>         * Empty buckets are now reported with default values and no samples (
>         HWKMETRICS-345 )
>         * Rate of change stats can be retrieved for Gauge metrics. This
>         feature was exclusive for Counter metrics but was expanded to Gauge
>         metrics. The rates are computed at query time based on stored data (
>         HWKMETRICS-365 )
>         * Min and max timestamps of stored datapoints are now returned when
>         querying for metric definitions ( HWKMETRICS-383 )
>         * The endpoint for fetching rates now supports standard query
>         parameters and sort behavior ( HWKMETRICS-390 )
>     4.
> 
> Hawkular Metrics - Hawkular Services distribution
>         * Hawkular Metrics distribution build for inclusion in Hawkular
>         Services is now independent of Hawkular Accounts.
>         * Only for this distribution, the authentication is done at container
>         level and tenant id header becomes required.
>         * For more details: HWKMETRICS-399 , HWKMETRICS-401
